A friend of mine did this Techno 4x8 retofit. Since the Techno servo board blew and the customer didn't like there controller, Lenny put 3 (older style) Viper servo drives and one of my Starcam controller boards in.
Almost No mods were done to the Techno servo cables, since all we had to do was make a little DB15 to DB9 adapter on the encoder cable.
I'm suprised they used little 50 In/oz size 23 motors on all axis, on a 4 x 8 machine . But the machine runs nice and smooth once we tuned it.
(BTW,The drives in the picture are some of my old 1st gen prototypes, but run it fine (i sold them cheap))
The Viper 95 would be the perfect drive for this machine, using Mach3. Its an fairly easy retrofit, since the limit switch also comes down the encoder cable.
Anyone interested, I can give them the connections for the adapter.
