ACA1220
ACA1220 is an accelerator for the A1200 computer.

Processor
ACA1220 cards are based on the Motorola 68020 processor (the PGA version). These processors are used and may show scratches and dents. All processors are completely tested prior to installation on an accelerator, and all processors are guaranteed to work at the speed that's printed on them. Individual Computers does not sell ACA1220 boards with overclocked processors. Different versions are available depending on CPU availability:
- 68020 clocked at 16,667MHz (ACA1220-16)
- 68020 clocked at 20MHz (ACA1220-20)
- 68020 clocked at 25MHz (ACA1220-25)
- 68020 clocked at 33MHz (ACA1220-33)
Memory
All ACA1220 cards come with 128MBytes fastmem pre-installed. For OS3.0 users, these cards have 1MByte autoconfiguring memory only. ACAtune will add 126MBytes of memory to the system manually on start-up. For Kickstart version 3.1 or higher, the memory is detected and added automatically by the OS. Please note that the special memory organization of the ACA1220 always reserves 1MByte for the Fastrom option. This resereved memory area cannot be used as normal fastmem. Since the Z2 memory area remains unused, the cards are 100% PCMCIA compatible.
available ACAtune options
ACA1220 only supports a very limited number of ACAtune options. Tuning options like Z2 options, fastchip and cacheing of areas that should not be cached under normal conditions have been removed for stability reasons. All access speeds have been optimized for the highest possible safe speeds.
manuals
ACA1220 and ACA1232 share the same board, and they are very similar (if not identical) in handling. They therefore share the same instruction sheet. Every card comes with one German and one English instruction sheet. You may also get a translation from your reseller in your local language.
ACA 12xx Benchmarks
Benchmarks are measured with AIBB and the popular Sysinfo tool. While AIBB gives detailed information about the performance in specialized cases, Sysinfo will only give you a rough estimation of the performance you can get. We recommend to download the AIBB modules and compare the specific test results against your machine - this will give you much more information about a certain strength or weakness of the card you're comparing. Fastmem performance is measured with the freely available tool "Bustest". Only the "read multiple" and "write multiple" values are given here. Results may vary due to cache alignment differencies. Starting with the ACA1234, Bustest version 0.19 was used - the previous version was obviously too generous for some tests; take older measurements with a grain of salt.
