02:09 (cur | prev) +5,209 Josh talk contribs (Index the full PET 2001 drawing set sheet by sheet - 24 document pages that were reachable from no article. Notes what each sheet settles and that the 'Rev 2'/'Rev 3' titles are wiki numbering, not Commodore's) | ||||

|
01:29 (cur | prev) +1,192 Josh talk contribs (Link the two PET documents this drive documented: Commodore drawing 320130 sheet 1 and the third-party PET-Shack bundle, with what each does and does not contain (P4 orphan fix)) | ||||
| 02:08 | Commodore PET 2001 Capacitor Replacement Guide diffhist +1,382 Josh talk contribs (C22/C27 resolved: Commodore's own Display PCB Assembly placement drawing marks both 3.3 uF 200 V or 160 V, agreeing with the schematic against the parts list's '33 uF'. Adds the TIP-55A substitution procedure, the spark gaps and the flyback marking) | ||||
| 01:34 | File:PET-Shack PET 2001 Bundle.pdf diffhist +1,632 Josh talk contribs (P4 documentation drive: replace 'File uploaded with MsUpload' with a real summary of what the document is, what it establishes, its text-layer state and file size, an honest licence block and an honest statement that the original provenance was not recorded) | ||||

| 20:05 | Commodore PET 2001 General Maintenance diffhist +5,224 Josh talk contribs (Correct the generic PSU section: no 7805 and no regulator of any kind on the main logic board, no documented -5 V rail, cassette motor drivers run from +9 V unregulated not +12 V; remove the unsupported RIFA X2 instruction and the unsourced 6.3 VAC filament figure; cite everything to Commodore's four hosted documents; fix the non-existent Category:Commodore Maintenance Guides) | ||||
| 20:05 | Commodore PET 2001 diffhist +2,809 Josh talk contribs (Cite to Commodore's own PET 2001 parts lists and schematics; state the four static board assemblies, 6502 at UF3 with Vcc on pin 8, 8 MHz Y1, no regulator on the main logic board, cassette drivers on +9 V unregulated not +12 V; remove the piezo-speaker claim that contradicted the infobox; correct which models have the internal cassette deck; remove red links) | ||||

| 18:24 | Commodore PET 2001 Capacitor Replacement Guide diffhist +6,518 Josh talk contribs (Rebuild from Commodore's own PET 2001 parts lists: every electrolytic value on the page was wrong. Main logic board has only C7-C10 47uF 16V, not 4700uF/2200uF/1000uF/220uF/10uF; the 4700uF 25V is C1 on the display assembly; C101-C123 do not exist; no 7805 on the PET; board list corrected to 320008/320081/320132/320137; CRT and mains hazards stated properly; Unverified data cleared) | ||||
| N 18:24 | Commodore PET 2001 Service Documentation diffhist +5,324 Josh talk contribs (Create: index of Commodore's four PET 2001 service documents now hosted here (two parts lists, two schematics), with the four static-board assemblies from Commodore's own schematic note) | ||||
