Possibly, I am roughly equidistant from M20 J8 and J9. Where are you?
If I arrange to share a car I won't let apathy reign on the day.
My best MPG car is about 23 so maybe not one of mine though my supercharged Daimler V8 is very luxurious, it only does 17 mpg!

All,
Got a Mac Classic, swapped non-functional hard drive,
installed RAM, nearly got it working for my 10-year-old. But....
First pass, no sound out. Not speaker, not headphone
connector. Wait, if you hold your ear right up against it, you hear a
*little* bit. Hm.
Second pass, a week or so later, won't boot. Hmm.
Opened it back up, looked over everything ... what's this?
There's some stuff on the digital board. Wonder what could leave an
oily stain, and how it got there in the first place without leaving
tracks on the inside of the case, the CRT, the disk drives, etc.
etc.? Well, won't hurt to clean it off, I thought ... then the penny
dropped and I realized that there were *three* little islands of
gunge, and they were centered on the three groups of what look like
my favorite nemesis .... capacitors!
<gnashing of teeth>
Many q-tips and much isopropanol later, it boots, but it's
still quiet - too quiet - and I have a bad feeling about how long
it'll keep running before I have to clean it again. There's a bit of
corrosion on one lead of the sound chip, but I can still hear a very
very faint edition of the sound it's supposed to make.
The Classic has a surface-mount digital board. The components
I suspect are metal can devices, lots of them with the same marking
(which I neglected to write down) and one different. Each has a tiny
flat plastic-looking isolator or something between it and the logic
board.
1) Is there a preferred solvent I can squirt under those things and
the sound chip that'll pick up capacitor gunge (or whatever it is)
better than Isopropanol? Is the old standby dihydrogen monoxide a
good bet? (I have plenty of that.)
2) If (sigh. When) I have to pull those things off, I will need a
hot-air soldering station, correct? My thought is, cut up an aluminum
can to make an air dam isolating the cap. from the rest of the board,
then blast it with hot air until it flies off or vaporizes. Is that
close to right?
3) How do I get replacements, and how do I slap those back down on
the board? Is the code on the top all I need to order more?
Hints appreciated.
Hm. Come to think, maybe I better double-check that the
swapped-out hard drive was really dead. The SCSI port might have been
the first casualty of the capacitor scourge.

Chris,
I have the monitor listing (v 2.1) for the SDK-85 in digital form if it
will help.
I've modified it to compile with Pseudo Sam by removing the macros.
I've added line drivers (75188 and 75189) to my SDK-85 to support
RS-232C and changed the code so it runs at 9600 baud.
If you can rustle up an 8755 you could burn the monitor to it.
Regards,
Carl

Hi,
Sorry about my first email. It was late and my back was killing me. I would appreciate very
much if I could some how get a copy of the manual for my 200 in one project kit. I am
60 yrs of age and disabled and have time on my hands.? I graduated in electronics,
head of the class, but I still like basic things... like this kit.
?
??? Sincerely,
????????????????? Bruce Holland

I actually hope he doesn't do "a Space Shuttle replacement".
The Space Shuttle is a classic example of scope creep. It had to do everything. In the end it did do most all of everything, and it did it each of them pretty well, but it was much more complicated than needed for any one task, and schedules and budgets were blown out of the water. But excepting schedules and budgets... it did surprisingly well.
What Burt Rutan could do, is a family of replacements, each of which does one of the shuttle's tasks well. Some stages/assemblies/technologies would probably end up being shared and that's great.
Tim.

Hi Roger,
I'll mull that over, Gatwick is over an hour away. I guess it depends if you go clockwise or anti-clockwise around the M25 (or through the middle of London).
My main classic computer is too big to take (Needs a couple of tail lift lorries and 3 months to re-assemble).

Holy crap, that is a lot of lights. I think that may be more lights than
on all the machines I have put together... Does it display every register
in the machine? How big is the cable that carries all those signals???

I am still after an Elliott paper tape reader head, preferably 1000cps but the 300cps would be acceptable.
I have a Creed 7E which is a 5 bit teleprinter. The covers are missing and I have not tried powering it up yet. Someone has attached a DIN audio type plug to it, and a friend suggested maybe it had been connected up to a BBC micro.
Anyone want to do a trade, either barter or for cash on either of these. I expect to be going to VCF England or whatever its called.
I am in the UK, in the Low Weald of Kent to be more specific.

Seconded. Most useful post I've seen in weeks. Where do I send
contributions? Assuming we can make this a zero-sum game (go vs. not
go) for Tony's finances, I'd like to do that.
