Visual 102 with keyboard
I'm going to ask $5 for each plus shipping to more or less cover the
time involved in packing and running these to the shipper, but otherwise
they're here and awaiting some interested foster home to contact me
about them. Neither weighs a lot but due to the glass crt they aren't
featherwight either.
COntact me directly. I'm in the process of finishing my new shop and
these are NOT going into it and taking up much needed space.

I think you guys were right after all. It's a futile endeavour.
I just trashed the AT case and the entire PS/2 system except the
drives, cards, and ribbon cables. I couldn't stand it anymore. I will
pick up another case, there's plenty left that are not necessarily
PS/2. The thing did have an expansion card that had 2 MB RAM on it,
I will ship it to anyone who wants it.

I've been revising my web site a bit recently. One of the things I've
added is the entire 1978 Tandy Computers catalog which features such
things as the IMSAI 8080, Sol-20, Vector 1, etc. I don't know about
you, but aside from this one catalog, I had no idea that Tandy ever
sold anything like this. At any rate, the whole thing has been
scanned and put on my web site. I tried to keep the page images small
so they don't take forever to load, but it means that you can only
read the tag lines and prices. Still, the pictures and prices are fun
to look at. Take a look and let me know what you think. If there is
sufficient interest, I might go back and scan the pages at a higher
resolution and link the bigger images to the current ones. Also, let
me know if you see any glaring errors on my site; I'm still tracking
down some minor formatting problems, but most of it should be fine.
Just pick the "classic computers" link on the first page and go from
there to see the catalog. Hope you enjoy looking through it as much
as I did!

OK, despite your warnings, I pulled my AT motherboard out of its case
and put it into the PS/2 tower case. It fits reasonably well
physically, but I AM having a bit of trouble with the power supply
conversion. I have pretty much figured out how to wire the psu
to the motherboard, but the problem is the power good line. What
is it, and what would I need to hook it up to for the PSU and MB to
think that the power is good? (this is line 1 of P8 on most AT
motherboards)

I have a like new, great condition DEC PC 100+ (Rainbow?) with Seagate
St412 10mb hard disk and dual floppy. One problem...NO monitor, NO
keyboard. I'm sure these can be located though. The power supply case
indicates a manufacture date of December 14, 1983. The unit looks as
though it just came out of the box, other than the little DEC plate in
the upper left corner of the front missing. The other one that says
"100+" is intact though. I have no idea why this is missing.
Make me an offer. Cash or trade or a combination. I'm always looking for
PC components such as internal/external cdroms, sound cards, SIMMs (30
or 72 pin, parity if possible). Best offer gets this one.
Email me directly.

Jinsam is a database management program, and I remember the ads

NASA application for PETs in an early Micro magazine (sometime in 1980)
something to do with launch countdown of un-manned missiles. As I have
said before, it my not have been a graphics superstar but it had the
interfacing (IEEE-488 and parallel user port) for just about anything
scientific.

That was in Modesto, CA, (My vacation this time is closer to home). I
think the proboability of those units being there are good (since most
of the local 'thrifters' snag the IBM, Mac, and Amiga machines that show
up). I would have gotten them myself but those PETs take up alot of
shelf-space (which is limited for me cause I have several PETs already),
and I was pretending to be strong (of course if it were an original PET,
an 8x50 dual drive or a B-128 it would have been bought. :) That chain
of thrift stores (they call themselves Thrift Center Thrift Stores) are
interesting, on Wednesdays and Saturdays they have 1/2 price days and
with their sometimes low prices you can pick up some really inexpensive
hardware, they also strangely have been a good source for Atari 800s.
Yesterday on our travels, we took off to Sacramento (California's
state capitol) and discovered in our wanderings SEVERAL THRIFT STORES
(Many within a square mile on just one street.) But given the time we
didn't stop, *sigh*, but we now know where to look next time. We did
stop at a warehouse sized used book store (on Power Inn Road) most of
the stuff is discontinued school texts, some assorted stuff... Not much
computer book pickings there unless you have an IBM, Apple II, or a Mac
(finding quality older computer books almost the most challenging task
only after finding software.)
Been wandering the valley for most of this last week and plan to rest
out at least today and possibly tomorrow before work on Monday.

