I think for PETs the sleekest solution is SFD1001 which looks like an OG 1541. I think disk format wise it is like an 8050 or even 8250. But I don’t know how many of them were made.
I'm certain it could. As I mentioned in the video, start with just re-seating all the socketed chips. Check for 5V and 12V on the board. Are there any blink codes? Does the drive mechanism spin up? If you pick up a chip tester (backbit or retro chip tester pro, etc) you can also pull and test all of the chips. Good luck getting that working!
Indeed. It was also pointed out to me that it's BASIC 4 so I could have used the fancy header command. Good feedback, though, so thank you. Also, your comment means you actually watched that much of the video, which is awesome!
I only resort to using soap and water if they're really dirty like this board was, but I've been doing it for decades and not yet had a problem. For less dirty boards I use alcohol and a cotton swab. This 2031 is still working great.
I have a drive just like this...and it flashes once...and the motor keeps spinning...the documentation I have been able to find says simply...ZERO PAGE...but I can not find anything that would tell me what that means...I have swapped out the 6502 and the 6522's into another disk drive...as it happens, and 2031 LP drive...and they all seem to be working just fine...I am pondering swapping out all the RAM...but am still quite puzzled about the reference to ZERO PAGE...Got any suggestions, insights?
Nice cleanup! It would be cool to see the similarities and the history of the 1540/1541 as it relates to these PET drives.. Keep up the good work.
Great video, nice restoration :)
Thank you very much!
That was so satisfying. :)
8:03 "Made in USA"...I remember those stickers! You hardly ever see them nowadays ☹️
Nice work. :) TBH I'd rather have a 2031 than that giant 8050 I've got here even though the capacity is much smaller on the 2031.

@@mudi2000a Sleek perhaps but problem-prone. The mechanism needs recapping, and those RRIOT chips go bad.
Nice work, but Commodore stated in the manuals that you should not use oil as a lubricant. You need to use molybdenum grease.
Good to know! I had nothing around other than common motor oil so I borrowed the sewing machine oil from my wife. I have to order some proper grease.
I have a non-working 3040.. wonder if it can be fixed...
It "hangs" on commands :(

i:0 is initialize n:0 is formatting

Great video. Were there any long term problems cleaning the motherboard with soap and water?

Zero page would likely indicate the on board sram
A serial number over a million. As rare as they are I doubt they started at zero...
Guessing that one was a generic prefix, but I don't actually know.
