Chris, Thanks for taking the time to document this for me! -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com] On Behalf Of Chris Bongaarts Sent: Friday, January 28, 2005 9:12 PM To: firstname.lastname@example.org Subject: Re: Questions about SFD-1001 and IEEE Flash! As Fuller Dennis (RBNA/CIT3) once put it so eloquently: > 3. I have lost the manual for the IEEE Flash! which was a major > mistake. The IEEE Flash! has this white jumper wire that you have to > clip to one of the resistors inside the computer. I can't remember > which one! Is there a place I can order another manual or does someone > have a copy that they have posted online? I have the manual here handy, including the C64-C addendum. Where the clip goes: "Style 1: oldest C-64's, Assembly #326298 (number small)" Hook to the right side (looking from the front of the machine) of R44 (closest to front of a group of three resistors near center of board). "Style 2: newer C-64's, most common style, Assembly #250407 (number in white, front of electronics board)" Hook to front side (looking from the front of the machine) of R44 (leftmost of a group of three resistors near serial/video ports). "Style 3: newest C-64's, sheetmetal heatshield-cover, Assembly #250425, number in white, front of electronics board" Hook to right side (looking from the front of the machine) of R44 (center of a group of three resistors near center of board). SX-64 Hook to pin 7 of the PLA. "Locate the 6 pin and 8 pin connectors from the top front of the CPU board [which runs down the side of the SX-64]. The PLA chip is the second chip down just to the rear of the 8 pin connector... Locate pin 7 of the PLA chip by counting seven back, on the top row of pins of the PLA chip." C-128 Hook to pin 29 of the 8502 CPU chip. "Pin 29 is the ninth pin from the front of the C-128 on the right side of the 8502 chip. Pin 29 is the twelfth pin from the rear on the right side of the 8502 chip." Go through the right hand heatclip hole in the shield to get it to fit. "The new C-64C with the letters and symbols on top of the keycaps (PCB ASSY NO. 250469)" "Locate the fourth large chip from the left edge of the main electronics board (location U6 [chip is marked 8500])... Connect the white microclip to the eighth pin, from the front of the computer, on the right side of the chip." You might also want the DIP switch details (1-4, numbered from back to front): 1: Main on/off switch (right = on, left = off; reset computer to make effective) 2: Device 8 routing (right = device 8 routed to IEEE, left = routed to original serial bus) 3: Devices 9/10 routing (right = devices 9/10 routed to IEEE, left = routed to original serial bus) 4: Device 4 routing (right = device 4 routed to IEEE, left = routed to original serial bus) Devices 7 and 12-31 are always routed to IEEE. Devices 5,6, and 11 are always routed to the original serial bus. If someone wants to archive this info somewhere (e.g. FUNET) it would probably be a good thing. -- Chris Bongaarts email@example.com http://umn.edu/~cab Message was sent through the cbm-hackers mailing list Message was sent through the cbm-hackers mailing list
