+
+ 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.
