In the interests of getting an old DEC PDP-11 running, I've got an STC
9-track tape drive here, a model 2921. This is, apparently, one of the rare
few that StorageTek (aka, STC/Telex) manufactured with a Pertec interface
vs. their own.
Based on conversations with a company that still maintains these old
beasts, it appears that the CPU card has gone bad. I'd like to at least try
and confirm this by swapping said card with a known-good one.
So... anyone own a 2921 that they don't mind it being used as a guinea
pig? ;-)
Thanks in advance.

I have found what seems to be a decent supply of eproms. I was looking at
an old 2400 baud fax modem for my pc, and noticed that it had what looked
like an eprom on it. I pulled the chip and peeled off the label, and it was
a 27256 eprom. I also bought a 2400 baud modem at a thrift store for $2.00
and it had a 27128 eprom in it. This was cheaper than buying the eprom by
itself. I paid $3.00 for a 2764, and didn't even price a 27128. I am going
to start picking up all of the old cheap, almost worthless modems and
grabbing the eproms out of them. You can probably pick up the modem for
less than the price of the eprom that it holds. If anyone else knows of a
cheap source of eproms or other chips, share it with us.

No. first it was not an 8080 replacement. Though it may have subbed for
8085 as they were very similar. Two the system had to be configured to run
8088 code(wich is not 8080 or z80 compatable.
I had done this to an 8085 system as the signals from the 8088 are the 8085
are very close.
The extra plug was likely the remaining 4 address lines (16 bit vs 20 bit
addressing).
If I had one I could trace it out and regenerate the schematic.

Hi,
New here but here goes...
The module was a "upgrade product for those wating a 8088 and having only
z80 cpu. By unplugging the z80 and putting in the card you could run 16bit
apps.
qdos was not a clone it was and outright disassembly of CP/M80 v1.4 and
reassembly to 8086/8.

I have available several PC100B Memory Extension cards for the Rainbow
for giveaway, or for trade if you have something that interests me.
At the moment, the cards are unpopulated, but you can generally find
256Kbit chips to fill the board for about a $1 junk PC card. (A fully
populated board has at most 3 banks of 9 256Kbit chips for a total of
768K and a system total of 896K.) I can provide a copy of the memory
configuration pamphlet.
I will give preference to anyone who has something to trade, but feel
free to ask even if you don't. If you have something to trade I will
even go out and find the $1 junk board and populate the card!
Here's what I am looking for:
1) BCC17 cable for use with a VT241 color monitor
2) Documentation for Rainbow Concurrent CP/M-86, especially programming
references.
3) Venix/Rainbow software and documentation.

I was checking the Polymorphic Systems computers I have against
the "The Big List" and found an 8824. It is a partial chassis but
looks similar to the others except it is designed for 8" drives.
Since it is not complete, I'll have to check in the Engineering
stuff to see if there is a description of it. I also found a
chassis model 88DS. It doesn't match with the number in "The Big
List" so I'll check further into that.
Regarding the others, from the "System 88 User's Manual",
copyright 1979.
1.1 SYSTEM 88 MODELS
The System 88 product line consists of the System 8813,
available with up to 3 mini-floppy drives; the System 8810
with one mini-floppy drive, and the 88/MS add-on with 2 large
floppy drives.
The 8813 and 8810 models are available with optional
double-sided, double density, mini-floppy disk drives. The
88/MS, an add-on storage for the 8813, is available with either
double or single-sided, double density large floppy disk
drives.
Hello,
I have been doing some image transfer in the last few months. I bought a Color
QuickCam for about $150. The resolution isn't that great but it is easy to use. I
also bought a scanner last month through Onsale for $139 + $20 shipping. It came
with Photoshop LE which I could sell (I already have Photoshop) for $30. Anyway
that brings the cost for a color flatbed (300 x 600) scanner down to $129. It
will scan photos with incredible resolution. Photo developing is $6-$10 per roll
though.
I've never used the camcorder method but I can't imagine it'll be any better than
the QuickCam. I did buy a TV card for the PC (I'm still putting together) for $65
a while back. I think it has screen/image capture software and video inputs. If
you already have a videocamera that would be your cheapest alternative. Besides,
then you can watch Gilligans Island on your computer!

