So guys (and girls ;-)), i got the 330 ec020, i'll put them in a a500 and a600 accelerator with 4MB SRAM (for the price, and speed gain, I think is worth over dram).

I would be so happy if we could have another accelerator for the A600!!!!  :banana:

I would certanly buy one  :-D  :-D  :-D

IMHO a 14 mhz 68EC020 is great + add 4 mb ram. Also it is possible to add an additional 1 MBytes (or even 1.5 Mb) of ram by mapping it into the $C00000 space without disabling the PCMCIA. It is the old "Ranger" memory used by many A500 expansions. Obviously the RAM would be just as slow as chip RAM, but hey, it's better than nothing! This technique was also used by one A1200 accelerator, can't remember which one though - I could look it up if anyone's interested.

So in theory one could have an A600 with 2Mb chip, 4Mb fast, 1.5 mb Ranger = 7.5 Mb ram and still a functioning PCMCIA, not bad, eh? :-)

A 68020 is awsome because it does not require a heatsink/fan!!

I'm all for the 4MB of Static RAM soldered on board. It would be a nice speed boost for the 68020, also it would be nice if you could clock it at full 16 mhz instead of 14 like the A1200.

The original Ax00 should only be accesed in the following mem areas:

0x000000..0x1fffff
0x600000..0x9fffff (A600)
0xbfd000..0xbfffff PIA (even addresses)
0xdf0000..0xffffff

How about mapping some memory to the 0xC00000 on the A600 as I suggested? This would allow you to increase the total system RAM without interefering with the PCMCIA, not to mention that it would improve compatibility with some old games on the A600. :-)

From what I see in the thread, he didn't get that far. People seem not to like the Apollo 030 that much. The increased memory size is quite sweet though. I'm pushing my proto anyways.

I agree with you on that. I like the extra ram too, but personally I prefer the 020 because it creates less heat so it should be more stable and it should be cheaper than 030.
Keep us posted!! :-D

I would definitely buy either version as long as it is compatible with the A600! Even the cheaper one would be ok.
