The Macintosh IIvi is a desktop Macintosh introduced by Apple on 19 October 1992 and discontinued on 10 February 1993.[1] It is the low-cost version of the Macintosh IIvx: the same case and logic board design, with the 68030 at 16 MHz instead of 32 MHz, no cache and no FPU, though the board has a socket for one.[2] Apple offered it in Europe and the Pacific and not in the United States, where the Performa 600 was sold instead.[3][1] Apple's service manual covers it with the IIvx and Performa 600.[4]
Specifications
[edit | edit source]| Item | Specification |
|---|---|
| Processor | Motorola 68030 at 15.6672 MHz with built-in MMU; ROM and RAM reads take four clocks (one wait state)[2] |
| FPU | None fitted; socket for a 68882, which runs at the processor's speed[2] |
| Cache | None[2] |
| RAM | 4 MB soldered; four 30-pin SIMM sockets, all four filled with identical 80 ns SIMMs of 256K to 16 MB; 68 MB maximum[2] |
| ROM | 1 MB[4] |
| VRAM | 512K or 1 MB on two VRAM SIMMs, 100 ns, fitted in identical pairs[2] |
| Video modes | 512K: 512 × 384 at up to 16 bits per pixel, 640 × 480 at up to 8. 1 MB: 640 × 480 at up to 16[4] |
| Expansion | Three NuBus slots (13.9 W each, 41.7 W total); one 120-pin accelerator slot (5 W)[2] |
| Serial | Two RS-232/RS-422 ports, 230.4 kbaud maximum, 0.92 Mbit/s with an external clock[4] |
| Power supply | 85-270 V AC, automatic; 112 W maximum, 130 W peak; switched monitor outlet, 3 A[2] |
| Environment | Operating 10-40 °C; storage -40 to 47 °C; 5-95 % relative humidity; 0-3,048 m[4] |
| Case | Painted sheet metal with plastic front and back bezels; 325 × 412 × 150 mm (13 × 16.5 × 6 in)[2] |
The Service Source prints the A/C line input as 100-120 V AC at 200 W; the developer note gives 85-270 V AC, selected automatically.[4][2] Low End Mac's 230 W for the supply is not Apple's figure, which is 112 W.[5][2]
Hardware
[edit | edit source]Logic board
[edit | edit source]Apple's logic board part is 661-0760 for the IIvi (661-0759 IIvx, 661-0761 Performa 600).[4] On the IIvi board Recap-a-Mac photographed (820-0373-A), the cache SRAM positions and the FPU socket are empty.[6] The VASP chip combines video, memory mapping, sound and glue logic, and a 68HC05 microcontroller runs ADB, the clock, parameter RAM and soft power.[2] Software must use the Gestalt Manager to find out whether a IIvi has an FPU.[2]
Because RAM is tested and sized before video starts, the screen stays blank for a while at start-up, longer with more RAM fitted.[2]
Accelerator slot
[edit | edit source]The 120-pin slot takes accelerator cards. Apple warns that it is not compatible with processor-direct cards for other Macintosh models and that fitting one may damage the card and the computer; cards must stay within 5 W.[2] Low End Mac notes that the IIvi cannot take a cache card, but can take an accelerator.[5]
SCSI and CD-ROM
[edit | edit source]An active terminator on the logic board terminates the internal bus when no external device is attached. The 3.5-inch hard drive must be terminated; a device in the 5.25-inch bay must not be. Apple's internal CD-ROM uses SCSI ID 3.[2]
Power supply
[edit | edit source]Apple part 661-0758, shared with the IIvx and Centris 650; Apple Rescue of Denver lists it as Apple 614-0009, 112 W, made by Delta (SMP-120EB) or Astec (AA16870).[4][7] Its ratings from Apple's developer note are on Macintosh IIvi General Maintenance. Apple publishes no rail tolerances and no adjustment.[4]
Battery
[edit | edit source]A lithium backup battery keeps the clock and PRAM when the machine is unplugged.[2] Apple's test: measure on the 10 V DC range and replace the battery below 2.8 V.[4] Recap-a-Mac's IIvi board photograph shows heavy corrosion around the battery holder.[6]
Capacitors
[edit | edit source]Logic board 820-0373-A has six 47 µF 16 V surface-mount electrolytics and two 220 µF 16 V axials.[6] See Macintosh IIvi Capacitor Replacement Guide.
