Re: Minerva ROM hangs on start up
The only thing is - to get to that screen it must have done the memory check and passed it and reported 128K

Re: Minerva ROM hangs on start up
Possibly nothing to do with the issue, but there is no red in your picture - which seems a little odd.
As XorA says - keyboard membrane, or possibly IPC chip or the Zx8302 chip not communicating - so the keypress isn't getting detected.

Re: "what-if" QL extended graphics
I've been following that one - he was inspired by the earlier KIWI 68K project from Germany, which used the incredibly rare V9990 MSX VDP with the version MSX3 specification - which could drive VGA directly. No one ever has stock of the chip and whenever examples do surface they are snapped up very ...

Re: "what-if" QL extended graphics
The only down side of the Yamaha VDP's is that they are accessed over an I/O port to update their own separate VRAMS with your display data. Whilst they do offer some forms of DMA operation - this won't be easy to setup on the QL side. A bitmapped display is probably a better way to increase the res...

Re: Bletchley Park / National Museum of Computing
Tommy Flowers needs more recognition than he got/gets. Disagree at your peril! ;) Cheers, Norm. You won't get any argument from me on that one - he did eventually get a little recognition and a road named after him, but the guy was truly visionary to have put into physical form the concepts discuss...

Re: Rich is in the news!
Good article!
It's interesting to see that industry still has a requirement to keep some retro gear in a running state. It's amazing how many people take backups on older media and then don't keep the hardware around to actually read them again

Re: New Forum
Well - that's different but similar to the older forum look and feel - I had not noticed over the weekend due to being at work, and not on the following 2 days either - but this looks crisp and bright

Re: RAM fault rabbit hole
The video is produced from the lower bank (in address range) of RAM chips and will try to happen whatever. However - the ZX8301 is also doing address decoding for ROM, RAM and part of the I/O - so if the chip isn't doing anything - it could be duff as Chr$ says. Usually, if you have a missing track ...
