To All:
Just in case anyone was interested, here are the schematics that I found
for the Intercept Jr. and two of its accessory boards that were done
about 1975 or 1976. Your's truly drew all three of these on the drawing
board with pencil and straightedge. They were then turned into
publishable versions by a graphic artist. The two boards plus a third
one which had a number "devices" on it for lab demos made up the initial
Intercept Jr. product set. This was used to support the original
education classes that were based around this design.
Still looking for listings of the micro-interpreter. This was the
software that made use of the special keyboard and was embedded in the
mask-programmed IM6312 ROM.
You can see that the serial interface on the PIEART was arranged to
support either an RS-232C interface or the old-fashioned 20ma current
loop for communication with an ASR-33 Teletype.
On the RAM module, the board held a set of two AA batteries to provide
battery back-up on the RAM memory. It may be hard to believe but I do
seem to remember that Intersil actually patented the little circuit in
the upper right hand corner that prevented these batteries from being
back-biased when the regular power was on and kicked them in gracefully
when that power was lost.

Attachments aren't allowed on the list. So, no, it wasn't just you.
Also, don't send the same message to both cctalk and cctech.

The mailinglist seems to drop attachments (at least those exceeding a
certain size), it also appears to reject mails with valid S/MIME signatures.
The mail was sent to Ethan and others in parallel to the list; so
apparently Ethan got the attachment.

I thought this was in the FAQ, but it's not. It has, though, been
explained several times over the years. The mailing list does not allow
attachments, by design, as it's intended for discussion, not filestore,
and presumably most of the (thousands?) of subscribers wouldn't be
interested in any one particular attachment (like schematics). It also
doesn't allow HTML; it's meant to be lightweight.
Maybe someone should volunteer to update the FAQ :-) It could do with a
note about why you shouldn't post to cctech as well as cctalk, for
example. For those who don't already know, it's not two lists, it's two
views of the same list. Unless it's changed recently, messages posted
by cctech subscribers are automatically also sent to cctalk; messages to
cctalk are copied to cctech after a moderation process.

Actually, that is a pretty good idea. The server is well up to the task.
There would have to be a good mechanism to prevent the server becoming a
warez/pr0n dumping grounds from others. And there would have to be a good
way to give files time limits so temp transfers between members don't sit
there forever.
Someone send me a proftpd.conf for it and I'll look it over :)

You could always force uploaders to specify a category and/or description of
every file they upload. An archive link would be even better, but you're not
going to know that until you've uploaded the file and posted the message...

I'd be willing to set something up, but I don't want "people with
questionable
morals" using it to share MP3s and so forth -- ideally I'd want it to be
accessible only by cctalk/cctech members, but IIRC there isn't an easy way to
check that. The best idea I can come up with is to rig up a script that
attempts to log into the Mailman subscription options page (which only
requires an email address) and bomb out if Mailman rejects the email address...

Thanks Jules,
good insight.
In retrospect, the classiccmp server already offers boatloads of ftp space
where new entries would more than likely be stored by the respective site
maintainers.
I think it would be best for the list to just offer a "90 day automatic
delete" ftp site, specifically to address the case where someone posts a
schematic, etc. to the list given that the list doesn't allow it (so that
people aren't forced to dload something they have no interest in). That way
every list member would be able to post a download address for something
mentioned in a post. If one of the many other sites out there (or on the
classiccmp server) want to archive that item before it's deleted, so much
the better.

a chance of being able to find it again if needed.

Seriously though, I run a BBS called The Retro Archive that is available

If there is interest, I'd be happy to set up a special transfer area for

files via that method once they create an account on the BBS.

Hmmm...I just remembered a very ancient (and funny) fact.
Some decades ago, I had two 486' and a 386 networked with lantastic and
personal netware (yes...I was something you can call "rich" as a 16-year-old
boy working repairing computers) and had my own BBS. These were the times,
where it was hard as hell to put more than two modems in the same computer
(I hadn't discovered major bbs yet, I used RA + deskview + QEMM). Since the
computers were tied to my BBS nodes, I wanted to have a CHEAP serial
terminal for a "local sysop" node.
I had a msx with serial port...hmmm...
It was easy :) Opened a DOORWAY session inside deskview and connected
the MSX to the serial port. I was "running MSDOS 5" on MSX, no one
understood how it could be possible hehehehe :oD And this was my permanent
local node. So bad it didn't had ANSI.

I've seen it work the other way around. In the mid-to-late-80's back
in Madison, WI there was an 8 line chat system called "Warlord Chat".
Warlord had built it and written the software himself. The central
system was an IBM PC (ISTR it was a 5150 rather than an XT). It was
"networked" to four Atari 400s. I assume there was a serial
connection from the PC to each Atari. Each of the Ataris ran two
modems.
The competing system in town was called "the Bee Line" which had a
similar capacity, but I think it was built out of Apple II systems.
Of course all the cool people used Warlord Chat.

modems.
What I find most disturbing is that it was **EASY** to put 4 or even 8
modems in each ISA box, and ***EASY*** to program for them. Now I have the
knowledge, but it was pretty hermetic on the past. We live in the age of
info, and now we have the world at our hands...
I'm lucky, I live in one of the best of all ages :o)

Yea, the age of script kiddies who know everything there is to know from
Google.
Warlord had
built it and written the software himself. The central
system was an IBM PC (ISTR it was a 5150 rather than an XT). It was
"networked" to four Atari 400s. I assume there was a serial
connection from the PC to each Atari. Each of the Ataris ran two
modems.

It concerns me. Jay's already providing a
lot of free stuff, and
managing the list. There are hundreds of free binary hosting sites
online, I'd recommend people use those instead.

Hi Jeff,
-------------- Original message from "Jeff Little (jeflittl)" <jeflittl at

Still looking for listings of the micro-interpreter.
This was the
software that made use of the special keyboard and was embedded in the
mask-programmed IM6312 ROM.
My jr is missing that 6312 too. I did get the user manual with mine though and the
monitor listing (and schematics) are in there. I scanned the 6 pages of microinterpreter
listing and loaded them here ( http://stsimonschess.com/iijrom.htm ) Please (somebody)
download and make them available if reneeded, I don't really have much bandwidth
there.
Cheers
- Mike
