Dolch PAC 65

Dolch network analyzers and related portable computers gained notoreity on Geekhack for the use of Cherry MX switches in the keyboards of some models. Personally, I didn’t care about the keyboard but found the computer more intriguing, so I picked this up. Eventual goals involve newer internals.
