One of my sources got a new load today. I went by and checked it out and
found a HP 1000 F Series computer. It's been pretty badly beaten up but it
has a full load of cards so I'll probably use it for parts. Also found a
double sized battery backup/power fail battery for a HP 1000.
Also found a weird set of black boxs that appear to be made for aircraft
use. They're all marked Ampex DCRSi. One is marked Transport and has a
large tape drive built in the top of it. The others are marked Recorder,
Reproduce and then a Power Supply. Does anyone know anything about these?
They're very unusual looking.
Also found a pile of NIB Intel AboveBoards for the PC AT, a bunch of
various cards with some interesting ICs that I'll pull and add to the parts
bins, a Tektronix 4041 computer and two Tektronix 4041DDU Disk Drive Units
for the 4041.
But one of the nicest finds was a optical paper tape reader that can be
set to read 5, 6 or 8 level PT. Changing the 5, 6, 8 switch raises and
lowers different sets of guide pins in the reader mechanism and moves the
PT left or right so that it lines up with the drive sprocket. The front
says Data Precision DP203 and the back says Membrain AH30218. There have
been some Membrain computer(?) cards showing up out there so I'm guessing
that this came off of some kind of Membrain computer but was actually made
by DP. Does anyone have any info on it?

Jay,
Just to inform you that I was kicked out of the list, which I've since
resubscribed again. I noted that other long gone ex-list members were
resurrected accidentally too...
Good luck.

Of course, if one auto-archive the ccTech list, then they get (in theory) a good archive of all of the topical information. Interactive reading is done on the ccTalk list.
This technique works good for me, especially if a period of time elapses where I dont have the time to view and make manual decisions on all of the posts...

Jay for the specific post I was mentioning the "To:" field is set to ccTalk at classiccmp.org in BOTH copies. NOT one copy addressed to ccTalk and the other to ccTech.....
I'm looking for the above card. It's the hi-res video card for the
A3000UX (and I think A2500UX) Amigas. As far as I know, it only runs in
Amiga UNIX.
If you have one to trade, sell or give away, let me know off-list,
and how much you want for it. I'm in Austin, Texas, US, ZIP code 78748.

One book that has quite a bit of interesting information on these
machines is "Punched Card Data processing" by Gustave Rath. I lucked out
at the last TRW swap meet and found this along with "Industrial
Calculating Devices" by Wilcox, Butler. The first book is available on
ABE for about $9.00 or so, but the other book is a little more pricey at
around $40.00.

The Hyperion - the first PC portable (narrowly beat Compaq), cuter
and smaller than the Compaq. Notable for it's *low* degree of IBM
compatibility. [Actually it isn't *that* bad, but there are a few
differences which prevent a number of poorly bahaved applications
>from running] - Deserves extra points for choosing an obscure, off-
the wall floppy drive with reliability problems, and molding the
bezel so that other drives could not be easily substituted. These
two factors gave a bad taste to what was otherwise a very nice
little machine.
I'd also add the Portfolio, as the first MS-DOS palmtop, and possibly
the T1000 as one of the earliest successful laptop format PCs.
For strictly personal reasons, and moving away from "IBM PC's", I
would vote for the Nabu 1600 - 8086 based, ran CP/M-86, MS-DOS,
Xenix and eventually QNX, using serial consoles. I had about 1/2
dozen of them at one time, my first machine with a hard drive, and
the first that ran a "real" multi-user system - but almost nobody
has ever heard of them...

Hi
Yes, that's the problem. I found that if one goes into
normal light for a few minutes and then returns to the dark,
you'll see much more color. I used this trick for comets.
Comets are a nice aqua blue color.

Hi
To get a flat field, use a telephoto lens. The farther
away you can get from the unit the better the depth of
focus. It does require a tripod for a good image.
