Has anyone got a service manual handy for a MiniScribe 3438P?
I yanked one from an XT clone to use with my SwTPC S/09, but
it won't format, and the most obvious possible problem is the
jumper settings. There are four that are obviously for drive
selects 0..3, and three others that might be the troublemakers.
I've tried some random settings, and in most of them it comes
up to speed okay, selects, and then after about three seconds
starts a probably unhealthy wobbling, sounding as if it is rapidly
seeking a million different tracks, one after the other. In
at least one setting, it doesn't always recognize when it has
got up to speed, and continues ramping up to a frightening pitch.
With the jumpers set as they were in the XT, it selects okay,
but I get error messages any time I try to read, write, or
format the thing. It still works okay in the XT though.
Anyway, help would be appreciated. I've already searched the
web quite a bit. Found some specs, and a thread in which people
were looking for the right settings to use in a PC, but nothing
about what the jumpers mean (or how to set them for an S/09!).
In other news, I recently realized that I can upgrade my S/09's
memory just by slapping 4164's into the unused IC sockets. I
had a few lying around, so it got an immediate 64K upgrate. 192K
more is on order. I can still remember when this would have
cost money! :-)
Cheers!

i saw a complete tandem computer system for sale for $8 today. it has the
usual desktop case, a monitor and two external 5.25 floppy drives with what
appears to be a seagate mfm drive with each floppy drive! the system is
complete, and everything is connected together, but was unable to test it. is
this thing worth getting, or is it just another pc compatible? i have plenty
of xt and 286 variants to keep me going for a long time. if its something
else, or has significant historical value, i'll go get it.

I just got an IBM Series/1! This is going to be fun, but it's going to take
a long time to get running. It's filled with more dust than I've ever seen
in a computer, and it uses 230v which means I don't have much of a choice
of where to plug it into. And the manuals... That's going to take WEEKS to
go through! But hey, I got four 200MB hard drives, a 4956-K00 CPU, a few
I/O units and an 8 inch floppy drive out of it! Whheee! I LOVE those 8 inch
drives!
OK, thats going to take a while to sort through everything. On to the PC card.
I found this strange 8-bit card labeled:
Scan Doubler S/N 1179
PGS P/N8403001
It has two DB-9 connectors on the end, and it was pulled from an old PC.
It's probably about a half length card. Any ideas on what it is? I was
thinking some sort of dual-monitor video card...

The T 1-3/4 size exists here in the US, too, but I most frequently I see
it in referring to LEDs. The T 1-3/4 incandescent bulb size is E-5 (for
5mm), I think.
Anyway, so long as I am replacing these lights, why can't I replace them
with amber LEDs? I figure that I can plug an LED-resistor combo into the
same socket and tune the brightness with the resistor. I remember reading
somewhere that the lamp power is 8v. I'll test it first, but does this sound
right?
Thanks for the info, Tony.

Speaking of Osbornes, I recently ran across an Osborne 4 (I didn't
even know they went that high), in a nice blue and white molded plastic
case. The keyboard (kinda small) flipped open on hinges to reveal a
9"display, and couple drives (I think there were two), and given the
portables of the time it was reatively light! Was able to attempt a
power-up but no display... Bummer at $15 It almost went for the VFC 2.0
sale booth.. :)
===================================================================
Did some updating to the PET FAQ, some notes on how to program sound.
including a table of the notes you can produce, a listing of the
extremely small but useful tape2disk program, etc. Next probably will
be PET memory maps (all three ROMs, orogonal upgrade and 4.0); I have
been attempting this the lazy route of scanning them in, but the books I
have all use such small point sizes that the OCR program has problems
translating. I will try to use a copier to enlarge them someday soon.
I have cleared space on one of my desks (my brother is now a proud
owner of a complete Amiga 500 system, which of course, I will still have
access to) to set up a PET after a few years without easy access to
one. This PET (32k upgrade ROMs) needs some work as one program keeps
locking it up, I suspect it may be one of the 6520s... It also needs to
have the RAM checked (anyone know a source for 4116-4s?) Once I get
comfortable working with this one I'll switch and see about getting the
SuperPET running and also the original PET (which I really want to get
to, as I now have an EPROM programmer to read the ROMs with.)
Another recent arrival is a package from DigiKey of 10-12/24 edgeboard
connectors, for making a PET joystick adaptor, a mini-networking project
I've been thinking about, and I may try this 'PET composite Video
Adapter' I have plans for to see if it actually does not work as Enrico
has warned me...
The PET shares space with a VIC-20 (also recently set-up) and maybe if
I can squeeze it in, a Plus/4 too.. Then I would have a large portion
of the Commodore 8-bit models runnable (C128, C-64,
Plus/4, VIC-20, PET). Some of my plans would be to refine my disk
collections and work up some menus and utilites for each of the machines
(including some sort of standardized compression/archive utility).
I am anxiously awaiting the new year as many more families upgrade
their older systems to something more contemporary and take their older
ones to yard sales, flea markets, and thrift shops (or maybe call me to
take them off their hands.)... ;)