To Greg Troutman:
I received the Laser 50 in the mail today... just as promised!! Thanks a
ton, and I hope you received my end the bargain as well?
To the list, I posted this here just as an example that there are
successful trades that take place because of the correspondance on the
list. Greg got in touch with me because I posted information about some
Apple cards that I had. We talked a bit, and decided this would be a
fair trade, neither of us had worries that the other wouldn't come
through on their side of the deal. It turns out we both sent our
hardware out the next morning, and 2 days later I received mine! Boy
Greg, I hope you got your ok... let me know.
Anyway, that's all. Just some publicity that trades can go right, after
having some bad experiences in the past, this re-opened my eyes to the
possibility of doing more often.
Thanks,

Just received by email from the original owner...
"When I got the DL8a there were only the 4 EPROMs. Not sure what's in them
though, I found the what I assume was the code in the EPROMs when stepping
through memory, but I couldn't be bothered trying to disassemble it. "
I guess this implies that it was probably working, and that it would be safe
to power-up and step through the memory myself. Any agreement here, or is
this a bad idea?
Cheers

Well the bottom line is... I'm not an electronics guy.
The option I will be following is getting the 1702A EPROMS copied and
a) backed up to several media formats
b) duplicated to new 1702As.
>I supose the solution is for him to build a 1702 reader (which is a lot

No, this isn't a solution. I'm a software guy - I'll re-engineer the 8080A
code if and when necessary, but there's no way I'm going to build hardware
for this thing. I just want to copy some EPROMS... not delve into clever
engineering to make them redundant! By the way, I have found several 8080A
disasemblers for MSDOS. THere are quite a few websites around carrying such
goodies.
> Or the one that's
>X-rayed with a sufficient dose to damage the chips, or the one that's
>lost, or whatever.
Is the X-Raying a valid problem? Will X-Rays further damage already fragile
EPROMS? As I said, I may have found myself four 1702A EPROMS, the only
problem here is getting the code from A to B. Maybe the ideal solution
would be for me to borrow a 1702 reader and do the job over here. That way,
the irreplacible EPROMs don't travel at all.
Cheers
A
OK, I've kind of settled on an approact to restoring the DL8A. I figure I'm
completely unqualified to do any of this and so will rely upon advice and
help from those of you who are.
I think the first and most important step is to back-up the extant 1702 boot
program. I've been thinking about this one (re: bit rot); would it be
possible to get a disassembly of the code to see if it looks OK? It can't
be too big - only 4 eproms total. Does bit rot proceed on a bit-by-bit
basis, or are whole segments knocked out at a go (ie: bytes/multiples)? I
presume that it will be possible to restore the boot program if there is
some significant part of the eproms intact - opcodes anyway...
The disassembly should give some clues as to operation of the machine, too.
So, firstly I ask if anyone with a 1702 programmer who would be prepared to
handle copying these 4 eproms for me to wave their hands in the air. I'll
also need 4 of the 1702 eproms, so would appreciate anyone with those to
also wave their hands. And finally, I'm looking for a PC based 8080A
disassembler. My plan is to pull the chips and airmail them to a kind
volunteer. Actually - although I don't have a lot to spend - I will be most
happy to pay for the preservation (restoration?) of these data. I think its
important.
I do believe this machine is possibly unique; certainly rare - and worth
restoring properly. I would note that the cosmetics are near flawless;
this bodes well for the electronics inside, no?
Cheers

I've deleted most of the old accounts - The disk was at 8% free when I got it,
now it's at 88% free... The accounts remaining look like they have system
stuff in them, or are refrenced in the start-up files. I'm backing them up
to DECtapes, then deleting them to see what happens. If it runs a month without
the files on the tape, I wipe the tape. (Write nulls over it)
I'm moving the 44 to school, there I'm going to attach it to the nameserver
(Linux) and kludge up something interesting so that people can telnet to the
RSTS without having to have accounts on the Linux box. Right now I'm working
out a plan with the 23+. The move is scheduled for Monday. Fun! I get to lug
the RA81 up a flight of stairs! :)
Oh, and does removing the account (With REACT) kill the directory by NULLing
over it, or do I have to go do something else to make sure they're gone?
I did see a few accounting-type things in the [5x,*] area, so I killed them all
sight-unseen. The system runs OK now... Kermit is still here, I assume I can
keep that... OPSER and the batch stuff are missing, and the OS source has been
removed, but if Kermit works I may be able to go find some nice person
with 8.0-07 and get the files needed. I renamed the machine GALAXIA, and
made a copy of the old Monitor .SIL so I can kill those too.
Basically now, without some real digging, you can't tell where the machine came
from.

