Free: Cabletron ST-500 thickwire:aui ethernet transceivers

by mvgslc＠earthlink.net

I think I already know the answer, but perhaps someone can make use of these in a really authentic LAN at home :) - free (you pay shipping from St. Louis, MO): small box of Cabletron ST-500 thickwire to aui ethernet transceivers, working when removed from service. There are currently 4 or 5 units in the box (more may show up shortly). I'll hold on to these till 15 October, then they will be recycled. Please email offlist soonest if of interest. Thanks!

Rebuilding the PDP 11/34 (2volts?)

The M7891 is a memory board...I believe that connector is for factory testing but I'm not sure about that. The M8265 is one of the pdp11/34a CPU boards. The connectors on them are for the cache and FPU options. -Dave -- Dave McGuire Laurel, MD

UNIVAC Core

by cswiger＠widomaker.com

Hi Gang - long time no type. I'm just looking for any insight or experience with a Sperry + Univac core memory card 90536-7128081-00 D Looks to be a later generation core module, lots of 14 pin dips with numbers like 7427, 7438, MC7524, 7502, 7503. card itself is 10.5" tall, 15" wide with 3 connectors along the bottom, each connector has 2 rows of 28 contacts (48 * 3 contacts in all) on .1" centers. This instance is in clean condition - I'd love to build an interface to it just for a crazy fun project. Chuck cswiger(a)widomaker.com

Twoflower says

by optimus＠canit.se

I found this brill note by Twoflower (a Triad member, I think) in a interview at http://www.c64.sk/ : CreamD: How do you feel about the party, what is your overall opinion? Twoflower: Overall it was a great party. Save for some small backlashes, like missing friends which said they would show up, it was hilariously funny to be there meeting everyone. Actually, it's kind of easy to forget how much such an event means for the social bonds of the scene, but when you're there, it really gets a good hold on you. Scene parties, no matter how small, are important for the scene, its structure, its competition and its friendship and should always be pushed for - but it's also important to remember what these meetings are about - and what they're not about. CreamD: I don't understand. What do you mean by that what they are and aren't about? Twoflower: Meetings are about the scene, the living, creative scene of which we consist. It's not about retro feelings, of nostalgia or something like that, but about creating the bonds and feelings for the scene I described above and pushing the efforts on what you can do with 8-bit computers further - not back to the 80'ies. The scene, and the parties, must first and foremost be focused on the scene, for the scene and by the scene - enough said! :-) I think that sums up my views on emulation and the "retro" trend in a very neat package. Retro is about what has been, not about what is. -- En ligne avec Thor 2.6a. VIRGO (Aug 23 - Sept 22) You are the logical type and hate disorder. This nitpicking is sickening to your friends.

don't forget the 286 pile event. a team gets 1 minute to throw 286's at least 10 feet and create the tallest pile. they took all the fun out of the mac toss. with those built in handles on the imac, its just too easy to score a "swish" into the dumpster at 50 paces.

HP 9826/9836 computer battery pack

by rigdonj＠intellistar.net

A while back someone was asking about what the battery in the HP 9826/9836 was for. I replied that it was used for a RT clock and that if could also be used for shutting down the computer gracefully in the event of an AC power loss. Well, I finally found my manual for it. It's option # 050 and PN 98270 (cost $1515 in 1983). Now that I have the manual in hand I can give you exact answers to any questions about it. (FWIW I just picked up an 9826 that has this option in it this past weekend.) Joe

Paging Will Jennings

by cfandt＠netsync.net

Will, I've tried a couple of times to contact you by email regarding whether you intend on obtaining the remaining DEC gear I still have. Didn't bounce back but I figure maybe Hotmail doesn't notify senders of non-delivery. Anyway, could you get back to me ASAP with your intentions on this stuff? I must move on this soon as I need the space very much. Apologies to the list for using the bandwidth. -Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.antiquewireless.org/

