The CPU max about 64mhz but likely be 50mhz for normal usage. Anything above 50MHz is down to "overclocking" and I doubt people will get much past 64MHz there.

Edit.
https://www.exxosforum.co.uk/forum/viewt ... 510#p32482. Couldn't get past 75mhz, needed freezer spray at that point :lol:

OK i'll put a 120Mhz crystal on there and be a sneaky SOB.

In regards to the original 16MB find from @exxos we could test it out with a modified Three Amigos board on the H4 as pointed out the H4 has a SIMM already and waiting for a MAD10 line.

I just threw a PLD in between the GLUE Socket and Connector to get the MAD10 line out with a few other IO's for testing as well.

So this will give us 14mb then?

In theory yes. Doubt it be that simple though.

I dropped the ram board before i got sick i'll pick up again.
