That's worrying @PhilC as I have one of those as well... recapping the two Beeb model Bs and ancillaries is way down the hobby priority list at the moment though :( :roll:PhilC wrote: 24 Feb 2024 13:17 @stephen_usher you have my sympathies. I’ve been working on an Opus Challenger 3 in 1, got the ram working now but the drive spins up but doesn’t step whilst trying to format or read.
Don’t worry too much Jez, it’s probably a cabling issue or a problem with the Beeb as it’s used on the 1mhz bus and this Beebs never used that before. I think the drive is fine as I’ve substituted it for another. Some of the ram was faulty though and only intermittently detecting the second 256K bank.JezC wrote: 24 Feb 2024 14:39That's worrying @PhilC as I have one of those as well... recapping the two Beeb model Bs and ancillaries is way down the hobby priority list at the moment though :( :roll:PhilC wrote: 24 Feb 2024 13:17 @stephen_usher you have my sympathies.

It's almost like they want to die!!!stephen_usher wrote: 24 Feb 2024 13:07 More shenanigans with the Kaypro drives this morning.
Drive B's motor decided to run full speed whatever I did, even replacing the LM2917 on the servo control board.
I'd already reflowed the solder on the connector, which had cracks. So it was a case of buzzing out traces.
Found that an old bodge to repair where a capacitor had been pushed through the board and pulled the trace off the board wasn't working any more. It was extremely ugly anyway. So I removed it, put a proper bodge wire across the board, secured by hot snot, and resoldered the leg of the capacitor to a better piece of the trace.
That worked.
Put everything back together yet again... and Drive A started playing up. *sigh*
Not yet, but I'll try it at some point in the near future.stephen_usher wrote: 24 Feb 2024 19:29 Ah... non spinning drives... did you try giving the motor a it of a push? Works for my Drive B. :-)
Yeah, apparently 7 hour drive round trip.PhilC wrote: 24 Feb 2024 22:00 Ah so you’re venturing into Norfolk for the old Apricot.
And great that you’ve done a history for the machine you’ve repaired. I like to do that too sometimes. At least little hints here and there.
