I am looking for someone who can read an ICL EDS8 disk pack. I am told that it
would have been used in an ICT type 2802/2 drive on an ICL 1905E, but that it
is also compatible with an IBM 2311 disk drive and that it uses a mechanical
assembly based on a CDC 9450. Given the mention of the 2311

I'M slowly going through my library and should be done in a few months. I
should have an extra copy somewhere, but it will probably be a while.
I've already decided to sell off all VAX, massbus, and most qbus.
Do you want a hard copy when I find it?

Although I can find the RK11D users manual on the web there doesn't appear
to be print set (schematics) out there. Does this exist somewhere under a
non-obvious name?
Thanks,
Marc Howard
weird I would have missed that, it's the most common unibus disk interface
there is

I'll have it up on bitsavers by noon PDT

The RK11-D controller maintenance manual is on Bitsavers at:

The electronics isn't the problem. Getting a poorly stored electromechanical
device to not
turn your or any other pack into a pile of aluminum shavings is the problem.

I have a crashed CDC 883-91 disk pack. Looks clean, stored properly.

I have a pair of 8032 Pets. One of them has a short on the motherboard
that causes the fuse to blow whenever it's turned on - looks like its
previous owner tried to repair it as the power connector is a bit burned
and a new, non-pet power connector has been added. Likely one of the

Hi, I seem to vaguely recall that there was a poke to enable 40 column
mode on the 8032, anyone know what it is? Couldn't find it in the Pet FAQ.
Doe this command in basic cause your 8032 into thinking it's a VIC 20":

I did not actually try this, does it work?

Alan,
Thanks. I'll wait a bit to see if Al can locate the schematics and put
them on bitsavers. I guess they're either pretty reliable or everyone that
has one has a real print set.
I got one on ePay a few weeks ago. I still have to wait to get time to
install new heads (shudder!) on a spare R
I am trying to LTSpice simulate a DEC H-724 power supply from a PDP-12. It
includes a Motorola SDA7 dual transistor. I can find any information on
this part. Anyone have any info?

Commodore didn't use any capacitive keyboards on 6502-based computers.
That would have taken extra electronics and cost more.
I don't know whether any of the Amiga keyboards were capacitive, but I
suspect not.
