This post has been left for historic information. The PET microSD is no longer in production. The replacement SD2PET is available now, more information on the pre-order page.Here is a bit more information on installing one of my new PET microSD Commodore PET disk drive replacements inside a Commodore 8032-SK or 8096-SK.
2022 Update: I have since designed a much nicer SD drive for a PET. The SD2PET is available from The Future Was 8 bit Note there is not a version which will fit the 8032-SK.
