Thanks for confirming the myth with some facts. Sounds like the same sort of explanation I was given.

Seems odd Commodore would sell you a 14mhz 020 that can never run at anything like 14mhz oops....

The speed impact on CPU of ZERO Fast RAM A1200/CD32

I have heard many times from some people that without Fast RAM the CPU is blocked about 50% of the time it could potentially access Chip RAM.

Is this true, more specifically is it true regardless...

Yeah I agree, No Second Prize on the ST seams to be very smooth indeed and that's just as awkward screen memory to write to and only an 8mhz 68000.

An example of AGA sprites in OutRun

I took some source graphics from the coin-op because I was curious what you could do with AGA sprites. The palm trees needed to be trimmed down a bit to 64 pixel width but they don't use more than 13...

A question about AGA sprites

Which AGA games used the 64 pixel wide sprites?

Although it took Amiga a long time to get decent sprites with AGA I can't think of any games off hand that used those massive 64x[screen height max] pixel sort of sized sprites off hand.

Anybody?

Not an entire machine, two A2000s went bad about 2 decades ago so the motherboards were chucked. Gave the cases away and kept the mice and keyboards and hardcards/RAM boards.

Commodore could have done an A1200 bundle with that 1220/4, 28mhz EC020 pretty similar to 25mhz EC030 for most games but much cheaper. Think it came out just as Commodore was pulled under though.
