Heathkit H-11A (LSI-11) on eBay

by classiccmp＠crash.com

Be interesting to see what happens with this: Heathkit H-11A (DEC LSI-11) with no peripherals but lots of manuals and some software on paper tape and 8" floppy. Hey, the Buy It Now price is a very reasonable US$6,900! ;^) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2302242389&category=4193 Do I need to point out that if I had it, I wouldn't sell it? No connection to the seller, et cetera... --Steve.

What's better than canned air?

I was wondering about excess pressure the other day. I thought about a pressure switch to shut off the motor, but they seem to be quite expensive. Or am I just looking in the wrong places? Does anyone know where I could get a pressure switch suitable for about 120 psi, cheaply? > The only things I don't like are it doesn't last very long.

Take it apart and wind 4"-6" of PTFE tape round it the male fitting. You can get the tape from any place that sells air accessories or vacuum pumps, or most plumbers suppliers. -- Pete Peter Turnbull Network Manager University of York

Bulk erasing disk packs

by GOOI＠oce.nl

!! RED ALERT !! If you do not have the drive hardware (and computer), you *cannot* erase the disk packs without rendering them worthless! Bulk erase will destroy the data *AND* the servo tracks! If you do bulk erase the disk packs, you can safely throw them away because most of us (all?) do not have the equipment to rewrite the servo track information. BTW. I would like an other RM03 disk pack. I have got only a few of those. I hope to spin up my RM03 in a few months; spare fuses are standing by ... - Henk. > -----Original Message----- > From: Tim Myers [mailto:tim.myers@sunplan.com] > Sent: donderdag 23 januari 2003 12:17 > To: cctalk(a)classiccmp.org > Subject: Bulk erasing disk packs > > > I've managed to get a haul of DEC disk packs, the condition on getting > them out is that I erase them (no drive hardware available > unfortunately).

BBC Micro - assemblers - info needed

by philpem＠dsl.pipex.com

Hi all, I've just downloaded three assemblers from the ROM archive at http://bbc.nvg.org . Catch is, none of them include manuals. I've got copies of: VASM65 v2.0E by Vida Rebus ASM 1.10 by SYSTEM (claims to be the "ASM 6502 Macro assembler V1.10", "Copyright (C) 1984 SYSTEM"). Contains text strings like "Press play", so may be a tape->ROM conversion. ROMAS 3.02 by TBK Associates (full copyright string = "ROMAS 3.02 (C)1985 TBK Associates - S.C." Has anyone here got any documentation for these assemblers? I'd like to get at least one of them to assemble *something*. Perhaps a "Hello World" program? Also, Vasm outputs Intel Hex files from what I can gather - does anyone here have an Intel Hex -> Binary converter for the BBC Micro? Finally, does anyone know how some discs were formatted so they were compatible with 40-track and 80-track disc drives? Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

VAX VMS Question

by crl＠rti.org

Does anyone have a VAX running VMS connected via ethernet to a Cisco 2950 series switch? I have had the VAX connected to a 2900XL series switch for a year with no problem, but in doing upgrades, moving it to the 2950 has caused major character delays, and other problems between the VAX and clients connecting to it. Everything else connected to the switch is working fine. Thanks Carl Lindahl ITS NOC ============== RTI International Ragland Building P.O.

OT (plug) reply: RE: A plea to classiccmpers

by Edward.Tillman＠valero.com

If you want the flexibility of a "hotmail" ((I do, and I have it), but don't want all the animated ads, get a bundle pack like Norton Internet Security. I don't work for 'em, and I've only recently started using the package, but it has a WONDERFUL ad-ware blocker that leaves your viewed web page intact, while simply screening the ad location (turning it black or transparent). I paid $29.95 for my copy, including a 1-year subscription to NAV's virus updates, on the website: NextAisle. Also, there's a couple of freebie packages available on C|Net's Download.com: "Adware," whick you can use to clean your system and registry of cached ad files, and "Pop-up Stopper," which does exactly what it says it does. Both occationally leave you with WIndows Message Service error messages (Of course! Your Adware thinks its broken if it can't cover your screen with its ad!), but these are background, and much easier to dump than the ads themselves. Cheers!

A way to erase OTP components?

by Arno_1983＠gmx.de

Hello everybody, this is something I've been wondering about for some time now. Perhaps here is the place to ask, since it's about one of the "inner secrets of silicon": Tony Duell wrote: > The 8751 is the EPROM version of the 8051 microcontroller. It's otherwise > identical to it. > > If it's in a ceramic package with a quartz window, then you can erase it > like any other EPROM and reprogram it. If it's in the plastic package, > then it's the OTP version. If in fact the same die was used in both components, then it's only the plastic (which is impenetrable to the commonly-used ultra-violet light) that prevents the OTP variant from being erased and reprogrammed. However, there are kinds of radiation similar to light which *will* penetrate the plastic housing...you see where this goes? Will the memory be erased when you, say, X-ray the OTP component, will it stay unaffected, or is the thing just going to die?
