Can you do some tests and see if the Prisma Megamix is compatible with those 4-way clockport expanders that were released few years back?
I think there will be plenty of A1200 users that will be interested in your Prisma Megamix sound card but won't necessarily be prepared to sacrifice their Subway USB card for. As those 4-way clockport expanders are no longer being produced will you please consider a new production run for your customers, I believe the blueprints are freely available on the internet.
