- Apr 12, 2006Nope, that's EAI Electronics Associates Incorporared.
They did analog computers across the street from Concurrent.
I used to repair their Vax and PDP11/45 when I was at DEC.
They later moved from the PDP11 to control the analog stuff in their later hybrids to Concurrent/PE stuff and also some big number crunching stuff from
Gould's SEL fokls.
I later worked for Concurrent on their stuff (their Unix was interesting).
The Masscomp RTU line was brought in in 1987 with a merger with Masscomp.
Masscomp was full of old DEC RSX guys who put the real-time EMT's into Unix.

Our company moved a lotof their systems to run our network monitoring software (yeah, companies dedicatedminicomputers to monitoring network traffic). And yes, they were all 32 bit machineswith a common operating system.Their OS was called OS/32; I joked with my friends at Microsoft as to why they didn'thave OS/2 ready, yet I was using a "much better" OS/32 at work.PE machines were big number crunchers, and the OS stank for multi-user applications.I forget what the multi-user hack was called, but the base OS only supported a singleuser, and you'd load this horrible hack to allow multiple sessions. FORTRAN was theprogramming language, but they eventually added a bugger C compiler. We ran aZ80 cross assembler for our development (Dave... what was the assembler? It wasthe same one you guys were using at HDS at the time).When I visited the VLA (Very Large Array) in New Mexico the first time and got thetour, their data processing center was filled with big PE machines. I got talking to oneof the guys there who said PE was the only viable way to crunch all the data comingin from all the dishes in a timely manner. Ugh... it was awful for code development, butran heavy math stuff really well.At one point, I ran our big MPU system... Multiple Processing Units. We had 10 bigcabinets. One contained all the 300mb hard drives and tape deck (9 track). One hadthe main CPU and I/O control unit. The other 8 big chassis held one additional CPUeach. Very big, very impressive.PE was based in NJ, so we got excellent support from them. Every now and then I lookfor old PE stuff on eBay, but I guess it's either all stored in old storage areas withcobwebs or long-tossed into landfills. This is an interesting find, and deserves someattention because those machines were very common in the 70s/80s but are very hardto find now.Bob----- Original Message -----From: Evan KoblentzSent: Tuesday, April 11, 2006 9:44 PMSubject: [midatlanticretro] Big rescue opportunity...A guy in the NJARC works for a computer consulting company in Eatontown
(right next to Wall Township, where InfoAge is)... He's got a whole
motherload of Interdata minicomputers, peripherals, and random other stuff,
and he says lots of it still works. I'm meeting him tomorrow at 3:00 at his
office to check it out. He said much of it came from the NJ and NY lottery
commissions and other places. He's also got documentation for much of it
and contacts with the company founders. Interdata has a long history,
explained at http://www.ccur.com/corp_companyhistory.asp?h=1 ... They claim
to be the first company other than DEC to run UNIX on 32-bit minicomputers.
They also did lots of work with Bell Labs, which makes sense -- it's good
for our museum to have things from a very local company.Pioneer Purveyor of Personal Processing Power
