Re: TF534 on CDTV
Nope it just tries to boot and crashes.
It does the same with the same ROMs in WinUAE. So i need to wait til the 27C1001s i ordered appear.

Re: TF534 on CDTV
Yes, 27C301 are good, i just worried about speed - chips i saw was 200ns, i got issues with kickstart rom when i tried to use 150ns, so i think we need something in 120ns range...

be careful if You use TL866, it doesn't support 27C1000 directlyterriblefire wrote: ↑Sun Jan 27, 2019 12:32 pm OK this guys is getting some attention today.

it doesn't report errors, so You'll get impression it's burnt correctly, but it's not!
2 & 24 need to be swapped, and burnt as 27C1001
