Verify against Apple's Macintosh IIvx/IIvi/Performa 600 Service Source (hosted): DELETED 'Input Voltage 100V-240V AC' - that is the rating of the switched MONITOR OUTLET on the back; Apple prints the machine's own A/C line input as 100-120 VAC, a domestic-only figure, so a 220-240 V machine is a different supply and its primary-side parts are not interchangeable; DELETED '230 W maximum' (that is the Macintosh IIfx figure) and gave Apple's three real numbers - 200 W AC input, 3 A max at the ou... |

=== Logic board === | |||
The VASP chip combines video, memory mapping, sound, clock generation and glue logic, and is similar to the V8 of the [[Macintosh LC]].

{| class="wikitable styled-table" style="width: | |||
=== Accelerator slot === | |||
The 120-pin slot is for accelerator cards, much like the IIci cache slot. Apple warns that it is not compatible with processor-direct cards for other Macintosh models; the connector is the same but the signals differ, and fitting one may damage the card and the computer. Cards must stay within 5 W.<ref name="dn" /> A IIvx could be upgraded to a Centris 650 by exchanging the logic board, and Apple's Service Source refers the Power Macintosh 7100 upgrade to the 7100 manual.<ref name="ss" /> | |||
=== SCSI and CD-ROM === | |||
An active terminator on the logic board terminates the internal bus when no external device is attached, and switches off when a terminated external device is connected. 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, and its audio goes to a four-pin connector on the logic board.<ref name="dn" /> Apple's parts list shows AppleCD 300, 300i and 600i drives.<ref name="ss" /> | |||
=== Power supply === | |||
Apple part 661-0758, the same as the Centris 650's.<ref name="ss" /> Apple Rescue of Denver lists it as Apple 614-0009, 112 W, made by Delta (SMP-120EB) or Astec (AA16870).<ref name="arod" /> Its 80 mm fan cools the whole machine.<ref name="dn" /> | |||

The Macintosh IIvx is a desktop Macintosh introduced by Apple on 19 October 1992 and discontinued on 21 October 1993.[1] It is the faster version of the Performa 600: the same case and basic logic board, with a 68882 FPU and a 32K cache soldered to the board. Macworld measured it 25 to 35 per cent faster than the Performa 600.[2] With the Performa 600 it was the first Macintosh in a metal case and the first with a built-in CD-ROM drive; the case and power supply were used again for the Centris 650, Quadra 650 and Power Macintosh 7100.[3][4] Apple's service manual and developer note cover it with the Macintosh IIvi and Performa 600.[5][6]
History
[edit | edit source]Macworld reported in April 1993 that the IIvx belonged to Apple's new Centris mid-range line, but that Apple's lawyers had not finished the trademark check on the Centris name before it was released; Apple said it would not rename it.[7] The 68040 Macintosh Centris 650 arrived in the same case in February 1993, and Apple cut the IIvx's base price from US$2,949 to US$1,899.[4] Low End Mac found the IIvx slower than the Macintosh IIci, because its 32 MHz processor runs on a 16 MHz bus.[4]

The Service Source prints the machine's A/C line input as 100-120 V AC at 200 W, and the monitor outlet as 100-240 V AC, 3 A.[5] The developer note gives the supply's input as 85-270 V AC, selected automatically.[6] Low End Mac lists the supply as 230 W; Apple's figure is 112 W, and Macworld's review gives the same.[4][6][2]

Hardware
[edit | edit source]Logic board
[edit | edit source]The VASP chip combines video, memory mapping, sound, clock generation and glue logic, and is similar to the V8 of the Macintosh LC. A 68HC05 microcontroller, as in the Macintosh IIsi, runs ADB, the clock, parameter RAM and soft power.[6] Apple's logic board part is 661-0759 for the IIvx (661-0760 IIvi, 661-0761 Performa 600).[5]
Because RAM is tested and sized before video starts, the screen stays blank for a while at start-up, longer with more RAM fitted.[6] The IIvx does not support 1-bit mode on Apple's 12-inch RGB monitor.[6]
Accelerator slot
[edit | edit source]The 120-pin slot is for accelerator cards, much like the IIci cache slot. Apple warns that it is not compatible with processor-direct cards for other Macintosh models; the connector is the same but the signals differ, and fitting one may damage the card and the computer. Cards must stay within 5 W.[6] A IIvx could be upgraded to a Centris 650 by exchanging the logic board, and Apple's Service Source refers the Power Macintosh 7100 upgrade to the 7100 manual.[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, and switches off when a terminated external device is connected. 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, and its audio goes to a four-pin connector on the logic board.[6] Apple's parts list shows AppleCD 300, 300i and 600i drives.[5]
Power supply
[edit | edit source]Apple part 661-0758, the same as the Centris 650's.[5] Apple Rescue of Denver lists it as Apple 614-0009, 112 W, made by Delta (SMP-120EB) or Astec (AA16870).[3] Its 80 mm fan cools the whole machine.[6]
| Load | +5 V | +5 V trickle | +12 V | -12 V | Total |
|---|---|---|---|---|---|
| Minimum | 1.5 A | 0 A | 200 mA | 0 A | 9.9 W |
| Maximum | 15 A | 1 mA | 2.5 A | 600 mA | 112 W |
| Peak | 15 A | 1 mA | 6 A (12 s maximum) | 600 mA | 130 W |
The trickle output is live whenever the machine is plugged in and runs the clock, parameter RAM and the ADB power-on circuit; the +12 V peak rating covers every internal drive spinning up at once.[6] Apple publishes no rail tolerances and no adjustment.[5]
Battery
[edit | edit source]A 3.6 V lithium cell keeps the clock and PRAM when the machine is unplugged.[1][6] Apple's test: measure on the 10 V DC range, positive probe on the end marked "+" on the logic board, and replace the battery below 2.8 V.[5] See Macintosh IIvx General Maintenance.
Capacitors
[edit | edit source]The IIvi board Recap-a-Mac documents has six 47 µF 16 V surface-mount electrolytics and two 220 µF 16 V axials, and Console5 sells one logic board kit for the IIvx, IIvi and Performa 600. See Macintosh IIvx Capacitor Replacement Guide.[8]
