Hi
Looking to buy one of these, but have noticed that they have been sold out for some time. Will there be a new batch soon or is something new coming to replace it?

The ACA1221ec has been replaced by the ACA1221lc quite some time ago (2019 if I remember right). This latest card of the series is also the fastest "per MHz" that I've made. In numbers: The new card gives you 16% more CPU performance at 6.4% lower clock rate.
Further, it's the first 68020 card that can sync the CPU to the main board, giving you 100% compatibility with a stock A1200. Finally the same CPU (68ec020, which has restrictions in the amount of memory that it can address) gives you more available memory than the ACA1221ec. On top of that, the IDE speeder can give you up to 4.5MB/sec CF card read speed, or even 7MB/sec if you have a fast physical harddrive.
In other words: The ACA1221lc does everything a little better than the ACA1221ec, so there is no need for the old design any more.
I use an Amiga 500 with ACA500PLUS+, so the things the LC can do extra is not really useful, if I read it correctly?
The one outstanding feature is it's higher speed at lower clock rate. I'd rate that key feature very usefuil for the ACA500plus as well
I have the ACA1221lc connected with the ACA500Plus. Running it at 46,50 MHz without problems (a good PSU is recommended).
There are some problems with memory if you use KS 3.1.4. With KS 3.0 or 3.1 your A500 will be flying.
Note that the MHz display in Sysinfo is way off. It just does not know that a 68020 can be that fast - memory at this speed was not around when Sysinfo was written.
The MHz display of AIBB is closer to reality.
This is the MemTest from AIBB, CPU Clock at 40 MHz
The last reply was more than 365 days ago, this thread is most likely obsolete. It is recommended to create a new thread instead.
