Apple recommended that when this started to occur, you picked the Apple ///
a couple of inches off the table and dropped it to reseat the chips.
I'm not suprised that they weren't the success Apple had wanted. :)

Here is something new:
I just read a newsgroup post about a (somewhat) poor soul who has
gotten a PET 2001 with a rusty case looking for re-finishing/painting
suggestions. I suggested he subscribe here and ask for help.
Thinking about it this is a cool topic for discussion, has anyone
re-painted their computer cases and what tips/suggestions do you have
for us or what should we avoid (also got any good color schemes?). (I
have a few 64s lying around that would look neat with a custom paint
job, since they are plastic, what do you suggest?
I remember a letter in one of the Commodore mags on how to remove and
re-set the alphanumeric decals on a keyboard, maybe I sould spend half a
day in the storage unit and find some of this stuff... :/

Sounds like just unseated chips, this was very common for this unit, I have
4 myself. Take off the cover and push in all the chips checking for
corrosion. After you remove the top you can remove the motherboard on its
mounting plate from the bottom. If you pull out the titan cards you also
remove the video bios. Unless you have the old chip to replace the chip
the cards are attatched to, you can't boot the machine.

If you think that is a problem, try collecting in Australia. :) Pretty
much no competition for old computers (as far as I know I am one of only
two serious collectors in the state), but also almost no systems.
Everything seems to be in the US, but here the only common computer seems
to be the C64. So the values are horribly confused. On the plus side, and
awful lot of people are willing to give away their computers, as there is
nothing else to do with them. That's how I got my Lisa, for example. When
asked how much I think a given system is worth I invariably find myself in
a quandry, as there are very few of them (whatever it may be) but also
very, very few collectors. As an example, the Mac 128 I've seen from free
to $200, with $50 being the most common, the Apple IIc ranges from $5 (I
bought it) to $100, and the Amstrad CPC6128 goes from $7 to $150. All of
this in the one city. How do you advise people how much their system is
worth in that sort of climate?
Mind you, I just picked up (last night) an Tandy TRS-80 Color Computer I
for $20 - high, I thought, until you realise that it was new in box, never
even plugged in.
Adam.
I agree and have been saving old ads, promotions give away's and the like.
My library is very large and contains over 500 books. Keep computing !

Interesting. I only once (I think) ever used a System/38, so I was not
very familiar with it. But I used a S/34 a lot, and when I had to write
software for a PC front end to a S/36, found the S/36 very similar from
the user interface point of view. Also, the 5360 looked physically like
a more modern 5340, complete with an updated version of my favourite
floppy drive (23 disks in one drive!). Alas, I never found out what
became of the old 5340 that I worked on (this was as a student before
university) - when I went back for a vacation job, it had gone, and all
the software had been moved to, you guessed it, another 5340!
I also once posted to a newsgroup within IBM, "Is there a similar group
for 5300 series minicomputers" which received the inexplicable reply,
"The system/38 isn't a minicomputer." (The S/34 and S/36, in which I
was interested, certainly were, so why wasn't the S/38? On the other
hand, the PC graphics terminals 537X weren't.) The group did exist, but
I never read it much in the end.
Still, enough reminiscing. Does anyone know if there are any S/34 or
even S/32 machines still around? I once had a short e-mail exchange
with someone who might have been going to acquire a S/34 but AFAIK he
never managed it.
Philip.
I have a friend that needs software for a Kaypro I and a 4+88 (I have
never heard of this but he says he has one). Would Don Maslin have the
system disks for these beasts? Or anyone else?

third time trying to send this message ?
I have a 5110 cpu unit but had to leave the drive unit and printer behind :(
If you can get the 5120 it would be a great find for your collection. The
data storage could be either 1.2 M or 2.4 M on the 8" floppies. The machine
was announced in March of 1980 and was the successor to the 5100 and was
based on the 5110 Model 3. Also Basic and APL are in ROM. Good luck with it.

Hi all:::
Just acquired an Apple III with 256k ram and a Titan III + IIe board.
When I power it up I get a beep and the ram test begins. After this the
screeen fills with text, sits for a minute and then goes back to the ram
test. If I hit the reset button, it will boot up. Is this normal. If I
tried pulling out the Titan cards, but then it doesn't even get that far
(Just some hires graphics giberish.) Is the 6502 on the titan board?
Finally, I read somewhere that you can replace the 6502 on the titan card
with a 65c02 for enhanced //e support. Any ideas if this is fact or
fallacy?

Anyone know anything about the Sanyo MBC-3000? It's a desktop (like a
TRS-80 Model II, kinda) with a built-in monitor and two vertical 8" drives
on the right. I think it's a CP/M machine, but I'm not sure. (All I found
on the web was a place in Aus that can do data conversions.)
