Thanks to Amigakit for shipping my ACA1221ec the same day I ordered it. Their despatching seems to be really quick nowadays and I recieved this and other recent orders the next working day after ordering. So bigup to Matthew and crew.

Onto the board. I got it to go in my spare A1200 machine. In my other machine is a Blizzard 1220/4 so the ACA is like a modern day equivalant of this board.

Decided to leave it at the 28MHz default and maprom enabled.

Sysinfo reports 4925 Dhrystones / 5.14MIPs for this card vs the Bizzard's 4842 Dhrystones / 5.05 MIPS.

People have reported the ACA1221ec gets warm. It does but not 040 warm, about 030 50MHz warm, I couldn't burn my finger on it (this is @ 28MHz). The Biizzard does run its chip cooler - not sure if its because of the package type (PLCC vs PGA) or if its because if the speed of the memory.

Pics online show a full 68020 @ 16MHz rated but my board has an "EC" 020 but rated at 25MHz despite this, in the default setup for 9MB FAST RAM, the PCMCIA port is still usable. If I was to find the ADD4 board for my Blizzard 1220, it would render the PCMCIA port unusable so on the Blizzard I am restricted to 4MB.

On the Blizzard I have a 40MHz 68882 with 40Mhz crystal installed. There is no FPU socket on the ACA. The Blizzard has a RTC as standard - the ACA it is an optional board - £17 at time of writing.

Moving around on A-Train Hi Res mode does seem to be much more quicker on the ACA, as is Workbench operations in general. Everything seems so much more instant. I put this down to the MAPROM feature and the speed of the Fast Mem. Using Sysinfo v4.0, HDD access is slightly quicker on the ACA - PCMCIA CF read speed is about the same.

Both these cards are super stable, super compatible and cost about the same - the advantage of the ACA of course is there will be a warranty - the Blizzards were made in the mid 90s!

I would say if you need an FPU the Blizzard is the one to go for, other than that go for the ACA1221ec - its just over 100 pounds, you will have 9MB extra RAM (plus there is some ramdisk additional memory I believe you can activate- haven't tried the ultils yet), and you will be supporting new classic hardware and the resellers such as, but not exclusive to, Amigakit.

EDIT: Seems MAPROM isn't available yet. This will be a firmware update from what I understand so more performance is achievable it seems.

I ordered and RF lead on Thursday and even though it was after 6pm it still got picked and packed that evening ready to be sent the next day. Should have it on Monday so I can start testing my old A500+ and a load of old games and other software.