I have an Acorn Electron going spare, if anybody wants it. It's a
"Plus 3", I've been told - it's the standard Electron, but with an
extra expansion module added on, containing a 3.5" floppy disk drive,
some ports, and who knows what else...!
It's in Manchester, UK.

You are right in thinking it's a protoype.
I used to work for Gavilan Computers back in the '80s and recall us
using Chisholm as our design house. If you can describe the unit, or
better yet post a picture, I can perhaps identify it as a Gavilan.

Help! My neighbor got a free computer, the Prolite from TI. Appears to be an early portable/luggable because it has a huge (at least 16" x 7" and 10lbs) battery pack, a 3.5 inch drive, a LCD display. What the heck is it? Does it run DOS and/or is it from the 80xx family?
Thanks in advance

I've had a storage unit for years now (PETs take up wayyy too much
room in an apartment, not to mention YEARS of COMPUTE!, Commodore, Ahoy,
RUN, Etc.) The big pain about the storage unit is having to dig through
the layers of goodies to find what you are getting at. Or even worse
knowing you have a tidbit on some subject in you think one of X
magazines, and you would have to dig through issues and issues (not at
home) to find it.
I specialize in my collecting, Commodore 8-bits and just recently
Atari 8-Bits. I would have to move to even think of another brand. :/

I have been shipping computers for a while now with no problem
whatsoever. I follow the guidelines already mentioned with a couple
twists:
Wrap the items in bubble wrap (best) or a plastic bag, anti-static is
best. This protects the surfaces and stops the styrofoam from being in
direct contact with the plastic on the machine. Keeps foam from getting
into the slots, etc. I also notice that the plastic in the cords
especially tend to bond with the foam after a while.
Popcorn in the bottom. Put the system in. Popcorn on sides and on top.
Allow for settling, compress it until it's firm. Seal it up.
If putting items on top of each other I'd put a piece of cardboard in
between along with a few inches of popcorn just in case things move.
This is for shipping. I've shipped lots of stuff packed in a single box
without a single casualty. Moving a short distance shouldn't be as much
of a big deal but if someone drops a box, you'll be glad you did it. I
didn't have any casualties when I moved last year either.
I get packing material from a couple sources. A camera shop here gets
about 5 big bags a month since all their stuff is fragile. A
manufacturer has a big cardboard recycling area where they dump boxes
and bubblewrap. If someone is near Mountain View, CA (near where I used
to live), I have a great source for tons of this stuff. Email me.

I'm going to be moving my collection a couple hundred miles from Austin,
TX to Tyler, TX. I'm wondering if anyone has any packing or moving
suggestions (packing material, special treatment of media, etc).
The stuff is going to be moved by a moving company (Atlas probably) but
I'm doing much of the packing ahead of time. I'm seriously considering
moving the oddball monitors and magnetic media myself. I don't trust them
with these easily harmed things and if they're damaged, they have little
or no reimbursement value, but are difficult to find again.
Anyone have any magical tips on packing and moving?

