Re: Extracting files off “unknown” 8 inch disks. Any thoughts…

by terry＠webweavers.co.nz

Hi guys, Just tying up some unfinished business. Right at the beginning of this thread I said... >Guys in the building next door to me (a Science lab) have found some 8 inch floppy disks. >They want to see what?s on them, or at least to archive them. >They have no idea what machine these disks were used with, or the software was used to write the files. >They may be CP/M, or some other format entirely. Now that I've got the 8 inch disk drive up and running and have some experience with it, I thought I've give these disks a go. It turns out these disks are from a VAX machine. Assuming the OS is VMS, I scoured the Internet for something that might read them. Eventually I found Hunter Goatley's v 1.3 of Paul Nankervis's ODS2 at http://vms.process.com/scripts/fileserv/fileserv.com?ODS2 . This program reads VMS disks from PCs. The zip had a Win32 executable included. The executable seems to run ok in the DOS window of the Win98 machine I've attached the drive too, in that the Command Line Interface seems fine and I can type and issue commands. However, I've had no luck with mounting the disk in ODS2. The error I get (consistent over all disks) is: "Sector 1 read failed 87 PHYIO Error 500 Block 1 Length 512 (ASPI: 0 0 0) Mount failed with 500" I may have reached the limit of my skill envelope. Before I abandon the task and suggest to these researchers to consider sending these disks to Chuck C., does anyone know... 1. What that error means? 2. If it would make a difference that I'm running the Win32 exe in Windows 98, rather than NT, 2000, XP etc.? The documentation doesn't mention Windows 98, however the program does start to a CLI without a problem. 3. I'm not sure ODS2 was built with 8 inch disks in mind? Would it make a difference? CP/M disks in the 8 inch drive can be accessed and read/written to under MS-DOS by the machine I have the drive hooked up to, so I don't think it's a hardware issue. 4. How likely is it that disks from a 1985 VAX is in some weird proprietary format OTHER than VMS? Any comments most welcome. Thanks! Terry

ISO: Solid State Music IO-8 S-100 Serial Board Manual

by systems.glitch＠gmail.com

Just purchased a Solid State Music IO-8, apparently the manual is not available online, and isn't listed in Herb's documentation collection. Anyone have it? Looks like it's eight Intel 8251A serial ports. Thanks, Jonathan

AT&T 3B2 list

by alan＠alanlee.org

A few people on the Sun help rescue list raised interest for AT&T 3B2 community projects. So I've created a mailing list to help segregate traffic for detail oriented 3B2 related topics. Seth Morabito has invested lots of effort into adding WE3K chip set and machine emulation to SIMH. I'm interested in building some new CIO boards for the machines. I would also like to eventually mirror all 3B2 related information to 3b2archive.org. And other contributors and lurkers are signing up too. Please see details in the quoted message below.

Vintage computers for sale

by asc135＠gmail.com

A friend of mine was asking if anyone wanted an old CoCo 1 or 2, Apple IIc, TI 99/4A and one or two other machines he was looking to rehome. I realized I had several vintage machines that I'd like to rehome myself. We were discussing the possibility of collaborating on a vintage swap sale of some sort. Then he went ahead and created a facebook group to post pictures, etc. where he has some of his equipment listed. So I have a couple of questions... Is there already a well known online swap meet for vintage computer gear? (i.e. NOT eBay!) I'd rather not duplicate the effort and fragment the market further. If there isn't, I'll be putting up a few machines on my friend's facebook group at https://www.facebook.com/groups/448700415476109/ . I have a few TRS-80 Model 4's, a couple of Model I's, a couple of Model II's, a Cromemco Z-2D (with OEM labels on the face) which used to be a weather graphics computer), a couple of Columbia M64 Shoebox CP/M computers, and a few Coco 2's. The bulk of the people on the facebook swap group (including myself) are located in Central Indiana. I'll share the available computer details here on the list after I've done the writeups and taken pictures. Thanks and have a great day! Amardeep (a/k/a Marty, AC9MF)

Holmes Engineering DX-3D

by bill.gunshannon＠hotmail.com

Hey TRS-80 fanatics.... Anybody have any info on this controller? I have one but the controller chip is missing. And, I don't really know if it would work if it had one. But, if I could find out what the chip was and get one it seems this supported 8" drives as well as the usual 5.25". A user manual would be helpful, too. :-) bill

VCF-SE 5.0 Videos Uploaded

by alan＠alanlee.org

[cross posted] I was able to find time to edit and post speaker videos from this year's Vintage Computer Festival Southeast held last weekend in Atlanta. Amazingly I did it within one week and not a year or more! Here is the speaker summary and bios from the VCFed website: http://vcfed.org/wp/festivals/otherevents/vintage-computer-festival-southea… [1] And you can find the videos on the AHCS Vimeo channel: https://vimeo.com/user50868990 [2] Don French discusses the genesis of the TRS-80 Model I at Tandy/Radio Shack: https://vimeo.com/216109117 [3] Andy Hertzfeld from Apple talks Apple II and his journey to Cupertino: https://vimeo.com/216104204 [4] Zach Weddington hosts a special screening of his Viva Amiga documentary film followed by a panel discussion moderated by Adam Spring: https://vimeo.com/216081365 [5] Chuck Peddle via Skype discusses the history of the personal computer and his current projects: https://vimeo.com/216072422 [6] I've also continued to work on the 4.0 backlog. I've added David Larsen's discussion on the Bug Book series and his computer museum here: https://vimeo.com/216398748 [7] And as-posted from last year, Bil Herd discusses his early Commodore days: https://vimeo.com/161861581 [8] I still have Ray Holt, Jerry Mannock, Mary Hopper, and podcast videos >from 4.0 in my work queue. 3.0, 2.0 and 1.0 to come (Jason Scott, Robert Uiterwyk, Jonathan Zufi, Carl Helmers, Robert Tinney, Dick Huston, Dan Kottke, and others). But no ETA on finishing as of yet, sorry. There are some flaws in video (Andy's lectern mic - doh!) and audio (damn kids!), but they turned out ok. They are all open to free download. But please give proper attribution when sharing. On behalf of the entire Atlanta Historical Computing Society who work hard every year to make this happen, thanks and enjoy! We do this stuff for you guys!
