Am I right to assume that if you were to add more memory and a FPGA there would even more colors be possible ein Mode 4 and 8 and that this would rather be a 'graphics card' instead of a replacement board? Yes, and as an aside (I don't mean to hijack this thread) I started writing something like th...

I may be wrong, but wouldn't that have required 8 more inputs on the ZX8301? That would also have been expensive.

Hi Derek, have you tried the link earlier in this thread to the old PPC version?

Are you sending the long gap of zeros between sectors? ZX8302 should detect it and generate an interrupt for the CPU.

Cool!
(I wish I bought a PCB when it was available.)

You just described my problem & why I just lost the will to live. It would take ten times longer to assimilate the information than to design & implement the code. There must have been a design specification for the part but I suppose that was thrown out with the cat when Sinclair went toas...

Is there a concise specification of the other functions of the 8049? I had a look at the Hermes stuff but can't understand enough to code a PIC for the other functions. Apart from keyboard/joystick, the 8049 generates sound and handles the receive part of RS232. Plenty of info in the QL Service Man...

Very nice! I didn't know that it was possible to compile C++ to run in a browser.

Serial ports are not supported on the Mac version of Q-emuLator, they are only available on Windows. They used to be supported pre-OS X, but then the OS and APIs changed and Macs no longer had hardware serial ports.
