The SGI IRIS 3000 series is the last range of Motorola 680x0 graphics terminals and workstations made by Silicon Graphics, sold from 1986 until the MIPS-based IRIS 4D series replaced it.[1][2] Every model has the 16 MHz 68020 IP2 processor board, IM1 memory on a private bus, an optional FP1 floating-point board and the GL2 graphics boards (GF2, UC4, DC4 and BP3) in a 20-slot Multibus card cage.[1][2] The same boards are used in the SGI IRIS 2000 Turbo models, and SGI's field-service course describes the 2400 Turbo as the same system as the IRIS 3020 apart from the cabinet, power supply, chassis and monitor.[4] Control Data sold the 3130 under its own name as the Cyber 910.[2][1]
History
[edit | edit source]The range was launched in February 1986 with three models: the 3010 terminal and the 3020 and 3030 workstations. The later 3110, 3115, 3120 and 3130 have faster Geometry Engines.[1] In November 1989 SGI classed the 3000 products as mature and announced the end of production, with support (subject to parts) for five more years.[1][2] SGI said it had sold more than 3500 IRIS 2000 and 3000 systems.[2]
Models
[edit | edit source]| Model | Type | Geometry Engines | Disk and controller |
|---|---|---|---|
| 3010 | Terminal | 10 at 8 MHz | ST-506 (DSD) |
| 3020 | Workstation | 10 at 8 MHz | ST-506 (DSD), 72 MB |
| 3030 | Workstation | 10 at 8 MHz | ESDI (Storager II), 170 MB |
| 3110 | Terminal | 12 at 10 MHz | ST-506 (DSD) |
| 3115 | Workstation | 12 at 10 MHz | ST-506 (DSD), 72 MB |
| 3120 | Workstation | 12 at 10 MHz | ST-506 (DSD), 72 MB; ESDI, 170 MB, on the 3120B |
| 3130 | Workstation | 12 at 10 MHz | ESDI (Storager II) |
The 3010 terminal has a floppy drive and a small local disk and runs a cut-down GL2 UNIX; it can also act as a host-attached terminal over RS-232 or Ethernet.[7][4] SGI describes the 3110 as a 3010 with Z-clipping and 10 MHz Geometry Engines, the 3115 as a workstation with a 72 MB disk and 4 MB of memory (expandable to 8 MB), the 3120 and 3120B as 3020s with the faster engines and a 72 MB or 170 MB disk, and the 3130 as a 3030 with the FP1 board, a cartridge tape drive, 32 bitplanes, 8 MB of memory, Z-clipping and the faster engines. The 2300 Turbo and 2400 Turbo are the equivalents of the 3010 and 3020.[6]
Sources disagree on three points. Jonathan Levine's 1993 IRIS FAQ lists the 3030 as a rack-mounted SMD system, while SGI's course and owner's guide give it a 170 MB ESDI disk on the Storager controller, as Stricklin does.[2][4][3][7] sgistuff.net lists the 3120 with an ESDI disk, while SGI's owner's guide gives the 3120 an ST-506 disk and the 3120B an ESDI disk.[1][3] sgistuff.net also lists the 3110 as a workstation, while SGI describes it as a 3010 terminal with faster engines, and Stricklin also counts it among the terminals.[1][6][7]
Hardware
[edit | edit source]Card cage
[edit | edit source]The Multibus backplane is split into a CPU side (slots 1 to 9) and a graphics side (slots 10 to 20); the P2 traces are cut between slots 9 and 10. The IM1 memory boards, the FP1, the IP2, the Ethernet board and the disk controller fill the CPU side from slot 1 upwards, and the BP3 bitplane boards, DC4, UC4 and GF2 occupy slots 10 to 20.[2] Some 3000 systems were shipped with a backplane that lacks connectors and card guides in unused slots, so that a second IM1 board cannot be added without more work.[1]
Processor and memory
[edit | edit source]The IP2 carries the 68020, four RS-232 serial ports, 256 KB of EPROM for start-up, configuration and diagnostics, and a real-time clock with non-volatile memory backed by a lithium battery, an Eagle-Picher Keeper II LTC-7P.[4][8][2] Memory is on IM1 boards of 2 or 4 MB connected to the IP2 by a ribbon-cable private bus; the RAM is soldered to the boards, so memory is added a board at a time, and the last board in the chain needs an IM1 terminator.[1]
Graphics and video
[edit | edit source]Each BP3 board holds four 1024 × 1024 bitplanes; two boards (eight bitplanes) are the minimum.[2] The standard output is 1024 × 768 at 60 Hz non-interlaced. SGI also offered 33 Hz interlaced 1024 × 768, 30 Hz 636 × 485 and 25 Hz 780 × 575 video, each machine being built with two modes chosen at the time of order by the DC4 board and the IP2 switch settings.[4][2] The standard monitor was a 19-inch 60 Hz non-interlaced tilt-and-swivel model; Levine knew of no monitors shipped by SGI other than Hitachi ones.[2]
Cabinet and power
[edit | edit source]The cabinet has a 720 W power supply in its own compartment with four outputs: +5 V, +12 V, −12 V and −5 V.[4][9] SGI's site table gives an operating range of 10 to 30 °C at 20 to 80% relative humidity, at least 3 in (7.6 cm) of clearance on all sides, and a cabinet consumption of 1250 VA (1000 W).[5] The owner's guide warns not to connect the IRIS to a switched power outlet.[10]
