All of SD systems S-100 stuff seems to suffer these sorts of troubles!
I have an SD SBC-200 CPU card that will not even work with SD Expand-
oram.  I can only use static memory with it.  Years ago I bought a SSM
EPROM blaster to run with the SD card.  Hah.....fat chance!  All it was
good for was the 4 on-board EPROM sockets!  (i.e. an expensive, small
EPROM card!)  The programmer never worked because it tried to use SD's
pSYNC (or was it sMEMR...forgotten now), and SD's rendition of S-100 was
never standard.
