Atari Technical Bulletin TN002 - Mark - 07-22-2023
A letter to the dealers from Les Player n the introduction of Technical Bulletins including TN002
1 May 1986
Dear Dealer
I would like to introduce to you the first batch of Technical Bulletins. These will be presented
to you on a monthly basis, included in the Atari monthly News Bulletin. The object of the
Technical Bulletin is to pass onto you technical information that we feel will help you sell and
support Atari Products. The Technical Bulletin will contain bath hardware and software
information.
I would also like to introduce you to the Atari Technical Support Team.
Software Support - Robert Katz
Hardware/Service Support - Knolly Shadrache/Philip Wong Victoria Everitt
General Technical Information - Victoria Everitt
Customer Relations - Lucinda Bell
We would be grateful if you would avoid passing these names to end Users as we are all here
principally for Dealer Support. End User overload results in less capacity to help you.
Should you have any questions please do not hesitate to contact us. Yours sincerely
LesPlayer
Technical Manager
