I just recently purchased an old Toshiba T5200/100 Laptop at a thrift
store. One of the cards installed in it was an old 8-bit device of
some sort.
First of all, here are pictures of the card in question.

Can anyone here help me identify what this card is, and more
importantly, where I can download MS-DOS drivers for it?
It is from Maynard Electronics, 1988. The large socketed chip says:
WD33C93A-PL
00-08 9031
069660200102
PROTO
Other markings state: Type II Controller, and Rev. -5
The FCC ID number is D8I6I2 60201.
Just taking a wild guess, I suspect that this is some sort of SCSI
Controller. However, I could not find it in the TH99 archives. The
only match for Maynard on Driverguide is for a 16-Bit SCSI driver from
Seagate. Also, I could not find any info on Seagate's site either.
So, anyone here have any info on this card and possibly know where to
get drivers for it?

I haven't seen one of those in years... i'm pretty sure it's a controller
card for a maynstream external tape drive (least the last one I saw was
hooked up to a maynard tape drive)

I agree. I have similar cards made by 'mountain
computer' for tape drivers, which use NCR 53C94. One
good point of those cards is that you can talk to the
SCSI chip directly thus they can be used as a
developement card of those chips. I used mine to
control real SCSI drives from within simh.

I missed the first original post of this, but it's definately a SCSI control
chip. iin fact I have one of these chips on a card somewhere.
it is also used in amiga's etc for their scsi I/F,. I would assume that if
you are using it under a windows OS, it should pick it up. I know it used to
with mine. it's been a while since i've used it tho.

Just taking a wild guess, I suspect that this is some sort of SCSI
Controller. However, I could not find it in the TH99 archives. The
I think the 33C93 is a SCSI interface chip (I've seen it in other
machines), so your guess is likely to be correct. But it may have come
with some particular device (CD-ROM, tape streamer, etc) and there may
never have been 'standard' MS-DOS drivers for that card.

I think that they were rolled into something else later.
all those were makers of proprietary interfaced tape backup systems, or
such, which either had parallel port, floppy extension or replacement
interfaces,
or scsi interfaces.
none had documented interfades, though if you can find on the unit where
the scsi chip's registers appear, and then trace back from the dma lines
on the ISA edge card which dma's are connected, you can probably write
or adapter one if one exits for the wdc 33C93. most likely place for
inspiration
would be in early copies of Linux, for which people may have written
drivers.
those drivers are usually good sources of info on the chips, as well
as code that can be used if you are doing GPL-able or for your own
amusement work.
