May 1982 Sun introduced the Sun-1 which was based on the Motorola 68000.
The Sun-1 was designed by Andy Bechtolsheim while he was a grad student at Stanford. It was funded by DARPA.
The Sun-1 had 256KB of memory on board This memory was called Chrislin Multibus memory (for you trivia buffs)
later available with 1MB of parity memory

2/160 was a 12 slot VME system.
November 1984 the 2/50 was introduced as the first below $10,000 workstation. It had no expansion and was used primarily diskless.
Also in November the 2/160 was introduced. It was a color system that could have up to 8MB of RAM.
June 1985 the 2/130 was introduced.
The 2/130 was a expandable VME based monochrome workstation. It had 12 slots, 71 to 760 MB of disk, 1/4" and 1/2" tape were available.
In September of 1985 the Sun-3 was introduced.
By March 1990 166,000 Sun-3 workstations, servers and board level products had been shipped to customers.
The Sun-3 was based on a Motorola 68020 processor.
3/75 was a monochrome system with up to 8MB RAM it supported the 71MB disks.
3/160C was a color workstation with up to 16MB RAM.
it was VME based and could use Multibus boards with an adapter
The 3/160 had 2MIPS
3/160M was a monochrome workstation with up to 16MB RAM. it was VME based and could use Multibus boards with an adapter
3/180S was a 76" rack mounted system that was used primarily as a fileserver. It was configured with one or two 71 or 130MB drives and up to four 380MB drives and 1/4" or 1/2" tape drive. The 3/180 had 2MIPS
In January 1986 Sun introduced which was the first below $5,000 the 3/50M.
3/50M used the 15MHz 68020 with a 19" monochrome display and 4MB RAM and no memory expansion. It was primarily used diskless but did have a SCSI port on the motherboard. An optional floating point chip was available. The 3/50 had 1.5MIPS
3/52M used the 15MHz 68020 with a 19" monochrome display and 4MB RAM and no memory expansion. It was configured with a 71MB disk drive and a 1/4" tape drive. An optional floating point chip was available. The 3/52 had 1.5MIPS
In March 1986 Sun introduced the 3/160G
3/160G used the 15MHz 68020 with a 19" high-resolution grayscale 1600x1280 monitor. An optional floating point chip was available.
In August 1986 Sun introduced the 3/140 and 3/260.
3/110 was the color 3 slot VME system. It had 2MIPS of performance. There was also a FPA board available for it to up the floating point performance. This was used as either desktop or deskside system.
3/260 was initially monochrome workstation with up to 16MB RAM.
it was VME based and could use Multibus boards
with an adapter
The 3/260 had 4MIPS
The 3/260 was the first 25MHz 68020 in the workstation market
3/280S was a 76" rack mounted system that was used primarily as a fileserver. It was configured with upto four 575MB drives and 1/4" or 1/2" tape drive. The 3/280 had 4 MIPS, 8MB min memory and max of 32MB ECC memory
In Jan of 1987 Sun introduced the 3/60
3/140 was the monochrome compliment to the 3/110. It had 2MIPS of performance. There was also a FPA board available for it to up the floating point performance.
In July of 1987 Sun introduced the 3/60
3/60 was a desktop system with 3MIPS performance The 3/60 was available in optional color or greyscale monitors. It could be expanded up to 24MB of RAM.
3/150 was a 6 slot VME system that was used primarily as a deskside system. The 3/150 used the CPU as the 3/160 & 180. It was a 2MIPS system. Max of 16 of RAM,4 on CPU & 3 4MB boards. It came about because of the HPW contract and was made into a real product.
3E was Sun's first 6u VME board product. The 3E had 2 or 4MB of memory on board. Up to 16MB total It used a 3MIP Motorola 68020 with a 68881 floating point processor. It was for people that were designing 6u VME systems that wanted to take advantage of Sun's developement environment and number of application software products.
In April of 1989 Sun introduced the 3/80, 3/470 & 3/480.
This would be the last of the Sun-3 line.
3/80 was a desktop system that looked exactly like a SPARCstation 1. It used a 20MHz Motorola 68030 and a 68882 floating point processor. It used the same frame buffers and peripherals as the 3/60 and 4/100 workstations.
3/470 was a 12 slot VME system that had a 7 MIP 68030 processor. It used between 8 and 128MB of ECC memory and up to 5.5GB of SMD mass storage.
3/480 was a 16 slot VME rack system that had a 7 MIP 68030 processor. It used between 8 and 128MB of ECC memory and up to 14GB of SMD mass storage. It could support up to 66 serial ports.
