Anyone know how easy it is to adapt one of these
to work with an IBM
PC compatible class machine? I have one sitting around here somewhere
and if I recall correctly the drive is a bog std. YE-DATA DS 8" drive
so it should be just a matter of making sure the cabling is ok.
If it is a 50 pin edge connector, then it is LIKELY that it follows
the Shugart 800/850 pinout.? BUT, it is still a good idea to find and
check the pinout of the specific model drive, since some added
additional signals and/or repurposed pins for other purposes.
And, check the drive specific pinout for power connections!
5.25" drives had a standardized power connection.
8" drives do NOT have standardized power connections.? Not all used
the same power nor connector nor pinout as Shugart.? In addition to
5VDC, you may need 24V or 12V, and maybe even -5VDC, or even AC.
If it IS SA800/850, then FPADAP,
http://www.dbit.com/fdadap.html
is an easy way to handle the cabling.
The website say that they have 5 in stock,
so order immediately if you need it!
If you are reading ONLY, and not writing to the drive, then you do not
need the TG43 signal and circuitry, in which case it is trivial to
make your own cable.? The majority of the 5.25" (SA400) signals are
even in the same order, so you can start with a 34 pin flat cable,
peel out a small handful of the wires, and crimp them in a 50 pin IDC
edge connector.
YMMV.
