I suspect that you may be able to pick up Xerox 820-I's (a reworked BB I, very
similar to the Kaypro except that the drives are usually SS only - the second
version allows DS 5 1/4" drives, I think) for about that price. It comes with
64K of RAM, a monitor in ROM, a disk controller, CRT display circuitry, etc.
It is a CP/M machine and was heavily supported by Microsystems magazine for a
number of years - lots of tech info.
