Is there a startup sequence for the ST somewhere ? I saw on TF channel he was running assembly output in real time from the CPU, wasn't perfect, but saw it access the pallette register early on... so assume it sets the screen all white at some early point...
Mostly black screen is bad, but white screen means TOS is actually trying to boot.. I think...

Re: PCB Build - Progress - Post your Pics here :-)
I have noticed something else.. I haven't buffered MONO output from the shifter.. so hi-res monitors may not work...

I agree this is the main reason for me getting the board too.Forgottenmyname wrote: ↑Mon Sep 17, 2018 7:39 pm See, I learn something new every time I turn this board on, which is one of the reasons I got it
I am getting 15.6kHz and 50Hz out of the Glue. It initially is 60Hz then immediately goes to 50Hz as mentioned by Troed.
Re: PCB Build - Progress - Post your Pics here :-)
Seeing this I thought I would switch the board to my mono adaptor to check and got no signal on the monitor. At first try it seems as you mention that hi-res is not working.
Re: PCB Build - Progress - Post your Pics here :-)
I probably didn't bother with it much on this version as RGB output was more the thing to be tested,, A buffer could be added as a addon easy enough if needs be, but think its not really important right now

Re: PCB Build - Progress - Post your Pics here :-)
I've modded the next schematic ...
This could be built, but would need the track cutting for MONO pin from the shifter, or pin bending up...
IMHO not to important right now.. but its simple if anyone wanted/needed to do it.
Bottom layer track..

Re: PCB Build - Progress - Post your Pics here :-)
Great work. Mine is still on a black screen with sync issues even after the patch. I am going to check out the soldering etc a bit more and also try a different SIMM as it might be duff.Forgottenmyname wrote: ↑Tue Sep 18, 2018 11:08 am BOMBS, we have bombs!
