Hi buddy, as above i can erase, blank check and program by resetting the cable between each operation but verify fails every time. I will test if the card is working later but for now i've pushed it to one side :)

Ok so it programmed but I was unable to verify. Got round to testing it today and it boots, ram is present and IDE is working. I do however have a small issue if anyone has any ideas.

I have a 4 in 1 (27c160) EPROM tied to an stm32 blue pill board as a ROM switcher. The issue I have is when I boot with the tf536 connected there is a flash of rainbow colours on screen then black screen and it stays there stuck until I cycle to a different rom on the switcher, once that cycle is done it will working fine till I power off and back on.

Booting with a standard 68k doesn't do this it just boots fine.

Any ideas or should I just burn a 3.2.1 ROM and move on instead of having a switcher?

Thanks
