TANDY 1000 RSX  (250-1454/55)     Expansion Board       Faxback Doc. # 1239

The Tandy 1000 RSX System provides two expansion slots that let you add 
special accessory boards. If you choose to add a modem board, you can 
communicate with other computers through the phone lines. Add a facsimile 
board, and your Tandy 1000 RSX System is quite simple. Once you familiarize
yourself with the following procedure, you can install any type of 
expansion board. Read the instructions that came with the expansion board 
kit, and follow these directions:

Note: Refer to Faxback Doc. # 1312 for location of Expansion Slots on Main 
Logic Board Layout.

Note: The top expansion slot will hold a 10-inch expansion card, and the 
bottom expansion slot will hold a 7-inch expansion card. Be sure the power 
is off and cables removed before proceeding with the following steps:

1. Remove the back cover screw and the back cover. (Save the cover in case 
   you remove the board.)
2. Align the expansion board with the open slot.

Note: If your expansion board has a straight edge, it is not necessary to 
feed the edge through the open slot.

3. Using both hands for support, press the expansion board into the riser 
   card. Make sure the expansion board is well seated.
4. Use the screw that was previously removed to fasten the board to the 
   back of the computer.
5. Close the computer and reconnect the cables. Then, restart the computer.
