Here's the list of people who've contacted me so far requesting
CDP-1802s from my stash (in order received):
Dave McGuire
Alex Knight
Pete Turnbull
Ethan Dicks
Mike Haas
for a total of 24 parts. I hope I haven't missed anybody.
I think I'll keep about 5 of the original 62. So there would be
about 33 still unspoken for.
I couldn't stand it anymore yesterday afternoon, and went to my
folks' place to dig them out and ended up hauling home a ton of old
computer junk that I already don't have room for in my basement. But my
dad, being as much of a pack rat as I am, was glad to have more space
for his antique engines.
It turns out that I didn't "RC", and they're in the plastic package
instead of ceramic. Most of them are CDP-1802BCE, but some are
CDP-1802CE. I'm sure there's some joke in there about how old these
things are, but I'll leave the actual punch line as an exercise for the
reader. I rediscovered an RCA databook that I found some time after the
original haul, and have almost forgotten about already, that has info on
the whole CDP-18XX range, plus some development systems, including the
COSMAC Microboard Computer Systems. I haven't looked too closely, but
>from a cursory glance, it would appear that it has complete schematics
for all kinds of boards for this system, from the CPU board to RAM, ROM,
battery-backed RAM, UART, display, D/A, and so on. It truly inspires
awe.
Anyway, the CDP-1802CE is listed, but the BCE isn't. The 1802CE is
for temperatures ranging from -40 - +85 deg. C. The 'C' suffix (infix?)
has a "recommended voltage range" of 4-6.5 volts. The 1802 ranges from
4-10.5 volts. The 'E' suffix specifies the plastic case, while 'D'
would be ceramic. But I can't tell from the documentation I have what
the 'B' infix would do to it. Tonight I'll sort them into BCE and CE
and post exactly how many of each I have.

So you actually have a distribution of RT V02? I'd like to get a
copy from you for my archives.
Anyway, maybe what we need is a copy of the boot blocks for various
devices so that they can simply be layed down in the disk image
(using a very simple program) on block 0.
Actually, I think it might be a little difficult with a version
of RT that old, simply because the split between the monitor and
the device drivers had not yet been made, so you had to build a
monitor which included the devices you wanted it to have, and built
to boot using a specific handler. This was back in the days of
DXMNFB
and RKMNFB
which were the monitors for RT-11 FB on an RX01 and RT-11 FB on
an RK05, respectively.

ok, slightly OT. Transferring the os was a snap since the emulator
will read my 11/83's RX33s directly. But since RT11v02 does not
recognize the rx33 I could only transfer the files and have not
been able to bootstrap the emulated rk05.
putr.com's boot command seems to work only with post-version2 os's,
and the e11 docs don't seem to cover this. Perhaps e11 wont do ver 2?
I suppose I could try to locate a 8" drive to strap onto the pc (to
boot one of my rx01s)
This is my first try with e11 so don't know all the ins-outs yet.
Anyone tried rt-v02 on this emulator? Any hints would be appreciated
thanks..... nick

Nazi facist bastards! I'll bet there's a *conspiracy* at work here!
(Where's Fox Mulder when you need him?)
These assholes even claim that:
"TeleDisk was developed to assist the U. S. Treasury Department
in the processing of computer evidence tied to floppy diskettes."
Does anybody know if this is *true*?! I always thought it was
developed to distribute software via BBS's (and other electonic
means).
Rrrrrrrr. Now I'm pissed.

Apparently it was OK. Actually, they were CCI small pistol primers which
are a little more sensitive than Winchester ones, but I used a little
poetic license because I thought more people would realise what I meant.
>From what my friend Mick tells me, some of them went off as they hit the
metal innards of the vacuum (rather than the brushes). I believe it was a
pretty noisy operation, though!
Richard mentioned that Winchester primers come in a flat plastic block; CCI
ones come in a small subdivided tray, about half the size of the Winchester
one. They're not individually compartmentalised like the Winchester ones
and tend to fall out rather easily. Mick had already dropped most of them
on the floor once, and picked them all up by hand. When he did it a second
time he just decided that the vacuum cleaner provided an easier solution.
For those who've not seen them, a tray of primers is about 2" square, and
holds 100 small round objects, 0.17" in diameter.

Ow! I'm surprised the round went off, though.

That said, I could use a couple Mac monitor cables if anybody gets these.

It is for a Gas or liquid Chromatrograph. It communicates to the GC via
HPIL. ( Serial 2 wire loop)
Most have been replaced with PC based data systems.

Well, I'm not saying I'm looking for it for a reasearch project, but I'd
definetly love a scanmaster, also need a system/34... system/88 would be
nice, as would an 8130, 3790, or a 7171..

ObAOL: Me Too. Seriously, I thought the idea was to be able to copy a
diskette to an image file that could be transferred via other means
and then copied back to a diskette for use at the receiving end. The
image file was mostly opaque to the user(s). I'm not sure how this
helps the Treasury Department, unless they're using it to ship
evidence-diskette images back to an FBI agent in the J. Edgar Hoover
building who knows how to work the FBI's one copy of XenoCopy to go
trawling through the reconstitued diskette for files.
I have dim memories from Lasnerian times of netnews articles posted by
and in response to people trying to exchange RX50 images via Teledisk;
the observation made was that doing this required certain versions of
Teledisk and/or certain types of floppy drives.
And I think that all this angst is amusing in light of today's
"Rhymes With Orange" comic strip.
If you want to see the strip in your gooey webulator, wait two weeks,
it'll be up at <http://www.rhymeswithorange.com/>. Those of us who
get it with our newspaper's comics page can have immediate
gratification.
Oh, all right, I'll spoil it. The punch line is "Except for
computers, which no longer read floppy disks." Perhaps the author is
one of those people who thinks "computer" means "Macintosh, late
model".
