I just found the receipts for my original A1200, bought new in Feb. 1993.
The computer was $628.xx with tax, then the MBX 1200 w/4Mb RAM was $364.xx - and the Hard drive was another $302.75.
Obviously I really wanted that computer!
This was about the 10th machine that this shop received in '93 - and there was a crush trying to get one (in this area, anyway).
I just sold that machine less than a year ago - it's still working fine, as far as I know (although it had been upgraded over the years)
I also found a receipt for a GVP A500 II Hard drive/RAM unit with a 120Mb Quantum, and 4Mb of RAM cost 721.38 w/tax (another local store - Buried Treasure in Rockville Maryland - an Amiga Super Store in its day.
