He didn't have a clue. It's tough for a techie to go into court and come out looking smart. You can be the world's best expert on some important area of technology and come out completely skewered every which way >from Sunday if you try to look like a smarty-pants. Just being the expert who was in the thick of things puts you at a real disadvantage in almost every legal situation, no matter how humble you try to be. And even if your side wins it doesn't mean you're gonna be a happy guy. Look what happened to Armstrong. All these legal tribulations from the early 1900's seem just as relevant (as business and/or moral lessons) today in the 21st century. Tim.

PC Keyboard to serial adapter...

by lbickley＠bickleywest.com

One item I've needed on several occasions was an ASCII keyboard (TTL or RS-323 levels) for a vintage system. While I do have a few Keytronic serial keyboards with TTL output - they are old and can be "flaky". I found a pair of products that convert a standard PS/2 keyboard to RS-232 ASCII output (and can be modified for TTL). In addition, the vendor was very cooperative about modifying his product to meet the needs of those of us in the vintage computer community. To be specific, the standard products support baud rates from 2400bps to 115Kbs. I contacted the owner of the company ("John Ursoleo" <jursoleo at att.net>) saying that for the vintage systems I was working with, I needed lower baud rates. John asked me to send my units back - and reprogrammed them to support the following baud rates: 110, 300, 600, 1200, 2400, 4800, 9600 and 19,200. He sent them back to me, and I tested them again with the low speed option and they worked great. The "low baud rate" version of these products can be ordered with the /LB option. Here's where to get the products, manuals, etc.: PS2ADPT http://www.versalent.biz/seradpt.htm PS2PRO http://www.versalent.biz/ps2pro.htm Note: The standard output of this product is RS-232 voltage levels - but it is easy to modify them for TTL levels. Doing so voids the warranty - so you are on your own with this mod. I have NO financial interest in this recommendation - it's just a good product I've found useful...

Serial Port Web Server

by technobug＠comcast.net

A friend desires to leave the hot desert this summer and move to the cool mountain and yet maintain contact with his PDP11 with which he still runs his business. He has a rotten phone connection, but good internet. He runs a highly modified version of RTST 5x and cannot reasonably move his stable 30 y/o applications to later/other OS's. I would appreciate knowing what the listers use to accomplish same. -> CRC

Reproducing Printed Circuit Board Artwork

by tshoppa＠wmata.com

http://www.mhtest.com/ has done it before, maybe you won't even have to send them your boards :) For many purposes I think I'd be happy with a good 600 DPI color scan of both sides (including silkscreen). I don't think that modern PCB processes will by default produce a board that "looks like" an Altair era board (I remember the silkscreen actually covering tinned solder pads.)

From personal experience I'm inclined to believe the practice of 36 hour shifts is no more or less than institutionalized hazing, as has already been addressed by other posters. Any complaints were always met with derision of the "you think YOU have it tough, when *I* was an intern I had to walk uphill both ways barefoot in the snow 36 hours a day", etc. Especially among surgeons, who usually won the macho-asshole award hands down. -Charles

Serial Port Web Server

Honestly I'd recommend a PC with OpenBSD over a Serial > Port ethernet server. --- snip --- A VPN router and a 4 or 8-port terminal server should be adequate. Xyplex terminal servers, while a PITA to configure, seem pretty darned stable. An MX1600-04 is a 1U rack size, and can support 16 concurrent sessions. It's best to use them with a multiplexor that supports modem control though, so that if your Telnet session drops, your interactive session becomes detached. Otherwise, the next person connecting will pick up your session. I've successfully interfaced Xyplex series routers with Emulex CS02's, and DHV11's. It's been some time since I've messed with them, though, so I can't readily spout the exact terminal server settings & cable pin-outs, so I'd have to dig them out of my storage unit for examination. Lantronix terminal servers will also work; they're alot smaller, but not my favorite. (I couldn't get rid of the pesky "Welcome to the Lantronix Terminal Server" message.) T
