So I have been using the A1208 in my A1200s and it works fine. I think I have the V2 that I listed in the title. I bought it this summer from amigastore. Here the other day I wanted to try it in my ACA-500 (the original ACA-500). Seems like the ACA-500 did not detect it at all. I am using the latest firmware for the ACA-500. On Amigastore's website this memory expansion mentions it should work on A1200, ACA-500 or ACA-500 Plus.
This same ACA-500 works just fine with my fully unlocked ACA-1221. What could be the cause? Do we need another firmware update for the ACA-500 for it to work with this memory card?