We have four 11/73 cpu cards in our museum collection which will run
the ODT but cannot execute any instructions. We suspect the CPU chips.
Can anyone source the cpu chips or the entire board at a reasonable
price or service the boards at a reasonable price.
Ditto MicroVax II cpu boards.

It looks like I may have a line on a couple (maybe three) of PDP-8/E CPUs,
and while I intend to pickup one of them for my collection, it may make
the deal easier if I take more than one (perhaps all) of them.
So... anyone out there looking for a PDP-8/E to call their own?
At the moment, I'm trying to gauge interest. Prices have not been
finalized yet, and they are on the East Coast, so shipping will be a
consideration as well.
If you are interested, please drop me a note (please don't reply to the
list) and indicate what one would be worth to you, and what options you
want (need) to have...
At present, it appears that all of the available units will have at least
16k of core, and EAE.
The units are reported to be in good condition, recently removed from
service. CPU chassis (box) only, (to save on shipping) none of the 6
foot 'corporate' racks... (unless someone *really* wants one)

I don't know, I'm afraid. (I think, though, that it uses a standard IEC
line cord? Or is my memory gone?)

If I were lucky enough to be going to Canada any time soon, I buy it off
you, but I already have several, and can't really justify the shipping
costs. (Especially right now. 8^( )

The AC adapter is still available from Radio Shack although at a premium price - about $25. There is also a 16K memory add-on that can sometimes be found used on the net.

$24 doesn't seem like such a bad investment. (You could get that much for

Before I start tearing apart my two "new" RK05 drives, can anyone tell me if
the panel lamps are removable without soldering? I have a copule of lamps
that need to be replaced and I can't see too well into the cavity.
Also, I'm looking to get rid of two DEC 200/MC remote access concentrators
and a Multi-Tech modem rack. The modem rack is cool, filled with 12, 2400
baud modems. I got these as part of a 6' equipment rack (which is now filled
with a PDP11/34a).
Also, just an aside. I sent the now-infamous Altair scans tape to Bill
Whitson. I would assume that in the next two weeks they should be posted to
the ftp site (assuming that they pass Bill's tests!)

I might be able to help - I came across one recently but haven't had the
chance to stop by to pick it up. Anyway, the MC-10 or Micro Color Computer
(I assume they are the same thing here - if I'm wrong please discount any
comments I make here) cost around $120 when first released, and it was
intended to compete with the Timex and VIC-20. (And, I imagine, the TI 99/2
- did any of these ever appear?) I don't know of its success as such, but
as I have only seen the one I suspect it was far from great, especially
considering that it was released late (for a ultra-cheap throw-away
computer) against stiff competition. According to my info, video was 16
lines by 32 characters (uppercase only) with 8 colours. Apparantly there
were also 16 graphics characters. It came with 4k RAM, expandable to 16K,
and used the Motorola 6803. It has sound, but I have no idea about how
good it was, and, as per normal, used cassettes for storage.
They look keen, anyway. The one I am after was marked at $100 - they tried
to tell me that was the price. I doubt it was much more here when new. :) I
managed to talk them down to $15, but that was $14 more than I had on me -
so I need to go back and get one of my own. Maybe this weekend.
Hope that helps,
Adam.
Dear Sir:
I have been looking for someone to format and copy some hard disks used
on an iRMX system.
I noticed that you mentioned a company - InBUS - that repaired some of
your equipment. I searched for references to them but found nothing
promising.
Perhaps you sitll have some information about them. If so would you be
so kind as to pass along their contact info?
At any rate I hope it all worked out for you. Ahhh... the joys of
"Legacy Equipment"!
