I have 128M on the motherboard and 128M on the Cyberstorm3.
Aftermarket hack to get 128MB on motherboard? I've heard rumors of those. Most only support 16MB. You sure about 128?

I don't know why Commodore continued to cripple their machines with such poor memory access. No fast mem on the A1200 or CD32, slow access on the A4000/4000T, etc. Oh well, just a few in the long list of dumb decisions. Aside from the finger-slicing case and mediocre airflow the A3000 really seemed like the best of them!
