the Qzero has become much faster in the highest graphics resolution. That is possible because the Qzero FPGA now supports the separate video RAM, which was already present on the board. In 1024x768 @ 65536 colors, the Qzero is now about factor 2.6 faster than before, according to the BogoMIPS and Dhrystone benchmarks.
Side note: Qzero supports the Minerva 2nd screen, which requires the address range $28000 to $2FFFF to be treated as video RAM. This region ist therefore slower than the other SDRAM, which takes away a little from the theoretically possible improvement.
Those who have a Qzero should have received the FPGA logic update by email.
For others who are interested: I'll demonstrate the Qzero at the international QL meeting May 17.
All the best, Peter
