BASF 8" floppy drive documentation and alignment

by anders＠abc80.net

Hi, I'm looking after some documentation on the BASF 6104 8" floppy drive. I really want to know how to align it properly. I do not have a 8" alignment disc, can it be done without one? /Anders

Introduction and Novell UnixWare 2.02 problem

by tmanos＠concursive.com

Hi, I'm new to this list, but I've been on the rescue and geeks list for many years. I'm kind of a Unix guy, but unlike many of you, I learned mostly on AT&T Unix. I started using Unix in the early '80s and ran a public access Unix system from roughly '87 to '92, when it turned into a real ISP, which got to be quite large. We mostly used Dec Alpha stuff then. I couldn't afford a Sun workstation in the '80s, so ran SVR2/3/4 on Intel hardware, and even that was expensive. These were the days of 1200bps Smartmodems (which were also pricey) and terminal or BBS interfaces. The Unix systems provided Usenet, real email and even rudimentary file transfer via UUCP. I still love the terminal based interface and won't run X on my old hardware. I'm really a Unix Philosophy sort of guy. Small tools, filters, and all the rest. So, on to my question: I run UnixWare 2.02 on a couple of older machines here at home. It is a pretty standard version of SVR4 if you don't install the Netware stuff. It is very stable and runs great on the older Pentium hardware I have. Recently I build a dual processor P3 system with an ASUS P2B-D MB so I could run SVR4-MP, which runs wonderfully. These are SCSI systems with SCSI2SD boards used as disk drives. Old 50 pin SCSI drives are getting more expensive and have questionable longevity. I want to build some emergency rescue diskettes and tapes, and my problem is that the 3.5" floppy will not format a diskette under UnixWare. I've tried everything I can think of. The drive is good (I can format a DOS floppy when I boot up DOS), and the diskettes are known good. When I use the format command on the raw disk device, I get the following: # /usr/sbin/format -V /dev/rdsk/f03dt formatting. UX:format: ERROR: Formatted 0 out of 160 tracks: Failed in write/read/compare verification on track 0. Doing so without the -V verification just appears to merrily format the diskette, but it's not formatted. The device(s) I'm using are: crw-rw-rw- 5 root sys 1,112 Feb 14 1995 /dev/rdsk/f03ht or crw-rw-rw- 5 root sys 1,112 Feb 14 1995 /dev/rdsk/f03h Both yield the same error. I'm thinking this must be a device driver problem, but i"m out of my league here. Anybody have an idea what's going on and how to fix it? Oh, and sorry for the long post. I thought it might be polite to introduce myself. TIA, Tom

Sticking a VT100 Keyboard Foot Back On

by robert.jarratt＠ntlworld.com

The rubber feet on my VT100 keyboards are falling off. The feet are in good condition, just the glue seems to be failing. Does anyone know what kind of glue should be used to stick them back on reliably? Thanks Rob

for sale/trade: big list of both old and (relatively) new, deadline: end of November (ideally)