Okay, let's see if I can include the file this time. Sheesh. :)
Ok, this isn't exactly a classic computer. It's more the rebirth of a classic
in a slick new case (looks like a laptop, but isn't) with a slick new desktop.
If you don't think it's appropriate here, I won't be upset if you hit delete. :)
I got my Tiger Learning Computer (hereafter TLC) from Pennys today. The
outside box was smashed beyond all recognition, but the inner box, which only
touched the outer one in two spots, was intact, and the computer undamaged.
Inside the inner box was the actual retail box, with the pictures on it, the
"Apple Technology" symbol on it and so on.
It's an eerie feeling opening a brand new computer in retail packaging like
that. I haven't done it since I got my Commodore 64, after weeks of waiting
for it on backorder at LaBells (aka Best, now extinct) we picked one up at
KMart. You C=64 collectors probably experience this all the time, opening
a box to find *a computer* inside, ready to plug into the TV and compute.
For me, it'd been 13 years.
So what does $179 bucks plus shipping (box smashing was, presumably, free) get
in 1997? Well, you get a solid feeling little computer that feels remarkably
like an early power-book in your hands. You get the "wall wart" power supply.
You get 6 cartridges, one of which is your battery-ram "disk", another of which
has appleworks 4.3 on it. The rest each have a switch and two applications.
They plug (upside down) into slots on either side of the machine. But I'm
ahead of myself here.
Hookup.
Pretty much plug and play, although I did get a chuckle when I noticed that
this computer has no RF modulator. Now that everyone owns a VCR with video
IN jacks, it's not necessary anymore. So, white wire to audio in, yellow wire
to video in, power, flip the VCR input to line in, hit the switch. And smile
to myself as it boots up in prodos. Just for a second before the desktop and
sound effects load.
First annoying thing: The voice that says "Please select an activity" every
time you boot. I'm finding I boot a lot. I can tell this is going to irritate
me in the long term.
I'm not enough of an Apple 2 wizard to know what video mode it came up in. It
looks like about 16 colors, and about the resolution of CGA. Not as fine as
my old '64 was capable of, but much faster.
Using the thing.
Ok, I've owned it for about 4 hours now and I have a horrible crick in my neck
>from lying on the living room floor looking up at the TV, so I haven't
even tried all the apps yet. If anyone's interested, let me know, I'll follow
up.
Loading programs is almost exactly like running them off a floppy, except that
you can never boot from the program disk. You have to go to the disk icon
on the desktop and tell the tiger to run the program. Not very intuitive, but
I'm sure kids will figure it out as fast or faster than I did. Especially if
they read the instructions. :) I just expected them to load automatically.
My bet is in the next ROM version of the tiger they will.
Appleworks 4.3 looks remarkably like it did on my friend's 2E all those years
ago, except of course that it's not as sharp on my TV as it was on his apple
monitor. I suspect a newer TV directly connected instead of through the VCR
would perform better. That failing an old Commodore 1782 monitor should be
something to see. Wish I hadn't given mine away.
My nostalgia for Apple2 is limited here, like I said, I was a commodore 64
geek. WE didn't have to have disks to boot. (In fact, for the first 3
months I had my 64, I had no storage device at all, so my first programs
were short, enjoyed to the point of boredom, and then utterly lost when the
computer was powered off.) On the other hand, the odds of the '64 making a
comeback like this are slim and none. They never had the educational following.
So all in all, it's been a weird experience for me with this little computer.
Objectively, it's not a bad little machine at all. The keyboard bites -
although it may get better as it gets used/my hands adapt back from Microsoft
wave keyboard. The sound is first class - even better than my '64s old SID
chip. Graphics are about as good as can be expected on an 8 bit apple 2,
except in color. Software is still a little weird - nothing beyond what it
came with. Of course, if I can get my hands on a copy of "Kermit, a file
transfer protocol" and type in the 83 line basic Kermit so I can communicate
with the rest of my systems, I hopefully will be able to run all kinds of a2
software on it.
The weird part isn't objective though. Part of me is rejoicing at the idea of
this little throwback to the early 80s. I got a little piece of the excitement
I had unpacking my 64 the first time unpacking the Tiger. And seeing it abuse
my TV into pretending to be a computer monitor, even though it is a little
fuzzy, made me smile. This, for me is how computing was. Part of me sits and
scoffs at the tiger - and my '64 for that matter - when in the next room I have
a lan full of reasonably modern PCs with orders of magnitude more power. Even
my quasi-classic GS is head and shoulders above the tiger as a computer. But
the tiger has something none of my other machines do. I'm not sure what, to
be honest, maybe just nostalgia, maybe not.
Anyway, I'm keeping it. Even if I do keep expecting the flip top to have a
screen in it. (at least it comes off. :)

perhaps it is time for this group to stand up and begin to truly capture
the history and documentation of classic computing - and to do it on line.
for starters this means capturing manuals which are all too often lost
first. next (and more challenging legally) is software. we could use some
solid legal advice on what can and can't be posted but i find it hard to
believe that anyone could object to putting scanned-in versions of most
older manuals on the internet since: 1) many of these companies are no
longer in the business, and 2) even if they were they would probably
themselves make such a service available or welcome a third party to do it.
i think all we really would have to do is make sure the original copyright
notification was preserved in the on-line version. i realize system
software is a tougher issue but perhaps we could start with the manuals.
so we would need a home location (Bill Whitson: how about the "Archives"
section of the classic computer web page you've set up?
http://weber.u.washington.edu/~bcw/ccl.html) and some folks with scanners
who can get things into HTML format (and others? .doc? .pdf?) and upload.
comments on this proposal? are there already similar archives out there? -
