We had seen an early A1000 project with an A3000-like redesign (GBA) several years back. The A500+ and A500, the A4000 in a few different source formats (Rev B, Rev D/CR, and a modified version for ATX) more recently, and the A1200 last year. We also had the A3640 cloned and merged with the 68060 adapter to make it an A3660.
The A500 family systems were plentiful, and a more simple/cheaper project, with the batteries on the 500+ took their toll on the otherwise prized 2MB ChipRAM ECS system.
The A4000D, particularly the Rev B, had both caps and battery killing them left and right, plus a few good hacks can be done to enhance them with more FastRAM in a few cases (spare chips were also in the wild).
The A1200 was another cap-killed PCB, but otherwise was a simple board for the SMD hot-air solderers to resurrect.
This year the A3000 and A2000, both heavily through-hole and larger/multi-component (more expensive electronics parts list) and/or multi-layer, finally got the effort from those that wanted to be able to save battery-damaged systems with new boards.
