I used a System'34 when I worked for IBM in 1985-86. It was old then -
late '70s?. I seem to remember about 224K of RAM, possibly 256MB of
hard disk.
There were a number of posts on this subject on this list in late
September - start with the thread on IBM 5120 on 18th.
I would be very sad to see such a system vanish - I have a certain
affection for it after discovering that I - the newest student - knew
more about system/34s than anyone else in the building (this wasn't much
- the building housed two marketing units).
If you - or someone - do manage to acquire this sys/34, I may have some
spare copies of one or two pocket quick reference guides I could send
you. I'm pretty sure I've got OCL pocket reference (about 1/2 inch
thick) and I may have the Assembler pocket reference.
Finally, where is this machine? If it is in England or Wales I might
consider acquiring it myself...
Philip.
Thanks for the tips! I had found something that I suspected was
an optical sensor, but wasn't too sure. And cleaning it out as best
I could didn't change anything. Of course, I couldn't get at the
thing very well. And, as Tony pointed out, common-sense wiring of
the thing would mean the problem couldn't have been just a dirty
lens.
The good news is that I have a working drive to compare against,
so tracing the problem shouldn't be that hard. Maybe this weekend...

You'd think so. The last time I tried fixing these drives (a couple
years ago) I was trying to work backwards from the select LED. Had
big problems tracing the circuit because the traces go under chips,
and often turn corners under there, so you can't see which ones go
where. And I was paranoid about using a continuity-checker for fear
of putting voltage someplace where it could do damage. (Was that
being excessive?)
On the other hand, it should be trivial to measure voltage of the Trk00
signal at the connector, and see if it was getting that far. Divide
and conquer - the first secret of debugging.

I spoke with a fellow who has a print set for the board, he indicated that
there are no diodes on the board at all. There are, however, quite a few
bypass caps shown on the schematic. My glass devices are all in parallel,
each associated to a particular, IC, and are grounded on the other lead.
I will have to remove an intact one to check resistance and determine what
they are.
Thanks for the reply,

Sorry, folks. I've been asking around about what a System/74 is. I looked,
and it's really a System/34. Could someone tell me what they were for, how
much they were sold for, what year they are, what they're worth now, etc,etc.
Thanks.
By the way, I may be able to get my hands on those unidentified IBM network
cards, maybe I can get a couple or two. I'll also look if I can find a hub
for them. There are also some PS/2s (not for sale), which used to be attached
to the network, which is now ethernet. The PS/2s, however, have a weird cable
that looks like the monitor power cable. It has a box on the end, about 1" X
1", that has a ton of electrodes. What is that?
OK, so they weren't called that early on. But still, that's what
they're called now. What I really want is something small, but
powerful. (This classic is going to get USED) I have two schedule
programs; MS Schedule+ and a program called Sidekick 2.0, for DOS, made
in the early 90's. Compatibility would help. I also want something
that's not to hard to find, and I can get for less than a Palm Pilot. (A
lot less, if possible.)
Thanks for all of your assistance,

Further investigation shows that my estimate of 1983 was incorrect. The
design of the model 320 dates from around 1985, and mine appears to have
been built early in 1988.

Hi All:
I am working on a sick M8310 board from a PDP-8/f.
I've found and removed a broken diode. It has a glass housing and
resembles a germanium variety that I used to see often in my early days.
The board has over a dozen diodes, all are the same. The diodes are not
numbered but have three coloured bands: Orange, Black, Brown.
Not having a suitable reference, any '8 owners out there that can tell me
what kind of diode I should replace the broken one with?
Thanks,
Kevin

I spent a most enjoyable day today writing an emulator for the varian
620/i processor. I have a few questions about the handling of the
overflow flag if anyone can help.
Also does anyone have any software for the beastie?
What happend to the Varian computer division?

I think the best way to do this is to make disk images. I know the Mac can
do this with Mac disks, and I'm sure the PC can too, but I've not found
(i.e., not looked for) the software to do it. Can someone recommend a PC
program to read 5.25" (and 3.5"?) diskettes and make images of them?
This, I think, is where syquest drives (and similar) come in *very* handy.
You can store the images on a removeable disk and not bother taking up fixed
disk space for them.

I can plug in everything else, and all I get is a relay click.
I found the easy way to play with these plugs is to set the BA11
upside-down on the table, and unmount the PSU so I can get access.
What is J5 for and what voltages are supposed to be there?
I have an oscope here, and I may be able to dig out a VOM...
It's obvious I switched wires or something in the line power module.
Visual inspection shows nothing obviously wrong...

