Hello,
I found a copy of the Phoenix Manual. The jumper configurations are not well documented.
The manual stated that Kickstart 1.2 will not function , you must use Kickstart 1.3 there are also problems with Non Motorola 68000 CPUs.
The Kickstart ROM should be in ROM#1 and If using an external A2000 Card set the jumper as follows:
L15, L18, L19, L117 (All Off)
Shaf
The Rejunivator Baord was a lot less complicated than this. The again the Phoenix has more features, 8 MB Ram expansion (optonal Board), Internal HDD etc.
