Hello everyone,
My JrCaptain and its power supply (the wall wart) have become separated.
I'm pretty sure I still have it, it's just that I don't know which one
it is. Naturally none have the Tecmar name. I'm sure someone here has
one of these, so would you please look at the wall wart or power brick
and tell me what it says?
Thanks,
Jim

Right. For a pre-Mac II (e.g. Mac Plus), even Appletalk network file
sharing was an exercise in futility, let alone Ethernet. Until the
Quadras came along, an Ethernet interface was not built-in. You had
to buy a separate network card for you Mac II, and more likely than
not, it used "thin ethernet" (coax) not 10-base-T. I did use some 10-
base-T SCSI Ethernet adapters for non-expandable Mac laptops around
1975, but they were barely up-to-snuff.
While I was in grad school, from 1997 through 1999, I used a Quadra
700 running IE for browsing the web. It seemed unbearably slow even
then, and I think I switched to Netscape because its rendering engine
was more efficient (IE often had to redraw the whole web page twice--
e.g. to figure out how big the images were, and on a 68040 that was a
noticeable delay). Plus a lots of things have changed since then. I
don't think I even needed a Flash plugins at the time. Not that you
would even think of watching a YouTube video on a processor that
slow. For email I used GNU emacs RMAIL running on my group's Unix
server. I had to abandon it when MIME became the norm around 2000.
Bottom line: For small values of "access the internet" the older
Macs were serviceable. By modern standards, the old browsers are
curiosities at best. But if you need to transfer some old files off
your old Mac, the connectivity is there, and I have been grateful
that FTP still works even today.

Hello group:
I have a person whom was kind enough to post the PDF excerps from scanning "Practical Microprocessors"
which is the lab manual for the HP 5036 microprocessor trainer..
I scanned the schematics, rom listing and a few other pages.
You can find it on Dave's site here
http://www.neurotica.com/misc/practical_microprocessors.pdf
be warned that in order to make it worth while to read its 125 megs I suggest that you print it out the 40 so pages.
I printed it to make sure that its readable. Spent a day to scan it and build the pdf so I hope those with the trainer
and have no manual will find it usefull.

Before I go hauling all those little Torx screws out (yes Tony I *do*
have proper Torx bits, unlike the last person to be inside it), can
anyone point me in the direction of the CMOS battery?
I bet it's right underneath the monitor, or something.

Hi,
Thanks for the encouraging responses, I'll go and have a read. Someone also kindly emailed me these URLs with further useful info:
http://www.pimpworks.org/ibm/aixled.htmlhttp://www.pimpworks.org/ibm/ledcomm.txt
I have contact with a AIX CD, and I have obtained (a few!) SCSI CD drive that cn be tweaked to the correct sector size.
Couple more questions though:
1. Is there a back-up battery (perhaps in a RTC chip like on a Sparcstation 2), that will have surely failed by 2008.
2. Is there a source to download diagnostic floppy set, I hadn't known about these until today.
Thanks again,
John

You are probably right. Its not like I'm trying to hide anything but I
really don't know much about these. Other than the fact that it powers up
that's about it. Picked it up local with the idea of "wow IMSAI" but
realized it's a bit out of my realm of interest, I'll never actually use it,
and I need the money to go to school this Fall. I'm more than happy to
answer any questions anyone has though.

For a big ticket item, that ad is really lacking in pics and information.
I stumbled on a disturbing thing on Ebay. There's a guy who seems to
specialize in taking apart perfectly good classic computer stuff to sell
the pieces. I found him when looking for a VT100. He's selling a naked
CRT that he says was taken from a working VT180. I asked him why. No
answer.

The first to reply has claimed the MD3. Thanks. I'll have some
