Here's another two to add to the list;
Comspec Arm 1000 (Amiga Rom Module for A1000)
Comspec SA500 (A500 SCSI Expansion Adapter)
The ARM 1000 allows you to add a Kickstart 1.3 ROM to the A1000.
I played with the prototype but it was never released to the public due to limited interest and required Hardware modifications.
The PAL Ground Modification was required and the PAL Chips at U6J and U6L on the Daughterboard needed to be replaced. Also some PaL jumpers were required
between Pin 1 of U6J to Pin 19 of U6K and Pin 15 of U6L.
I still have a copy of the manual.
Also unlike other Comspec Expansions for the A1000 the case was plastic and not metal like the AX1000 and SA1000
