by classiccomp-tech＠bouncy-castle.demon.co.uk

Which models of the MicroVAX3100 were limited to <1GB boot disks? I've a stack of MicroVAX3100 model 30s that I'm tarting up & I'm trying to acquire HDDs for and couldn't find if they were affected by the limitation? ta greg (ps : anyone UK want a 3100? Just ask. shed is full of the things rescued from Witchy / Jules Richardson :)

Congratulations to Ethan Dicks!

by kahrs＠caip.rutgers.edu

Ethan won the "out-of-the-way-corners-of-the-earth contest" on Velonews (competitive cycling magazine following the Tour de France). and, if they decide to start an "insane readers" contest, they assure him he's in the running as well. Congratulations!

Panasonic RL H-1400 - Information Needee

by spectre＠floodgap.com

> About the best I could do is to snail-mail the ROM to > you. -or- I'll be in San Diego tomorrow - Monday. That's a very generous offer, but there are two problems ... first I'm presently in San Bernardino :( and won't be back in San Diego until Sunday, and only Sunday at that. The bigger problem, though, is actually getting the capsule out to read it. I opened up my HHC-4 and dug out the NYL capsules, which I hadn't examined too closely before. They *seem* to be regular 24-pin EPROMs (with an NYL sticker conveniently covering the UV window; they're 4K TMS 2532s, for those interested). The problem is not the chip, which seems to be a regular old ROM. The problem is that the DIP legs are wrapped *around* the capsule carrier, and digging the DIP out is probably going to damage the chip. I could try wiring it into my Jason-Ranheim Promenade, but I don't see much I could attach the wires to on the capsule side, and soldering leads directly on to the DIP legs is right out because I'm very worried I would ruin this first example of this capsule I've ever seen! Is the BASIC ROM similarly "wrapped" on yours? If it is, perhaps there's another way of doing this -- some way of reading out the contents of the ROM using the HHC itself. If you've got the printer, maybe if we could scrabble some way of printing out a hex dump, assuming this BASIC is halfway sane and has PEEK and POKE or a moral equivalent. We'd just have to figure out where in memory, but this is easier than it looks because it would have to start on a 4K page boundary, meaning we'd only have to glance at 16 possible areas. If one of them has BASIC keywords, we've found it. All this to say I would be *very* antsy about damaging a *very* rare ROM with my relatively novice EE skills, despite the fact I want it *very* much! -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

DECMate II

by rich_bramante＠yahoo.com

I just rescued one of these. No docs/sw. It has 2 RX50 drives, but no hard disk. It powers up to a DECMate II screen with a flashing cursor in the ULH corner. Anything interesting I can do with this to play around without a hard drive? Any floppy images I can snag (will it boot from floppy?) Thanks. __________________________________ Do you Yahoo!?

Rust on tape heads

by root＠parse.com

I've noticed a few spots of rust on some TU55 tape heads that I have. I'm wondering what I should do about it in the short term -- I've had an idea of putting something on the heads and then cleaning it off later, like oil or vaseline or... ? Any suggestions? Is there anything I can do with the heads later to clean the rust off? Are they totally hosed, or will they still work? This is on my "todo list" as far as restoration goes, just haven't gotten to it yet, but wanted to prevent any further damage if possible...

Cleaning up yellowed/grubby plastic?

by philpem＠dsl.pipex.com

Hi, Does anyone happen to know of a trick to remove (or lessen the effect of) the yellowing that tends to happen to lighter-coloured plastics? I've got a few monitors here that are pretty bad - the yellowing I can put up with, but the difference between the non-yellowed areas and the yellowed areas shows up like a sore thumb. Is this just one of those things that happens to plastics that's best ignored?

S.F. Bay Area -- PDP-11 HW available -- Disks and Tape for 11/44

by wmaddox＠pacbell.net

I was up at Mike Quinn's on Saturday, and inquired about classic computers. After mentioning the PDP-11 by name, the guy there (Maurice) pointed me to an 11/44 he had in the back. The racks were already spoken for, and the contents had been pulled out and were sitting face-down on the floor. There was an 11/44 CPU, two RA-81 disk drives, and a 9-track tape drive, a TU-80 or TU-81, I believe. He was willing to let it go pretty cheap, $100 for the CPU and RA-81s, or $50 for the CPU. He thought the motors in the tape drive would sell for $25 each, so he wanted at least $50 for that. Seeing the lack of respect this poor old machine was getting (dumped on the floor to salvage the rack), and having some space in my trunk, I snapped up the CPU without much further thought. I figure a collector should have a shot at those drives before Quinn's sells them to a scrapper or someone who wants to strip them for parts. I don't have the space for them, nor enough interest in the later 11's to justify renting any more on their account. I could possibly be talked out of the CPU. I'd certainly take a smaller Q-bus '11 in trade. Heck, a convincing promise of a good home with some happy peripherals to talk to and reimbursement of the $50 I spent would probably do. :) --Bill
