Question AKG BAP1000 Digital IO

Hi there,

First, i'm not well versed in electronics, especially digital stuff.
I have a AKG BAP 1000, which is a digital headphone processor from the early 90s. Unfortunately the "digital" only refers to the internal processing. The in- and outputs are analog only (symetrical). However, there are holes and labels for digital input and output, each optical and coaxial on the back of the device and the motherboard has a pair of jumpers labeled DIO and not DIO (which could mean DigitalIO). An AKG employee told me, that a digital IO Upgrade was planned at the time but never released.
My question: Is it in principle possible, to retrofit digital input and output (optical or coaxial) to the device?

I don't have circuit diagrams, but i'm trying to get them from AKG. The DA converters are Burr Brown PCM56P, the AD converter is a Burr Brown PCM78, all are mounted on sockets. If required i can upload a photo of the motherboard.

Thanks in advance for your help and greetings from Wiesbaden, Germany,
