Sun-2 Models
------------
2/120
Processor(s): 68010 @ 10MHz
CPU: 501-1007/1051
Chassis type: deskside
Bus: Multibus (9 slots)
Memory: 7M physical
Notes: First machines in deskside chassis. Serial
microswitch keyboard (type 2), Mouse Systems
optical mouse (Sun-2).
2/100U
Processor(s): 68010 @ 10MHz
CPU: 501-1007
Bus: Multibus
Notes: Upgraded Sun 100. Replaced CPU and memory boards
with first-generation Sun-2 CPU and memory
boards so original customers could run SunOS
1.x. Still has parallel kb/mouse interface so
type 1 keyboards and Sun-1 mice could be
connected.
2/150U
Notes: Apparently also an upgraded Sun-1.
2/170
Chassis type: rackmount
Bus: Multibus (15 slots)
Notes: Rackmount version of 2/120, with more slots.
2/50
Processor(s): 68010 @ 10MHz
CPU: 501-1141/1142/1143/1426/1427/1428
Chassis type: wide pizza box
Bus: VME (2 slots)
Memory: 7M physical
Notes: The (type 2) keyboard and mouse attach via an
adapter that accepts two modular plugs and
attaches to a DB15 port; later on, units were
apparently shipped with type 3 keyboards. The
CPU boards have a double-width back panel but
are otherwise identical to those in the 2/130
and 2/160.
2/130
2/160
Processor(s): 68010 @ 10MHz
CPU: 501-1144/1145/1146/1429/1430/1431
Chassis type: deskside
Bus: VME (12 slots)
Memory: 7M physical
Notes: First machine in 12-slot deskside VME chassis.
Has four-fan cooling tray instead of six as in
later machines, which led to cooling problems
with lots of cards. Backplane has only four P2
memory connectors bussed instead of six as in
later 12-slot backplanes; SCSI passthrough is in
slot 6 instead of 7 as in later 12-slot
backplanes. Upgradeable to a 3/160 by replacing
the CPU board. No information on the differences
between the 2/130 and the 2/160.
