Some guy on eBay is selling a ton of QBUS boards, cheap:
http://www.ebay.com/sch/computer_surpluscheap/m.html
Includes deals such as 11/23 CPU's _with_ KTF11 and KEF11 for $30, 11/73 CPU's
for $50, etc, etc.
Anyone recognize those Motorola memory cards? Do we have documentatio for
them?
I have a Shugart 800-8 with a media centering problem. I know it is
definitely that and not something else (say, electronics, TRK00
position, etc.), because I can see the "wobble" in the signal coming
from the heads on a 'scope. Depending on how I load the floppy, the
attenuation can be from noth

Not enough logic on there to do that. It would have been a parallel interface

Thanks for the tip! He's got some nice stuff and the prices are not awful
although I'm pretty well stocked on what's he's mostly selling; 11/23 CPUs;
MOS memories and SLUs... I was hoping for RX01 or RX02 interface for $20,
heh. There's definitely some good opportunities here if someone wants to

Hi Holm,
If you don't find anyone else I'd be willing to do so for you.

Hello Seth,
Thanks for the update.

It could be an indication of pot metal failure.
I had one drive that the spindle from the driven side was clearly

What happens is that the metal has oxidation at grain boundaries.
It is said that it is caused by small amounts of contaminating
metals
