worked on sales and we have agreed to make a wholesale price of $ 500 for shopping. What was supposed to be the retail price? It's simple - add one third of the wholesale cost. I got out an amount of 666, 67, but this is only at the end of 7 prevented and in this we have decided to replace it with a 6. All costs consisted of one digit, repeating several times. This figure was more easy to remember and perceive. We then thought about the religious significance of this chisla.10. As of June 2015, only 66 Apple-1 units still exist, according to the online registry Apple-1. Woz was the only one in the company Apple, who could provide support for Apple-l. For this reason, in 1977, when he left Apple-ll, all users of Apple-l was given the opportunity to replace their current legacy platform to a more modern version of the second. Most of Apple-l has been destroyed by the company itself.
