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).

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.

Groan...to have complete system needs one rack... that pretty large
by my space standards. 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.

Don't use an "around the house" cloth. 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. I wish I had a box.

The astonishing thing was that the newsperson managed to say "Authorities
*suspect* alcohol was involved" with a straight face.
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!

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.

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...

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.

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 have a Corona Data System PPC 22 portable computer about the size of a
small suitcase with a built-in 9" monitor [like an Osborn with a slightly
larger screen]. If you folks would like to have it, I will send it. I may
be able to dredge up an owner's guide or the like, if you think it would be
worth the effort.
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. If you wish, I'll grub around for the program
floppies for Multimate.
Let me know at your convenience what to send and where. My wife will be so
thrilled!
