Alpha Rom from Angel Martin
Message #1 Posted by PeterP on 22 Dec 2005, 12:14 a.m.
Hi,
Just wanted to check if anyone of you has done some investigation of the functions of the Alpha-Rom? I have tried to come up with the functions, and got stuck with a few. Anyone has some ideas? (simply could not hold my curiosity until the arrival of a QRG... ;-) )
Here is what I have so far (sorry for the bad format...)
Cheers
Peter
