BUGS & BYTES....

by Mike DesChenes

As far as price, flexibility, performance, and hardware are concerned, I consider the Atari computers to be the best on the market. And because A.N.A.L.O.G. is concerned only with the Atari computers, this column will be short lived. However, if you have any problems or questions no matter how minute they may seem to you, drop me a line and I'll try and include it along with the remedy in this column.

Occasionally a number of early Atari's have given their owners quite a scare because of a very minor problem.

SYMPTOM: You turn your system on and out of the clear BLUE sky ... nothing! (Well, almost nothing). just a dark blue screen (depending on your monitor). You bang it a little, turn it off and on a few times, and finally it surrenders with "READY". Other than a complete meltdown, I can't think of anything more frightening.

CAUSE: If you were to look inside the 400; (1 wouldn't recommend it if your warranty is still in effect or if you're not mechanically inclined); or take the door off the 800, you would notice the ROM and RAM boards. In the 400 you would see two vertically mounted PC boards, which are the RAM and CPU boards (The 800's CPU board is mounted internally in the area directly behind the third RAM board slot.) Actually the 400 and 800 both use the same type of RAM board. Contained in the 800's 8K RAM cartridge is the same board that you would find in an 8K 400 (give you any ideas?) The problem stems from the edge connectors on either or all of the boards. Oxidation because of humidity or other environmental conditions, may cause a bad connection between the boards and sockets.

CURE: When taken to one of the Control Data repair centers, they remedy this problem by simply removing the boards from their pin connectors and gently cleaning the surfaces of the board pin contacts and lightly coating them with "Lubiplate" (available at many industrial electronic part suppliers.)

If you have previously had your Atari upgraded or serviced at any one of the Control Data repair centers, then it would be safe to assume that the above specifications have already been performed. Which proves to me that Atari and Control Data are working closely together to maintain the high standards of excellence that Atari owners have come to expect.

NOTE: I have noticed that most of the newer 800's have been shipped with gold plated edge connectors on the RAM and ROM boards, and according to an Atari official, the 400's will be coming through the same way.

 

HAPPY BIRTHDAY

How old is your Atari? Three months? I don't mean how long have you been the proud owner, but how many days, weeks, months, have gone by since it was built? Who cares? Well, it may not be as important to you as the new Asteroids cartridge, but admit it, you must be a little curious.

The 800 which I constantly use has the serial number 490. Some of the later ones also have the first three numbers with WW preceding them (Example WW490). These first three numbers tell the year and work week that your computer was built. The first two numbers designate the work week, in this case the 49th. The third number (0) tells you the year (0 = 1980, 9 = 1979 and so on.) You can also read your serial number in the same way on the Atari disk drives. I'll bet that the next few minutes you'll be taking a peek at your serial number.
