Here's something you do not see every day.
There are four people interested in bringing a variant of PDP-8 to VCF
East next spring (April 17-19).
On the PDP-8 front, so far only David Gesswein is registered; others
will be soon.
It would be very cool if there were LOTS of PDP-8 computers at the show,
in honor of the original Straight-8's 50th anniversary. (We invited
Gordon Bell, who said he's unable to attend that weekend. Darn.)
So: if you've got a PDP-8 of any flavor, and you've always dreamed of
showing it off and/or attending a VCF, now's your chance. Paging all the
California and Boston people!!!! :)
Overall exhibits so far are here:
http://www.vintage.org/2015/east/exhibit.php -- we're expecting 30 or so
by April.
There will also be a dozen or more technical classes on Friday, April
17. So far only one is posted, but we've got most of the others almost
determined, and those will be posted soon.
Keynoters for the weekend are Ted Nelson (Saturday) and Bob Frankston
(Sunday).
I would be grateful for advice on files generated by RS/1, an old BBN software product, about a dozen years ago on a Sun system running Unix.
I don't need to use the software, just to read the contents of a few files. It doesn't matter if the format's a mess. If I can see the numbers, I can work out how to extract the information.
While digging through more old detritus, I came across an Archie-McPhee
catalog and three still in shrinkwrap, "Computer Voodoo" soft
sculptures. Anyone know what the value of such stuff is?

I've got a few knocking about in storage which contain early Linux
distributions. I'm not sure they're particularly rare or unusual, which is why
I haven't bothered to dig them out and make images yet.

archive.org contains a full set of Aminet CDs from 1 through 52 (the first two
being Walnut Creek) and also Aminet Sets 1-3 and 9, and Aminet Games. The first
Aminet CD also seems to contain a mirror of AB20 and can be downloaded via
https://archive.org/details/aminet-walnut-creek-1.
https://archive.org/details/aminet-2 actually contains Aminet 12, and so you'll
be wanting https://archive.org/details/aminet-walnut-creek-2 for Aminet 2. My
physical CD of Aminet 3 has different contents to the version on archive.org,
and although I can see *what* the differences are, I'm unclear on the *why*. My
other handful of Aminet CDs are bitwise identical.
At some point I really should figure out how to provide errata and new uploads
for archive.org.
These do not have a Sun "Type" number on them. Definitely older style.
249-8909 or 370-0109, qty 1, missing 2 switches plus 3 more caps. Has
mouse, 370-1091, which has definitely seen better days!
370-1095, qty 1 complete. No mouse with this one.

Silly question but I might as well ask. Would anyone have the cross compiler
assembler for the HP 85. It was used for the development of the HP-85 ROMs,
and was run on an HP 1000 (I think).

Subject line says it all... From my research this is an oddball cable
with a "DB21W4" connector on one end that breaks out into 4 BNC plus a
keyboard / mouse connector for the lamentable Sun 386i series (with
color video). (Part number 530-1366.) I have acquired one of these
machines and have an odd inclination to make it do something... anyone
have one going spare?
Thanks,

In pouring over the documentation for the 13304A (FAB), I find one thing
unclear. Is there a way to disable a given block? Empirically, it seems that
if you have roms in a given block they are going to get mapped SOMEWHERE,
depending on the jumpers and if you don't have roms in a given block you
don't have to worry about setting jumpers to disable that block. But I was
curious if there was a given jumper combination for a block to disable it -
without having to pull the roms. Not a huge deal, just curious, and I don't
see it in the docs. Any thoughts?
Best,

The terminal controller board on my VT101 is not working, if it displays
anything it is random characters. I have used my scope to check the 8085
CPU. It has power, it is outputting a valid clock, but there is no activity
on the RD,WR and ALE pins. I am guessing the 8085 is bad, but before I go
replacing it I wanted to check if anyone knew of anything else that might
cause the 8085 to misbehave (ie am I seeing symptoms or a cause?).
It looks to be easy to get 8085s, if I replace it I will socket it at the
same time, but would rather avoid having to desolder it if the problem is
elsewhere.
Any advice gratefully received.
Thanks
Rob
PS Just to check that the rest of the terminal works, I substituted the
terminal controller board with one from a VT102 and it worked perfectly. So
the problem is definitely on the terminal controller board.
