Since it's kind of empty in this corner of the forum, I thought I would put this up. I just bought it, sight unseen. 3C (Computer Control Company) Card rack, vintage 1964. 3C was bought by Honeywell. This card rack is called an S-Bloc, because it uses S-Pac modules. I was told it was from a DDP-24, although I'm not sure of the subtle differences between the DDP-24, DDP-114 and the DDP-224.
These were also sold individually, so you could build your own frankenstein monster.

3C S-Pac modules made up of discrete components. Some are NAND, Flip-flops, Logic...

Al Kossow's got some stuff on the S-PAC stuff on bitsavers (http://bitsavers.informatik.uni-stuttgart.de/pdf/honeywell/modules/130071175D_S-PAC_Supplement_Apr68.pdf). Old PNP germanium transistors, yet.

It would be very cool to find some of those S-PAC stick-on symbols.

OMG! Do you still have this? Unless someone faked the name, this is part or the computer on which Max Mathews wrote GROOVE and other music software. I worked with that computer 1973-79. I have the control panel, which I see you are missing. You can see it here, on my web page for the recent album of music I did using GROOVE:

This was a historic machine for the development of computers in music and art.

It is not very often you get the woman who worked with this beautiful machine responding.

I can verify that this is a critical piece of music history. Laurie responding verifies this. This is a really critical find. In fact I would argue (though Laurie may not agree with me) this belongs in the Smithsonian, or another museum of importance. This is a huge piece of music history. The signature is proof. It had a huge part in evolving computer music. The history of this is all over the place. This is no normal vintage machine.

This is a critical find. Please get in touch with Laurie at the very least.

Hi Folks. Maybe the Bob Moog Foundation would be interested in this for the Moogseum? I could ask if you think it appropriate.

I was just poking around google and came across this thread. I have the Rp-31 8 amp power supply for the S-Bloc.
