By the time of the never-quite-delivered BoXeR Amiga-replacement that ALL-in-ONE Chip Form had actually come to pass.
You have to look at the timeframe. The ORIGINAL Custom Chips existed as whole Breadboards requiring a complete Airline Seat for transport in their Prototype-Form in 1984.
The BoXeR was being developed in 1996-98.
Early Mobile Phones were the size of Cordless Phones, only LARGER, in early '90s timeframe.
Early GVP Accellerators+SCSI+RAM required two physical boards. That's why there is a W-I-D-E gap between the CPU Slot and the first ZorroII Slot in A2000s.
