Hi AlicePPC!

I cant provide any of the items, but just for my own knowledge, how does exchanging the oscillator help? cant you just switch PAL and NTSC in early startup menu ?
 
Hola Miru.
I think for video purposes i need have the correct cristal oscillator

Hi,
I dont have any of these but heres a bit of help:

The ABT16245 is a standard 16bit version of the 74245 and can be bought from lots of places, look at your regional electronics shop like:

The CPU connector is hard, either take it off a dead board or email Jens.
Same goes for the crystal, get it off an old board because its an unusual frequency. (Maybe someone has a dead A500 on here?)
 
For the 200 pin CPU slot AKA "KEL from Hell" :LOL: (those found in the A3000 & A4000 an their T counterparts) in either male and female types are this ones (200 pin type):

Still being made and are RoHS compilant but I figure that you should state a minimum qtty order upon request, as normally those companies do not supply low quantities to individuals (maybe a collective order is a solution).

Hope it helps.
 
@AlicePPC:

If you can tell me the spacers measures i can try to send you similar ones free of charge, have lots of them from different measures.
 
All items found.....only left the bolts for mediator waiting for know the measures
thx to all
