ACA 1231/42MHz + Battery CR-1220
Amiga 1200 Accelerator Card w/ 68030 CPU incl. MMU
The new ACA-1231/42 offers everything a retro gamer wants:
Although the ACA-1231/42 features less MHz than the Blizzard 1230-IV card (42 MHz** vs. 50 MHz), it actually achieves more MIPS (Million Instructions per Second). The reason for this efficiency is the high clock speed of the on-board memory (25 x 3.333 MHz).
¤ Memory Aplenty:
The ACA-1231/42 comes with 64 MB RAM, 1 MB of which are reserved to map the Kickstart into the fast memory. With Kickstart 3.1*** there are 63 MB FastMem available to applications when you switch the A1200 on (1 MB is always located at address 0x00C00000 to gain compatibility with old or badly programmed software).
¤ On Time:
The ACA-1231/42, unlike its predecessor ACA-1230, always comes with an RTC (Real Time Clock) chip installed. You only have to add a battery.
¤ Hardware Compatibility:
The ACA-1231/42 is more tolerant towards different revisions of the A1200 board then the ACA-1230 was.
¤ Software Compatibility:
The ACA-1231/42 sports a fully featured 68030 processor, which also includes a functional MMU (Memory Management Unit). The MMU can not only be used to map a Kickstart ROM image to FastMem, it's also crucial for WHDLoad. The ACA-1231/42 is 100% compatible with WHDLoad!
