IBM PS2 Model 55SX HITR Supplement
The IBM PS/2 Model 55 Supplement for the Hardware Interface and BIOS Interface Technical References is an IBM update package dated 7 February 1989, part number 01F0242, form number S01F-0242-00. The hosted scan is 72 pages and image-only. IBM issued new PS/2 models as supplements to be filed into the technical reference binders; this one is for the Model 55 SX (8555).

- insert a "Power Supply (Type 3)" tab into the Hardware Interface Technical Reference behind the "Power Supply (Types 1 and 2)" section, with the new Type 3 pages behind it;
- insert a "Model 55" tab at the back of the same binder, with the IBM Personal System/2 Model 55 Technical Reference pages behind it;
- file the "IBM Personal System/2 Model 55 Supplement" page behind the Supplements tab of the PS/2 and PC BIOS Interface Technical Reference.
