Matrix 6r Rom 1 and Rom 2 chips?
2008-08-31 by zog2zog2003
Inside my Matrix 6r, next to the OS chip, there are two vacant places of the same # of pins, labeled ROM 1 and ROM 2. One of them has the holes filled with solder; the other has a socket. Does anyone know what they're for? Maybe future expansion, or something that the keyboard version uses?
