If you intend to use the control, make sure it has the G-code
option, otherwise it only has Heidenhain's proprietary language.
It should have enough memory to hold a modest program without
drip feeding.
If considering it for retrofit, it may have analog scales or encoders.
You can convert these to logic signals but it takes a bit of
hand wiring a converter chip to do that. It may be better to
replace the encoders with modern, higher-res units.
And, certainly consult with Igor Chudov ("ignoramus" he is NOT!)
who has one of these and is happy with his conversion.
If you really want to make parts with it, I'd strongly recommend
a retrofit for two reasons. My experience with old controls
(as in over 20 years of age) is they are a lot of trouble, with
several breakdowns per year. And, the newer controls offer a bunch
of advanced features and better performance.
