Not really. As I said, Sun and Axil, while using the same 12-pin power
connector, put the pins in different positions and color code the wires
differently. For the 220, Axil also sourced the PSU from a different
vendor and it is a completely different size (almost the same size as a
flexatx psu). Also, only 10 of the 12 pins are used.
The Sony PSU used in pizza box sun4c system changed from black
(GND)/red(+5V)/yellow(+12V)/blue(-12V)/orange(+5V POR) to
black/red/blue/brown/gray. The sun4c lunchboxes used the same connector
except they started call the orange/gray pin SENS (is that the same as
POR in Sun's usage?). The sun4c lunchbox scheme continued through the
sun4m lunchboxes. The sun4m pizzaboxes went to an 18-pin power connector
with the same wire color scheme, except gray became "PwrOff"/"Poff".
The PSU in my Axil 320 (a SS10/SS20 clone) uses the 18-pin connector and
a color scheme similar to the SS10/20 one but I haven't checked all of
the pins to see if they are completely the same.

Does anyone here have a running Axil 220 or 245 (Sun SPARCstation LX clone)?
My 220 has a dead PSU and I am trying to get it working with a modern PC PSU.
But I don’t know the pinout for the power connector.
While the power connector is the same as used by Sun, the pinout and, aside
from +5V and GND, the wire color scheme are different. I have identified 3 of
the 6 wire colors and 7 of the 10 pins. The wire color scheme seemed to be a
match for early sun4c but I just found something that suggests a couple wire
colors are used differently.
I have found that black is ground, red is +5V, and yellow is +12V. White,
orange, and blue are TBD. A marking on the PSU board suggests white is -12V.
Blue and orange seem to only used by a daughter board centered on a LM339 chip.
But, as a software guy, I can’t tell what it does.
Anyone here have any insight here that might help me?
