20:13 (cur | prev) +2,363 Josh talk contribs (Cite to Sinclair's ZX Spectrum Service Manual and Issue 3 circuit diagram; ROM is 16 KB (page said '16 KB or 48 KB'), ULA Vcc is pin 14 and pin 40 is ground, RESET is edge contact 20A, there is no composite output and no 7812, 15 distinct colours not '15 plus black'; remove the invented Issue 1/2 errata table, the broken 50-way pinout table and the wrong ROM keyword map) | ||||
| 20:22 | Sinclair QL Service Manual diffhist +3,892 Josh talk contribs (Cite the manual itself; add the publisher (Thorn EMI Datatech for Sinclair Research), the manual history sheet showing this is Issue 3 of October 1985, the real sub-section breakdown of Sections 1-4, the Table 5.1-5.5 assembly names, the full figure list including 4.3, D9 and the two PCB layouts, and the missing templatestyles) | ||||
| 20:13 | Sinclair ZX81 diffhist +2,453 Josh talk contribs (Cite to Sinclair's ZX81 Service and Assembly Manual and circuit diagram SRC 049; ROM is 8 KB (infobox said 4 KB, contradicting the body), CPU clock is 3.25 MHz on every issue, X1 is a 6.5 MHz ceramic filter; remove the unsourced Issue 1/2 errata table, the Kansas City Standard tape claim, the 27 s/KB loading figure, the truncated 40-way pinout table and the wrong ROM keyword map) | ||||
| 05:05 | Template:Infobox computer diffhist +1,001 Josh talk contribs (Add the parameters pages were already passing but the template silently discarded - interface (37 pages), compatible (37), released (15), power (12), connectivity (10), graphics (9), input, rom, expansion, fpu, media, ports - plus alias handling and a parameter list, so that content reaches readers and refs defined in those fields stop vanishing) | ||||
