Ok, I just took stock of the hardware in my next room. I have a First
Class Peripherals Sider ][ hard drive (actually two) and for the first
time ever noticed that they have a Xebec label on the bottom, which I
guess means these are actually Xebec hard drives and First Class was the
name they sold hard drives under? Whatever.
Ok, so then I opened one up and noticed a Xebec PCB that is the same size
as a 5.25" drive, that contains among many other things a Z80, an 8502 and
a ROM with a Xebec label. The connector is 50 pins.
I then opened the Apple //e hood and the Xebec controller card also has 50
pins.
So I'm not familiar with the card you have at only 26 pins.
Well, sure, the drive would be MFM (or whatever the
particular Xebec
controller was intended for). I don't have the Xebec controller that came
with this particular Apple interface; I was just hoping I could use this
Apple interface with one of the spare Xebecs I have in the junk box.
Can you scan this card and the Xebec interfaces you have and post a
picture of them somewhere? I then might be able to tell you if you've got
a winning combination.
Are you
wanting to use it to hook a hard drive up to your Apple ][?
Yes. I should have been clearer; I have the Apple-to-Xebec interface, and
a couple of Xebec SASI controllers from elsewhere, and a few MFM drives.
What I need is the pinout of the 26-pin connector on the Apple-to-Xebec
interface, so I can figure out if my Xebex will connect to it. I wonder if
an Adaptec ACB4000 would work? I've got a couple of those, too. Was there a standard pinout on Apple SCSI/SASI boards?
Perhaps it's the
same as the Mac 25-pin SCSI?
If you consider Xebec to be the standard then yes. I've never seen a hard
drive controller made by any company other than Xebec.