No standard Macintosh can use the Apple IIgs RGB monitor. The video
port on the Mac provides a signal with a horizontal scan rate of
about 35kHz -- this figure is for the Mac II; newer Macs may be
higher. The Apple IIgs monitor and system video port use a scan rate
of about 15.75kHz. Both IIgs and Mac systems provide analog signals.

The LC and IIsi were the first (non compact) Macs to have video on
the main board and folks were pleased to note that, using the right
cable, it was possible to hook up to a standard grotty PC VGA
display. The pinouts are available in Apple's Tech Info library.

Lots of older computers will work with the early Multisync monitors.
I've used the same Multisync on my IIgs and on a PC. I've run out of
D-connectors temporarily; when I've been shopping I'll sort out the
cables to attach the monitor to my (digital output) Apple III and to
an LC-series Mac.

Okay, I narrowed it down some:
I unplugged everything except J3, the power switch.
I plugged in that edge connector to the line module, OK.
Power on: loud click, but the breakers held.
Next, I plugged in J5.
Power on: *CRACK!* Both breakers go.
The breaker on the powerstrip is holding though.
What is P5 for?
Just an FYI...

That was 64bits of internal storage and that is different from a 64bit

There are otehr 64bit cpus, some are in games and other embedded systems.
However the number of systems for general purpose computing using 64 bit
cpus are however few.

Found the following on comp.sys.ibm.pc.rt
Anybody near him wanna rescue these machines.
I acquired one about a month ago here in Indiana, along
with a fairly complete set of books and disks. Mine has
two ESDI drives (300mb & 110mb) and loaded with
AIX 2.2. It's a tower case about 24" x 24" x 9".
If I remember the front panel says System 135.

Message-id: <645pd8$cbc$1(a)news3.texas.net>
I recently acquired this whole bunch, with the intention of getting
at least a couple of them reloaded and working; however, I've now
got plans to move soon, and cant afford to move these machines. I'd
like to see them go to a good home; so they're free to the first
person to come pick them up.
System Configurations: (6 systems)
EAP processors (16mb RAM each)
dual ESDI hard drives (unknown size)
SIIG ISA-bus I/O cards
Graphic cards with 6153 mono monitors
Ethernet (AUI / 10base2) cards
ESDI controller cards
The other system only has the HDs and ESDI controller card (no CPU card
or other cards). Also, one of the above systems is lacking the 1.2mb
floppy drive; it may be the same system that is lacking a CPU card.
I beleive 3 or 4 of the machines also have tape drive controller
cards; and I have three external IBM QIC tape drives to go with them.
I've also got a 15" monochrome IBM monitor that has a DB9 data cable
connector.
I've got some manuals (User's manual, problem determination guide, and
2-3 others) in the IBM binders.
Systems are located in Austin, Texas. You'll need a good-sized pickup
truck or van to haul all of them away. If you're interested, let me know.
It sucks to let these go, but I cant afford to move them along with my
other computer equipment.
I can be reached at mrbill(a)texas.net.

Oh yes, Tim (This could be a Tim-Tim conversation type thing!!!), that

Not my idea of fun. (Sorry, I didn't mean to sound hostile)
I've found 30 IBM 400 terminals for $1 a piece, in Western Massachusetts,
but no mainframe.
Anyway, I need systems, not parts (I need systems for the parts :-) .)
But if I get the systems, I'll get the parts. I can even use the most

Sure. Come up here with a lift-gate truck and I'll sell you all the
Data General Novas, 14" disk drives, and 1/2" 9-track tape drives
that you could want.
Tim. (shoppa(a)triumf.ca)
Here's a silly question, but one I've never understood:
Why can't a high density 5 1/4" disk be formatted in a double density
drive? When I try, DOS returns a "Track 0 Bad" error message.
I thought that a HD disk would simply have a denser coating of magnetic
material applied evenly over the entire surface of the disk. I don't
see why this should cause problems for a DD drive. However, a few
questions come to mind. Is the magnetic coating of a different
sensitivity, resulting in a weaker signal for the heads to pick up? Is
the magnetic coating applied to the media in "tracks", causing problems
when a different TPI spec is attempted on the disk?
Since some of the software for my "old" (first generation PC) computers
is on 5 1/4" disks of dubious condition, I would like to make copies
onto new disks. Since HD disks are still readily available and cheap, I
thought this would be an ideal way to do so.
I also seem to have fried the 5 1/4" HD drive in my PC while sorting
through some old software. It seems a couple of disks had some dirt on
them which caused horrible screeching sounds when the disk was spinning,
and also deposited a very hard black coating on the heads. The only way
I could remove the deposits was to scratch it off with my fingernails
(alcohol would not touch it). However, I must have bumped the heads out
of alignment, because the drive won't read disks any longer.
My question is: can I plug a Double Density drive into the same
connector in my modern PC and use it for my old disks? I know I will
have to change my BIOS setting, but is there anything else I need to
consider?
Any input on the above would be much appreciated... thanks in advance!
Hope this isn't too far off topic.

