I.B.Computers of Portland are selling a 5 1/4 floppy drive for the ST. I bought
one of these, and couldn't get it to work. Sent it back to them to fix, and it
still didn't work when I got it back. Then I saw a network note to the effect
that the side select signals and drive select signals must be buffered.(Thanks
to Myron Drapal.) I installed a 74LS241 and the drive started to work properly.
IB Computers don't seem inclined to notify their customers of this problem, e
en though I wrote them a detailled letter, so anyone considering a purchase of
this drive should bear this in mind. Be prepared to modify the drive.
If you need a detailled description of the mod, send me mail.

I work at IB Computers and them check their repair records and even though they keep records of all IB Drive repairs, they have no record of recieving or repairing your drive. Did you send the drive back through the dealer you bought the drive from or did you send it back under a different name? Even though I don't have anything to do with the manufacturing of the IB Drive (other than working for the same company) I'm interested in getting the mod info you describe. If this fix really works, I'd like to see them add the info with the drives. Or if it's a mod to the drive itself, to implement it in all future production. The strange thing is that for the number of computers I've seen the IB Drives hooked up to, I haven't seen one that needed a mod to the hardware. But I guess there are a rare few. Peter- If you can Snail Mail me a copy of the mods, I'd appreciate it! Just mark it Attn: Russ. Russell Schwartz ..!reed!percival!russ I.B.
