This is not completely true! CHRP clone makers (both UMAX and Tatung had
working LongTrails in 1997), including Motorola, decided not to bring CHRP
boxes on the market mainly because Apple refused to license MacOS. They all
wanted to make money from selling Apple clones, and weren't convinced that
there was a sufficiently large Linux on PPC market (remember, it was 1997, i.e.
before the Linux boom). Not to speak about NT, AIX, Solaris and OS/2, which
were all marginal compared to MacOS.
The hardware was ready. Not only did you have the LongTrail (designed by IBM
around the VLSI Golden Gate II chipset), but also reference designs from
Motorola around its own MPC106. IMHO the GG2 wasn't a bad host bridge. It
lacked AGP, but AGP wasn't so ubiquitous present in 1997 anyway. SDRAM ran at
66 MHz (on my board), but this was boasted to 83 MHz on later boards.
I ported Linux to the LongTrail (http://home.tvd.be/cr26864/Linux/PPC/) just
before Apple cut the MacOS wire. The LongTrail is still my main machine, and it
proved to be very stable.
The problems started only after that: no PPC boards (besides Apple, embedded,
and high-end IBM), hence no further development of new host-bridges.
