iMac G3 (slot) mod : problem with Video Connector Wiring
Hi,
I have been trying (to no avail) for the last few days to include a mini ITX-PC board in an iMac G3 slot-loading while keeping its PSU and CRT.
I made a short custom cable to internally connect the VGA output of the PC board to the iMac HE10 20-pin video connector but it looks like I am still missing some pins.
Even when the +5V-trickle (T5V) and PFW signals are shorted, I cannot hear the "PONK" sound of the CRT charging up ... (needless to say that the CRT works quite right with the original iMac logic board).
Has anyone made such a mod and did you find out if pins 4, 5, 7, 8, 12, 19 and 20 have to be connected and where to ?
Thanks for any help you could give me on this issue.
