Our ticket system does state on the webpage that responses can take up to 48 hrs. We have many Support queries on a daily basis and it can take many hours of our working day to respond to each one. In addition, we also pack and despatch packages, repair Amigas, assemble Amiga systems and test/install hardware for customers, so our working day is busy as you can imagine.
As regards the new firmware on the ACA 620- this requires transporting to Germany in customer batches to be reflashed with the new firmware by the manufacturer. It does not make economic sense to send a single card.
We have already sent one large batch before Christmas and received back. We are preparing for the second batch.
