WIN 95

by Murray McCullough

Microsoft released WIN 95 on this day 30 years ago. It was a game changer for the average PC computer user but more important than Windows 3.1? Not so sure. Happy computing, Murray 🙂

The Sharp PC-5000 Video

by Steve Lewis

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

I don’t think that was an issue really solved until gas > powered tractors came around. 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. 😊
