Hi, I talked to parasoft and they agreed to freely release express for non-commercial use. Unfortunately, they lost the binaries a long time ago. So, does anyone have a copy for the following architectures: Transputers Parsytec Meiko Once I get it, I'll post a copy on my webpage at http://members.xoom.com/transputer BTW, if you dont know what express is, it is a communication library for parallel computers (similar to MPI & PVM) and it supports a wide range of computers. A lot of interesting software was ported to express at one time (but nowadays, everything is MPI & PVM).

PDP 11/70s For Sale

by danburrows＠mindspring.com

Sounds like a few people need to do a subfeed like I did for the test beds here. 100A dedicated panel mounted directly behind the 9 bay 6 foot tall rack. That panel will one day be fed from the 10KVA UPS I just have to get new batteries for. This sub feed is off a 200A feed that is for my office only.

But my eyes lits up on that 70 lights... whew! Which series is most compact (sized for desktop or tower style) pdp or vax and only needs one wall power cord to run whole thing (including storage built in). Current draws snipped. Even I did manage to bull through my parents and did gotten that 11/70, breakers will trip every time I power just the cpu itself up. I throw out flames at my parents every time they accidently tripped the breaker with that ac unit making my computer go out, all plugs in my bedroom and few in living room including my alarm clock and shop computer go dead. I hated this apt even it's located in nice location, nice people. But I do have 2 negatives about this apt, floor is very bouncy for a uneven cement floor (too thin?) and too few breakers on too many circuits attached. Landlord turned down the request to put insolated circuit and a breaker just for ac even we did pay the electrican ourselves. Lots of space in that breaker box, 5 spaces left actually. > Well worth it, though...upwards of seventy LEDs on that front panel, all > merrily blinking away...fast machine, too. An excellent design.

The right tool for the job are laboratory "Kimwipes". They are non-woven, truely lint-free wipes for labware. I know of FE's who have cleaned RK packs with a squeeze bottle of isopropyl (95%+ IIRC, not 70%) and Kimwipes. Besides a chem lab, I don't know where to get them, but they are what you want.

7900A drive: 1 , Me - 0

by jlwest＠tseinc.com

Here's another installment in the ongoing HP7900A drive saga (yes, it's a plea for advice and/or sympathy <grin>) Installed new (refurbed) lower heads and new lower platter. Recleaned inside of drive. Powered up, put in new removable cartridge. Hit load switch and waited 25 seconds, then hit unload. Did this a few times (the blowers and drive spins up, but the heads don't load for 30 seconds - did this to get any remaining particles out). Removed cartridge, powered down, removed covers and reinspected everything inside. All looked well (including heads, which were fully retracted). So, this time I powered up and hit load. Waited 30 seconds, heard the heads move out to cylinder 0. Ran drive like this for about 3 minutes, no problem. Hit unload. When I removed the removable cartridge, I noticed the heads weren't quite retracted all the way. They were well off the media, but not all the way back home (the heads weren't touching each other, but they were close). Manually pushed the heads back, rechecked everything I could find. Repowered up the drive, after 30 seconds the heads loaded. Drive ready lite comes on and ran for about 15 minutes. No HDI sounds at all. I was elated. Hit unload, and after about 20 seconds heard very soft HDI. This time I left the cartridge in, powered everything off, removed the covers, and this time the heads weren't retracted at all. They were sitting right on the media. Strange thing is, there's no marks on the media, the lower heads I replaced look pristine, and the upper heads have only the very slightest indication of oxide. Gee - perhaps this is why the drive originally had a head crash before I got it? I've been through the "theory of operation" text and flowcharts. Several things confuse me. First, I thought that hitting the unload switch was pretty much of an immediate voice coil retraction - I didn't think this went through all the normal logic circuits. Second, the coil can't be completely shot I wouldn't think, because as I understand it the drive ready light won't even come on unless the positioner moves out to cyl 0 correctly. Before I replaced the heads and media, I don't THINK I had this problem, I think I would have noticed if the heads weren't retracting before. But, I can't imagine that anything I did related to replacing the lower head set and the lower platter would have anything to do with this. Input anyone????? TIA! Jay West

PDP 11/70's for sale

by mmcfadden＠cmh.edu

All of the PDP 11/70's I have seen seemed to sprawl to fit all of the available space with a few peripherals on the floor or on a cart nearby. The PDP 11/70 that I used the most between 1977 to 1982 was configured in 4 bays and a RP04. Bay 1 CPU with 2 8" floppy drives above Bay 2 expansion chassis with 2 DZ11 terminal multiplexors and TU58 cassette tape Bay 3 4 RK05 drives Bay 4 TU10 tape drive The RP04 sat next to the CPU. For RP04 backups we carried the disk packs to another building and made a copy. Initially the system disk was one of the RK05 drives. Each users programs were on another RK05 and our data was swapped in and out on the two remaining RK05's. When we first received the RP04 we configured it to look like multiple RK05 drives to fit our software and database scheme. We considered the 11/70 a "hot machine" especially after the PDP 11/35 we had originally. It was a race horse and had 320 K words of memory!!! We had 6 programmers, 1 operator, 2 Versatec plotters and a Printronix P300 on the system. Each user had their own VT52!!!! Later we had several VT100's. Compiles took less than 1 minute. OH for the glory days. We collected microbiology data from PDP 11/05's and PDP 11/04's on cassette tape until we started using the 8" floppies. Each PDP 11/05 or 11/04 had a VT52 with an internal wet paper printer.

IBM 3270 PC

by mallison＠konnections.com

hat's interesting because mine has a 10MB drive buit in. I didn't think they came without HDs because they needed the terminal software, etc... -----Original Message----- From: David Williams <dlw(a)trailingedge.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Friday, September 24, 1999 8:42 AM Subject: Re: IBM 3270 PC I think I've seen the monitors before too. I may have seen the keyboard once long ago. But I already have an IBM PC which I use to play around with CP/M-86 so wasn't sure if I wanted to keep this. Of course the PC is a PC and not an XT. It doesn't have the hard drive on it so maybe I'll use this one as a CP/M-86 machine now. On 24 Sep 99, at 8:33, Mike Allison wrote: > I sometimes see the monitors. They're VERY obvious.

Corona Data System double floppy IBM Compatible PC (fwd)

The Corona Data Systems portable is a bit historic in that they copied the IBM PC BIOS without license from IBM and got sued out of existence.

I haven't had the heart to discard it; it had the most readable display I have ever had for word processing. I used Multimate, of course, to go with the Wang system at work.