Several weeks ago I posted a question about whether a standard
PC DD/DD drive could read/write ATARI floppy disks. I got one
responce which was in the negative... however, at the time the
comp.sys.atari.8bit faq wasn't available from my news server (both
comp.sys.atari.8bit and news.answers). Well, it is now and I have a
correct answer. Check:
http://www.faqs.org/faqs/atari-8-bit/faq/
Subject: 11.2) Can I read/write 8-bit Atari disks on an IBM-PC?
There are several programs that allow an MS-DOS system to work with an
Atari-format diskette. The following require a DOS and disk drive on
the Atari end capable of the SS/DD 180K format:

Guess it's time to get DosEMU working again. ;-)

It appears that what is happening is that the mail sever with the fulll

better than bouncing the mail to the list as a whole but not as good as
bouncing it to the list administrator who can then drop the offending

Well, I scored an Apple IIc with an external Floppy drive,
Imagewriter printerer, and small composite green (maybe 9"?) monitor.
$20 bucks. I also got some disks with it, but no games - mostly old
nibble magazine disks. This thing has a serial port on it, anyone
know what the pinout is and if these ports are compatible with
Macintosh adapters? If not, what's the pinout and can I buy the DIN
plug from Mouser? And hell, while I'm at it, where can I find a
terminal program with x/y/zmodem capabilities? Is there anything like
XIO2PC on the Atari for the Apple? Anyone know of a web page which
documents DOS commands? Gee, I'm just full of questions.
I'm still looking for a cheap source for DD/DD 5 1/4"
floppies. The office supply store down the street wants $10 for a ten

I've searched the world web over ,but never did I find......
There seems to be a lot of info on Mods. 1,3,100,Coco etc. but nada
on this beast. Any sites I might have missed ? Merch , Cord ?
What I have is a TRS Model II with 1 internal 8' fdd and 1 external
fdd , 3 humungous 5Meg hdd ( about the size of a large XT) , K-B ,
TRS model 7 modem , and a box of 8" disks with CP/M 2.2 , TRSOS,
Scripsit and a bunch of other prgms.
When I boot up with or without an OS disk I get a "boot error ht'
msg. The dd spins up and sounds like its loading. Could it have been
set up to boot off one of the hard drives ? I'm really a novice with
TRS-80s but have Coco 1 and 2 in my collection and a Scriptsit cart.
Is there something I'm not doing ?

That's what you would referr to as using proven technology!
This reminds me of a story about the HP calculators. When the HP 35
calculator came out some of the US Army artillery men at Ft. Sill saw how
fast they were and their accuracy so they put in a requision to buy a bunch
of them. The Department of Defense liked the idea but they had to have a
feasibilty study to justify the purchase, so they spent $150,000 for a
study that took two years and end the end the study did show the costs of
the purchase to be justified. Next, the army went to HP to buy some HP 35s
but they found out that the 35 had been discontinued and had been replaced
by the HP 45. They tried the HP 45 and found that it was even better, so
they requested that the HP 45 be purchased instead. Again the DOD liked
the idea so they commissioned another $150,000 study to justify the
purchase of HP 45s. After a year and a half, this study also found the
purchase to be justified. The army then went back to HP to purchase their
HP 45s and .... You guessed it, the 45 had been discontinued and had been
replaced by the HP 55. So the army requested that HP 55s be purchased. The
DOD commissioned a third study (only $100,000 this time, the beltway
bandits had this down pat!) to justify this purchase. This time the study
only took a year. Again the army personnel rushed to HP to buy HP
calculators, only to find out that the HP 55 had been discontinued! The
artillerymen gave up and went back to their charts and tables!

the pinout is proprietary. this is a ps/2 remember? the form factor is not AT

model 60 is 10mhz 286 with 1 meg. there are chips to upgrade to 386 from 286,
