- Looks like you are pull-up resistor blind. Can all registered uses please login, even just for a few minutes..
It helps build a picture where our "good traffic" is coming from..
Thanks :)

Must be, reverse of OCD I guess...
Re: Icky - Progress
So looks like the keyboard fix pull-up has actually fixed the sound.
Also in doing the diagnostic cart the DMA Port Test comes back with:
Code: Select all
DMA Port Test
D0 DMA time-out
Fail at cycle:000001
Re: Icky - Progress
I think you need a special cable for DMA test...
Best thing is to put a blank floppy in the drive and try the floppy tests (it formats a floppy somewhere)

Well many of those tests require a test harness connected to the ports that route signals back.Icky wrote: Tue Sep 25, 2018 10:59 pm Also in doing the diagnostic cart the DMA Port Test comes back with:

Re: Icky - Progress
OK so 2 images posted for the ACIA BUS FIX... hopefully that will be the last one... nothing like ending on the worst fix!

DONE - And we have keyboard and mouse. Video shows changing to medium res but the floppy is not accessing the drive correctlyexxos wrote: Tue Sep 25, 2018 11:28 pm OK so 2 images posted for the ACIA BUS FIX... hopefully that will be the last one... nothing like ending on the worst fix!
Exxos - I doff my cap to you for all your hard work
Re: Icky - Progress
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..

Pulled out resistor pack as I SILed them. Still no joy. Its accessing the drive but not seeing it properly.

Unbelievable. Hats off guys, you made it working in like what, two weeks? Amazing.I guess the video also shows the screen flashing? Or is it just an artefact by recording?
