I recently acquired a 12th week 84 M0130 External Drive with an OA-D34V inside. The drive was stored well and is in excellent condition. After servicing it, I tested it on a 128k and 512k and no issues so far. My dilemma is whether the OA-D34V drive unit is more valuable to put into a 6th week 84 128k I'm trying to restore OR leave it in the external case. Otherwise, I would opt to put an OA-D34V-22 into the 128k but not sure if it will work with early ROM's (I can test this of course).
