As you've seen, my board is up and running in the H4. I've briefly verified that it's not fully compatible with my fullscreen routines - is there some knowledgebase I should start off from or should I just start to document function vs expected?

After a bit of searching I found a complete package with 20V8 JED and schematics to build up a MegaST compatible RTC. I've ordered a few RP5C15 and might try to build one up on my H4. I know there's major development done in a different direction for the remake, this is just something I do for fun f...

With a CPLD on the bus it shouldn't be too hard to make it Mega ST compatible though? Then TOS would indeed support it. Job for you then ;) The RTC chips are totally different.. parallel <> serial for starters. Just easier to just let software do it. Sure, if wanting to make it Mega ST compatible t...

I don't think you can set the time with CP.. you have to use the FMCII software to set it. https://www.exxosforum.co.uk/forum/viewtopic.php?f=25&t=1683 Ah! I just assumed it was Mega ST compatible, don't know why I thought that. It seems that DallRTC is a wonderful piece of software I should us...

Hmm. I don't have a functioning battery backed up RTC it seems. At least setting time via Xcontrol, turning off and then on again didn't keep.

Some early findings: 1) Audio Sculpture v1.3 original does not boot. If I were to guess, it would be the protection routine changing resolutions and confusing the HDMI Shifter board, not the H4. Someone with regular video could try to see if it starts, but you need to write a protected version to di...

Total brain fart on my side. Somehow I read the bgack fix as something only needed for the expansion slot the soldering was done to. Proper sleep helped

So what exactly happens on boot? Black screen? White screen? White border with black centre? Well, the only video circuitry I have is the HDMI board. It lights up (red led) and I _think_ it's just then sending empty frames to the monitor. What this would mean in ST analog output I don't know. I've ...

Ah, thanks. Both jumpers now open but same same. Tomorrow will be microscope and LA day.