by mgariboldi＠gmail.com

The following is for sale, or trade possibly. Most of the listed items I've used together with SGI IRIX and HP/Compaq/DEC OpenVMS and Digital/Tru64 UNIX systems and served me very well. I need to sell this by the end of the month (Nov-2016), else I'll have to potentially scrap a considerable bunch of it. I probably forgot to mention a number of things and perhaps I made a few mistakes here and there. I'll try to update (and if needed, correct) this list with follow-up posts. For now, this is the list of items: - SGI systems, e.g. MIPS R5000 and R5200 processor equipped O2s notably, perhaps also a teal Indigo? with 250-MHz R4400, at least 256 Mbytes (also up to 1 Gbyte available) of RAM, various types of CPUs available, along with various other options in terms of disks, video I/O, etc. (ask me) --> suggestion: if you don't care for IRIX, an O2 would still make an excellent X terminal to any e.g. other system, too, as they don't consume a lot of power and they're wonderfully small; - SGI parts, like an SGI Tezro dual-processor 700-MHz R16000 system board and an SGI DMediaPro DM10 IEEE-1394a FireWire PCI card plus cable and manual; - DEC Multia/UDB VX40B, maximized, with 166-MHz LCA4/21066 processor, the maximum amount of RAM (256 Mbytes), large 73.4-Gbyte 2?" SCSI HDD (with Tru64 UNIX V5.1B[-5?] optionally pre-installed, OpenVMS V7.2 also works on it, the original vertical stand and documents are present, too), Ensoniq AudioPCI (16-bit 48-KHz) audio card, replacement NVRAM/TOY back-up battery, experimental SRM console, PCI audio card and custom-shoehorned, etc.; - various older/non-x86 or compatible computer (besides earlier mentioned SGI, e.g. DEC, Compaq and HP) bits & parts, think of FireWire (e.g. IEEE-1394a), audio, etc. cards, cables and such ... included are things like an AlphaServer DS15-compatible PCI audio card, HP IEEE-1394a FireWire PCI card (rare, should work in some HP Integrity systems) and more (ask me for details); - Exar/Neterion/S2io 10-Gbit fiber-optical (10GBASE-SR) PCI-X Ethernet NICs including transceivers, besides x86/-64 also OpenVMS and IRIX compatible (and tried/used in various systems, including HP rx2600s, rx2620s and a DS15 and also an SGI Tezro), LC FC cables optionally available, too; - Mellanox 40-Gbit InfiniBand PCI-E adapters (3 total), optional copper and fiber-optical cables, in various lengths, are also available; - various (e.g. HP) HBAs, notably SCSI (e.g. Ultra160 and Ultra320) and FC (e.g. 2-Gbit and 4-Gbit), for PCI/-X or PCI-E, many PCI/-X cards also compatible with IRIX and even OpenVMS, some include the HP-branded "combo" types, providing both dual-channel FC (HBA) and Ethernet (NIC); - various optical/tape drives and media (e.g. DVD-RAM, various data & cleaning tapes, of which many brand new), DDS/DAT of many types (e.g. DDS-2/DAT12, DDS-3/DAT24, DDS-4/DAT40 and DDS-5/DAT72) Ultrium (mostly LTO-1 and LTO-3), mostly of brands like HP (notably), Quantum and Sony... to summarize several: -- HP Ultrium LTO-3 SCSI half-height tape drives -- Quantum Ultrium LTO-1 SCSI full-height tape drive -- various Ultrium LTO-3, -2 and -1 cleaning and data cartridge tapes (mostly HP-branded) -- various (HP and Sony-branded) DDS-4/DAT40 tape drives, also one DDS-5/DAT72 drive, all with -- various DDS-5/DAT72, DDS-4/DAT40, DDS-3/DAT24, DDS-2/DAT12 and DDS-1/DAT8 tapes; - various DVD-RAM discs, both with and without the plastic caddies; - various HP, AXUS and Ciprico brand Ultra320 SCSI/S-ATA-bridged & 2-Gbit or 4-Gbit FC external enclosures, for HDDs (optionally including large capacity HDDs, also hardware RAID functionality depending per enclosure), 5?" devices and more (these can be tricky to ship, but not impossible), to summarize some of it: -- AXUS Demon SA-16U4P Ultra320 SCSI<=>S-ATA RAID storage enclosure, including 16 * 1-Tbyte S-ATA HDDs and spares --> advantages: relative low power consumption and triple-redundant power -- Ciprico/Huge Systems MediaVault 4-Gbit FC/FC-AL RAID disk array, including transceivers, 10 * 250-Gbyte P-ATA HDDs plus one or more spare HDDs --> advantages: low power consumption and rather silent -- HP StorageWorks M5313A FC/FC-AL 2-Gbit (JBOD) disk array, including transceivers and 14 * 146.8-Gbyte FC HDDs and one or two spare HDDs, too --> note: perhaps not useful for OpenVMS users as-is, as JBOD and FC-AL are a no-go, but it can be used in a larger SAN setup; - various types of printed documents/documentation (various manuals and reference guides, from e.g. SGI and Intel); - APC Smart-UPS 3000 XLM (heavy-duty, 3000VA capacity) UPS back-up battery aggregate power system, plus special APC RJ-45 USB cable (the whole unit is perhaps hard to ship, but not impossible I guess), this UPS can sustain e.g. several 2U and even some 4U HP Integrity servers for up to 30~40 minutes (depending on the loads, of course); - HP OpenVMS Alpha V8.4 SPL (Software Product Library) July 2010, including the original box and 'documents'; - lots of relatively recent 300-Gbyte and 146.8-Gbyte 80-pin (SCA/-2) and 68-pin 10K and some 15K RPM, hot-swap, SCSI HDDs (most are HP-branded); - older <=9-Gbyte SCSI disks, from various vendors, some with (e.g. DEC) firmware, with 50-, 68- and 80-pin (SCA/-2) connectors (many DEC and Compaq/HP-branded ones, relevant for OpenVMS and Digital/Tru64 UNIX, too); - HP StorageWorks 3U external 5?" SCSI expansion enclosure, room for 4 (68-pin) SCSI devices (including optical drives, tape drives and including full-height models); - PCMCIA and PC card items: SanDisk CompactFlash card reader, SIIG IEEE-1394a adapter, USB 2.0 adapter and an Adaptec Fast SCSI adapter plus cable; - Apple ADB and serial items: Griffin iMate adapters (2 total, 1 in original packaging) and Keyspan adapter; - Chieftec SNT-3141 S-ATA HDD backplane plus sleds and I can provide 3 * free 250-Gbyte S-ATA HDDs --> suggestion: perhaps useful for in a system like the HP zx2000 (if it fits, of course; I never tried it); - IBM System x central fan tray (P/N: 90P4618, FRU P/N: 26K4761) and also (e.g.) x346 rack rails (might fit on other devices/systems, too), SCSI HDD caddies, fans and more (ask me); - HP KVMIP console (PN 262589-821) 8-port extender hub, no power supply required for this; - Gefen 1080p HDMI scaler, professional grade (original box present), useful for some computers and monitors to correct aspect ratios; - non-computer items, or indirectly: professional SDI equipment, like JVC-branded CRT and LCD monitors, Miranda bridges (including for IEEE-1394a FireWire to SDI) and more, also many cables of various lengths available and also photo & video equipment (e.g. Nikon D70 plus Nikon Nikkor AF-S 18-70mm f/1:3.5-4.5G zoom lens, a barely used Sony HDR-FX1000/E plus accessories and various bits & parts and a Tamron TV Zoom Lens 12.5-75mm f/1.8 with C mount with constant aperture over the zoom range). All the items are located in the Netherlands. I'll provide more information and pictures on demand. As far as possible trades go. I'm mostly interested in lenses (mostly in Nikon F/G, Pentax K, Leica M, Leica M39, M42 and Sony E-Mount mounts), in particular fast longer telephoto lenses (135mm and above), also enlarger lenses. - MG

