Has anybody ever tried removing the onboard CPU in a machine like the 6100 or 6400 and installing an L2 or PDS CPU upgrade card? Would one or both of these types of CPU upgrade work? Theoretically they both attach directly to the 60x bus and somehow completely take over the bus and/or disable the onboard CPU, which should mean the upgrade card has full access to ROM and other devices even at initial boot.
Mostly I'm wondering if it would be possible to take the processor out of, say, a 6100/60 to safely be able to crank the original 30MHz bus to 40MHz without worrying about the original CPU being overclocked and consuming power/producing heat when it isn't doing anything useful. I have an 8100/110 board with a damaged CPU that I could use to test this (and up its 37MHz bus to 40MHz while I'm at it) but I'm curious if someone else has already been there and done that. The only concern with my 8100 board is that it has a warning that the Peltier junction needs to be connected or the board may be damaged, but it doesn't specify if this would be electrical damage from the lack of a load on that circuit, or if it's because of potential overheating damage to the processor, which won't be an issue since it won't be installed.