Yes they made them (1984)and sold for $249.95. Powered by batteries and 6k

Wow. I must admit, I thought that token ring required too many wires
for co-ax. Or was the 4-wire connection replaced by coax in, coax out?
Seriously, if it's IBM and co-ax I'd guess at SNA (Systems Network
Architecture - the famous 3270 series terminals and related devices).
This was not a PC network architecture at all - it was a loads-of-
terminals-into-the-mainframe architecture - and the card would have come
with terminal emulator software.
BTW, did anyone discover what the IBM System/74 was? The description
sounded more like a system/34 to me, and I certainly never heard of the
74 when I worked at IBM.
Philip.
Okay, I found a plug I forgot to attach. I plugged it in, switched it on,
and the breakers went POP!
Nothing burned, no hot smell...
Time to start rechecking things!

Actually, the 102 has the same size screen as the 100. Perhaps you're
thinking of the 200? The 200 is a clamshell design (iirc) with 24x80
screen. The 102 was simply a lighter, cheaper-to-make version of the 100.

It's funny that you ask this. My wife's uncle just gave me issue #1 of
PC World and issues 2 and 3 of PC Magazine. I'd really like to get my hands
on PCMag issue #1! He also gave me a late-model original PC *with*
theexpansion box (which I understand is a relatively rare item).
Anyway, he was a sales rep for IBM for the PC product, and he kept all
sorts of stuff in his attic. I guess that every summer, his wife makes him
clean up a little more. I'd say go to garage sales, or put an add in the
local newspaper. There's a juy who advertises every month in Nuts & Volts,
that he collects pre-1980 equipment, mags, etc. Maybe try the same.
Anyway, who knows what else he has up there. I've asked him to save a
copy of the IBM songbook for me <g>.

Yes, it is plugged in!
What did I do wrong? I got all the connections to the switches back in

Can you describe the Microsystem Executive? I have a Honeywell Microsystem
6, but no details about it. It is about 2 feet high, by 1.5 feet deep and
1 foot wide, finished in black and white. (The plastic front and back is
black, while the metal case is white). It's a very big beast for a micro,
and runs but a single terminal.

Good keyboards for taking notes:
Radio Shack Model 100/102
NEC PC8201A (M100, but some differences (or vice-versa?))
Epson HX-20 (Not as good, but adequate)
Cambridge Z88 (Never used one, but looks good.)
Radio Shack WP-2 (Word processor, similar to m100)
There are a couple of newer m100-type machines that can act as a keyboard
for a Mac or PC as well. And, of course, Apple's E-mate (or whatever it's
called.)
Or pick up a used '286-ish PC laptop. Generally decent machines, run DOS
(lots of available word processors), and cheap.

Where are you located? There are groups that will recondition them and
place them in schools. Groups like the Detwiler Foundation (huge) or the
Computer Recycling Project (tiny). I do the same for my girlfriend's school
with Mac's. There are also programs that teach kids about fixing them.

A simple question - was the Texas Instruments Compact Computer - the CC-40
- ever produced? I have some photos in a book here, and it looks neat, but
I have never heard of them and have no idea if they are available
second-hand.
Adam.
Today, for the first time in years, I got my old SwTPC S/09 to boot.
(pause for applause to die down)
But success was not total; floppy drive 0 works fine, but drive 1
just retracts to track 0 and makes a buzzing/grinding noise. I'm
guessing that it wants to hit track 0 at the beginning of a seek,
can't tell that it has made it there, and is struggling to retract
past the legal limit.
So, is anybody out there familiar with the mechanics of Qume 8"
floppy drives? Is there a switch or optical sensor or something
that tells it when it is at track 0? Or, from the description, is
it possible/likely that this is an electrical failure, like a dead
chip? Anybody got a service manual for one of these critters?
Cheers,
Bill.
