That is what it appears to be doing. I felt kind of silly after I stopped
and thought about it once I had posted that reply! BTW, does anyone know of a
good way of removing permenant magic marker from the plastic, such as the
cases, of these machines? Some of my machines were marked on by the various
2nd hand shops and such I bought them from, and I've never come up with a way
of removing the markings.
What I would like is Photofact schematics for Atari
computer hardware. I
have some, but I know I will be needing them when I finish my electronics
class.
I've never run across these. Were they something generally available when
the Atari's were popular?
I have a Timex Sinclair stashed in my closet, with a
box of tapes. I also
have something that is very similar to it, but I don't know much about it.
When I dig through my closet, I will report what I find, assuming anyone is
interested.
I'd be interested in hearing anything about any T/S stuff you might have.
Mine is the first computer I bought in 1982 and it is still boxed and all, but
doesn't seem to function any more. There aren't a lot of chips and such on
the mainboard of it to check for seating and such either!

Oh yeah, run into that one ALL the time! What has always worked for me is
Acetone on a paper towel. (ONLY in well ventilated areas!) Takes the
marker off and evaporates quickly enough to not harm the paint or plastic.
NOTE: put the Acetone on the PAPER TOWEL, NOT on the equipment! And
always dispose of the used paper towels in an OUTSIDE garbage can!

New subject: cover cleaning
I have successfully cleaned a few computer covers (plastic)
with hot water and ordinary washing detergent. Just leave the
cover in for half an hour, and use the dishbrush gently.
The results have been quite marvelous!
The acetone trick is also good, but don't rub too much or the
plastic WILL become soft!

This gets *some* markers that I've tried, and it's really good at getting
the goo off of cases without melting them: straight Naptha. You can buy it
at hardware stores.
However, it's *super* flammable, so if yer smokin' while you're cleanin',
you'll probably end up in smoke!
I've also used this to dissolve the spare residue from solder flux. It
works well, but again, don't get that soldering iron near it! (Especially
mine, it's butane fired!)
I've used this to de-goo 3 or 4 Tandy 200 laptop cases, and it's one of the
*very* few things that can safely dissolve wax. I learned this when I
learned about candlemaking.
However, it doesn't have much luck against smoke damage.
Hope this helps,

True enough, which is one of the reasons I specified putting the Acetone on
the paper towel rather than the surface to be cleaned. And then use
caution... Stopping to let the surface dry properly IS important!

to get stickers and stuff off computer cases - there's a product called
GOO GONE. It's a little less harsh than acitone (ie it's probably somewhat
less carcinogenic) and won't eat the plastic. Or at least it hasn't for me.
On a related note, has anyone found a better way than softscrub and/or
hot soapy water to get cigarrette smoke deposits off a system? My GS
was owned by a chain smoker from a family of chain smokers and I literally
had to pull each piece out of its case and scrub it clean (boy the keyboard
sure was fun) to get the yellow gunk off.

A: Two. One to hold the giraffe and the other to fill the bathtub

Ooo.. "Peanut" (PCJr) keyboards. Anyone have a spare? to sell? anyone know
if
the IR format is documented anywhere? (gleams of having one to talk to my

Sorry, don't have any spare PCjr keyboards, but I do have the technical
manual for the PCjr at home. If I remember, I'll type up the information
and send it to the list.

I bought a PC-jr for \pounds 10.00 (about $15) at a radio rally (hamfest)
last month. It was complete with the chicklet keyboard, but alas the
transformer unit (mains in, 17V AC out) was missing.
I 'phoned IBM, and amazingly the technical reference was still available,
and cost \pounds 45-ish. So I ordered it. It's a very good manual, with
schematics of the motherboard, RAM card, modem, disk controller, IR
receiver, modem (the only option I don't have), printer port, ROM
cartridge, PSU, CGA monitor, etc. There's also a commented source of the
ROM BIOS, and (appropriate to the above question) the format of the IR
keyboard data. The keyboard schematic is not in the manual, and nor is the
source code for the 80C48 microcontroller in the keyboard. But it should
be possible to use another IR transmitter with the PC-jr (or converserly
to use the PC-jr keyboard with another machine).

Yes, that is how a mailing list works, anything sent to the list goes
to all.

I own a few TI-99/4A systems (my first) and have been president
of the local TI-99 users group. I also have a Kaypro (CP/M) and a
TRS-80 Model 4P. (In the garage)
Try lacquer thinner to clean the plastic, it's worked for me.

Goo Gone is the key I believe. Cleans everything. Works great for those pesky price
stickers and old tape adhesive too. And it smells like oranges! You still have to be
careful if you rub too hard you can alter the texture of the plastic. But that goes
double for acetone and lacquer thinner. I've heard baby oil works for stickers too but
I
haven't tried it.
