I got a new batch of White and black pcbs. noew the Rev 1.4 version..
Rev 1.4[FONT="] – 74LS166 Pin 6 and 8 should be connected to Ground![/FONT]
[FONT="]Also made changes:[/FONT]
[FONT="]Moved some traces being close to edge and vias, some boardhouses had issues with this.[/FONT]
[FONT="]Added headers close to 0Ohm resistors for audio, so you can skip the 0Ohn resisors and do own “mixing” if wanted.[/FONT]
[FONT="]Moved onboard leds some, so they will not short to a diskdrive. Also added headers for leds if mounted in a Tower.[/FONT]
[FONT="]At powerconnector, added pads for a ferritebead, so if using a round powerconnector the N/C pin can be used for ground. (NOT for use on square connector)[/FONT]
[FONT="]At A500 keyboard connector, exluded the extra HDD signal for the key. if wanted, you add a 1Ohm resistor at back to enable function.[/FONT]
[FONT="]Removed 3 0Ohm resistors at alice. (made them onboard instead)[/FONT]
