How much is an original InnovaSON SC-Optical V4.0 / SC-64 card worth today?
Hi everyone,

I recently created an Audiofanzine account because I am trying to find some information about an old InnovaSON card that I have and may want to sell.

I have already done quite a bit of research myself, including looking through old InnovaSON documentation, but the market for these cards seems to be extremely small. So I thought the best thing would be to ask the community here, especially anyone who has worked with InnovaSON systems in the past.

From the information I have been able to find, I believe the card is an original:

InnovaSON SC-Optical V4.0 / SC-64

The markings on the PCB are:

* CU4069_2 (MC/SC Optical)
* S36/04
* SF2069-003
* N° 249

The three EPROMs are also present and appear to match the SC-Optical V4.0 configuration:

* U9 – SC 4.0 / 5803
* U102 – SC 4.0 / 8777
* U105 – SC 4.0 / CFF1

I have attached several photos of the board and the markings.

As far as I understand from the old InnovaSON documentation, the SC-Optical was used on the Stage Box side of the system and handled the digital audio transmission between the Stage Box and Mix Box.

What I am trying to find out is:

What would be a realistic current market value for this particular card?

I have found very few examples for sale. The closest comparable I found was an InnovaSON MC-64 Optical card offered for around €300, but I understand that the MC and SC versions are different and I don’t want to simply use that price as a reference.

Based on the limited information I have found so far, I was considering listing mine at around €449, but I would really appreciate the opinion of people who know these systems better than I do.

In particular, I would be very interested to know:

* Has anyone here owned or worked with an SC-Optical V4.0 / SC-64?
* Is this particular CU4069_2 / S36/04 revision associated with a specific InnovaSON system or generation?
* Are these cards still sought after as replacement parts?
* Have you seen any actual sales, rather than just asking prices?
* And most importantly: what would you personally consider a fair price for this card today?

Unfortunately, I currently don’t have a compatible InnovaSON system with which I could test the card, so I would have to sell it as untested. Visually, however, it appears to be complete and in good condition, with all three SC V4.0 EPROMs installed.

If anyone has additional information, documentation, old price lists, previous sales, or even remembers these cards from working with InnovaSON systems, I would be very grateful for any information.

Photos: The close-up photos show the PCB identification and all three SC V4.0 EPROMs. If anyone needs photos of a particular area of the board to identify the revision or components, I can upload more.

Thanks a lot in advance!
