I'd always understood the order to be FB, PM, AH, JM, JS, MGx; I think I read that in an early edition of QL User. PM was supposedly never released. FB allegedly stood for "Full of Bugs", AH for "Angela's Holiday". Not sure about the others... I had an AH QL (s/n D06 IIRC) from new in about June or July 1984, if my beer-addled memory serves me correctly. Sadly, one of the soldered-on chips on the AH board has given up the ghost (which had some hand-soldered modifications), but the AH chips live on in another, newer, board. Cheers!
