Have you found any more? I looked for MITS ads in Popular Electronics
>from about 1971 to 1974. They had many calculators, sometimes the last 2 digits
in the model number = calsulator digits. I think the nmost digits I saw was
14, though. Also clocks, etc.
In late 1974 their ads were for a 416 which was a 4 channel x 16 led "logic
scope" Built in one of those black bakelite boxes. It sounds like one of
those oscilloscope "multi-channel" adapters that were popular when CMOS
multiplexers came out, like the 4051, but this one used led's instead of am
external scope.

Hello, all:
Well, this is my first attempt at a Web site. Actually, there's two, at
these URLs:
http://highgate.comm.sfu.ca/~rcini/pdp11/index.html
and
http://highgate.comm.sfu.ca/~rcini/classiccmp/index.html
I found out today looking at the site "live" that certain FrontPage
elements did not translate (such as the hit counter). I'm opening up these
URLs for criticism. Let me know what y'all think.
I also need good links recommendations. I have a few, but I need more.

256k (18bit) is plenty.
A good package is a 11/23, 256kram, DLV11j, RQDX3, BDV11.
That gives you 4 serial ports, full memory without backplane mods,
RX50/RX33 floppy and MSCP hard disk (RDxx) and the BDV terminates
the bus plus supplies some of the desireable boots (no mscp).
using a 11/23b or 11/73 you can remove the BDV11 and they have
mscp boots. however the PS is right on the edge.

Question of the day, how do you go about cleaning an RL02 pack. I'm not
talking about the "Customer" cleaning that the user manual talks about.
I'm talking about the "Dec Certified Tech" six month cleaning or however it
was they put it (read it last night). The six month cleaning sounds like
it includes cleaning inside the pack, which is what I"m interested in. I
know someone, Tony I think, mentioned taking apart and cleaning RK05 packs.
Well that's what I'm wanting to do with this RL02.
It's called the pack is visably dirty inside, with a thin film of grim.
Any suggestions, recommendations, crys of "are you out of your freaking mind"?

Well from (rusty) memory Boston Business Computing (Computers?) had a
version of EDT that ran on PCs. In addition, Digital had a version of eve
that ran under Ultrix and it had EDT emulation. I used the latter approach
for a while but then just got assimilated by the vi cube :-)

Save for your limited to the 1meg of ram (no CD) and the power is
limited. the vt103 was designed as a small system and if you smoke
the PS you may have a time finding another.

Hello out there in classic computer land,
I'm new to the list and wanted to introduce myself and
my Web pages to the rest of ya'll. My name is Alex
Knight and my Web page, the Calculator History and
Technology Archive, is located at:
http://aknight.home.mindspring.com/calc.htm
My interest is primarily in early-model electronic
calculators, but there are some crossover machines that
seem to fit the bill as classic computers, and
in my searching for old calculators I sometimes turn
up some interesting old computer stuff.
One of the more interesting machines that I have written
an article about for my Web site is called a Mathatron, which
was advertised as a desktop calculator/computer and sold as
early as 1964. The Mathatron is a very large and heavy
(24" x 24", 80 lbs) machine, but it will fit on top of
a sturdy desk. I believe it to be the first programmable
calculator, and some other people I've talked to consider
it to be the first desktop computer (because of it's
programmability, available peripherals, etc.). So ya'll
take a look and let me know if you have any additional
info. on this unit that I may be able to add to my article.
Another "crossover" machine that I have a little info
(mainly pictures) of is the HP 9830, called a calculator
but in fact a computer with BASIC.
Also on my Web site is a list of things that I'm looking
for and things I have for trading, as I find classic
computer items that I put on the trading block I'll
send a message to the list to let ya'll know.
Have fun,
Alex Knight

I would have thought so. I don't think there were any features "retired" in
going form 5.2 to 5.5. Of course, there were lots of new things added
although sitting here I can't think of what - it's been a while since 5.5
was released!
