I am running SVAT on a Chop-Suey model clone. This machine has never had
compatibility problems. My suspicion is that the error on your Kaypro does
not appear consistently. I get this too and I suspect it is a bug in the
machine code fragment that patches the CtlAltDel entry point to perform the
full memory test instead of the "quick" boot sequence. If there was a
delayed interrupt from the hard disk when the back-patching was supposed to
occur, I can see where the problem would lie.
On another note, I can't see how you can do real work with all three
portions existing on one 20Mb partition. It is a saving grace if you can
get the second hard disk in your system. I am using the second drive to
hold the USENET files (20Mb/week).
