The Kaypro 2000 had two notable changes during its lifetime.  Initially in the spring of 1985 it came with 256K of RAM with upgrade options of 512K and 768K. If configured with 768K then the upper 128K could be used as a RamDisk since the operating system was limited to the lower 640K. In the summer of 1986 the base configuration was changed to include 768K of RAM.  
Press release cover letter dated April 22, 1985.


The originally released Kaypro 2000 had a large border around the lcd screen. Typically, this border had a green color.  My guess would be that they had designed the machine to have a larger screen than the 80 by 25 character screen it initially shipped with. Having lived during this time I remember the challenges that manufacturers had during this time producing flat panel displays with acceptable numbers of defective pixels. They likely settled with a smaller screen to keep the cost down and supply higher.

===Screen Size Change===

Typically, the small screen had a had a green colored border.  My guess would be that they had designed the machine to have a larger screen than the smaller screen it initially shipped with. Having lived during this time I remember the challenges that manufacturers had producing flat panel displays with acceptable numbers of defective pixels. They likely settled with a smaller screen to keep the cost down and supply higher.  
 
When the base memory was changed to 768K they also upgraded the screen to one that was “28% larger”.  These later machines have a screen that appears more appropriately sized to the designed area, it had a black border.  It appears that the number of characters was not changed with the larger screen since they both have 80 by 25 characters.  In the news section of this page it is hinted that the larger screen required more memory which isn't likely since the resolution did not change.  The larger screen has a slightly better contrast which does make it more readable but it is still a challenge.
 
The Kaypro 16 had a 80 by 40 display like the previous CPM Kaypros. So the Kaypro 2000 always had a slightly disadvantaged screen compared to the luggable versions, especially when you consider screen contrast.

The owner of this machine states: "I believe it's an Axonics unit out of Utah." (eBay, gameboy3800yt, 8 June 2026)<br>


When the base memory was changed to 768K they also upgraded the screen to one that was “28% larger”.  These letter machines have a screen that appears more appropriately sized to the designed area.  While I do not have one of these 2nd generation Kaypro 2000s to confirm this it is likely that they have a display resolution of about 80 by 32 characters based on the 28% increase.  The Kaypro 16 had a 80 by 40 display like the previous CPM Kaypros. So the Kaypro 2000 always had a slight disadvantaged screen compared to the luggable versions.  
This is a review of the Bondwell 2 laptop:<br>
"The poor character quality on the screen can
probably be remedied by an electroluminescent screen

"The Kaypro 2000 is a lap-top computer much like the Data General One. There's a standard model that is also available with memory and modem upgrades. The basic Kaypro 2000 comes with 256K of RAM and one 720K 3 1/2-inch floppy drive. The enhanced version has 768K, a 3 1/2-inch drive, and an internal 1200-baud modem."<br>

==Manufacturing==
In the press there was talk of a partnership between [[Mitsui connection|Mitsui]] and Kaypro to develop a small laptop. Mitsui ended up not making the Kaypro 2000. In an interview in 2025 for the Floppy Days Podcast David Kay says that Citizen made the 2000 for Kaypro.<br>

==Derived Machine==
The French computer maker "SMT Goupil" produced the "Club" computer which appears to be a derivative of the Kaypro 2000.  It featured 2 floppy drives.

Kaypro 2000

Model Number 81-040 (Some units have a P/N 81-043 sticker added on the bottom)


Press release cover letter dated April 22, 1985.

The Kaypro 2000 is Kaypro's lucky number. The company's new lap top computer is priced under $2000, targeted at the Fortune 2000 executive, and designed to take the user into the next century. ...
The Kaypro 2000 is IBM compatible, of course. In fact, it is Kaypro's fourth IBM compatible machine. In the last three months Kaypro has brought out the Kaypro 16, the Kaypro 162, the 286i AT-compatible, and now the Kaypro 2000 in quick succession, making Kaypro a key player in the personal computer market.
("For the Fortune 2000, the Kaypro 2000", Kaypro Press Release)

The Kaypro 2000 had two notable changes during its lifetime. Initially in the spring of 1985 it came with 256K of RAM with upgrade options of 512K and 768K. If configured with 768K then the upper 128K could be used as a RamDisk since the operating system was limited to the lower 640K. The start-up RAM check only tests the lower 640K and doesn't report the entire memory of the 768K version. In the summer of 1986 the base configuration was changed to include 768K of RAM.

