I think it wasn't until Commodore started outsourcing some of the chip production that they moved to CMOS. If I understand the MOS numbering scheme correctly, all 8xxx-Chips are HMOS-II. I wasn't able to confirm it anywhere, but from the absence of the ICs getting warm, the 5xxx-Chips (I know of 3 with a 5xxx number) should be CMOS. Later MOS/CSG unfortunatly abandoned the easy to remember four digit numbers and just printed the Commodore part numbers and/or names on them.
