83-84 Volvo 240 ECU ECM Bosch Jetronic Computer 0280000510 New old stock

Volvo 240 ECU Up for sale is a new old stock Volvo 240 Engine ECU. Part number-- 0 280 000 510 (0280000510). This unit is the original for many 83-84 240 non-turbo 4cyl model.   This unit has never been installed to my knowledge.  - however it may have been plugged into a car a few times for test purposes- It was in a "shop parts stash" of an old volvo technician whom had recently passed away.  Offered up here for pennies on the dollar of the Bosch MSRP.
