Thanks Jim. Have you replaced the video ram in the Sol-20 before?
Also, do you know if parts are still available or will I have to
cannibalize from a similar vintage pieces part?

The '$'s indicate a single bit error in the video RAM. Bit 3 is stuck.

William,
I'd be interested in the Sphere, SWTPC gear, etc you don't want.

Well, lets see. I am 28 or so, living now in Carmel, NY (about fifty miles
north of NYC), and like old things in general. Mostly. I am employed by
one of the ISPs (originally the first ISP - the NSF) as an engineer. As
you can probably tell by now, I tend to pick up the scraps of the network.
I originally collected old radios. I had a small collection of consumer
sets, some working, but dropped the hobby when two others came into my
life - computers and old industrial/military electronics. The latter is
simply from my consumer radio collecting days. The computers, however,
probably started with the Apple II, like so many other kids in grade
school.
The first computer I ran into is my old DEC PDP-8/S, purchased "thru" a
hamfest back in 1986. I was eyeing someone's PDP-11 boards (I was already
a hamfest regular), and a man approached me with an offer I could not
refuse - for $5, I could have a real, six-foot tall computer. I still have
the machine.
After that, I started getting others - mostly PeeCee and small mini
machines. Sometimes they were pulled from dumpsters, other times they were
purchased for a song. Right now, the collection consists of a PDP-8/S,
PDP-8/E, PDP-11/23, PDP-11/34, Interdata 14, IBM S/1, IBM 5100, Sun 3/50,
3/60, 3/280 and 4/280, SPARCstation 370, SGI Iris 2500T, IBM
RS/6000/T3B, and HP 2100A. Some machines work, some need work. There are
parts of many others, but I am not counting those.
I also have a bunch of ancient Sphere/SWTPC/Exorsisor stuff that I need to
get rid of (I have no interest in it). Most of it will migrate to RCS/RI
(so Allison can play with it).
In addition to old computers, I collect old Naval radios and radar sets
from the 1930s and 40s, as well as vaccuum tubes. At this point, I do not
know which collection takes up more mass, as some of the shipboard radio
transmitters are six foot monsters as well. Look at some of the old
serials from the 1950s - they tend to show up as props in monster labs.
And I do not play bassoon. I also voluteer time as part of the restoration
crew on Battleship Massachusetts - a place with _real_ computers. Sorry
guys, but engineering and craftsmanshipwise (is that a word?), the
mechanical fire control computers are far more impressive than any of the
digital stuff.

I'm 43, started playing with computers before high school. That was less
common then, though maybe not for the folks on this list. My dad had a
"portable" Teletype model 33 (I have it now) with an acoustic coupler
modem. He had accounts on GE timesharing (BASIC) and the nearby
University of Wisconsin Burroughs B5500 (I used WIPL, a little like
FOCAL.)
I got a BS in EE and MS in Computer Science at UW, where I ran PDP-11's
etc. in the CS lab. Have mostly worked at Intel in Portland since then.
No time for more bio now, but there is some more info on how I started
collecting on my web site.

Do you still have it?
Is it free :-)
If yes to the above would collection be possible at the weekend if I could
arrange it?
Regards
Pete
While we're at it (the buisness of veering grossly off-charter), who
else here collects electronic music equipment of about the same vintage
as the computers discussed here? I have a Korg Poly-800, Yamaha DX-7II,
2 FB-01's, CS-01, a Sequential SixTrack, 360 Systems MidiBass, and a
homebrew MIDI interface to hook some of this to my Amiga. I have
grandiose plans (ok, ok, not _so_ grandiose, but everything is relative
these days...) to rip the 6581 out of my C64 (or better yet, find an old
otherwise nonfunctional C64 and rip the 6581 out of there) and hook it
up to a 68HC11 SBC I designed a few years back (the company I used to
work for is still using and occasionally producing these) and
controlling it (the 6581, that is) via MIDI as a cheap-o (and physically
small) analog synth. (Cause let's face it, that's what the 6581 is...)
BTW Any of you UK guys have collections of the old E&MM magazine? I'm
missing 1 or 2 issues in the 84 (83?) season...

