Must be, reverse of OCD I guess...
So looks like the keyboard fix pull-up has actually fixed the sound.
Code: Select all
DMA Port Test
D0 DMA time-out
Fail at cycle:000001
Well many of those tests require a test harness connected to the ports that route signals back.Icky wrote: 25 Sep 2018 22:59 Also in doing the diagnostic cart the DMA Port Test comes back with:

DONE - And we have keyboard and mouse. Video shows changing to medium res but the floppy is not accessing the drive correctlyexxos wrote: 25 Sep 2018 23:28 OK so 2 images posted for the ACIA BUS FIX... hopefully that will be the last one... nothing like ending on the worst fix! :lol:
Jumper swapped and working with other TOSexxos wrote: 26 Sep 2018 03:24 Yay!
Might be worth unsoldering the resistor pack next to the 1772 ( should be 10k).. And see if that helps.
Also swap the tos jumper as looks like your running 102 there..
:o Unbelievable. Hats off guys, you made it working in like what, two weeks? Amazing.Icky wrote: 26 Sep 2018 00:23DONE - And we have keyboard and mouse. Video shows changing to medium res but the floppy is not accessing the drive correctly
