I don't think this is a real VME bus. Maybe based on it, maybe 2 of the 4
backplane connectors are VME-based. I don't know. What i found out for now:
The power supply is capable of a load of 5V/180A, 12V/26A, 12V/3,5A. nice
values. This is the reason for the very strange power connector of these
machines. The other thing: It hat one 88100/25MHz and 4 PMMUs. The RAM (32MB)
consists of several hundred chips, which are really needed completely, so RAM
control will be a very big performance gain here. Every I/O card has it's own
68020 on it, so also here, the performance will be very nice.
But maybe... we need to write kernels for the I/O hardware, as i saw this on
the PCS Cadmus machines i have standing around.
For the Triton: I heard, only 250 of these were made, i have 2, and i just
checked it... they have the serial numbers 10124 and 10125, but i got them from
different sources... Seems to be very rare, really.
Currently... hacking the pinout of the RJ45 console connector :) But the beast
boots and talks to me, it just doesn't listen to me on the console...
