Hot Wire to Cut PVA Bond Between a CRT and Its Safety Lens?

by bobvines00＠gmail.com

Does anyone have instructions or a schematic (or a pointer to a URL) on how to make a "hot wire" device to cut the PVA bond between a CRT and its safety lens? What kind of power supply (how much power), "hot wire," etc.? I'd like to build one of these "hot wire" devices, *safely*. Thanks, Bob

Looking for Stanford Ethernet AppleTalk Gateway (SEAGATE) source code

by engel＠multicores.org

Hi, according to http://www.megalextoria.com/usenet-archive/news021f2/b37/fa/info-mac/000016… Bill Croft at Stanford developed an Ethernet to Apple LocalTalk gateway that ran on the original SUN 68000 CPU board. Unfortunately, I cannot find the files mentioned in that post on any info-mac mirror (or somewhere else on the net): "The beta release of our Stanford Ethernet - AppleTalk Gateway (SEAGATE) is ready. On [SUMEX]<info-mac> the files are: seagate.ms documentation in -ms format seagate.hard the wirelist for the applebus interface seagate.shar1 the main gateway sources (including the above doc's) seagate.shar2 the ddt, dlq, testscc, and tftp subdirectories" If you happen to have these lying around in a dusty corner, I would be happy to obtain a copy. According to Wikipedia, this code also was the basis for the commercial Kinetics FastPath gateway product: http://en.wikipedia.org/wiki/FastPath Best wishes, Michael

Wanted: Sharp LM64C032 LCD panel

by tothwolf＠concentric.net

I'm looking for a Sharp LM64C032 LCD (640x480, 16 color) as a replacement for a Compaq Contura 3/25C (25MHz 386). I saw a few far-east sellers on eBay with used displays, but they want over $100 for them which doesn't seem too economical for a machine with a value of around $50 or so. Does anyone happen to have one of these LCDs sitting around in their junk pile? I recently pulled the machine from storage and was thinking of using it to run my old parallel port interface EPROM programmer, but I can't do much with it with a broken display. The sad part is I actually installed this particular LCD for the original owner back in the early '90s, but apparently it got broken sometime before he gave me the machine. (The original panel failed electronically, and it is too bad I didn't keep it back then since I could have scavenged it for parts now.)

1964 Honeywell EDP Sales Presentation - H-200 / H-300 / H-800 Info

by billdeg＠buzz1.com

May 1st, 1964 the Honeywell Electronic Data Processing Division Bala-Cynwyd office sales team led by Stephen S. Berry (Sales Representative) and H.L. Sweatt (Branch Sales Mgr) submitted their proposal to DuPont Company to upgrade the Treasurer's Department computer system. DuPont had been running an IBM 1401 system but they were looking to upgrade. Initial discussions between the two companies appear to have been about the H-200 computer. After assessing the needs of the Treasurer's Department, Honeywell is shown to suggest that DuPont instead acquire a system comprising of combination of H-800/1800, H-300, and components. For reference Honeywell also included info about the H-200. This proposal contains pricing and system configuration. It also contains a comparison between the IBM 1401 and the Honeywell B-200. A nice set of one-page product sheets about the H-200 line are included. This is an excellent historic reference because it puts the systems in context, from the Honeywell perspective. PDF Set: http://vintagecomputer.net/browse_thread.cfm?id=589 Not sure where on BitSavers.org one would put this set as it covers multiple systems as well as a compare contrast with IBM 1401. -Bill

Problem Installing Ultrix on DECstation 2100

by robert.jarratt＠ntlworld.com

(apologies to those on the DecTec list, looking to widen the audience) I am struggling to surmount a problem installing Ultrix 4.5 from a CD-ROM onto a DECstation 2100 (MIPS) After choosing the type of installation (basic or advanced) it tries to offer the system disk selection. However, it keeps failing because it is detecting the CD-ROM drive and saying it has an invalid block size. I can hear it spin up the hard disk that I want to install on, so it should be finding a suitable hard disk, but it looks like it keeps choking on the CD-ROM drive. I can't tell if it is failing to see the hard disk properly, but when I tried NetBSD on the same disk, and in the same machine, it is fine, so the hard disk shouldn't be the problem. Any ideas on how to resolve this? Thanks Rob

Favourite text based word processing software

Ian King <isking at uw.edu> suggested: <...> > For low resource AND cognitive overhead, how about using either LaTeX or > HTML tagging, which could then be interpreted in a simple mapping table > for > a given printer?

A combination of this (for in-line emphasis or font changes) and perhaps some beginning-of-line dot-commands (like runoff, and also in WordStar) would likely be adequately expressive (I've done entire reference manuals using only MarkDown), easy to implement, and easy to parse for formatted output (printed, HTML, or whatever). ~~ Mark Moulding

Nice LSI-11 brochure

by jnc＠mercury.lcs.mit.edu

There's a nice LSI-11 brochure going on eBay: http://www.ebay.com/itm/291318103446 It's got pictures of a lot of different kinds of cards (useful for ID purposes), a modest amount of technical content, etc. Definitely worth having if you're a PDP-11 collector, and can get it for not too much (I already have one, don't need another... :-) Noel
