This is a Partner 1, don't know where they get a phase 1. I doubt it is a single phase machine. I don't think they had Single phase spindle drives back when this was made.Originally Posted by Stuff-Builder
I'd guess it to be from 1987.
I wonder who diagnosed it had a motherboard problem. There is not much on the MB for these machines. I'd be interested in knowing their definition of motherboard too. If it is the Acro motion controller or the Sim-drive, I'd say the price was already too high. It is not economical to upgrade to a hard drive and not much better to get another sim-drive card, IF they can even still support them.
The other machines description of a wiring problem contributing to it being under powered is odd. They know something is not right with it.
It may be worth 2g's for a gamble that there is only a bad sim-card battery and all it needs is a reload. Controller parts don't come cheap from OEM's, so there could be another $3000+ worth of parts required to make it run.
I certainly wouldn't buy it sight unseen unless you plan to fit it with another control. On those terms, I'd say the iron of an old Boss machine would be a better buy. At least with a lot of the older Boss machines, the control often died before the iron was too worn. On the Milltronics import iron and the rest of the driving elements may have taken a lot of abuse over the years it did run well.
The one we have very similar to this is a 1990. You can hear the Y-axis screw from 75ft. Amazingly it still makes parts within a couple thou.
