Original Pricing, Production Information courtesy of Robert (4/2010): "I've just been clearing out our loft and found some old receipts. Amongst them was a receipt for a Commodore SR-9190 calculator bought by my dad for my brother on 18 November 1978 for 24.75.  I would guess this was an average retail price for it then."
