ACA 1221 accelerator: Who's got one?

[amiga1260]

I bought one and I unlocked everything. I had some issue with resetting my Amiga 1200 with the ACA 1221. I solved the problem with using other Amiga 1200 with timing fix.

You can do some raytracing, Image processing, Word processing with this card.

You have to buy the the license codes for overclocking 28 MHz and 64 MB for the first two things, but will be slow. The best option to have more fun is  getting a Blizzard 1230 IV with FPU.

Maprom will help you to use other ROM. You could softkick 3.1 when you have 3.0.

It's impossible to know if your Amiga 1200 needs a timing fix. The only way to know if you need a timing fix, is buy the ACA 1221 and test it.

If the Amiga 1200 crashinig the whole time with the ACA 1221, then you need to the timing fix.

Here is the link about Timing fix and read about ACA 1230.

Years ago I bought a Blizzard 1230IV card, but in my A1200 crashes every time. I traveled 3 hours to the Amiga Store to swap for another card and that one still works to day with other A1200's in my collection.

@Bruno: you could look for a friend with solder skills or repair shop in the neighbourhood to do the timing fix.

On the website http://whdload.de/ you could search the game and read the readme of the game which will stated how much memory it needed.
