The problem seems to be with finding a gamma as for some reason there seem to be very limited sources around. Personally am lucky (or unlucky?) to have as many as I want due to a contact in Germany so am kinda experienced with them.
Tip: Always program them at 6mhz and dont play too much with them or they will die(no atr)
