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.

Re: Alienkid H5 C1 build
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.
still black screen, no idea why

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).
