While away, I popped in a car boot sale, and picked up an Apple Mac LC III
base unit for 50p! Never having had anything to do with macs before, and
only having new PC and old BBC kit about, I'm a bit stuck at first base - I
think I have spotted the video out (15 way D-type, and have seen converters
for them!) but where on earth does one connect a keyboard and mouse?
Internally, it seems like it might be complete: 80Mb SCSI hard disc, one
ram stick (one free slot) 68030 processor (and an empty socket next to
it???) is this right?
I also picked up (also for 50p) a compaq slt/286 laptop (missing keyboard
and PSU) and a Mitec 3030D, also missing PSU. As both of course have flat
batteries, I've not poked at them much yet. If they are of interest to
anybody, drop me a line! (collection/shipping at cost from Salford, UK.)

The keyboard and mouse connect to the ADB port, which is a four pin
mini-din that looks the same as an S-Video connector on some A/V
equipment. Here is a good picture of the connector and it's symbol -
http://charm.cs.uiuc.edu/users/olawlor/ref/mac_ports/adb.jpg You'll
need a Macintosh keyboard and mouse. If you want, I have plenty, but
you should have no trouble finding them locally, all Macintosh
computers from the Mac SE all the way up to the beige G3's and G3 AIO's
used the same type of keyboard and mouse. From your description, it
seems to be complete, and there is a VERY good chance it works. Those
critters are really hard to kill. As for a monitor, any older Mac
monitor should work, as should most adapters with a multisync SVGA
monitor. Not all multisync monitors work, however, as the not all can
sync to the proper frequency.

While we are on the subject of Macs, I have a question.
I used to work in the Mac Repair shop at ASU, fixing dead Macs. We used to
get a lot of the old "all in one" (SE, SE/30, Classic, Classic II) Macs in
with bad analog boards (they would make an evil buzzing noise one day, and
then just refuse to work...)
We would fix this by replacing the bad board, as you do, not repairing the
board itself.
My Classic II got left on over the weekend, and was found dead and
buzzing. It needs a new board. I was wondering if anyone knew what
component it was on the analog (or power/sweep) board that causes it to
die, so could fire up my soldering iron and have a go...
...much easier that enplaning to the aforementioned wife why I spent ?30 on
a computer that was free if i would remove it...
Take Care,
mark

I'm not sure about the Classic II, but I know on the other compact
macs, a big problem was C1 on the analog board, and cracked solder
joints on J4 and J1. This generally caused "vertical line disease"
where the display collapses into a vertical line. When the machine
won't turn on and makes a "flup flup flup" noise, then there are
generally more severe problems. T1 could have failed, or an
electrolytic capacitor. Check C3, C24, C25, C26, C29, C30 and C31.
These may be different on the Classic II. I haven't really had to fix
many Classic II's, mostly just the earlier macs (Mac Plus
especially...). Also, just check for obviously burnt parts, bulging
electrolytics and cracked solder joints.

Thanks for the information. I'll take it apart and have a look. Based on
the amount of rust on the port connectors on the logic board, and the rust
on the metal frame around the power switch, it has been exposed to some of
this wonderful British weather...
I'll let you know if it's a cap or something.
Take Care,
Mark

Hmm..I had to pay a quid for mine.

think I have spotted the video out (15 way D-type, and have seen converters
for them!)
Yep, that's it.
but where on earth does one connect a keyboard and
mouse?
The keyboard plugs into the ADB (Apple Desktop Bus) socket. That's the
one with 4 pins and a rectangular slot with a simple diagram of a bus
system under it. The mouse plugs into the keyboard.
Internally, it seems like it might be complete: 80Mb
SCSI hard disc, one
ram stick (one free slot) 68030 processor (and an empty socket next to
it???) is this right?
Sounds about right.

If you'd asked me you could've had one for nowt - I have many spares :)

The ADB port (apple desktop bus?). The symbol for it is a vertical line with
3 dots on it. It's next to the printer port - the one with a little printer
above it.

Yep. The empty socket is for a copro. Beware though that the PRAM battery is
probably dead....if you DO find a monitor for it (and keyboard and mouse),
switch it on and get the 'happy mac' sound but no picture that'll be
what's
up.
