Hey all, after a couple years of prep (weekends here and there), I've finally finished a full coverage video about the Sharp PC-5000. It's not the most meaningful system in history, but it also shows the "MS-DOS 2.0 experience" and bubble memory usage. Various folks around here helped me figure this system out and get some of the equipment, very much appreciated the willingness-to-help community here. Video is on YouTube titled as: Sharp PC-5000 and MS-DOS 2.0 Usage Demonstration (EDLIN, CTTY, MASM, BASIC, Pascal, WordStar, more!) Or link... https://www.youtube.com/watch?v=dHPiomuWDmk And to those who can't use YouTube for whatever reason, I've started also uploading over on Rumble as an alternative source: https://rumble.com/v6ybfky-sharp-pc-5000-and-ms-dos-2.0-usage-demonstration… I'll be at VCF MW coming up, hoping to pick up another system that I've been wanting to explore for a long time! Not sure yet it works, but that's how the hobby goes :) - Steve (voidstar tech / Xiphod)

Message trimming/formatting

by Marvin Johnston

There seems to be a LOT more people who don't believe in trimming or formatting their copies of the messages they are replying to. I see that kind of obvious disrespect for other readers, and ignored it for a while. But it is getting worse. Please format/trim when replying. Marvin

5155 lugable

by Bill Gunshannon

I finally got the missing keyboard and now it is time to try and revive it. A couple quick questions. It has a board in it called IBM PC INTERFACE with the numbers 170-18-165 and CIL18-16 printed on it. It has a 50 pin connector on the bracket end. If I take it out the machine dies almost immediately doing the POST. Tried Google with no luck. Anybody remember what it is? Next problem. 1701 error. Light on MFM drive flashes 3 slow and 4 fast continuously. Being as this machine was known to work when it was last shut down any suggestions? Could it be a stiction problem and the disk just isn't spinning up? (Can't tell by listening as the fan is pretty loud. Not bad just louder than any good disk I have ever heard.) And then one other not related to a problem. Being an original PC owned by users and not geeks is it likely that the floppy controller is one that can handle other formats (like TRS-80) and maybe even 8"? And just to wrap it up. What are the chances of finding an external drive or even a cable that could be made to connect to an external drive? Really hoping to get it to run. Would love to see what the Psychology Department had on it. At least WordPerfect as there is one of those function key templates taped on the keyboard. bill

We're getting off topic but I want to interject that if you want to see operating steam tractors, stationary steam engines, and lots more, get to Mt Pleasant Iowa RIGHT NOW for the annual Old Thresher's Reunion which starts TODAY. I note that when the Old Thresher's Reunion first started in 1950, the steam tractors being run there were only 40-50 years old, not too dissimilar to how an Apple II or PDP-11 is today. https://www.youtube.com/watch?v=hs4L2nSqCL4 https://www.oldthreshers.org/other-events/steam-school/ Tim N3QE

Tesla's Forgotten Founder Speaks Out - Exclusive w/ Martin Eberhard

by Kirk Davis

Interesting for Tesla’s early history, but skip to 49:00 for a nice rack he is putting together with an 11/20. https://youtu.be/88KHfX_kPIY He also appears to be on the cctalk list.

This is one of a few websites where ‘nice rack’ has a totally different meaning. 😊

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

Re: Chuck Guzis -- Equipment and Archive

by Gravity Loop

Hi Magnus, Thanks for the link but as I said, this is a field that is still under researched with a lot of misinformation out there especially on the less academic or lab side of things. I understand this stuff and the processes but I am here to help other people understand and acquire these skills for the future. The thing is, if he has custom equipment for it he may have also documented a reliable workflow that could be used in smaller operations, at home setups, etc. I'm looking to further disseminate information as well as continue the research outside of corporate interests. Making sure knowledge is handed off and widely available, including in print form. So while your helping spirit is definitely appreciated, as a professional audio engineer I'm explaining the state of things outside of lab preservation. Not to mention, you can read posts online by professionals even talking trash on the stuff linked. This is exactly how I found out about Chuck years ago. I'm chiming in here because I'm specifically interested in the knowledge Chuck collected, preserving any techniques he hammered into followable steps or additional knowledge not spread, and to share in more ways for others that didn't liaten or haven't figured it out yet. He was someone who knew a lot of tricks and helped a lot of people. - Lichen
