Asimov mirror?

by rcini＠optonline.net

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.

Goodwill find from Nintendo

by jrkeys＠concentric.net

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.

NEC "Advanced Personal Computer"?

by woyciesjes＠sbcglobal.net

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. -- --- Dave Woyciesjes --- ICQ# 905818

Help ID this operating system?

by vcf＠siconic.com

I'm trying to determine what the operating system is of some 8" floppies I'm trying to read. I found the directory on track 2 but it's not CP/M, and it's not DOS. It looks CP/M-ish, but the offsets of the file entries are not right. Anadisk says this is a high density disk, sector IDs 1-26 on side 0 and 27-52 on side 1, 256 byte sectors. I see this string in the first track: Type <CR> to load system. Some extra context around this string: 0000100: 3100 303a 0b00 b7f2 a034 3a8d 4811 363b 1.0:.....4:.H.6; 0000110: 123a 0600 4fcd 30f8 0120 4e0b 78b0 20fb .:..O.0..

PDP8 power supply G8018

by djg＠drs-c4i.com

> I am considering using two modern +5v at 25A switching power supplies to > replace the +5V source ( leaving the original -5V at 2A,+15 at 2A,-15 at 2A,and > +20 at 4A as original) in a PDP-8A. > 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.

TCF goodies

by david_comley＠yahoo.com

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 --- chris <cb at mythtech.net> wrote: > I went to the Trenton Computer Fest today. I didn't > get over to the MARCH > table, sorry.

Looking for VT1300 load image

by msokolov＠ivan.Harhan.ORG

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

HPIB fundamentals (was Questions - Universe/68, HP-9134A, VT420 composite video)

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. -Dave --- Steve Robertson <steerex at mindspring.com> wrote: > Do you have any other HPIB devices?

At Last - A Control Data 160-A!

by bpettit＠ix.netcom.com

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. Billy
