It would be a good idea to include the possibility to add an ISP connector on your board. Rarely used, but makes life much easier if you need to reprogram the boot loader (or want to remove it entirely and use all the space for your application). Layout is like this (view from top): http://www.evilm...

I guess that the IBM engineers never thought that this plastic would survive connected to a computer 25+ years Presumably, 10 years MTBF was the goal defined by the IBM engineers. That's already pretty ambitious, but "planned obsolescence" wasn't so important back then. I'm sure that, as with some ...

I've got one here (rubber dome Model M, that is); you can. My one has 1-part key caps (so, stem and cap in one), but you can still simply take them off. There's a rubber dome instead of a spring below; that's the big difference.

The big (IMO) downside to this design is the power hungry original IBM controller board. Even with the very large battery, it won't last more than a day without reloading.
