So, i got a 8700 computer, a QUASH and another powersupply off ebay recently. im very happy.
but heres the problem... whoever soldereed this, for one, is very sloppy and for two, hacked it up in a weird way. specificaly on the powersupply. the schematics weren't followed, and no notes were left. so i need to fix everythign on there before i power it up to make sure its going to work properly.
the 8700 i got is the lowest you can get basicaly. no cassette interface.. no muse1 eprom just the monitor. so its NEAR useless, haha. ill have to try and find a way to get the cassette interface eprom... maybe someone out there at some paia mailing list has one and can also copy them, high hopes. but im going to try.
i've already tried with paia, and although they are EXTREMELY helpful, they didn't have the eproms or any programs, the 8700 has been out of production since the early-mid 80s.
the guy i baught it off said he used the modules to sequence his moog... and i cant figure out how he did that, since theres no connections to the 8700 computer at all except power!... ho hum....
so i have alot of work ahead of me. i also need to decide if im going to make a new case for the computer or put it into my suitcase modular... not too sure yet.
sorry, thaught id give a little technical rant.

Do you have the "Friendly Stories from PAIA" articles? It's goes into more detail about connecting the 8700, 8780 D/A, and the QuASH, including pinouts. I can't remember where I downloaded it, so I'll post a copy on my site for a while.
From what I can tell, the standard connections are from J1 on the 8700. The 8 digital-out pins (on the right of J1 if the cutout are on top) go to the D/A, while the other pins are either blank or for stuff like the cassette interface, gnd, etc. I guess the guy just hooked those pins up to whatever DAC he had built for the Moog. He would have written his own expo-out software instead of using the PAIA stuff, which explains the no-tape-connection.
The pins in J7 are connected to the QuASH to select channels.
I've got a 8781 and QuASH but not 8700. I almost bid on that one a few weeks ago--probably the one you got? Forgot to turn on my sniper.

thanks otter. got the file.
yeah, i got the one a few weeks ago.
i've been asking scott lee from paia some questions and he said the quash COULD be hooked up straight to the computer, but it would just be 5V, and im sure that woudl mean just gate, no CV right? i am almost COMPLETELY clueless when it comes to computers.

Scott Lee said: "There aren't any PAiA applications involving only a Quash and the 8700, but if you want to experiment, you could select the active channel of the Quash with address lines from the 8700 and do one to four, or four to one, routing of analog signals in the range of 0-5v. The D/A line on the quash is the one that goes out to the four cv outputs and the M line is the one that is from the four Modulation inputs. The F1 line is a single addressable bit normally representing a gate trigger and the F2 line is a single addressable bit that opens or closes an electronic switch section in parallel with the Glide potentiometers (glide of the pitch cv on/off)."
