-
- You have a 2nd-generation Sun Workstation, dating from late 1983. Welcome to
- 9+ year old hardware technology.
-
- It also contains a bus called the MultiBus (remember those?). There are
- several (9) Multibus slots available inside the machine; one of those is used
- for the CPU board, 1 (or more) slots is used for main memory, and the other
- slots are free for things like a Xylogics SMD disk controller, 3Com (or Sun)
- Ethernet Controller, Sun Color Video Board, Sun-2 (Mono) Video Board, SCSI
- board (which also contained 4 extra serial ports, in addition to the SCSI), a
- Ciprico Tapemaster 9-track 1/2" tape controller board, Sky Floating Point
- coprocessor board, and a couple of tape drive controller boards (Adaptec ACB
- 4000 and Sysgen SC-4000). A common high-end configuration would have been:
-
- Slot Contents
- ---- --------
- 1 Sun-2 CPU board
- 2 Sun-2 1 Mbyte Main Memory
- 3 Sun-2 1 Mbyte memory expansion card
- 4 Sun-2 Ethernet board (or 3Com)
- 5 Sun-2 SCSI Host Adapter
- 6 Sun-2 Video
- 7 Xylogics 450 SMD disk controller board
- 8 Sky Floating Point Processor board
- 9 Sun Color Video Controller
-
- The memory boards have to be adjacent to the CPU board in slot 1, and they
- can go in slots 2, 3, 4 and 5, yielding a maximum of 4 Mb.
-
- Your Sun-2/120 contains a Motorola MC68010 processor, running at 10 (?) MHz.
-
- This makes it slower than a snail. The latest operating system available
- from Sun that supports this system is SunOS 4.0.3, which is now 6 O/S
- releases behind the current O/S release available for the SPARC-based systems.
- Welcome to 3+ year old software technology. In addition, it is dreadfully
- slow, and unless you have gobs of memory, a better choice would be to attempt
- to find a copy of SunOS 3.5(.2), Sun's last 4.2BSD-based O/S (SunOS 4.0 and
- releases up to and including SunOS 4.1.3 started to base itself on 4.3BSD.).
- SunOS 3.5(.2) will run noticably faster on the Sun-2/120.
-
- About the only thing your Sun-2/120 system shares in common with modern Suns
- is (a) the screen resolution is still the same (1152x900), unbelievably; and
- (b) they BOTH USE THE SAME GOD-D*MNED !*&$@%$&^% SERIAL PORTS, utilizing
- Zilog Z8530 dual UART chips!
-
- In early 1985, I thought the Sun-2/120 on/under my desk was that cat's meow.
- It is now 8 years later, and the best use of a Sun-2/120 that I can think of
- is as a Floor Heater for people in cold climates with inadequate heating
- systems (-:
-
- Basically, any modern PC will run rings around your old, tired warhorse.
- Seriously, ditch it and get a 486DX2/66 or 486DX/50-based PC clone system and
- run 386BSD (4.3BSD++ based) on it instead. Send your Sun-2/120 to a museum ...
