help (re) booting xenix after cmos battery failure

by brad＠heeltoe.com

A friend of a friend has an old xenix machine; Compaq DeskPro 386 running Xenix. He shut if off after running for years and it won't boot because the cmos battery is dead. The disk is an ESDI drive attached to a Compaq ESDI/FLPY controller (copyright 1989) ISA bus card. He says can't see any way to enter a "setup" mode in the BIOS. Anyone know how to fix this? apparently it has his Alfa Romeo motor club data on it (so it's clearly +10yo :-) Anyone know if the xenix fs can be mounted on linux? (I doubt it, but I thought I'd ask) -brad

Standing Request: Need Xerox 820 II

by snhirsch＠gmail.com

I have been on a quest to obtain one of these. If you have one for sale at non-bandit rates (see classcomputermuseum's auction for an example of the latter), or know of one, please advise! Thanks. (Have a real 820 motherboard and a Ferguson BigBoard already. I need the actual machine) STeve --

HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

by hpjimbondoris123＠dorisland.net

Phil: If you download the manual you will see that it is in color and was scanned at 300 dpi color. I believe that HP did this on purpose so that you could not copy it on a copy machine but rather contact them and purchase another copy. On the rom listing I had to even play with the contrast and brightness just to get it to be read. Please if you want take a crack in reducing the file. As I spent the entire day just on the 40 pages it was the best I could do to get out the document for those folks whom have the trainer without the manual when it came to the schematics those were scanned in black and white as they are black and white.

TU-58s (was Re: Some progress with my PDP-11/73 system)

I survived a PDP-8 with a TD8E and TU56, but it was >somewhat tedious (cool to watch, though). TU-58s weren't as cool, >IMHO. So happens one of my "small" pdp-11s uses a Tu58. the system is a BA-11V with an 11/23 256k of ram, DLV11J and MRV11 rom(boot). Takes 10 minutes to boot, setup VM: then copy key files to and reboot. After that it's pretty decent even if I have to access a file on tape. Everytime I runs it with a bunch of kids of the current PC generations they go gaga and comment on how slow then I explain the amount of ram and storage then they are amazed it can be a functional machine with so little. They can't imagine a useful machine with 32kW of ram and 256kb of storage. On the flip side I've used that same Tu58 to bring up iron that had no removable storage. It's slow but very dependable.

more Flexowriter

by sturges＠vt.edu

Dear Classics: I just gotta get a Flexowriter. Who has one that will sell it to me? I had one years ago and gave it up in time of crisis. (Yes, I deserve it.) No reasonable asking price refused! Cheers, Dr. Bob

Looking for Norsk Data ND-100 info.

by axelsson＠acc.umu.se

Hi! I'm looking for ND-100 information. A couple of my friends have started to work on a ND-100 emulator and it is progressing fast... fast to a point where we are lacking information about the inner workings of the ND-100 CPU. Specifically we are looking for information on the real time clock interrupt and micro code programming but other information (manuals, schematics or programs) is also interesting. I currently have the following manuals that I'm transforming into pdf:s as time permits. * ND-06.007 BIG MULTIPORT MEMORY SYSTEM * ND-06.014 ND-100 REFERENCE MANUAL * ND-06.016 ND-100 INPUT/OUTPUT SYSTEM * ND-30.003.06A : SINTRAN III System Supervisor * ND-30.025.02 : COSMOS Operator Guide * ND-30.071.1 EN : ND-5000 Series User Guide * ND-40.004.06 : Norsk Data Documentation Catalogue * ND-40.012.1 EN : Information Pamphlet for Norsk Data Customers * ND-60.014.01 : Page III-1-1 to A-9 (some pages missing) * ND-60.046 TRACE ROUTINE * ND-60.047.03A : NORD PL User's Guide * ND-60.050.06 : SINTRAN III Users Guide * ND-60.066.04 : ND Relocating Loader * ND-60.074.01 : NORD-10 FORTRAN SYSTEM Reference Manual * ND-60.088.03 : ND Screen Handling System * ND-60.096.01 : Page 2-16 to D-3 * ND-60.111.03 : ND TPS User's Guide * ND-60.132.03 : SINTRAN III Timesharing/Batch Guide * ND-60.151.02A : SINTRAN III Utilities Manual * ND-60.158.3 EN : SYMBOLIC DEBUGGER User Guide (2 ex) * ND-60.163.4 EN : COSMOS User Guide * ND-60.196.01 : BRF-LINKER User Manual * ND-60.230.01 : SINTRAN III J-version Release Informaton * ND-60.236.1 EN : ND-100/500 SORT-MERGE User Guide * ND-60.264.1 EN : SINTRAN III User Guide * ND-63.001.02 : Introduction to NOTIS-WP * ND-63.026.02 : NOTIS-CALC Handbok (in Swedish) * ND-63.042.1 EN : NOTIS-WP M Release Information for new users * ND Ring binder with cable diagrams * Am201B/Am2901C Four-Bit Bipolar Microprocessor Slice, AMD. Page 5-1 to 5-18 * PASCAL : Instructions in Swedish for running Pascal on ND-100 If you have anything outside of this list please let me know. I will borrow for scanning, buy or trade anything of interest. The hardware we got access to is a ND-100 satellite, two ND-100 racks with disks and 8 inch floppys in parts and a nonfunctional NORD-10 in a rack. When time permits we will try to get it running. /G?ran

Two more Craters & Freighters happy experiences

by legalize＠xmission.com

I recently had two more items packed and delivered to me by Craters & Freighters. Holy shit, what a difference it makes with that company. A Tektronix 4170 local graphics processor and an Evans & Sutherland PS 390 base unit arrived with no scratches, no falling apart pallets and everything intact. The tally so far: + seller freight packed deskside SGI Onyx + C&F packed lot from dovebid (Tektronix graphics terminals) + C&F packed Megatek graphics terminal + C&F packed E&S PS390 + C&F packed Tektronix 4170 - CTS packed deskside SGI Onyx & Octanes - adcom worldwide packed SGI Octanes, O2s and monitors In the case of CTS/adcom worldwide, the only reason that I used them and not C&F is that there wasn't a C&F that could go to Reading, PA and pick up the stuff from a dovebid auction. C&F may not be the cheapest; to be honest, when C&F service is available I don't even bother to check with other freight shipping service companies. However, what good does it do you to save a few dollars on shipping and have something arrive smashed or cosmetically ruined because of poor packing? I heartily recommend Craters & Freighters for your packing and freight shipping needs. <http://www.cratersandfreighters.com> -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

SS10s and SS20s free for local pickup or $10 + actual ship

by rescue＠hawkmountain.net

I have 3 SS20s and 4 SS10s. Mostly complete. All have one or more processors (ranging from SM41 to SM61), I believe all have RAM, and some have one or more drives. No GFX as these were last used for servers. These are free for pickup in Sharon, MA 02067, or I can bring them with me to work in Cambridge, MA 02140 (on the same road as Alewife T station). If you want one shipped... $10 + actual ship with the $10 to cover the materials/time to pack and haul to PO/FedEx/UPS/etc. If these don't move before that dumpster leaves here (1-2 weeks >from Friday), then I'll pull the CPUs, RAM, and drives, and heave them into the dumpster. The SS20s are all Aurora I chasis. I don't recall any having CD rom drives... one or two fo the might have floppy drives. -- Curt
