The Sinclair QL Forum

The only thing is - to get to that screen it must have done the memory check and passed it and reported 128K

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.

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 ...

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...

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...

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

Wasn't ingot21 the last release of that?

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

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 ...
