128 x 32 EVO on DE 128 x 16

[SpaceGambler]

Hi guys

Just wondering if a 128 x 32 EVO will run on a DE 128 x 16 game with the 128x16 DE display driver board or is the 128x16 DE display driver board only for use with the Nucleo board?

Cool, thanks for that

Saves me getting a run of boards done for a 1 off

With the driver board and display connected on a bench power supply does the driver board display the ROM version on startup just like the original does or does it need a signal from the machine to do that?

You need to set your pin2dmd to DataEast128x16. If you have a TMNT or CP ROM you also need to set enhancer to false.

You should get the ROM version if you make a connection between GND and RESET pin on the DE controller input.

Nice, worked a treat.

I only had Z80's on hand, will that be OK or do I need a Z80A?

They are China eBay cpu's and the first one did not seem happy and was getting hot, the second one seems ok so far.

Looking at the clock speed you could have give the answer yourself . Z80A !

Z80 has only 2.5Mhz
