[Coco] Mechanical keyboard upgrades for the CoCo

[Brian Blake]

Mark,

The Spectrum Projects and the Macrotron Professional were/are the same

I've got the HJL-57, MarkData SuperPro and the Macrotron Professional 
keyboard. If you want, I can send you pics of the mounting and support 
hardware for each.
