Personal Collection

I recently bought a H89 on ebay which contained the D-G Super 89 CPU board (along with an Cleveland Codonics Imaginator). The system was in poor condition and needs major cleaning and repair. I plan to have pictures and more details shortly.

I would love to get copies of both the DG CP/M Plus and DG MP/M II operating systems.
