DECstation and DECsystem 2100

Specifications

• 12.5 MHz R2000 CPU with R2010 FPU
• Maximum of 24 MB RAM in 2 MB pairs (memory part number MS01-AA)
• 1024x864 framebuffer option module, either mono (with memory part number VFB01) or 8-bit color (with memory part number VFB02). Both provides 16x16 hardware sprite cursor (not supported)
• SII SCSI-I controller with obscure external connector (HONDA68 male; wide SCSI-3-like, but other gender)
• AMD LANCE 10 Mbit Ethernet interface with switchable AUI and BNC connectors
• DC7085 four-port serial chip (DZ-11 clone)
• Two MMJ-6 serial ports, with maximum speed of 9600 baud. One port has partial modem control, the other has none.
• DIN-7 connector for mouse and MMJ-5 connector for keyboard. (An adaption-connector can make these ports usable as RS-232 serial ports with no modem control.)
