You're in the UK right? Do you want me to have a look at your H5?

It depends on how old the ROM is. TOS104 should be closed.. But best to check the ROM in a programmer to see which way round it is.

cheers, i'll keep looking today.


the solder on the 4 sockets is perfect, i noticed 2 or 3 of the pins on cpu were minimal, but sorted.

Hey,

I'm the guy who sold you the RAM board! :)

I can send you my spare working 4MB RAM board to double check if you like?

(They were both run before being replaced with the 14mb, but you never know).
