Hi everyone,
I have been trying for the last few days to include a mini ITX-PC board in an iMac G3 slot-loading while keeping its PSU and CRT (sort of nostalgic 'vintage' thing , I guess ....).
I have made a short custom cable to internally connect the VGA output of the PC board to the HE20-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 can share here or by PM.
