Been reminiscing lately about my teenager years and involvement in a major C64 warez group (days long gone but I miss you 80's) and wanted to replace my now long gone gear.
First I scored a Commodore 128D with no yellowing or anything, and the guy selling it didn't know anything about it (estate procurement) but when it arrived it was missing the keyboard.
Then I happened on someone selling a VIRGIN Commodore 128 and 1571 drive. They were in the original boxes with disks still sealed, original cable ties the whole ball of wax. They had been sitting in their boxes and wrapped in plastic somewhere for 25 years (mfg date 7/86).
Finding this stuff without yellowing is practically impossible.
