I tried archiving the FTP site a while back, but it always failed at
about the same point. It almost seemed to me they were cutting off my
access to avoid having people siphon out all the images.

All:
Does anyone have a local mirror (or maybe an ISO or Torrent) of the
Apple II/Asimov archive that I can grab? I find it difficult to capture the
"disk images" directory without timeouts and other delays causing problems.
Thanks.

/************************************************************/
Found a Japanese game diskette for use in the Nintendo Famicom external disk
drive unit. I could only find one disk in a clear carrying case. The game
is called ZANAC and from the pic's looks like a aircraft shoot-up game.
Also at another thrift today I found 4 game cartridges for the Super
Famicom. I'm still looking for a power supply for the Super Famicom console
I got from this same thrift last year.
While digging through a pile of PCs headed for the recycling/re-use
center, I found a couple neat items. One is a NEC Advanced Personal
Computer. Or at least I'm pretty sure that's what it said on the front.
It's an all-in-one case, dual 8" floppy drives mounted vertically on the
right side. Beige case, black trim. And the Keyboard to go with it. Is
this thing worth saving for a museum or something? Free, pickup in New
Haven, CT.
Also was in the pile, and IBM server type item. Small, about the size
of 2 Thinkpads stacked on top of each other. Has 3 1/2' floppy, twin-ax
connections on the back. Didn't notice any console (key/mouse/monitor)
connections on the back. And I believe there is a terminal server under
that also. Any interest? Free, pickup in New Haven, CT.

If I remember correctly 8/A's had a single backplane so using two 5V supplies
will be difficult unless they are specially designed for current sharing.
Otherwise one will try to take the entire load.
Also I think the 8/A is a switching supply. You should check to see if it
will be happy with 5V unloaded.
I would recommend measuring the current draw on the 5V supply. If you
aren't near it then I would see if the fault can be fixed. If you are at
capacity then using a single 5V supply with sufficient capacity should help.
If thei internal 5V can't be unloaded you will need a more complicated current
sharing booster supply or a dummy load on the 5V.
I had that problem with my fully loaded 8/E using more than the rated 5V
current. It had two backplanes without the 5V connected between them. I
powered one half with the existing supply and the other with a modern supply.
It did seem to be mostly PC stuff and rackmount
servers, neither of which interest me particularly. I
was there from about 11.00am onwards. However there
were some other bits and pieces buried in amongst the
new stuff.
Was it me or was there a really *bad* smell in the air
? Anyway in spite of the smell I came away with quite
a bit of gear. I have questions on these items which I
will post separately.
DEC Professional 350 ? no monitor or keyboard. When I
inspected the unit at home I noticed the screws from
the PSU cover are missing so I hope that doesn?t mean
someone has been interfering with it. The unit is
otherwise complete and appears to contain an RD51
drive (10MB) and the monochrome graphics option. I
haven't tried powering it up yet - the missing screws
on the PSU cover bother me enough that I want to poke
around at it first before applying power.
HP-9134A 5MB disc unit. These things are ancient. I
have been looking for something like this to replace
my HP7908 which is still languishing in the corner
with power supply problems.
Charles River Data Systems Universe/68 computer,
badged as a Datapoint system. This is about the size
of a MicroPDP-11/73 (perhaps a little fatter). In
addition to the CRDS Universe subrack, the chassis
houses a lot of terminal I/O ports and an 8? floppy
drive on the front. There?s a SASI interface connector
on the back for mass storage.
Zia Tech ZT 488 GPIB Analyzer. I have had a CS/80 disc
emulator project for Linux on my to-do list for some
time. Perhaps this will get me moving on it.
A couple of ?? tapes for my 9-track drive. Always
useful.
Books ? a couple of National databooks from the mid
70?s; a 1970 System/360 JCL book; a book about
repairing music synthesizers and a Springer-Verlag
publication ?Computer Architecture?, 1975.
I passed on two Televideo 925 keyboards. I also
passed on what appeared to be an IC test system. It
had dozens of test cards corresponding to DTL/TTL
devices of yesteryear, and a test slot where you'd
presumably drop in the test chip. Looked like fine but
was rather large. I forget who the manufacturer was.
Regards,
Dave

Hello fellow ClassicCmp'ers,
Would any of you happen to have the load image for the VT1300 X terminal?
VT1300 is actually a diskless VAXstation 3100 (SCSI controller daughterboard
also omitted) that instead of running VMS or Ultrix netboots a special
image that turns it into the VT1300 X terminal. I'm looking for that
image.
I have the boot images for the VXT 2000 X terminal (VXT and VXT EX software
V2.1) which also support VS3100/VT1300 (I guess it was officially supported
as a software upgrade from VT1300 to VXT 2000), but VXT software on VS3100/
VT1300 does not actually work too well. The VS3100/VT1300 is just a
standard VAXstation while the VXT 2000 has some special hardware and console
ROM adaptations to perform its special function. VS3100/VT1300 has just the
minimal NVRAM used by the console ROM, whereas VXT 2000 has a much larger
NVRAM that can store an entire X resource file. The VXT software is
designed to use that NVRAM and works poorly when it is not available, as is
the case on VS3100/VT1300.
The result is that when you run VXT software on a VS3100/VT1300 and don't
have an InfoServer, there is no way to save customizations to the terminal's
configuration, not even the most essential settings like the DNS servers
(which it does NOT take from the BOOTP server's response), which makes the
terminal practically unusable. On paper VXT software supports three types
of saved settings (resource files): NVRAM, InfoServer-based and host-based.
NVRAM is not an option because it does not exist on VS3100/VT1300,
InfoServer-based is not an option when you don't have an InfoServer, and
apparently for it to fetch a host-based resource file via TFTP it has to
first get the path to it from NVRAM, which is a chicken and egg problem
when you don't have NVRAM.
There is also the much more basic VXT EX software (just an X terminal
without local clients) and it apparently does not use resource files like
the full VXT does, but it still wants to save some things in NVRAM:
again the DNS server (which it stupidly does not take from BOOTP), the
host to connect (XDMCP) to, and the TFTP font path. It's a royal pain
to reenter all that stuff every time, and not just on power cycles, but
every time you log out you have to reenter it before you can log in again
because it restarts and clears everything after XDM ends the session.
I'm hoping to have a better lot with VT1300 software if I can find it,
since it's a bare-bones X server just like VXT EX, but actually designed
for VS3100/VT1300 hardware without NVRAM. From what I've read about it,
it always XDMCPs to the boot host (the one that replied to BOOTP) instead
of doing the song and dance that VXT EX does.
So, does anyone have a copy of the VXT EX load image? TIA for any help,
MS
Thanks for the help Steve. How something simple like a
printer ? I have two HPIB printers, one a full-size HP
line printer and the other a 2225 ThinkJet. Having
either printer hooked up to Linux would actually be
quite useful.

Last week, I brought home my very own 160-A. Complete with the 161
typewriter unit and a bunch of spares. I had to move it about 300 miles
using a garbage (U-Haul) truck.
Put it in the garage, powered it up and it ran! Keyed in a couple of
simple memory tests and an adder test. All passed. It was a great day.
The 161 typewriter is very very rough. Lots of work to be done here.
Heavy rust on the chassis, formica separating from the top, etc. Has
anybody on the list had any experience on repainting these old chasses?
I'm talking to some body shops, but would like to find a specialty
paint within driving distance of Silicon Valley.
Any suggestions?
I took some pictures of the move, but don't have a place to post them.
It's going to be a fun summer.
