Alot of stuff has gone over the dam since Atari was founded.
The first CDRom drive known as the CDAR and the transputer which ran with multiple processors known as the Arabaq or some such name. The first CD Rom software written by a group in Arizona. There were a lot of 1sts and lasts.
The main problem was that there was too much compatibility between the various machines. The operating systems should have been staright out of the box 1.0 and then 1.4 and 2.0 etc but not backward compat. Do like IBM style boxes when the operating system gets old go with new and better updated. Make the customer buy new or do without.
Another problem was Atari's support, for the last two to three years of support all I could get was vouchers for time and energies expended. Trade tech work for parts etc. and hope to come out clean. In the last two years no cash swapped hands, just parts and machines.
Then there was mass marketing. My service center had machines from Toy R Us to be repaired. Then my store would purchase machines for resale at prices higher than Toys R Us was charging across the board. My price $350.00 before resale, Toys R Us 275.00 to 280.00 at resale.
I still miss Atari and will continue to use what I have. Usually beats the PC hands down for what I do.
