I like the fact that my tiny little Kindle charger far exceeds the 5v 1A required minimum. When I think back to the concrete block that was/is my QL power supply!

Cheers,
Norm.

Not that the Q68 requires 1A. That is just lots of extra current for external devices that might be connected.

Without external devices, the Q68 board consumes only 0.15 A.

Thanks Peter, in which case, my Kindle charger really does exceed the required power needs!


Cheers,
Norm.

I hope to be able to write more about the Q68 at a later time, right now let me say thanks to...

... Laurence Reeves and Tony Firshman for releasing Minerva as free QL operating system, motivating me to develop the Q68 at all
... Richard Zidlicky for bringing Minerva plus PS/2 driver to the Q68 and his great help debugging CPU cores
... Mark Swift for QDOS Classic, structured so nicely that even I could port it to the Q68 in a single day
... Tobias Gubener for the CPU core the Q68 finally uses
... Adrian Ives for the QL-SD driver, initially used for Q68 mass storage
... Tony Tebby for relasing SMSQ/E as free software after all
... Wolfgang Lenerz for his outstanding achievement of porting SMSQ/E to the Q68
... Wolfgang Lenerz again for very helpful tools, extra drivers and docs
... Derek Stewart for his courage and lots of work manufacturing the Q68 hardware and making it available for the public

Hi Derek,

This is great and compact design. Is it an FPGA implementation? I remember you announcing 'Verilog' intensive course self study in connection with ZX8301 - ULA reengineering, so this is the result probably.

These modern designs are simply beyond my skills and capacities. Again, very well done.

Hi Tomas,

I wish this was true, but I do not have the programming skills to develop the FPGA core, my only input into this is producing the Q68 from design specifications.

Peter Graf has developed the Q68 FPGA core that emulates a 68000 CPU.

Peter should be congratulated for the amount of work he puts into producing the high quality hardware.


Regards,

Derek