IBM ROM BASIC or lack thereof

by Robert_Feldman＠jdedwards.com

Yes, providing a default ROM monitor program would be useful and simple to implement. The Otrona Attache would go into terminal mode if it couldn't boot the OS. It also provided a set of diagnostic routines that could be run from terminal mode. I agree with you that error messages should be more informative. One problem is that they often just tell you the last of a series of errors. "No ROM Basic" accurately describes the last "error," but it might be more useful to the user to also know that the system got to that point because it couldn't boot from disk. - Bob -----Original Message----- From: ard(a)p850ug1.demon.co.uk [mailto:ard@p850ug1.demon.co.uk] Sent: Wednesday, October 03, 2001 5:43 PM To: classiccmp(a)classiccmp.org Subject: Re: IBM ROM BASIC or lack thereof <snip> I wish more manufacturers would put a program in the boot ROM that allows reading and writing to memory, running (machine code) programs and preferably also reading/writing I/O ports (if they're not memory mapped). It makes debugging the machine a lot easier if it can't boot a disk (or if you don't have a bootable disk for the machine, at least you can do something with it. Tiny (or otherwise) BASIC allows one to do this. So does Forth. Or just a little machine code monitor. With ROM space being so cheap these days you'd have thought they could find room for something like this... -tony

6502 BASIC or Assembler and Intel 8271/WDC 1770 info req'd

by ajp166＠bellatlantic.net

The 8271 is a poor choice as it does not do MFM (double density). Either use 8272 or the 1770 you have. The 1770 does not overclock reliably.

Restoring classic kits we built way-back-when

Ethan Dicks wrote: >one aspect of classic kit building I have a question for the group >about is, what about stuff that we built ourselves 10+ years ago that >still works, but might need some touch-up. If the solder joint in question meets the following criteria: a) bad enough that fail-open is a credible risk b) in a pathway such that fail-open could cause damage to other components (particularly hard-to-replace ones) I'd say it should be retouched. In any other case, I'd say that the risk of damage, plus the loss of historical value, are convincing arguments to leave it alone. Bottom line, though, is that they are your kits, and whatever you want to do with them is Ok. Good question, though. - Mark

OT: Archaeological restorations (was RE: Restoring classic kits w e built way-back-when)

by Robert_Feldman＠jdedwards.com

On topic: Leave your old hardware the way it is, for historical reference. Off topic: Coins are so boring ;) (though they last and are dated; I admit I have used them myself, though). When I backfilled my excavations of a 3000 BC temple mound on the Peruvian coast, I put a basket-full of old shoes in first (the site was being used as the modern town's garbage dump). In another case, I dumped a load of washed and sorted shells in a pit at a village site, and put in a dated newspaper page. A few years later, another group re-excavated at the village, found the shells, but thought the newspaper was intrusive (there is a lot of site looting in Peru) until they happened to mention to me the "cache" of shells they found, whereupon I told them what had happened. -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: Thursday, October 04, 2001 10:17 PM To: classiccmp(a)classiccmp.org Subject: Restoring classic kits we built way-back-when <snip> Specifically, I have several things <snip> that I made when I was a teenager. <snip> I'm debating re-soldering these items <snip> I took history and archaeology in school; <snip> When my advisor restored the bed of a large monochrome mosaic near Isthmia, he threw several modern coins into the concrete bed so that future excavators would know that it wasn't ancient concrete. <snip> -ethan

HP 9000/847S

by steven_j_robertson＠hotmail.com

I have HP/847S and found it to be a very effective space heater. Since I wasn't particularily impressed with it's performance, I have opted to run a smaller and more energy friendly HP/832. I use my HPUX box(s) primarily as a database server (running APACHE, PERL, and INFORMIX), application develpment using a Z80 cross assembler, and a backup system for all my other "stuff". I have more trust in 9-track tapes than other backup media. As part of their Y2K support program, HP offered HPUX-10.2 as a free upgrade. The upgrade package included everything you would need to get your box up and running. As far as I know, the upgrade program has been discontinued. You can find release notes and installation instructions at: http://docs.hp.com As I recall, the basic install will give you licenses for two concurrent users. Additional licenses can be activated by installing the license upgrade. This requires a key to activate. The keys were provided by HP with the upgrade based on the number of licenses the user had previously bought. As with the software, those "Free" license upgrades are probably no longer available. Some of the CDs included applications but, you need keys to install them. An alternative is to download and install apps from the HPUX freeware site (http://hpux.cs.utah.edu ). Send me your address off list and I'll get a copy of the OS to you. NOTE: You'll need a bootable CD player to install the software. ALSO --- If any your disks already have an OS installed, there is a simple way to circumvent the ROOT password.
