Hello all -
	Some may recognize me from the Alpha or Vax ports...
Anyway, I just recieved 2 SPARCStation 1+ boxes, a SPARCStation 2, and I'm
awaiting delivery on a SPARCStation LX. Aside from the info I've collected
from sunhelp.org (below) and on NetBSD's site, what else can you guys tell
me about these boxes?
	Thanks in advance...

        CPU:            501-1632
        Chassis type:   square pizza box
        Bus:            SBus @ 25MHz, 3 slots (slot 3 slave-only)
        Memory:         64M (40M?) physical with synchronous parity,
                        512M/process virtual; 64K write-through cache,
                        direct-mapped, virtually indexed, virtually
                        tagged, 16-byte lines; 50ns cycle
        Architecture:   sun4c
        Notes:          Code name "Campus B". 1M or 4M x 9 30-pin 100ns
                        SIMMs, in four banks. 1.44M 3.5" floppy.
                        Essentially same as SPARCstation 1, just faster
                        clock and improved SCSI controller. First
                        supported in SunOS 4.0.3c.
Audio --- AMD AM79C30A 
"Telephone quality" audio chip capable of 8 KHz monaural audio input and
output that supports mu-law and A-law but not linear encoding; found in
sun4c systems and SPARCclassic.

    SPARCstation 2 (4/75)
        Processor(s):   CY7C601 @ 40MHz, TI TMS390C601A (602A ?), Sun-4c
                        MMU, 16 hardware contexts, 28.5 MIPS, 4.2
                        MFLOPS, 21.8 SPECint92, 22.8 SPECfp92, 517
                        SPECintRate92, 541 SPECfpRate92
        CPU:            501-1638/1744/1858/1859/1912/1926/1989/1995
        Chassis type:   square pizza box
        Bus:            SBus @ 20MHz, 3 slots
        Memory:         64M physical on motherboard/128M total, 64K
                        write-through cache, direct-mapped, virtually
                        indexed, virtually tagged, 32-byte lines
        Architecture:   sun4c
        Notes:          Code name "Calvin". 4M x 9 30-pin 80ns SIMMs, in
                        four banks. Case slightly larger and has more
                        ventilation. (Some models apparently have LSI
                        L64811 @ 40MHz?) Expansion beyond 64M is
                        possible with a 32M card which can take a 32M
                        daughterboard (card blocks SBus slot). First
                        supported in SunOS 4.1.1.

    SPARCstation LX/ZX (4/30)
        Processor(s):   microSPARC @ 50MHz, 59.1 MIPS, 4.6 MFLOPS,
                        26.4 SPECint92, 21.0 SPECfp92,
                        626 SPECintRate92, 498 SPECfpRate92
        CPU:            501-2031/2032/2233/2474
        Chassis type:   lunchbox
        Bus:            SBus @ 20MHz, 2 slots
        Memory:         96M physical
        Architecture:   sun4m
        Notes:          Sun4m architecture, but no Mbus. Shares code
                        name "Sunergy" with SPARCclassic. Uniprocessor
                        only. Takes pairs of 4M or 16M 60ns SIMMs.
                        Soldered CPU chip. Onboard cgsix framebuffer, 1M
                        VRAM standard, expandable to 2M. DBRI 16-bit
                        audio/ISDN chip. First supported in SunOS
                        4.1.3c.
Audio --- T5900FC 
DBRI (Dual Basic-Rate ISDN) chip for audio I/O that, in addition to audio,
supports ISDN (dual B channels plus one D channel) but requires an NT1 in
the US to connect to a line; found in LX, 10, and 20. Those systems
require a CS4215 codec to generate and receive audio.
