I was ONLY talking about the "CP" serires. Not CPXXX. So the M233ST etc...
Those are all considered CP series machines (because, you know, they all contain CP in their names and use the same C-series bays and accessories), and technically, the CPM and the CPiDs are the same exact chassis - same motherboard, GPU, RAM type, all that. You can in fact swap MMC1 CPU modules and go from the Pentium MMX to the PII Mobile easily with the use of the TR4 BIOS and turn them from CPM to CPiD with about 5 minutes of work and 2 BIOS flashes (one to TR4 and one away from TR4). And yes, I did that many years ago and it was a practical way to buy a CPM on the cheap and then upgrade it to a Dixon-128 Celeron later for a very decent CPiD class machine.
You wouldn’t believe how many people come into Vogons asking for help on DOS audio support on CPs that turn out to be either CPiA or CPiR even though it was mentioned time and again that only the first 2 and the last machines in the CP series have full DOS audio support. It’s almost like NO ONE uses that search function before they post questions.
