I'm still digging. I found more 550 stuff. I think this is everything
that came with the 550. Here's a chance for you 550 owner's to get the
whole set at one shot!
Original DS-DOS box and invoice.
Original Sanyo Easywriter ver 1.3 disk
Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two
original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4
are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1
Original Sanyo disk box with all three original disk of set A, WordStar
and CalcStar and a backup copy of DS-DOS.
Two card board dummy disks used to protect the floppy drives duing shipment.
>A few weeks ago we were talking about the Sanyo 550 series and someone
mentioned one of the alternates operating systems that supported 80 track
drives in the 550. I said that was DS-DOS by Michtron.
> Today I found an old Sanyo disk package with four disks for the 550. One
of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the
other is a disk of misc utilities. The first three are original disks. In
additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that
came with the 550. If anyone wants them, trade me something I can use and
they're all your's.
I recently filled the car with these:
Apollo DOMAIN Series 3500
Domain series 3000 model 3010
HP/Apollo series 400
(2) Sun 3/60 + tape drive and tapes
Apple lisa 2
(2) apple II Ci
Mac SE/30 with radius monitor
Mac color classic
power mac 7200/90
Also available was a volker Craig terminal, and a copy
I also have "quite a pile of HP 712/715/725s in various
condition" for me to pick up when I get some space cleared.
IKEA has said that the missing piece to complete the
shelving will be delayed another 3 weeks, and my wife says
no more machines until the shelves are up!
hey do you have any ideas about using relays or some thing connected to a parallel or aerial port to control the power to an outlet, you know like a dimmer switch controlling motors ETC
if you have any thought or ideas I'd be glad to hear them.
I am getting my PDP-11/34 and my RK05 disk drives and packs tommorrow, and I have a few questions.They have have been in storage for years, and, although they have been kept dry, they are probably dusty. Can anyone tell me how to clean the drives and the disk packs before I use them?
I recently acquired a nice, rust-free, mostly-original 11/45 from
an old lisp hacker in Los Altos Hills, CA. He told me that it had been
running the last time he'd powered it up, which was in 1984 IIRC, but
sadly, something has gone awry and it won't run now, though it seems to be
close. Here's a brief summary of its status:
It was originally a five-rack system with each rack containing the
controllers for the housed peripherals. The bus was chained through to
each rack on a BC05 and terminated with an M930. I only took the
processor and the TU-10 racks, so to make troubleshooting easier, I
reduced the system to only the CPU and memory boxes (memory is a 220KB
box from Monolithic Systems that has unibus in and out). The processor
has 12 KW of core as well, so I guess I could cut the bus down a bit more
for the purpose of debugging.
Mode of failure is such:
I powered up the shortened system and the front panel lights lit
[excitement]. Then I tried to examine some memory locations via the
panel, but when I hit HALT, the RUN light stayed lit. I tried every
combination of switches I thought was appropriate, but the RUN light
wouldn't go off. (Sounds like a simple bus error, really.) Upon
realizing that something was amiss, I decabled all the power connectors
>from the logic and tested the voltages, which, surprisingly, were all
about 6%-9% above spec (and I'm not too sure that my VOM is accurate even
though it's analog). I didn't readjust the voltages, but reconnected the
power cables to the logic boards and retested the voltage levels. All
stayed about the same except for the -15VDC. It dropped to about 2V. Same
reading on both -15V regulators, by the way, and they seem to be connected
to different areas of the backplane, but I'm not sure. There seems to be
a high-pitch squeal (that sound of a laboring regulator) coming from
somewhere in the power supply cluster, but there's no smoke or crackling
sounds. I don't remember noticing the squeal with the power cables
disconnected, but that may be a subconscious hope and not a fact.
So that's my predicament. I don't have much time to mess with
this beautiful old girl, so I hope someone here can increase my repairing
Help me save this great piece of computing history. In return,
I'll at least give you an account on it if I get it to the point where
it'll run 2.9BSD or V7. I have SMD interfaces and disks, etc and
everything else I need (except a DELQA) to get it hooked up to the net.
Thank you in advance.
This has been an interesting, uh, exchange of and on many
viewpoints and I've found value in quite a bit of it, i.e. it makes
you think. But I do take exception to
>> Even business do things they don't like or wish to do.
Businesses, just like the independent people who run them, can only
do what they want to do. You do what you want to do - always. You
might hide your decisions behind the guise of "business made me do
it" or "my spouse won't let me keep the 5360 in the house" or some
such, but you made the decision, your choice is your choice.
Businesses both big and small hide behind this "we didn't want to do
it" nonsense as do individuals - but you can only do what it is you
indented to do, what you want to do, unless of course you have a
dirty bus connector or a bad memory module or a flaky CPU or faulty
You list the possible decisions, the possible outcomes of each
decision, the relative plus and minus of each variable - and then
you decide what course of action to take, You do what you want.
BTW - Does anybody know of any hobby level (cheep) GP-IB programming
tools? All I want to do is control several DVM and a counter and
function generator - minimal stuff for very basic bench automation.
Any ideals? Thanks
Does anyone have any sort of info on this thing? I just picked one up at a
garage sale for $1. The guy I bought it from had no info about it. He said
it was in the basement of his house when he bought the house...
The case is about 6" high by 15" wide. It has a 1.2 MB 5.25" floppy and a
ST-225 HD in it. It has a 286-10 CPU in it, but when "turbo" (it's software
controlled - "boost.exe" makes the computer beep then lights a green LED on
the front)is on, it clocks at 13.5 MHz (QADiagnostics). There is a 3.5" bay
that's the same height as a 5.25" floppy (anyone have a drive that'll fit in
here?), and the three LED's (green, red, green - power, HD, turbo) aren't
labeled. The cover over the HD bay is odd, too. It's frosted. Whenever
the computer's on, the green HD light can be seen through it, sort of like
the old Olivetti had.
The cards that it has are a standard MFM controller (although in a
non-standard place - it's set back About 1" from the back of the case, and
about 1" to the right of the card cage, and the ''tail" on the card's
mounting bracket goes through a hole in the motherboard)/ There's also a
standard CGA/composite video card, and an ARCnet LANcard. It has a BNC coax
connector on it.
As my luck would have it, though the "arcnet" directory was empty. All the
directories were empty but the DOS directory, and they all appear to have
hidden files, because I can't remove them.
The case is also made from a surprisingly heavy gauge of steel. All the
metal is about 1/32" thick, and it weighs about as much as a 5170 AT.
Anyone have any info on this? what it was mainly used for? Maybe a
keyboard to match? :)
Nope. No free slot. The long slot has an IBM 3363 controller in it, and
the other slot won't accept a long cart, because it hits the cooling fan.
Anyone know what the short slot's for?
Yes, I do have the reverence disk. The P70 has 4 SIMM slots.
