I think the pheonix bios did more than Compaq did. The hardware was all
very well documented by IBM before the clones started coming out, as was
the BIOS. People didn't used to try to hide that sort of thing. :-) IBM
wanted people building cards for it, just like Apple did for the
Apple ][.

Yep yep.

I dunno about that. Worked well for, say, manufacturing plants in China.
I don't know that it worked well for people actually selling the end
product.

Yeah. Except I think you're confusing Phoenix with Compaq. Compaq made
the hardware. Phoenix cloned the BIOS first. (Unless I'm misremembering
something.)
And yes, IBM *did* sue over it. That's why Phoenix followed the
clean-room approach to start with. The original IBMs came with a
complete commented source listing of the BIOS when you bought them.
(Well, maybe it was an extra packet, part of the assembler or something,
but it was an off-the-shelf purchase.)
