Re: 2650 S100 machine
I obtained this machine from it's designer, and it is definitely NOT a joke!
The particular 2650 processor card in this machine was a prototype for a
card which was published in an electronics magazine here. I have quite a
few software tapes (yes, cassette tapes, as this ran CP/M from a cassette
(AFAIK)) and can confirm that it was running CP/M via an 8080 emulator
written in 2650.
Machine looks great, and if there's any requests, I'll improve the pictures
and do close-ups. Totally homebrew in that every single card was made by
the owner - no commercial stuff at all. Heck, the power supply is even
homebrew :)
Cheers

I guess prototype 2650 S100 machines / cards
qualify? There
must be a lot
of homebrew "single instance" machines
lying around. Here's one I'm
particularly fond of...
http://www.comcen.com.au/~adavie/weird/s100.html
This machine ran CP/M on a 2650 using a software 8080 emulator
written in
2650. Slowly!
Just tell me this is a joke ... not only a 2650 _somwhere_, but
rather a real S100 system - Geee I can't get it ... THATS great
I think this is from now on my personal favorite for the most
unusual homebrew uP system of all times. Thats just fantastic!
(BTW, it's maybe not very visible, but I had some relations
to the 2650 in the past ... my first uP :)
Of course this is a _slow_slow_slow_ thing when emulating a
8080 - I guess it runns like a 100 kHz 8080 :))
I know, the idea is not new, but I still think it's worth to do:
What about a list of all systems 'known to exist' i.e. a list
of all machines that are 'alive'. THe question about singularity
comes up every half year, so this list could help. If there is
some interest, I will volunteere to compile this list.
Gruss