SGI Indigo, WTB Power supply? Burning smell?

by ethan＠757.org

Okay, after a ton of rounding up the parts I finally have the keyboard, keyboard cable, mouse, Indigo and 13W3 to VGA cable to try to bring my Indigo back up. I put my baby on the desk, cable it all up... and burning smell when I start it up. So far I can't find anything on the PCBs that looks burned. Everything smells somewhere between old and burned, so that isn't much help. But here is where it gets crazier. I originally had a R3000 Indigo, with Entry graphics as I recall. Or maybe it had some 3d ass, but it was still 8bit color depth. At some point in the NASA Auctions I had come across another Indigo that worked, and it had a R4K cpu board. And then I had a card that went into one of the desksides that had a Elan set that got you Elan on a deskside (I think.) I left one of the Indigos outside with a bunch of computers for craigslisters to come curbcycle, but a homeless guy stole it all took all the metal and left behind all the smashed up plastic parts (yay.) I couldn't remember what was in the Indigo I left outside. After sniffing the PCBs for a minute or so like bomb dog looking for a burned resistor or cap.... I got to thinking that the PCBs are bigger than I remembered. Better than I remembered. I google the part numbers, and low and behold it's a R4K CPU card and a Elan graphics set. Good for performance, but it's not 100% my first SGI. But still. BUTTTTTTTT.... there is a different power supply for R4K machines, that is different from R3K machines. I'm pretty sure the machine I have is my old trusty Eggbert, and it has a R3K PSU. So now I need to find (this should be easy?) a R4K power supply for an Indigo. I don't even know if the boards will work, green LED came on for a bit then went orange. There was frame buffer output. There was no startup sound that I knew and loved. The 9430810 is the R3000 power supply, the 9430812 is the R4000/R4400 PSU. Any leads? -- Ethan O'Toole

Flex Disc options for the HP 9825

by cruff＠ruffspot.net

Excellent news! I eagerly look forward to this so I can get my 9825T talking to my 9895A! If you spin a PC board, I will be willing to purchase one or two if you end up with extras or are willing to coordinate an order.

Flex Disc options for the HP 9825

by curiousmarc3＠gmail.com

Probably a question for Tony's encyclopedic knowledge. I just scored two HP 9825, one a later "T" option and one "B" version with all the fixings (i.e ROM packs). They both seem to work save the usual tape drive which I have not gotten to yet. Both have the flexible disc ROM. What kind of discs can I hook up? I think the HP 9895 8" floppy would work. What about the HP 82901 5.25" floppy drive? How do I read/write program files from the disc interface? Marc Sent from my iPad

It's cheaply bought on Ebay, I'd just get a parts unit there. That said, the fan could be the source of the smell and the part to go first from my limited experience when a fan dies is the video card. Bill Degnan twitter: billdeg vintagecomputer.net
