I managed to get HP-UX to boot on the HP9000/370 in the Virtual OS Museum on macOS, but running under two emulators, it’s unfortunately way too slow—I barely managed to type in the uname command.
I wonder whether it’s any faster with MAME running directly on macOS…

Vor einem knappen Jahr habe ich von einem Bekannten einen A500 nebst einem großen Pappkarton Disketten und ein paar Büchern übernommen. Ich war lange unschlüssig, was damit anfangen. Vor ein paar Tagen dann der Entschluss: wird über die nächsten Jahre gemütlich vor sich hin restauriert und modernisiert. #vintagecomputing

On a blueish towel lies the CD box sets of Phase 1 and 2 of the BBC Radio series of the HHGttG, behind it is a reel-to-reel tape box with HHGttG hand written on it; it has the radio series recorded from it's original broadcast.  In front is a box of Ferranti Computer Systems 5.25" disks.

Been working on a Toshiba Satellite T1910 (vintage laptop) which had a dodgy floppy drive. 2 drives and 2 goteks later I've worked out the issue was the flat ribbon cable I was using! 🤦‍♂️ Needs to be the twisted type; pins are reversed. Will defo write this up for other poor souls when I'm done! #retrocomputing

#RetroComputing an old #SunMicrosystems buddy in New Jersey is cleaning out his basement collection of (mostly) working systems Ultra 1, Ultra 10, V210, V65X and Cobalt Cube. He says the only issue could be the drives on the V65X. Anyone want to go and get anything before they go to …

Anyone familiar with DOSBox and crashes of Windows 3.11 apps?
This app installed fine but it's throwing this. I tried a few different CPU settings in DOSBox but it happens regardless if it's a 486 or Pentium or whatever.

My beeb series 7 was having heat problems, so I bodged some heatsinks onto the CPU and onto the infamous 245 next to it (which was getting well over 50c in a few mins)
The series 7 case has the back vent mostly covered to stop junk going in.
Hmm the wire ties aren't really satisfactory.

What *should* a floppy drives read data look like (5.25" single density, BBC DFS) ?
Both my Model B and a greaseweazel are failing to read the two disks I've tried at all at the moment; does this stream (off pin 34 on the interface) look sane? I don't currently have a known-good one to reference.

Auf einer meiner Folien hatte ich meinen ersten Computer, den KC85/3 erwähnt und dann stellte sich heraus, dass im Archiv der Schule noch genau ein solcher Computer zu finden war, und zwar mit ordentlich Zubehör und Software.
Da habe ich nicht schlecht gestaunt !!
Heute hatte ich keine Zeit, aber ich will gerne wiederkommen und versuchen, das Gerät nochmal in Betrieb zu nehmen.

Just typed in a RAM test program on my Series 7 BBC Model B - it passes clean; hmm - doesn't explain the instability then.
Also, I don't seem to be able to (reliably?) write to a floppy - hmm. save file, *. and find it's nto there. Hmm. Tried formatting and it's verifying bad. So some more debug todo.
(Also, hth did I type so much on a Model B keyboard, the keys are HARD)

This prediction from The Micro User magazine in January 1985 about where home computers might go, and how computer-touchers might still have different attitudes than the rest of the population, turns out to not actually be a thousand miles short of the mark.