I think I have that card set (but not the roms - but I do have a spare
ka630 board) with full instructions. I can dig up specifics over the
weekend, when I'm back in Montreal. My uVaxII does have the ability to
act as an X client - I tried it, I have the 3 Tk50 Ultrix distribution
set (but who wants that if you can have NetBSD?) I think it can drive
the GPX cards too, but have never seen it do so myself - I don't have a
monitor to hook up to it.
If anyone wants the cards (the GPX and the spare ka630), they're up for
grabs - either for sale or trade since I'm not doing much with the VAX
(I like my Sparc better)

Greets:
Yep, this last weekend I picked up another truckload of goodies. Mainly
Apple stuff but there is some TI, Mac, IBM, etc., stuff in there. The
list follows here. Please let me know if you want any of this! Amazing
how, until two weeks ago, I had very little Apple stuff, and now I have
more than I can handle!!
Also, for all of you who responded the last time I made a similar post,
thanks for doing so! Your help on identifying many of the items was
great. And for all of you who have requested stuff, I apologize in
getting back to you in such a deliquent manner.... the e-mails are on
file, I've just been so busy lately! I will get back to you and get this
stuff out to you, that's a promise!!
Please take a look at the URL in my signature at the very bottom...
there's the complete inventory of what I have on-line, and also pages
for what I am looking for. Other pages I have there are some interesting
links, an Adventure International page (the classic game company-- Scott
Adams), my autographed memorabilia page, classic computer photo gallery,
downloads, and this 'what's new' list, and some other stuff you may like
to browse.
Anyway, here is the recent list of what I just got. Let me know if you
can take some off of my hands or have some info. on it, ok?
Thanks for your time,

-------------------
*Archer joystick for a PC. It has a fairly 'tall' stick on it, with two
buttons on the front. Also has trim settings, auto fire option, A/b
selectors for both directions, and four suction cups on the bottom. Has
both 15 and 9 pin plugs.
*Joystick.... I'd like some information on this one. It is a tan box
about 5 inches by 3 inches. The joystick itself is just 2 inches or so
tall. Has trim settings also. Two buttons, which look like classic
self-destruct buttons or something. Is was made by TG Products of Plano,
TX. To connect it to a computer, it has a long blue ribbon cable (inch
wide?) with 15 pins on the end. The pins are just out there all by
themselves! Is this for an Apple computer?
*MCP AP-16 Memory Module: I would like some info on this. This is some
type of expansion card, etc. It is about 8 inches long and 3 inches
wide. It contains 18 chips, 10 of which say AM9016EPC & 8248FMP. The
other chips are labeled SP225, SP229, P218, SP245-b, SP220, and SP238.
The card also has a red switch on it. Really no other information...
oh, it also has 4 led lights. Please let me know something about this!
*Expansion card of some sort for the Apple //e. This is about 3"x2" as
is (c) 1988 by Applied Engineering. It says ][e 64k on the side by the
'plug-in', and on the other side is says KEYBOARD. Please let me know
how this thing is used!
* 1.5 foot cable. Adapter of some sort. Looks like a PC joystick
adapter. 15 pin male to 9 pin female.
* Joystick -- called Laser Joystick. It is small has has 2 buttons on
the side. I know of the Laser computer series, etc. (I have a Laser 300,
some kids computers, and want a Laser 50!) by V-tech... didn't realise
they made joysticks. Has a 9 pin connector on it. Does anyone know what
computer this was for, or when it was made?
* Some type of expansion card... presumably for the Apple. Has 19
various chips on it. Made by Data Technology Corp. Would love some more
tips on what this might be.
Software

I have one of these, but I'm afraid I can't help - the version you speak
of should be the Microbee 64 with the Computer-in-a-book combined
disk/drive power supply etc. I only have details for the 16k version.
Nevertheless I'll try digging them up and see if they help, but hopefully
someone else will be able to tell you more. The manuals I have lack
details.