Screen Size Change

The originally released Kaypro 2000 had a large border around the LCD screen. Typically, the small screen had a had a green colored border. My guess would be that they had designed the machine to have a larger screen than the smaller screen it initially shipped with. Having lived during this time I remember the challenges that manufacturers had producing flat panel displays with acceptable numbers of defective pixels. They likely settled with a smaller screen to keep the cost down and supply higher.

When the base memory was changed to 768K they also upgraded the screen to one that was “28% larger”. These later machines have a screen that appears more appropriately sized to the designed area, it had a black border. It appears that the number of characters was not changed with the larger screen since they both have 80 by 25 characters. In the news section of this page it is hinted that the larger screen required more memory which isn't likely since the resolution did not change. The larger screen has a slightly better contrast which does make it more readable but it is still a challenge.

The Kaypro 16 had a 80 by 40 display like the previous CPM Kaypros. So the Kaypro 2000 always had a slightly disadvantaged screen compared to the luggable versions, especially when you consider screen contrast.

The owner of this machine states: "I believe it's an Axonics unit out of Utah." (eBay, gameboy3800yt, 8 June 2026)

This is a review of the Bondwell 2 laptop:
"The poor character quality on the screen can probably be remedied by an electroluminescent screen upgrade available from the Axonics Corporation, 417 Wakara Way, Salt Lake City, UT 84108 ($300, includes shipping).
(Morrow Owners' Review, June/July 1986)

News

"Kaypro Corp., Solana Beach, Calif., said it had introduced a new computer, the 2000, which is priced under $2,000."
(New York Times, April 9, 1985)


Although the Kaypro 2000 comes with 256K RAM, you may want additional memory. At your option, you can have the factory install RAM chips to bring the system up to a total of 768K RAM. You could install the extra memory yourself, but letting the factory handle installation protects your warranty

With the full 768K ($195), spreadsheet and disk copying operations are much more convenient. And because the extra memory is internal, you aren't tied to the base unit. MS-DOS cannot use memory above its 640K boundary, but Kaypro includes RAM disk software that can make use of memory above 640K.

If you want to add an internal modem ($295), Kaypro offers a 1200-baud Hayes-compatible modem. The internal modem snaps into a connector on the mainboard and fits completely inside the 2000's casing, another Kaypro option is the serial-to-parallel printer interface ($65). This universal interface allows almost every common printer with a standard Centronics parallel configuration to be connected directly to the 2000's serial port.
(Profiles, January 1986)

"The Kaypro 2000 is a lap-top computer much like the Data General One. There's a standard model that is also available with memory and modem upgrades. The basic Kaypro 2000 comes with 256K of RAM and one 720K 3 1/2-inch floppy drive. The enhanced version has 768K, a 3 1/2-inch drive, and an internal 1200-baud modem."
(Profiles, January 1986)

With the introduction of their new 286i (the IBM AT clone) and now the Kaypro 2000 (the IBM-compatible portable lap computer) Kaypro seems to be headed one way--toward the business community.

The latest information we have from Kaypro regarding the 2000 is as follows:

The 2000 uses the IBM-compatible MS/DOS operating system and comes with an 80 column by 25 line liquid crystal display screen, built for Kaypro in Japan. It has 640 x 200 pixels and a backlight for improved legibility.

One of the features is the detachable keyboard. It still connects with a cord, but it doesn't confine the operator to any one position and makes the screen easier to read.

The standard 256k is expandable to 768k, and the single 3.5 inch disk drive allows 720k of storage on each disk. The 2000 has an 8080 processor and runs at 4.7 Mhz with I/0 for RS232 and parallel ports. Power is supplied by a rechargeable battery with up to four hours' use of computer time. Peripherals may be added, including a 5.25 or external hard drive.

Total weight of the Kaypro 2000 is eleven (11) pounds.

