Some programs, for compatibility reasons, may require the computer
to run at 4.77MHz. Try changing the CPU speed with the switch on
the front panel. See “Selecting Execution Speed” in Chapter 2.
Printer Problems
Most of the problems encountered while using a printer can be solved by
checking the manual that came with the printer. If the printer is not working
correctly and has just been installed, first make sure the printer has power
and is correctly connected to the computer. The printer manual provides
instructions on cable connections.
If you have a serial printer, or if you have problems with paper feeding,
you may also need to check the printer manual for the correct DIP switch
settings. The DIP switches on a printer help it communicate properly with
the computer.

Did you set any necessary DIP switches on the main unit? See “Setting
the DIP Switches” in Chapter 1.
Did you change any necessary jumper settings in the main unit? See
Appendix A, “Changing Jumper Settings.”
If you added an external device, did you use the proper cable to connect
the peripheral to the port or option card connector on the rear panel?
Did you perform any necessary post-installation setup procedures for the
operating system? See your Diagnostics, MS-DOS, or other software
manual for instructions.
