Long term publicly accessible backups [Was: Uncorrupted A/UX 3.1 Update]

Seems to me, not that different than Cantor and Siegel's Usenet Spam. As in, it's technically possible to do something, so it's OK to do it. Misusing Usenet, not a good idea. Now posting it to a binary warez newsgroup, I don't see much harm in that. Worst case, somebody might complain that what you're posting is not illegal or a copyright violation and therefore you shouldn't do it. Tim.

HP 8018A heath sink getting hot

by hp-fix＠xs4all.nl

I acquired a HP 8018A serial data generator, a very nice piece of equipment. But after a little time the power supply heath sink is getting hot about 70 degrees Celsius (158F). I'm not sure if that is normal, anyone who can help me with this ? -Rik

Looking for: Sun 3/150 or 4/150

by derschjo＠mail.msu.edu

Title says it all; I'm basically looking for a VME-based Sun workstation with 5 or 6 slots -- something that's a nice middle ground between the cramped 3-slot machines and the huge 12 and 16-slot ones. It doesn't have to be complete or running, but a working power supply would be helpful... I'm trying to find a suitable host for my Symbolics UX400 (a VME-based lisp coprocessor for old Sun machines), and the Sun 3/140 I have doesn't seem to be able to keep the UX400 cool enough (it crashes quite frequently). Anyone (preferably local to Seattle) have something that fits the bill going spare? I can trade a bunch of Sun3 hardware :). - Josh

Still looking for LaserJet lower cassette

by charlesmorris800＠centurytel.net

I'm still trying to locate the "Optional Lower Cassette" for my HP LaserJet IIp+ (that holds 250 sheets of paper and fits underneath the printer (instead of feeding them 20-30 at a time through the front door). Anyone have a "parts" IIp from which I can buy the cassette & paper tray? thanks Charles

Apple A/UX install

by snhirsch＠gmail.com

Anyone on the list have experience installing A/UX on a 68k Mac? I'm running into some very odd issue trying to bring up my Centris 610. The Centris shipped with a 68LC040 processor and I've upgraded to a "full" RC68040 CPU, since that's a requirement for A/UX. The CD-ROM drive is one of the units known to be compatible with A/UX. The FAQ claims that the installer understands third-party hard disks (unlike the MacOS installer) so I'm trying to use (variously) an older IBM Deskstar 850MB and/or Fujitsu 500MB SCSI drive for the install target. Here's the odd part: With the original Apple-branded OEM Quantum drive (which I do not want to overwrite) on the SCSI bus the installer recognizes the CD-ROM and is willing to begin the process. However, with any of the third-party hard drives in the system it is unable to recognize _anything_ on the SCSI bus - doesn't see the hard disk or the CD-ROM. I've checked and double-checked the jumpering on the hard disk and it's not conflicting with the CD-ROM. Both the IBM and Fujitsu are fairly run-of-the-mill 50-pin SCSI units. I've never had issues in the past with non-Apple drives hanging the bus or preventing access to other devices, so this one's really a head-scratcher. Any ideas what might be throwing the SCSI subsystem for a loop? Steve --

preparing an order for more S-100 boards

by lynchaj＠yahoo.com

Hi! I am preparing to order some additional S-100 board PCBs. At the moment, the most requested boards on the waiting list are below S-100 buffered prototyping board (12 waiting) S-100 4MB SRAM (11 waiting) S-100 EPROM (9 waiting) There needs about 20-25 firm builders on the waiting list to make a PCB manufacturing order feasible. I cannot afford a lot of leftover PCBs so it is important that most of these boards have a home before I will place an order. If you would like to get some S-100 PCBs based on the projects we have done already please contact me at LYNCHAJ at YAHOO.COM <mailto:LYNCHAJ at YAHOO.COM?subject=S-100> and I will add you to the waiting list. Please do not sign up if you are uncertain or unwilling to follow through with getting a PCB. Your word of honor is sufficient to me that you will follow through for PCBs on the waiting list. I still have a small number of S-100 parallel ASCII keyboard boards and S-100 PIC/RTC boards. In particular the S-100 PIC/RTC boards will be very important for the upcoming S-100 8086 CPU board John and I are working on. Thanks and have a nice day! Andrew Lynch PS a complete list of completed S-100 boards below. If you are interested in any of these boards please let me know however the number of builders on the waiting list probably means another board order is some time away. Regular Prototyping board Buffered Prototyping board 8 Slot Backplane IDE Parallel ASCII Keyboard converter 4MB SRAM System Monitor Board Bus Extender EPROM IO PIC/RTC Z80 CPU these are in work but not complete yet: Console IO ZFDC 68K CPU 8086 CPU

HP-UX .WAD file format?

by glen.slick＠gmail.com

Anyone here know anything about the .WAD file format in the context of HP-UX 9.0x, or more specifically in the context of an HP 16505A which is logic analyzer application running on top of HP-UX 9.0x on an HP 712/60? I have a set of MS-DOS FAT12 floppy disk images which each contain an UPDATE.WAD and an INFO.WAD file pair. I believe these must be compressed file archives. From looking at hex dumps of the files there are no obvious plain text strings. I would like to be able to view the archive contents and extract whatever files they might contain. Sample hex dumps below. These sample file pairs start with a common 15-byte file header: UPDATE.WAD (file size 320-bytes) 0000:0000 1f9d 9030 6e04 1c08-a320 8c18 060b ca80 ...0n...? ....?. 0000:0010 4123 e08d 1a0c 0fde-40d8 30c6 c484 3016 A#?....?(a)?0??.0. 0000:0020 6284 61a3 c68d 1920-1bda c038 03e2 c684 b.a??.. .??8.??. 0000:0030 75e6 c879 3107 8e9c-3763 d694 a133 e745 u??y1...7c?.?3?E 0000:0040 1937 765e 9849 c3a6-cc99 9775 e0cc 0130 .7v^.I???..u??.0 0000:0050 50a0 c084 0813 ce88-78e3 e149 a524 4f76 P??...?.x??I?$Ov 0000:0060 fc18 9223 4619 1a9f-c248 b9b2 e5cb 9833 ?..#F...?H????.3 0000:0070 6bde b443 d428 4183-490d 366c d8d4 a4d6 k??C?(A.I.6l????
