Re: drive info
Keith,
I should send this message to 'Bob Safranek' at 'ucbvax!pue-ee!rjs'
(if I only knew how to get MM to do it). This notice on the CPM bboard was
info on 'ollivetti' drives. Could you foreward this to him. Thanks in advance.
I purchased a 'new' 8" SD floppy drive (made by CDC) for $175 from a company
called 'Meshna' '(617) 595-2275'. The drive works great but there is a catch.
The motor for the drive requires 220v @50 HZ . The fix is: (1) they send you
a step up transformer 115 to 230 which works just fine. (2) the pulley
on the drive is reversable one side is 50HZ and the other is 60HZ. So all
you do is flip it arround. The last catch is that the 50 pin (io) edge
connector is different from the Sugart. I solved this by hacking the traces
on the drive (once I knew it worked) so that the signals now go to the 'right'
place on the 50 pin io connector.
The DC voltages of the drive are 24v@1.3A and 5v@.8A. Also if you
find a problem (before you hack the traces on the drive) you can send the
pc board on the drive back to Meshna and they will send you a new one.
The controler I have is a Versa Floppy I (old but good).
If you dont mind the hacking to get it working you can't match the
price $175.
Good luck to all,
