somewhere I've heard that it's not possible to write
programs in assembler code for the 3DO - true?
And if so, why?
(Anyone fancies to write an assembler code Doom engine,
using the Doom2.wad, the music of 3DO Doom 1 and include
a link option via the expansion port...?

I don't know whether you absolutely could not write code natively for the hardware or not, but I do know that 3DO encourage developers to write code for the 3DO Operating System. This is why John Carmack was a big fan of the Jaguar and not the 3DO. Since on the Jag you could write code straight to the hardware.

I've written some assembly for FreeDO. I see no reason it couldn't be done for the hardware. It's possible you could see some funky incompatibility with the different hardware iterations, though.

Compatibility-issues are interesting.
I've heard of some games that are said not to work on Goldstar
But I am really wondering why?
I thought, each model was built using the same given technical
specifications and plans, provided by the 3DO company.
Okay, the PCBs look a bit different, but that was only due to optical
design for the consoles body-shape.
If they really *were not* technically identical - is that also the reason
for all the different BIOSes? And what exactly *are* the specific
differences in the PCB (except for the layout)?
PS: Sorry for my crude English. I just cannot speak properly today... :-/

My guess is that each iteration of the hardware was built closely, but not perfectly, to the specification. Bugs, basically.
As for the different BIOSes, I haven't compared any, but my guess would be that the differences are mostly just cosmetic. Each company wanting to put their own logos in, etc.
I know nothing about the PCBs. Sorry.
