Subject: Have you used Concurrent DOS? Macrotech 80286/Z80H card?

Macrotech dynamic ram boards do indeed work properly with the MI-286
in otherwise CompuPro systems. Note that I am referring to the newer
design, rather than the old Max Board.
I would not be surprised if CompuPro screwed up operation with the
MI-286, but since the board is an exact replacement for the old
dual CPU board, the only thing they could have done was to make it
impossible to run Z80 code. My understanding is that as soon as the
MI-286 appeared, the nice folks at CompuPro brain-damaged SWITCH.CMD
so it would not run the Z80 instruction set.
Have you actually seen the 286/SPU-Z combination in operation in a
real system? Talk about vaproware! I had a SPU-Z on order for six
months when I cancelled same due to non-existence. It still appears
that CompuPro is the worst offender when it comes to vapor products.
I have seen enough of such goings-on to be using non-CompuPro software
(my operating system is Concurrent from Gifford) whenever possible. I
have been running CCPM for months with a MI-286 with no trouble.
