For Model 12 software checkout
Regarding the size of the M12, it’s ironic that if you look inside it's a lot of empty space for what it does. It’s meant to be upgradeable to Model 16B specs with an optional card cage and MC68000 hardware.
The keyboards do come up for sale on eBay regularly, but they are uncommon. It will run you between $100-$150 depending on condition. The 12/16B/6000 keyboards are interchangeable. You can also use a Model II/16 keyboard by fashioning a gender and pin-swap adapter.
