"what-if" QL extended graphics
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...

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

Re: Keyboard from where
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.

Re: ND-MQ - New Network Driver for the QLUB Adapter
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.
