- decstation.cpp: MIPS-based DECstation family
-
- WANTED: boot ROM dumps for KN02CA/KN04CA (MAXine) systems.
-
- NOTE: after all the spew of failing tests, press 'q' at the MORE prompt and
- wait a few seconds for the PROM monitor to appear.
- Type 'ls' for a list of commands (this is a very UNIX-flavored PROM monitor).
-
- Machine types:
- DECstation 3100 (PMAX/KN01):
- 16.67 MHz R2000 with FPU and MMU
- 24 MiB max RAM
- Serial: DEC "DZ" quad-UART (DC7085 gate array)
- SCSI: DEC "SII" SCSI interface (DC7061 gate array)
- Ethernet: AMD7990 "LANCE" controller
- Monochrome or color video on-board
- PMIN/KN01:
- Cheaper PMAX, 12.5 MHz R2000, othersame as PMAX
-
- Personal DECstation 5000/xx (MAXine/KN02CA for R3000, KN04CA? for R4000)
- 20, 25, or 33 MHz R3000 or 100 MHz R4000
- 40 MiB max RAM
- Serial: DEC "DZ" quad-UART for keyboard/mouse, SCC8530 for modem/printer
- SCSI: NCR53C94
- Ethernet: AMD7990 "LANCE" controller
- Audio/ISDN: AMD AM79C30
- Color 1024x768 8bpp video on-board
- 2 TURBOchannel slots
-
- DECstation 5000/1xx: (3MIN/KN02BA, KN04BA? for R4000):
- 20, 25, or 33 MHz R3000 or 100 MHz R4000
- 128 MiB max RAM
- Serial: 2x SCC8530
- SCSI: NCR53C94
- Ethernet: AMD7990 "LANCE" controller
- No on-board video
- 3 TURBOchannel slots
-
- DECstation 5000/200: (3MAX/KN02):
- 25 MHz R3000
- 480 MiB max RAM
- Serial: DEC "DZ" quad-UART
- SCSI: NCR53C94
- Ethernet: AMD7990 "LANCE" controllor
-
- DECstation 5000/240 (3MAX+/KN03AA), 5000/260 (3MAX+/KN05)
- 40 MHz R3400, or 120 MHz R4400.
- 480 MiB max RAM
- Serial: 2x SCC8530
- SCSI: NCR53C94
- Ethernet: AMD7990 "LANCE" controller
