WTT/WTB: SGI Indigo² IMPACT (4 Mbyte) TRAM board

by marcogb＠xs4all.nl

Does anyone have one of these TRAM (Texture Memory, 4 Mbytes ideally, P/N: 030-0676-003) boards, for an SGI Indigo? IMPACT (e.g. for HighIMPACT) graphics card to trade/sell? (See my previous threads for possible items to trade.) Thanks in advance. - MG

FS: 2× Compaq DS10

by marcogb＠xs4all.nl

Two Compaq AlphaServer DS10 systems, each with a 466 MHz EV6 processor and 2 Gbytes RAM (I can also reduce it to, say, 256 Mbytes). There are various options additionally, including SCSI RAID (e.g. Smart Array 5300 or even Smart Array 6400), GbE (DEGXA, original and/or modified), stock ELSA GLoria Synergy, various Radeon 7500 (also All-In-Wonder), NEC USB, audio cards and more. One of the two DS10s 'as-is', as it may have a faulty CD-ROM drive (it's also missing its 'badge/name plate' with "ALPHASERVER DS10" on it, below the "Compaq" logo, in case you should care). The skins are all intact, in good/excellent shape and included. I have various options to offer. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

FS: 2× HP rx2620 "Montecito"

by marcogb＠xs4all.nl

Two Hewlett-Packard Integrity rx2620 systems, with dual 9015 "Montecito" (IA-64 with hyperthreading, VT-x, etc.) dual-core processors, 24 Gbytes RAM, iLO/MP board and plenty of options (Ultra320 SCSI RAID, 10GbE, GbE-and-FC combo cards and much more). I should note, the processors have been installed last year, brand-new out of the box! (In fact, I can even deliver the original CPU boxes, with processor tools, included documents and so forth.) This type of CPU supports HPVM (also known as Integrity VM), which is a fairly recent feature. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

FS: 2× DEC PWS 500au

by marcogb＠xs4all.nl

Two Digital (Equipment Corp.) Personal WorkStation 500au systems, each with a stock 500 MHz EV56 CPU (socketed), 1? Gbytes memory, on-board DE500 Fast Ethernet NIC, on-board SCSI, on-board (MMOV- compatible) Ensoniq ES1888 audio, additional DE450 NIC, PowerStorm 3D30, an additional QLogic SCSI controller (same type as on-board). One of the two may have a weak battery, but it's fortunately a regular button cell type battery. I have various options to offer. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

CP/M clones & compatible OSes

Which makes me wonder > how common "almost CP/M" variants were... That's a really interesting question, actually, I would say. [Does a bit of Googling] There were, it seems, various Torch Z80 addons for the BBC Micro. The only one I saw or used was a Disk Pack: http://acorn.chriswhy.co.uk/docs/Torch/Torch_Z80DiscPack.pdf There was a time, when I was about 13 or 14, when I thought that this was about *the* most powerful and desirable computer setup I'd ever seen or heard of. ;?) What I had not appreciated until now was that Torch's version of CP/M was a special one, which ran from ROM. That is apparently why they called it CPN instead. There was also a standalone 2nd processor, no disk drives: http://acorn.chriswhy.co.uk/8bit_Upgrades/Torch_Z802ndproc.html There's a user manual for a CPN system here: http://acorn.chriswhy.co.uk/docs/Torch/Torch_ZDPUG.pdf It contains a little non-technical info: ? the TORCH CPN operating system, (a 16K ROM containing a CP/M compatible "look alike") ? ? INTRODUCTION The TORCH CPN operating system which is a CP/M "look alike" has much more flexibility than conventional CP/M. It has more "built in" commands and is easier to use. The most significant advantage of the TORCH CPN operating system, is that it is stored in ROM (Read Only Memory) rather than on disc. This means that on "power up" the TORCH disc pack and BBC micro are automatically ready to accept instructions typed in at the keyboard. ? Another CP/M compatible OS I was aware of was Pro-DOS for the MGT SAM Coup?: http://www.samcoupe-pro-dos.co.uk/whatisprodos.html ? What is Pro-DOS? Pro-DOS could be thought of as a Disk Operating System (DOS), However, it is more than this, it is a full Operating System that Provides compatibility with CP/M 2.2. In simple terms this means that a whole world of software that was designed to run under CP/M 2.2. will now run on the SAM Coup?. Pro-DOS uses the same Disk format as the Amstrad PCW 8256 and, as a result, it can read disks from this machine direct, this also Means that there is a vast range of software already available from sources such as Public Domain libraries. ? I hadn't realised it was by virus writer Chris "The Black Baron" Pile, who was imprisoned for writing Queeg, SMEG and Pathogen: http://en.wikipedia.org/wiki/Chris_Pile_(programmer) It is an admitted reverse-engineered effort as you can find from this interesting review, complete with an account of nostalgia-destroying 8-bit compatibility problems: http://www.samcoupe-pro-dos.co.uk/pdreview.html As for the Tatung, I've found very little info on XTal DOS, apart from something calling it " a compatible but beefed-up version of CP/M called Xtal DOS." http://www.tuicool.com/articles/myEBvq Anyone got more? Any more CP/M-compatible Z80 OSs? -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

Seeking information on some Qbus disk/tape controllers: Dilog DQ37, Emulex QT131 and UC07

by ethan.dicks＠gmail.com

Hi, All, I was going through a box of "interesting" cards last night and I came across three cards that I'm looking forward to using: o Dialog DQ37 - an S-box-handle Qbus SCSI controller o Emulex QT131 - a Qbus Pertec tape controller? o Emulex UC07 - a Qbus SCSI controller I found the UC07 manual on Bitsavers, so I'm good there for setup and configuration, but I was curious if anyone knows about different firmware revisions I should be aware of or seek to put on the card (I've owned plenty of Emulex communications controllers, and done plenty of firmware swaps on those, and since they put firmware (ROM chip) upgrade instructions in the manual, it makes me practically expect to have to do something to it). I could not find more than a couple of comments about the QT131, but I'm reasonably certain whatever jumper settings are on there are a) the defaults, and b) just fine. If anyone here has any experience with the QT131 or even better, a manual, that would be appreciated. As for the Dilog DQ37, I can find nothing except 3rd-party resellers offering to sell me one if I click the "give me a quote" button. The ones I have (2) appear to have the single-ended SCSI portion of the board populated and have a large bare patch that, from the component values on the silkscreen, seems to me to be for High Voltage Differential. No biggie. I don't have any HVD drives anyway. I don't own any S-box hardware, so "just plug it in an see what it looks like" is not the preferred method - I'd like to know more before I go further. I'm especially wondering if this is a TMSCP-only controller or if it will do MSCP and/or TMSCP, and if there are any firmware variations I should know about. So... anyone here know about these cards or where to find docs (besides the UC07 docs on Bitsavers)? Thanks, -ethan

Microvax II won't boot, hardware error?

by saquinn624＠aol.com

Make sure all your connections are firm and good, especially the PMI connection over the ribbon cable. I'd probably even take the ribbon cable off and re-crimp it in a vise to make sure the connections are firm.

I spec'd Tygon (brnad name) as that was available to me. Most any generic Vinyl tubing works so long as it fits tight and has enough wall thickness. After about 10 years it tends to get hard, the fix is obvious. Allison
