I assume it is possible to take the hard drive out of my MkII and drop it into an MkIIa (taking out the original drive). Now that I have a wealth of MkIIa's I would like to take my MkII out of service to preserve it for posterity.

Also, my car required the negative spike diode fix. Will the diode I installed interfere with the MkIIa and it's onboard diode?
