As I said here:
https://forum.amiga.org/index.php?topic=76166.0 I purchased an A4000 in great condition. However, I believe in the saying, "If it ain't broke, fix it til it is." I am fascinated by the new A4000 PCBs that have been offered. It's a replica of a Rev B motherboard. Has anyone tried one of these? Good, bad, indifferent? One vendor has them completely built, NOS custom chips, new connectors (except the DB23 which is recycled). Kind of pricey, but very tempting just the same.
