What do you mean? You want more than 16 colours? That would mean Minerva would need a new GFX driver wouldnt it?

Re: How can I get a pixel color?

Hi,

8 bit colours? Is this 2^8 or 256 colours?

QL Mode 4 is 4 colours, 2^2 or 2 bit
QL Mode 8 is 8 colours, 2^3 or 3 bit

I wish there were 256 colours on a QL without SMSQ/E.

The Q68 can do 512x256 Mode 33

Re: PiStorm

Trying to find out how much the PiStorm board (Altera II Max) draws but the Pi Zero 2W seems to be pretty efficient for the power it supplies and is becoming the preferred choice for PiStorm boards since it's only slightly less powerful. https://hackaday.com/2021/11/01/the-pi-zero-2-w-is-the-most-e...

Re: CPLD replacement for ZX8301

Why does the CRT picture look so different? Because it is from the composite output that is produced by analog mixing the fourth bit signal with the RGB bit signals using 3 extra resistors, but If you mean the bar width this is a change I did in the test program. The LCD is from the unaltered stand...
