Thanks! RE:XT Diagnostic ROM and POSTcard

by lynchaj＠yahoo.com

Hi All, I just wanted to say "Thank you" to everyone who helped me fix this classic IBM XT motherboard with the Diagnostic ROM image and the settings for the AWARD POSTcard. Long story short, I replaced a 74LS245 and a faulty DRAM chip and now the board boots fine. Of course half the fun is finding what actually works, what doesn't, what appears to be broken but actually works, what is broken but appears to be working, etc. You know the drill, I am sure. Fixing an old broken 16 bit VGA card which works in an 8 bit ISA slot helped a lot. As did the old style PC/XT style floppy drive controller... So anyway, it's fixed and I booted MS-DOS 5.0 and the Advanced IBM Diagnostics from a 5.25" floppy disk drive. So I think we are there. THANKS! Andrew Lynch PS, BTW the XT Diagnostic ROM image seems to work best when burned into a 2764 EPROM. I tried various other types of EPROM but the 2764 seems to work best. I think IBM did some weird remapping of their custom Mask BIOS ROM...

DEC Brochures - already scanned?

by aek＠bitsavers.org

> Wow, that must have been a brutal scanning job. Paper cutter and a sheet feeder. Biggest challenge was dealing with thin paper. I've switched to a different brand of scanner that can handle it better now to deal with the data books.

DEC Brochures - already scanned?

by silent700＠gmail.com

Last night I picked up some DEC equipment, and with it came two brochures and a book. The book I will probably list on ebay eventually, but the brochures I would like to scan and contribute to Bitsavers and/or anyone who collects such things and is willing to host the .pdf files. But before going to the trouble of scanning them, can anyone tell me if it has already been done? One is for the VT52/DECScope, and the other is for the 11/70, both with many lovely photos: http://www.flickr.com/photos/chiclassiccomp/2537619814 http://www.flickr.com/photos/chiclassiccomp/2536801495/in/photostream/ The book is the "dos/batch handbook" and appears to be from 1974. It is truly massive, like city phone book-sized. I've never seen a DEC manual this large. I won't be scanning this one ;) -- j

buying an oscilloscope

by gerhard.kreuzer＠liftoff.at

Hi first of all, I have one, you can get it, please let me know. Its a 100MHz, two channel scope with second timebase for magnifications, but?its analog not digital. For slow signals usually present in classical hardware, thats no problem. And you also could look at www.testequipmentcollection.com[1] I bought my 'new' one there. (350Mhz, Hybrid scope, 2 channels + 16 digital logic analyzer). I also collecting classic computers, take a look at www.tuko.at[2] --> Computermuseum. With best regards Gerhard Links: ------ [1] http://www.testequipmentcollection.com [2] http://www.tuko.at

Their website explains it all succinctly: Well, in point of fact, there is a website that explains what we are doing in a great deal of detail. Maybe it's not as much fun to know that. http://www.pdpplanet.org/ I signed up for the cctalk mailing list on 29 April, in order to post the job offering among a community that might actually match up with the job requirements. The "Welcome" message was not sent back for 30 days. In any case, those interested in working on a large, and growing, collection of vintage systems should go take a look at the Vulcan jobs website: http://jobs.vulcan.com/default.cfm?szCategory=JobProfile&szOrderID=1541& szJobCategory=15 We're still interviewing.

Electronics Today International (ETI) "System 68" firmware

by Nick.Jarmany＠quixant.co.uk

Does anyone out there remember the "System 68" project that ran as a series in the UK magazine Electronics Today International (ETI) during 1977? I built this when I was young, but unfortunately all my early hobby stuff got slung out when my parents moved house. I have managed to re-create most of my "lost" issues of the magazine, including the ones covering System 68, which was a simple M6800 based system with a memory mapped VDU. Now, here's the question - does anyone out there remember this project and, if so, would anyone happen to have a listing of the monitor firmware? I believe the firmware for this system was derived from the Motorola MIKBUG monitor, modified to suit the different hardware. I want to re-building this system, but so far have been unable to locate the necessary firmware. Hoping that there is a someone out there that might be able to help out! Thanks Nick

Available: Sharp ZQ-5200 Organizer

by alfred.galea＠onvol.net

Hello Dave, I think it's a long shot, but do you still have the Sharp zq 5200? More specifically, I am looking for the owner's/operations manual for it and have had no luck with surfing, not even on the Sharp Electronics site. Maybe you could point me towards a more fruitful source if it is no longer with you. Kindest regards from sunny Malta Alfred
