Microprocessor

The U80701 was developed by reverse engineering the MicroVAX 78032 microprocessor of the Digital Equipment Corporation (DEC). It was used in the Robotron K 1820 minicomputer - a clone of the DEC MicroVAX II.

The U80700 system includes the following chips:

  • U80701: CPU (DC333)
  • U80703: FPU (DC337)
  • U80707: Console interface/controller DLART (DC319)
  • U80709: CPU interface gate array (DC379)
  • U80711: Q22-Bus interface gate array (DC380)
gollark: Wow, this sounds like an excellent idea with no possible problems.
gollark: What? They should only do things if someone is actually *using* them, surely.
gollark: I mean, it may be entirely wrong.
gollark: Politics apparently draws on human instincts from when we lived in small tribes where political-ish goings-on could actually directly affect your life a lot, and where you had significant influence on them.
gollark: The only signals I know are factorio ones and I don't know them that well.
