Hi,
We seem to have a semi-dead Ultra1 here. Although Sol9 seems to work
OK, it refuses to talk to the Ethernet (a crosscable connected to a
Win box.) Cabling and such is fine, as is Win box- this works on
other amchines, just not the U1.
I am beginning to suspect the U1 is trying to talk through its AUI
port, rather than the UTP. Any OpenBoot commands or switches that I
need be aware of?
Thanks,
Fred

Never mind, I figured it out. Found out that Apple doesn't know how to
make power cords but HP does :-)

Since this is another of my shameless plugs, I'll keep it short. I've posted an HP-41C calculator, a bunch of MicroVAX II boards, and some other goodies on E-pay. Do a search by seller for 'bftbell' (sans quotes) if you're interested.
Thanks much.

The Thunderbirds is another shining example of TV that amazes me that I
used to love. Heck I had a bunch of toys from that show (I think it was
Matchbox that put out a line of "cars" from the show)
Although nothing has yet to beat the Smurfs... I watched an episode of
that the other day on Cartoon Network, and I'm convinced that my parents
used to feed me crack... that's the only explanation I can come up with
as to why I used to wake up early on a Saturday morning and excitedly
watch those little blue idiots!

Many of you have already heard of the SBC6120, our single board
PDP-8/E clone that you can build from a kit. The SBC6120 now has
a complete lights and switches front panel, and the entire assembly,
including a hard disk drive, is about 9" by 15" and 2 1/2" thick and
can be framed and hung on the wall like a painting.
You can see a photo of Debee with one at
http://www.sparetimegizmos.com/Hardware/images/Debee%20and%20FP6120.jpg
Everything is fully functional; all the lights and switches work
as you'd expect and the SBC6120 is able to run most PDP-8 software
including FOCAL and OS/8. You can read all about it on our web site
at
http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm
and
http://www.sparetimegizmos.com/Hardware/SBC6120_Front_Panel.htm
The entire project is open source, and you can download everything
there is to know about the SBC6120 and front panel, including manuals,
schematics, and firmware source code, from
http://www.sparetimegizmos.com/Download.htm
If you like what you see then you can have one for your own wall,
and we'd be happy to sell you a kit of parts to help you build one.

No, they don't, and if you try it, you may destroy them. They're
high-speed (usually 35ns, but the suffix -35, -40, or -45 gives the
actual number) 4k x 8 UV-erasable EPROMs, and to get the speed they use
a different cell construction and a different programming technique.
The bits in an erased device are "undefined" and whether you want a
'1' or a '0' you have to program the actual value. Pinout is pretty
much the same as a 2732 except that pin 20 is /CS1 instead of /OE, and
pin 18 is CS2 (active high) instead of /CE.
My ICT data book doesn't give the programming algorithm, which is
obviously proprietary. It just says contact ICT or use a DATA I/O
Model 29B with Unipak 2 or 2B firmware version V15.
Oh, and like every other EPROM manufacturer I know, ICT say that
exposing it to UV for longer than necessary will affect reliability,
shorten the life, or in extreme cases, destroy the device, so don't
expose them to a UV eraser (standard 12mW/sq.cm) for more than 20
minutes. Overnight is a bad idea!

I was just able to obtain two IBM 6580 Displaywriters. I think they came out around 1980. They came with the dual 8" floppy disk drives and keyboards, but no monitors. The units are 6580s, the drives are 6360s, and keyboards are 630X-91-xxxxxxxxx. These are big heavy units. I'm not big on old IBM equipment so will consider offers of a new home for these units. Contact me for additional information on these units. I'm located in Colo. Springs.

We'll be in Kansas City over a weekend in the near future. Are there any
good surplus stores, museums, geek toy stores, etc, that we should be sure
to visit? Suggestions appreciated!
Found this today. Anybody know anything about it? I tried to search the
net for info but got too much clutter (everybody is putting "preview" in
their ads!) It's a full length 8 bit ISA card and has a DB-9F and
D(something)-25F connector on the slot cover. Besides all the TTL glue
chips, it has eight 4264 (64k x 1?) memories and a HD46505SP-2 (CRT
Controller)(6845 equivilent?) LSIC and a 2732 EPROM on it.

Found this today and thought it was some kind of video card. Bought it and
brought it hame and checked the net
<http://www.mandrake.demon.co.uk/Apple/ltalk/pc_hardware.html> and found
that it's an AppleTalk card for a PC. PN 630-5306-(blank). Anybody need it?