The bundled software includes the full MicroPro (Star) package and GW Basic.

The price for this laptop is $1995.00, and delivery is scheduled for some time in June.
(Kugram, May-Jun 1985)

"The Kaypro 2000's latest improvement, a 28% larger screen, takes less time to read. therefore, faster screen updates are necessary for speed readers. So the Kaypro 2000 now comes with a standard 768K RAM and RAM-disk software. Operating software within RAM is dramatically faster and more energy efficient than continually accessing a disk drive."
(Kugram, Jul-Aug 1986)


Manufacturing

In the press there was talk of a partnership between Mitsui and Kaypro to develop a small laptop. Mitsui ended up not making the Kaypro 2000. In an interview in 2025 for the Floppy Days Podcast David Kay says that Citizen made the 2000 for Kaypro.
(David Kay Interview #2)

Derived Machine

The French computer maker "SMT Goupil" produced the "Club" computer which appears to be a derivative of the Kaypro 2000. It featured 2 floppy drives.


Note that this port is changed to serve as an adapter connection on the Club.

Kaypro 2000 Base Unit

Model # 81-041


From the Preliminary Price Sheet


"The base station for the 2000 is close to completion, and plans for the modem for this computer are still in the discussion stage. It is not yet certain whether Kaypro will offer a 300- or 1200-baud version, nor whether it will be internal or external. Also undetermined as of now is whether the modem will be part of the standard package or offered as an option."
Kugram Vol.3 No.4

"The optional base unit ($795) is an expansion chassis that holds two full-length expansion cards and has room for two half-height 5.25-inch disk drives, or one half-height 5.25 floppy and a half-height hard disk. With the base unit, special-purpose cards can be used with the 2000, and direct conversion from 3.25- to 5 .25-inch diskettes is a snap. It also features both serial and parallel ports, freeing you from reliance on the single serial port on the 2000. Interfacing the 2000 with the base unit is simple and straightforward. On the bottom of the 2000 is a 5.5inch hard rubber strip. Slip that protective strip away and you'll see two lines of 50 pins. This 100-pin maleto-female interface seats securely atop the corresponding pin slots on the upper surface of the base unit. No cables are needed."
(Profiles, January 1986)

Base Unit....$795.
Description: Expansion chassis for customers who want to add special functions with IBM cards. Also houses added disk drives. Not required for typical users.

Features: 2 IBM slots, one 5.25" disk drive, space for an additional drive (5.25", or 3.5", or hard disk), serial port, parallel port.

How it works: Kaypro 2000 computer fits on top of Base Unit and locks into a matching nest. All connections are made automatically. No cables are necessary.

This power supply matches the power supplies in the CPM Kaypro machines.

Kaypro 2000 Multi Adapter

Part Number: 81-790


This is the Hercules Color Card (GB200 Rev B)
that was installed in my Multi Adapter


Image from the Preliminary Price List
Different Design from production

"Similarly, the multi-adapter unit ($155) allows the 2000 to snap directly into place. With the multi-adapter, you can connect external disk drives and an RGB monitor. The multi-adapter includes a 5.25-inch disk port, a 3.5-inch disk port, a parallel port, and one half-length slot for a video card. Although the multiadapter will accept any half-length video board, Kaypro recommends using the Persyst II color card."
(Profiles, January 1986)

Multi-Adapter....$155.
Description: Module that allows Kaypro 2000 to connect to external disk drives and RGB color video monitor without Base Unit.

Features: 5.25" disk port, 3.5" disk port, parallel port and video card slot.

How it works: Snap Adapter into bottom of Kaypro 2000 (Computer will tilt up at slight angle.) Plug disk dirves and parellel printer into connection on rear of Adapter.

Kaypro 2000 External Floppys

3.5" Floppy

If you do want another disk drive, Kaypro offers an ultra-small disk drive (1 x 4.5 x 6 inches) in the 3.5inch format. This external drive is enclosed in a brushed aluminum black casing, so it matches the 2000. Because this disk drive (priced at $295) is self contained, it is as portable as the 2000.

