Seems, that your Memory mapper, or computer is broken. Have you tested
that mapper in an other slot / other computer ??

It should be easy to update A1WX to 256Kb, because there is free plases
for extra memory inside. I think, that you have to just put certain RAM
chips and condensators, and it should work. I have one A1WX, but I managed
to blow it up =( Now I use only its keyboard in my tR, and I think,
that I'm only one, that has black keyboard in tR =)
BTW did you know, that you can run your computer in 7Mhz, if you write :
OUT &H65,0 in basic, if I remember right. It was maybe &H64 Test it. You
can hear the difference, if you press ^G (beep)
