The Hacker space museum should be hacked, though it's important to keep the historical value of (at least some of) the objects.
Tiny PC
Please leave the PC working with the password the same as when you found it. Some Ideas
* log into the PC, play with an old version of Linux * find some commands with bugs. The old versions often break if there are too many files * Install Linux 1.0. This should (hasn't yet been verified) work
Dalekopis
The Dalekopis should be able to run with a telnet service which can print from it.
* set up the service (documented in this wiki) * measure the messaging with the logic analyser
Bigger projects
* repair typewriters - talk to the owners first * set up a KVM - get the MAC and the NEC PC connected
