Offered here is a VERY RARE Commodore B-Series motherboard. The board is assembly # 8256068. This board would be used in the High Profile B-Series machines such as a 710, 720, 128-80 or 256-80. Looks like it was intended for the 256k models as it is already socketed for the extra RAM. The board is NOS and has been in my possessionfor over 15 years. It came from a Commodore warehouse after it was closed in the early 90s. The board is missing some chips but they are available from time to time on or elsewhere. The board comes in its original clear parts sleeve. I do not offer any guarantees that this works but there does not appear to be any damage on the board. Stock Photo. I imagine it can be made to function. Please check out my other listings. Buyer pays shipping. Will combine shipping. Good Luck!
