SUN SPARCstation 20


Dati generali sulla macchina

  SPARCstation 20M
      Processor(s):   SuperSPARC @ 50MHz, 86.1 MIPS
      Bus:            SBus, MBus
      Memory:         512M physical, 32K off-chip cache
      Notes:          32M standard. 1.44M 3.5" floppy.
  SPARCstation 20/xx
      Processor(s):   Mbus modules
      Bus:            SBus and Mbus; SBus for models 50 and 61 (and
                      possibly others?) @ 25MHz/64bits
      Memory:         512M physical
      Architecture:   sun4m
      Notes:          1.44M 3.5" floppy. 32M standard all models. Code
                      name "Kodiak". Uses SCA connectors (see Misc Q&A
                      #29) for internal SCSI drives. 16, 32, or 64M
                      60ns SIMMs. Some models (514, others?) use
                      double-width CPU modules that block SBus slots.

1. 99% 13w3 adapter will work. Or you just make urself: http://www.hut.fi/Misc/Electronics/faq/vga2rgb/interfacing.html#vga_13w3 2. use m64config -prconf to get current settings, m64config -res 800x600x60 format to set yours then reboot. Or fbconfig. 3. if sth wrong, you can use OBP command at ok prompt: printenv output-device see settings setenv output-device screen:r1024x768x70 then reset-all or reset
