80386 - 1985

by Murray McCullough

40 years ago this year Intel came out with the 80386 – 386 – or i386. Either seems to be correct. What this meant was a memory address of 4GB, far beyond what an average computer user would need or want, but was so much more than previously(8086, 80286); ‘true’ multi-tasking which for the average computer user didn’t mean all that much; and paging, which made virtualization possible- experimenters were over-joyed! What all this contributed to was the end of the classical/vintage-computing era. Whether this began the time of open-source OS development is debatable! Happy computing? Murray 🙂

Anyone used a M5C6847 in place of a MC6847?

by Jim Brain

I have a tube of them here, but they won't do anything in any VDG-based system here. Wondering if it's just broken parts (I have no record of buying them, so must have been someone gifting them to me) or there's something I am missing: http://matthieu.benoit.free.fr/cross/data_sheets/M5C6847P-1.pdf -- Jim Brain brain(a)jbrain.com www.jbrain.com

Me again! RSX-11M manual set

by Peter Ekstrom

Ok, it's me again with another RSX-11M question. I have a nearly complete set in PDF form for 4.2. But I am running 4.8. Is 4.2 close enough or does anyone have a set for 4.8 or maybe even 4.6? In searching around on the 'net I have found a release notes doc for 4.8 but that's it. Thanks! - Peter

Chuck Guzis -- Equipment and Archive

by Chuck Guzis

I am Michael St. Clair, Chuck's nephew by marriage. I'm writing from his account to establish bona fides; apologies for any surprise it might cause. You appear to be the people he considered his professional peers, so I'm reaching out to you for some help. Chuck had little warning before he passed. He left his equipment and development environments in working order, but without a legacy plan. I'm a software engineer and data archivist, and my aunt has asked me to find good homes for his equipment and IP. I'm going to organize and open-source the software and other IP that he hadn't already released. However, I don't know how to safely use, maintain, or even store his physical gear. I'm only in Eugene for a couple more days on this particular trip. is there any specific physical information (that doesn't require disassembly) that might be useful to potential adopters? I don't have time to make a complete inventory, but here's a list of highlights and a Drive folder containing some photographs. This is not (yet) a formal "come and get it" offer, but it's likely a prelude to one (excluding business documents and computers). Highlights: - Multiple 8-inch floppy drives in built-like-a-truck housings - Dozens of assorted 80s and 90s-era I/O devices -- ZIP drives, 5 1/4" readers, etc. - rack-mounted HP 7970B tape drive - another full-height rack-mounted 9-track tape drive with external control panel; no manufacturer or model number on anything I can get to - custom-built 'tape dehydrator' - around a thousand pieces of assorted removable media, primarily 3.5", 5 1/4", 8", CD, DVD, and a variety of late-90s and 00s digital tape formats. Per labels and spot-checks, their contents range from widely-distributed commercial software to Sydex master floppies to lost BASIC dialects to industrial control software in CP/M formats. Basically 25 years of Chuck's professional life and the industry around it. - full electronics workbench with partially-finished projects, including something involving Pertec controllers - a variety of functioning vintage keyboards, from IBM Model Ms to something apparently taken from an industrial control station. Drive folder: https://drive.google.com/drive/u/1/folders/1KUs-x6t4OtzS_b7lxYMM7i-GxNi-QRv3 I'd very much appreciate any input. -- Michael St. Clair
