[cctalk] Re: auction starting in 50 minutes

I loved the machine room in the LCM. It was my favorite place in the museum. I had been a student operator of the machine room at my university in the late 80s. When I first walked into the LCM machine room I was instantly transported back. The sound, the all-surrounding light level from the

Nice! Years back I gave Dr. Jones my PDP-8/L, prior to moving out of Iowa. I wonder if he still has it, and put it to use. -mike -Original Message- From: William Sudbrink via cctalk Sent: Thursday, February 2, 2023 3:29 PM To: 'General Discussion: On-Topic and Off-Topic Posts' Cc:

[cctalk] Re: Computer of Thesus (was: Re: Re: Computer Museum uses GreaseWeazle to help exonerate Maryland Man)

I must have missed your offer for 8" floppies! Please let me know if you still have any. I was looking for some a while back, and mostly found them in the $5.00/piece range, which is just ridiculous. I finally just happened across someone in a facebook group with about a hundred to sell, fair

[cctalk] Re: Computer of Thesus (was: Re: Re: Computer Museum uses GreaseWeazle to help exonerate Maryland Man)

In a lot of ways it's entirely contextual, or a matter of practicality. If the goal is to just get the original operator/software experience, then emulators should do the trick. If it's about the original feel of the hardware, with all its limitations and warts, then stock hardware is the way

[cctalk] Re: Downsizing "feeler"

A friend of a friend helped someone out a few years ago who was in a similar situation, but with high-end audiophile stuff. Same general deal, tho - had a collection build with love and detail over decades but for practical reasons had to make it gone. The solution was to find someone also in

[cctalk] 8" floppy diskettes themselves (was: 8" floppy diskette storage cases)

With all the talk about 8" floppy diskette storage cases, I was wondering if anyone had any 8" floppy disks themselves they would be willing to sell? This winter I am hoping to start restoring an IMSAI 8080 I recently acquired, and while it came with one external 5.25" drive, it would be desirab

The folks at the Living Computer Museum + Labs in Seattle were working on a restoration of one of these, or another, similar Bendix machine. They remain closed (who knows if they will ever reopen), but there might be a way to find some of the people who were doing the work. -mike -Origina

[cctalk] Seeking Atari ANALOG magazine issue #3

I spent much of the pandemic focusing on filling out my 8-bit Atari documentation & ephemera collection, and have come pretty close to a milestone. I am only missing one issue of ANALOG magazine. Number 3 still eludes me. I've been on AtariAge and ebay and all the usual places. I know I can

[cctalk] Re: [cctalk]Can someone explain...

Yes, but yours wouldn't come with the oily grime of authenticity. Some people have too much ebay, and too little common sense. -mike -Original Message- From: William Sudbrink via cctalk Sent: Monday, July 18, 2022 7:56 AM To: General Discussion: On-Topic and Off-Topic Posts Cc: Willia

RE: Women of Computing

Ugggh, as soon as I saw this conversation I new it was going to be a race to the bottom. Actually, it was far less worse than I expected, so progress, perhaps? I've been frustrated by the lack of women in the industry, because there's no rational reason for it and it feels like we're wasting h

Interesting photos of a computer graphics lab from 1968

A friend of mine collects old photos, and sent me a link to this set he just recovered from film. He doesn't know much about the provenance, but it might be interesting to figure out what we can about them. The link is here: https://www.espressobuzz.net/Found/GeorgeClark/GraphicsLab/ The film

RE: Exploring early GUIs

There's also the windowing system used on the AT&T 3B1 (AKA Unix PC, AK PC7300), which I think was called MGR. It may have also been ported to other systems as well. When I had one of these machines it was adequate, although terribly slow on a 512K system. There's a writeup, with images, here

RE: Network gear that supported StarLAN 1 (not 10)

Wow. I ran StarLan 1 around my apartment in college, using an AT&T 3b1 as the hub and a collection of 8088 PCs with 8-bit ISA cards scattered around. I could rlogin (not telnet, from my recollection) from any of the PCs to the 3B1, and dial out through a 14.4 modem into the university network.

RE: Any interest in "newer" hardware, software?

A lot of the younger collectors are spending ridiculous amounts of money on 486 & Pentium class machines on assorted facebook vintage and retro groups. I don't get it either, but everyone has their fetishes and I try not to judge. Parted out you can possibly get a couple hundred bucks out of a

Years and years ago I owned a Lambda, along with a couple friends. I'm going to guess this was around 1993 or so, give or take a few years. It had been owned by Ames Lab at Iowa State University. We had it running for about six months and decided to sell it to someone I believe was in Madison

Hello! New member to cctalk here. I am located in Seattle, and in the past have worked for a couple largish companies in the Seattle area you've heard of. Through the 80s and 90s I had accumulated a fairly sizable collection of classic (and not yet classic) computers. Mostly this was along tw
