IBM PS2 Hardware Interface Technical Reference (May 1988)
The IBM Personal System/2 Hardware Interface Technical Reference is IBM's 625-page family-wide interface reference for the Micro Channel PS/2 models, First Edition, May 1988. The preface describes it as the manual for functions and architecture common to several PS/2 models, to be used with the model-specific technical references and the PS/2 and PC BIOS Interface Technical Reference. In it, Type 1 means the initial hardware design level of a function, and Type 2, Type 3 and so on the later levels (preface, p. ii).

What this manual does not contain
It is a programming and interface reference, not a service manual: no FRUs, removal procedures, symptom index, schematics or component values. BIOS is in the separate BIOS Interface Technical Reference. It predates XGA, so video is the VGA only. By October 1990 IBM had divided this material into the Architectures and Common Interfaces volumes.
What it settles
The power supply sections define three DC outputs, +5, +12 and −12 V, for the Micro Channel supplies of Types 1, 2 and 3. A short on any output, or an internal overvoltage before any output exceeds 130 % of nominal, latches all outputs off; the supply restarts only after the fault is removed and the power switch has been off for at least ten seconds (PDF pp. 579 and 587). The Type 1 supply plugs into the system board through a 50-pin card-edge connector, the Type 2 through a 15-pin connector with two 4-pin fixed disk connectors, and the Type 3 through a 12-pin connector (J7) and a 6-pin connector (J14) (PDF pp. 580-581 and 588).
