22:25 (cur | prev) +2,729 Josh talk contribs (Rewrite from Individual Computers' and Daniel Mantione's own pages: the PLA is a 28-pin DIP at U17 on long boards but a 64-pin 251715/252535 at U8 on the 250469; SuperPLA V3 explicitly does NOT support 250469 and is EOL; remove the unsourced CPLD/FPGA comparison table and the PLCC-puller instruction) | ||||
| 20:25 | JiffyDOS Kernal Upgrade diffhist +4,658 Josh talk contribs (Remove the live ChatGPT citation placeholder; the 124 s to 12 s figure is real and is now cited to CMD's own JiffyDOS V6.01 user manual, with both of its full timing tables; correct the claim that the 1581 gains least (it gains most in 64 mode); correct the licensing section - RETRO Innovations is one of four authorised channels, not the exclusive licensee; remove the dated price list and the unverified 1985/1990 dates; state the exact ILLEGAL DEVICE NUMBER tape behaviour; add the ROM-switchi...) | ||||
| 20:10 | Commodore 64 Power-Supply Protector (C64 Saver) diffhist +3,008 Josh talk contribs (Rewrite from Ray Carlsen's own description: the Saver is a fast-acting circuit breaker that OPENS the +5 V line, explicitly NOT a crowbar; fix the bench-test pinout (pins 1-3 are ground, +5 V is pin 5, the page had +5 V on pin 2); correct 'epoxy-potted switchers' to linear supplies; explain why the trip point is 5.4 V; remove the unverifiable variant/trip-point/BOM tables; drop the non-existent category and red link) | ||||
| 19:58 | Commodore 64 diffhist +4,366 Josh talk contribs (Cite to Commodore's own C64/C64C Service Manual; correct the board-revision table (250425 is a long board, version B, not a C64C board; 250407 is version A; identifying factors are Commodore's); add 6510 Vcc pin 6, SID audio pin 27, user-port 9 VAC pins 10-11, DIN pins 1-3 ground, $C000-$CFFF is plain RAM; hedge the units-sold range; remove red links) | ||||
