Converting ASCII to Hex (was: 1st stage loader for IMSAI - need ascii to binary conversion)

by tsw-cc＠johana.com

Really this is pretty easy (this does NO error checking, and only accepts upper case characters): int hex (char ascii) { int value; value = ascii - '0'; if (value > 9) value += '0' - 'A' + 0x0A; return value; } Improvements are left as an exercise for the reader/student. -- Sorry, No signature at the moment. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Metaphor Computer Systems

by john＠johnweeks.com

Curt, I happened to stumble over a posting that you made on the web about a year ago talking about installing some "Metaphor" computers. I am a former Metaphor engineer. I have a slide show on my web site that they developed to celebrate the death of the company. The software is still around, now called "Meta5". I don't want to invest too much in a note that I don't know will ever be delivered, but if it does make it to you, let me know, and I can fill you in. -john- ============================================================ John A.

eBay Monkey Business

by mardy＠voysys.com

I could be wrong, but there's something fishy going on over at eBay. First an IMSAI and an Altair 680 being bid up to astronomical prices and now a less than stellar SOL-20 goes for $7100.00 to someone who's last couple of purchases were cell phones. This all this activity is in fact some type of a scam, it is going to seriously hurt legitimate buyers and sellers. -Mardy

To Whom It May Concern I'd like to know the E-Mail-Adress from Bob Maxwell. He wrote an article in your forum about HP64000-floppys in the year 2004. I need more Information about these floppys.

Border US to CA (Was:Ebay: pdp 11/34 + lots of stuff)

by devonstopps＠gmail.com

I remember the discussion about bringing classic computers across the border from Canada to the USA, but, has anyone got any experiences going the other way? Any issues since many of these systems are USA country of origin? Especially with big iron, where you'd have a trailer or big truck...

Two days left, I figure somebody with a big truck wants to save it. I normally wouldn't post about an ebay auction, but this one doesn't mention pdp-11 in the auction title and seems to have been overlooked. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=120223434668 jdavis

EBAY Alternatives, was Re: eBay Monkey Business

by marvin＠west.net

I stopped selling on ebay before the January 29th announcment and am totally disgusted with what passes for management. (major rant deleted) Search youtube for ebay boycott or ebay strike and there are a number of "editorials" there as well. I suggested to Sellam that NOW would be a good time to get the Vintage Computer Marketplace back online, but it hasn't happened yet. Since I haven't kept track, are there other classic computer related places to buy and sell? A "yes" answer should be followed by the sites URL :). > In case you all had not noticed, there was a major change at Ebay this > week.

HP2100 MSU BASIC

by Tim＠Rikers.org

I've gotten back to trying to get MSU BASIC running. My current edited sources are here: http://rikers.org/hp2100/22255.asm http://rikers.org/hp2100/22255mon.asm Here's a transcript: sim> g 30000 CLOCK I/O ADDRESS? 10 LOG TTY I/O ADDRESS? 12 NUMBER OF CHANNELS? 1 CHANNEL 1 TTY I/O ADDRESS? 11 CARD READER IN SYSTEM? YES OR NO: NO PHOTO READER IN SYSTEM? YES OR NO: YES PHOTOREADER I/O ADDRESS? 14 ENTER CODE-WORD TABLE ACCOUNT NUMBER? 0 CODE WORD? ROOT ACCOUNT NUMBER? /E ENTER INFORMATION TABLE 0 /E DECIMAL FREE CORE AVAILABLE: 8828 STANDARD FREE CORE IS DECIMAL 8828 ACCEPT STANDARD CORE? YES OR NO: YES PUNCH ABSOLUTE TAPE? YES OR NO: YES SYSTEM PUNCH DEVICE I/O ADDRESS? 13 HALT instruction 102077, P: 23420 (LIA 1) I have no idea what to enter in the "INFORMATION TABLE" so not sure that's right. Also not sure if my account information is valid. Running yields: sim> g 100 YEAR? 78 MONTH? 12 DAY? 12 TIME? 1212 YEAR? with then loops forever. Seems to be valid date info, but not sure why it's kicking me back into the loop. Anyone have docs on this? -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!