To use the optional 3.5-inch external disk drive, you simply connect the cable that comes with it into the multi-adapter's 3.5-inch port. Like the 2000, this external drive is battery powered.
(Profiles, January 1986)

Additional 3.5" Disk....$295.
Description: Ultra small 3.5" 720K external drive in portable brushed aluminum enclosure.

How it works: Cable (included) plugs into Disk Adapter 3.5" port. Battery powered, fits easily in luggage for travel. (This drive not needed for same capacity as IBM-PC.)

Labeled Type

 Image from an eBay listing.
Unlabeled Type

This type appears to be the same mechanism that is in the K2000 with an extra shell around it and with additional circuitry to allow for connecting to the Multi-Adapter.

The screws to open it appear to be under some of the feet.
This appears to be the type described in the Profiles article.


From the Preliminary Price List
There is ribbing on the side of this that is not there on the version I have.

5.25" Floppy


The Panasonic JU-455-5 drive

"If you want an external 5.25-inch disk drive, Kaypro offers one for $295. This 360K IBM-format drive is also enclosed in a matching brushed aluminum case and is fully portable. The 5.25-inch disk drive is designed to fit on your desktop, next to the 2000, but its internal power supply lets you take it anywhere."
(Profiles, January 1986)


From the Preliminary Price List
Appears to be based on a half height drive case. I have not seen this version.

Kaypro 2000 External Battery


From an eBay listing


From Preliminary Price List

"If the 2000's four-hour battery isn't enough for you, you might consider the spare battery pack ($25). This external pack is small, measuring only 2 x 3.5 x 6 inches. With the external battery pack you'll get another four to eight hours of operation. Like the 2000's internal battery, the spare battery pack can be recharged with the standard AC adapter."
(Profiles, January 1986)

Spare Battery Pack (External) $25
Description: Small (3.5 X 2 X 6) external pack that provides an additional 4-8 hours of battery operation.
How it Works: Plugs into AC jack and sitts next to computer. Recharges with standard AC adapter (already provided with Kaypro 2000).
(Preliminary Price List)

PC card and Cable

From the Preliminary Price List

"If you have an IBM PC or compatible, Kaypro offers another option for modem-less transfer of files from the 2000 to the desktop. Kaypro's PC card and cable ($95) are designed to be plugged into the desktop PC and into the 5.25-inch port on the multi-adapter module. A software switch steers the drive to either computer, allowing you to transfer files between the 2000 and your desktop without needing to buy an additional drive."
(Profiles, January 1986)

PC Card and Cable....$95.
Description: Allows users to connect to 5.25" disk in existing PC to eliminate need to buy additional drive.

How it works: IBM card plugs into PC. Cable runs out of PC and plugs into 5.25" port on Disk Adapter module. Software switch steers drive to either computer.

Kaypro 2000 Power Supplies

Model Numbers: 81-707-1, 81-709, 81-737


Two different single source chargers
81-707-1 (115VAC to 7.3VDC)
81-709 (120VAC to 10VDC) and (10VDC to 7VDC)


This is another 81-709 two box charger. You can see that the vented
box also has a Kaypro label on it rather than the Poly Products label.


Dual source charger
81-737-1 (115VAC or 12VDC to 7.3VDC)


In this photo you can see the 12V plug which should connect to the dual source charger. (Not seen)


"Kaypro even has an optional dual input charger for less than $50 that operates from either 1 15v AC or 12v DC. This adapter replaces the adapter/recharger that came with your Kaypro 2000 and plugs into a standard 1 15v AC wall plug or the cigarette lighter in your car. If you happen to have a car with a 6- volt electrical system you don't need to buy the dual input charger. 'ibu simply go down to the nearest Radio Shack and buy a standard cigarette lighter power adapter. The only thing you have to be certain about is that the positive voltage is on the outside of the plug that connects to the back of your 2000, not the inside (they come both ways). This is probably the smartest use yet for a cigarette lighter."
(Profiles, January 1986)


From Preliminary Price List

Automobile Power Adapter $45
Description: Cigarette lighter plug with cable and regulator module to let users run off of vehicle power.
Features: Allows for extended operation in remote areas. Also charges internal battery pack.
