and was wondering how this system differs from the Kaypro II?
Will CP/M and Boot system disks for the Kaypro II work on the Kaypro 2?
(and vice versa)
Looking at the back it looks like it might be a "Kaypro 2X".
I can't help answer your compatibility question but here's some
information that might help.
Slightly edited quotes from old-computers.com : "The Kaypro 2x was one
of the last models Kaypro produced. Size and appearence were the same as
the first Kaypro II, but Internal hardware was inspired by the Kaypro
10. It came with a 4 MHz Z80A processor, dual slimline 400 KB floppy
drives, a built-in 300 baud modem, two serial ports and a full set of
Micropro software (WordStar, CalcStar, DataStar)."
History of the Keypro II/2 names.
"Kaypro II released in 1982, no graphic features, it can display 80 x 24
characters. There are two single-sided / double-density full-heigth
5.25'' disk-drives (190k each).
In 1984 a new Kaypro 2 (refered as Kaypro 2'84) is introduced. It has
two SS/DD half-height floppy drives, a Z-80A running at 4.0 MHz, 2
serial ports and rudimentary graphics (through graphic characters).
The same year, the Kaypro 2X is released. Very similar to a Kaypro 2'84
but with DS/DD half-height drives.
Still in 1984, in order to be compatible with IBM software, a special
version was marketed with an Intel 8088 CPU instead of the Z80A. It was
called the Kaypro II Plus 88!
In 1985 another Kaypro 2 refered as "New 2" is sold. It is basically an
old 2X motherboard, with one or two DS/DD floppy drives, but no 300 baud
modem previously found on the 2X. It comes with just CP/M and Wordstar
And to spice up a bit things, Kaypro decides to rename its Kaypro 4'84
as Kaypro 2X (sometimes also known as 2X MTC), thus dropping the
previous 2X model!"
So, the "Keypro 2" on ebay could be a Keypro 2'84, a Keypro 2X, a "New
2" or a the later Kaypro 4'84 depending on what's in the box.
It gets a little confusing but with Kaypro's there are two major factors:
Boot ROM number and whether is Single Sided or Double Sided drives.
At the end if the Kaypro they finally developed a "Universal ROM" where any
changes were transparent since all entry points were fixed.
A Kaypro II is totally different than a Kaypro 2. The earlier computers
(often referred to as 83's) had one type of motherboard and the later
computers (the 84's) had another. The boot ROM from an 83 could not work in
an 84 and vice versa.
As long as you kept the ROM with its corresponding boot disk you are OK. I
am not sure how many different versions there were, Don Maslin knew.
I have several new items including boot disk images to post on my website,
if anyone has boot disks (Kaypro or not) that I don't have please contact me
