Done all the patches & fixes ?
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 :D

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 disk somehow. I have .STX and .SCP of the original.

Silly Troed. The protection routine uses the IKBD processor. It will never boot unless you connect a keyboard :P Audio Sculpture original is working just fine.

2) My board has booted up in both WS2 and WS3 so far, so it accurately tracks the original in wakestates being "random". This is something I believe we can choose whether we want to continue doing, or simplifying for demo coders moving forwards by always using just one.

3) DMA is working just fine. I am currently booting off the internal disk drive, with drivers for the external Unicorn USB-ACSI adapter, and thus my normal USB stick hard disk.

edit: For clarity, I am using a 32.08xxx MHz oscillator so I expect full compatibility. If you're using 32.000 then a lot of advanced demo & protection thingies might bug out.

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.

I don't think you can set the time with CP.. you have to use the FMCII software to set it.

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 use then ;)

Its a bit of a faff. We have the same problem with flashyclock, in that CP wont work with it as its not supported by TOS / CP.

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.
