For years I wanted to have a MicroVAX II that would be livingroom-friendly, i.e. quiet and nice to look at.
After about a month of construction, two power supplies, three custom PCBs and six quiet fans, the homebrew MicroVAX II is ready.
For my “Hombrew MicroVAX II” project, I have designed and built a custom side panel board, which includes
* A Direct replacement for the DELQA cab kit (70-22786-01) (dual – can connect to two DELQAs)
* Two DHV11 cab kits (similar to H3173-A, CK-DHV11-XX)
* Space for a FUNCT/SEL SLU Module
* Drivers for front panel external LEDs and switches

The terminal found is a model 12250, manufactured in October 1990.Continue reading “IIS Terminal”
