Accelerator Board ACA-620

68EC020 CPU and 9+1 MB RAM for Amiga 600

As a replacement for the extremely popular (and extremely sold out) ACA-630 accelerator card:

The new ACA-620 is powered by a 68EC020 CPU clocked at 16.67 MHz, and it provides the popular MapROM function, just like all other ACA cards do: MapROM allows executing a Kickstart ROM from fast 32-bit memory, increasing execution speed considerably. The ACA-620 provides 9+1 MBytes of RAM (1 MByte reserved for MapROM function).

Features:

• CPU MC68EC020 clocked at 16.67 MHz
• 9+1 MB RAM on-board

EUR 99.90 incl. 19% German VAT (EUR 83.95 excl. VAT for non-EU customers)

Awesome

Compact too! I like that the 600 has been getting attention lately. Can't wait to get mine back from dude man speaking of which.

Good option for this classic machines and with good price.

I need to get hold of an A600 again. :|

Re: ACA-620 incl. CPU 68EC020 and 9+1 MB RAM
 

Meh, I find these slow EC020 cards rather disappointing.

Re: ACA-620 incl. CPU 68EC020 and 9+1 MB RAM
 

I thought they were quite fast. Are they more slow than what is in a stock Amiga 1200?

Re: ACA-620 incl. CPU 68EC020 and 9+1 MB RAM
 

No, there's fast ram present, so it probably faster than stock A1200, but adding fast ram to a stock A1200 is also very cheap. I'd love to replace my aging 030+882@33MHz/32MB Apollo A630, but none of the ACA cards can do that.

Re: ACA-620 incl. CPU 68EC020 and 9+1 MB RAM
 

Yep, definitely a huge downgrade compared to the previous ACA630. Glad I got one before they sold out.

This seems like a nice little upgrade I guess. Better than nothing.

Re: ACA-620 incl. CPU 68EC020 and 9+1 MB RAM
 

It seems ACAtune allows enabling up to 12.3MB of ram, 1MB for kickstart and the rest could be used by special software (my proposals: p96 driver with indivisionECS??? disk buffers???):

It looks more or less easy to overclock to 25Mhz but it would require additional cooling. It's a pity it's not the 680ec020 25Mhz model but it's ok.
