The first implementation was done for the 7090 by McCarthy (hence CAR and
CDR --- Contents of Address Register and Contents of Decrement Register).
If you want to see a tiny implementation then look for the PDP-1
implementation done by L Peter Deutsch. There's a book chapter and then I

Or was it an IBM 704?

I thought I'd mention, do use caution when fixing pulse generators. The output

Hi
I thought I'd mention that when troubleshooting a computer, if you can't
takeover the execution of the processor, such as a diagnostic ROM, a pulse
generator can be a useful tool. For most all TTL, except some bus drivers, one
can use a pulse generator to override a 1 value to inject a signa
Much to my surprise, there are CAMAC Crates and memory cards on E-Bay. How you
would use this I don't know. When I worked at NERC we used them for many many
tasks.
We had a Honeywell L66 running GCOS3. We used these to emulate Honeywell
RNP707s. These were like 3780's so remote work terminals, p
