Subject: GODBOUT/COMPUPRO questions...
I'm looking for certain information on GODBOUT/COMPUPRO systems...
(1) is there error-correcting circuitry available? (or parity checking?)
(2) they market an 8086/8087 board, but they claim that the 8086 is restricted
to running at 5 MHz "with the 8087", vs. a 10 MHz speed without it.
(a) how come?
(b) does this mean that the simple existence of the 8087
inhibits 10 Mhz operation, regardless of whether the 8087 is actually
in use, or can the 8086 run in 10 Mhz mode while the 8087 is either
not in use or somewho disabled? can it be disabled at all?
(3) can the 8087 be accessed while running 8 bit software? For
example, if I had a fortran program wanting to do number
crunchingwhich was running on another card (e.g., their CPU Z card),
could I get at the 8087? Or is the 8087 a 16 bit job?
(4) how does the 8087 work anyway? does the cpu see it as an I/O
device, or what?
(5) can anyone recommend a good hard disk (preferably with an
integrated tape back-up) which runs well with Godbout/Compupro
controllers?
(6) I've seen a few ads specifying particlar all-Godbout/Compupro
configurations, but for my needs, none of these are just what I need.
Does anyone do custom integration by mail? if so, are they reliable,
etc...?
I will share all replies...
many thanks.
