I'm sure there were a few, but have they been collected into a list? The only ones I know of are the Roland MPU-IPC and my personal Future Domain MCS-350, which is of a very low serial number. All of the chips sans the EPROM and the RAM buffer are TTL and PAL logic. Some of the PAL chips look to lack a security fuse by default, which may make producing a clone from scratch easy, or at least less of a hassle-- although I am nervous to desolder anything from it due to being a one of a kind.
