You can drill out the rivet very easily. 7805s never go wrong unless heat
damaged, and that doesn't happen until long after the solder melts and the
PCB catches fire ;)

The SQB with QIMI mouse and 7805 was version 2, I seem to recall. On
version 3, we went to a switching supply, which we positioned behind the
floppy interface outside the case.

That was why we changed the design to have a

I'll check when I get home, but I think that it's yellow.

There is that. Our future designs will either use a high efficiency, low
heat device or they will have an ultra-high-efficiency buck regulator on
them (96% efficient) in cases where the device is more complex and
justifies the small extra cost.
We're learned a lot, and there's much better voltage
Great !!

incompatible ;)

Steve,
if the heat is a problem on your setup, there are drop-in replacement switching
mode regulators for the 7805 that can significantly reduce the oamount of heat
dissipation. I used to have a super-Q-board that became so hot I ran into
problems in summer - dropped in such a regulator and th

Great Marcel.
This will make it easy to introduce the QL to new people.
Congratulations on the new arrival.
