Original SHARP chips with TOS 1.02 (28 pins)
New eprom Chips with TOS 1.04 (32pins)
I have tried to do it for my Mega 4 but I only achieve a white screen with slightly yellow borders.
I have done the following:
TOS 1.04SP burnt in 2 27C010 EPROMS. The original TOS .IMG file had been splitted in two files (HI and LO) using Hatari and Ppera ROMSPLIT.
Because it will be in a Mega ST and there is lot of free space I have used two 32 PIN socket per chip. So the images are here:
Mega 4 orignal roms (1.04 German)
But it doesn't work....What I have done wrong???
This is wrong. Use the 27C010 and engage follows. https://docs.google.com/file/d/0B16K0oc ... sp=sharing
