It's not your fault, it's almost certainly a side-effect of one of Alex's changes to the main LisaFPGA code. His change revealed a bug in the Selector (the program that boots and gives you the hard drive image menu) that is almost impossibly unlikely to occur in a real Lisa, but that easily...

Come to RetroFest in Swindon next June. It's not the size of a modern-day VCF, and it lacks talks (which I regret), but it's a bunch of folks showing their retro machines and projects. Has been going for several years. I'm guessing it's a lot like what VCF was like in years past.

Cross-posting a follow-up from me on 68kmla: Last night I succumbed to temptation and asked a robot about this situation. It too picked up on the TS partition map [note: a 68kmla commenter had pointed out the fact that the disk is using an older style of partition map], which, although not a...

(Crossposting from 68kmla as the BlueSCSI website advises coming here) I have a puzzling BlueSCSI situation on my long-suffering Mac Classic. The Classic works, the original HDD works, and the BlueSCSI works, but the BlueSCSI will not boot from an image of the hard drive. The Classic: An...

I've now tried the games on a real Lisa 2/10 and observe identical behaviour. ETA: I had a hypothesis that switching to "square pixel" mode would fix LodeRunner. It did not. I am barely competent to complete the first level of LodeRunner and so this data gathering has been somewhat slow!

(All experiments below are carried out on a LisaFPGA run at the ordinary Lisa CPU speed.) When I try to run Asteroids, a dialog says that the application unexpectedly quit, the screen gets corrupted (desktop goes black but window refreshes work), and the mouse disappears. I'm able to get past...

I don't know about the games, but it's no surprise to be missing sound: the stock Lisa never had sound hardware like the Mac does, and to get sampled audio out of the machine requires either a special expansion card or considerable effort in software..

I've been there in the other direction. The flat's main breaker tripped before too many components got blown out.

Gerbers are here, or so the filename would suggest: https://github.com/alexthecat123/LisaFPGA/tree/main/hardware/lisafpga_deaktop/rev_3

The New Ken museum is one of the best computer museums there is, I think; it has an amazing collection, and I visit whenever I am anywhere nearby. You are lucky to live so close! There is not a lot of Mac stuff in particular; a couple Macs and Lisas in the micros collection. The most impressive...

You know about the museum in New Kensington, right? I lived in Pittsburgh during the G20 (which was 2009, so a little while back...). All the buses set up their signs to alternate between their route number/destination board and "PITTSBURGH WELCOMES THE WORLD". I got a chuckle at seeing an...

Nothing in a hurry :) For all of its quirks (and if you overlook its slowness) it is a pretty straightforward BSD 4.3 workstation with a graphical windowing environment (not X though; it's its own thing). It has an AUI ethernet port on the back and will speak TCP/IP, so during COVID...

Not many people talk about the Whitechapel MG-1 workstation, or about the NS32016 CPU that powered it. That's probably one of the more obscure items in my collection. Whitechapel stuff isn't even on Bitsavers despite some very low-effort lobbying to get it there.

Well, there aren't many cases where I'd be more delighted to be wrong. I wish you the best of luck.
