- The A3000 has got the DblNTSC and DblPAL modes, yes, on the
- ECS chipset, ... _B_U_T_ ... You are limited by the number of planes
- you can use in those modes ! The AGA chipset doesn't offer any real
- new modes, only increase in bandwidth, which is translated into more
- colors (HAM8 is just that : more colors, although you could see it
- as a new mode. Personally, I don't !) Oh yeah, the promotion stuff
- on the A4000 sucks ! If you really want promotion, get PKludge !!!
