Have replaced the sockets, now two quality sockets with round contacts are in.
Still with these it doesn't work either.
However it was a very good idea.
Doesn't make much sense.
I would check the CE and OE pins on the ROM and make sure they are switching.. maybe broken trace/bad glue socket, from GLUE to ROM for chip enables, you changed the LS11 already.. but I think you should check the ROM select lines from GLUE to ROM sockets.
If TOS206 worked on another board, then onboard TOS104 isn't working, GLUE does decoding for that...
