The PC2086 S/D/30 Personal Computer / PC12 MD / PC12 HRCD / PC14 CD / PC14 HRCD Service Manual is Amstrad's own service manual for the PC2086 and four monitors. 58 pages, with a text layer and searchable.
Contents
[edit | edit source]- PC2086 S/D/30 section — technical specification; safety tests; alignment instructions (page 3, with the DVM test points given); electrical parts list (page 4); mechanical exploded view and parts list (5–6); keyboard exploded view and parts list (6); main/LED PCB top and bottom views (7–8); power/switch PCB (9); then the chassis schematics, one per functional block — memory and disc controller (10), expansion bus (12), printer port controller (13), support controller (14), video (15), keyboard controller (16), keyboard (17) and power supply (18)
- PC12 MD/O section — alignment instructions (19); monitor/CRT/LED PCB (20); cabinet exploded view and parts list (23); electrical parts list (24)
- PC12 HRCD/O section — alignment instructions (25); electrical parts list (26); monitor and CRT/LED PCBs (27); chassis schematic (30); cabinet exploded view and parts list (31)
- PC14 HRCD/O section — chassis schematic (32); electrical parts list (33); alignment instructions (42); monitor and CRT/LED PCBs (43); chassis schematic (44); cabinet parts list (46)
- PC14 CD/O section — alignment instructions (34); monitor and CRT/LED PCBs (36); schematic (37); electrical parts list (40); cabinet parts list and exploded view (41)
- PC12 MD/D section — wiring diagram (48); power supply PCB component layout and monitor PCB layout (49); electrical parts list (50); schematic (51); cabinet parts list (52)
- PC12 HRCD/D section — cabinet parts list (54); wiring diagram (55); waveforms, monitor PCB layout and power supply layout (56); schematic (57); electrical parts list (58)
What it settles
[edit | edit source]- The PC2086's own power supply is documented, with a power supply chassis schematic diagram on page 18 and a power/switch PCB drawing on page 9 — so this is a machine whose supply can be repaired from the manual rather than replaced blind.
- The schematics are split by function, not by sheet number, which makes tracing a fault far quicker: memory and disc controller, expansion bus, printer port, support controller, video, keyboard controller and keyboard each have their own drawing.
- Six separate monitor sections, each with its own alignment instructions and its own electrical parts list — the /O and /D suffixes distinguish two builds of the same nominal monitor, and their parts lists are not interchangeable. Check which build is in front of you before ordering parts or comparing a drawing.
- Two of the monitor sections note that alignment instructions will be published as an amendment — so for the PC12 MD/D and PC12 HRCD/D those procedures are absent from this edition by Amstrad's own admission, not lost.
What this manual does not contain
[edit | edit source]- Alignment instructions for the PC12 MD/D and PC12 HRCD/D, as noted above.
- No floppy or hard disc drive service data.
- No fault-symptom table or diagnostic flowchart for the computer.
- No coverage of the PC2286, PC2386 or PC2640.
