You should be able to replicate it. Will send you in separate email.

I’m restoring a SWTPC 6800 that includes the Percom LFD-400 floppy controller.
This controller goes on the SS-50 bus instead of the SS-30 bus where the SWTPC
controllers installed. The standard Percom MiniDOS PROM is installed, and the
other two PROM sockets have a third party extension called
Bitsavers has a schematic of the ANSI interface version of the Priam
3450/7050 eight-inch hard drives, but does anyone happen to have the
schematics of the "normal" version (Priam interface, as opposed to SMD or
ANSI)?

there are a few obscure ones there. I was looking for

I'm having some trouble getting Frotz 2.50 ported to TOPS20. Version 2.32
with dumb interface compiles fine under KCC. With 2.50, there are several
preprocessor lines that include parentheses. For instance:

typedef unsigned int uint32;

Have you searched for them on the NXP web site?
I found the RF ones here:

Wow. I have a PDP-8/I to connect it to, but I seriously doubt I could
Wow, a TU55 + TC01. Were they once a part of a PDP-12?

The description is not showing at all - no text.
This is one of those Ebay bugs that has been around for months, but
they do not fix. I have reported it several times - you should too.

Hi John,
You may already be aware of it and visited if you've ever been to Chicago,
but, the Museum of Science and Industry is well worth a visit if you don't
find anything more computing oriented that's more interesting. You can
check out their current exhibits and search for computing exhibits
Made the mistake of not defining that path early on so mostly personal/home
computing. But anything I find interesting or historically interesting
often finds a way home. I think my largest sets are Commodore and
Tandy/radio shack.
I see a store called freegeek and "Chicago computer club" which
I'll make another effort to reach Lars.
/P
