I agree. A lot can be done to improve the lives of A1200 owners. However, even compared to a MiniMig project it's a strange proposal. Since making a case for A1200 is building something for a shrinking market. Building for Efika, Flex and even MiniMig is building for a growing market (Counting Efika and Flex as ITX market, and you are playing with the big'uns).
That said...
I'd love to see two products. One, a product that would reroute ITX I/O ports to a PCB strip that would fit inside the backplate of an A1200. This way owners with dead wedgies could house an ITX inside their box easily.
Two, a new wedgie. The precessor or followup to product no one. This wedgie would easily hold either a A500 or A1200 computer (some modularity to back plate? I can't be bothered to look up my A500 now).
And bundled with the I/O reroute module, with keyboard - in three parts you'd have an Amiga like wedgie computer that would host any ITX, FLEX ITX or PicoITX with ease. Perhaps some height problems, but you have some freedom...
Such a product would consist of three main parts:
1) The wedgie, also compatible with A500 and A1200
2) The IO rerouter. Two versions could exist. One for Amigas which convert PS2 to amiga signals. One for USB and PC standards (Efika and Flex etc)
3) The keyboard for the PC version. A USB keyboard that connect internally to a USB header on the IO rerouter.
It'll be expensive as h*ll. IO rerouter for Amiga would be more expensive than the case, and keyboard would only be compatible with this setup. But maybe some standard ones for medical equipment or similar products could be sourced.
Also the Amiga version of the IO router doesn't need to be made since an amiga keyboard can be used. But it could be made for those cases where a wedgie amiga keyboard doesn't exist for you anymore or in your locale.
