Free Modification for LEVEL II Units
A modification that helps cassette loads in LEVEL II computers is available
free to TRS-80 LEVEL II owners. This modification makes the volume setting
less critical so that variations in different tapes usually will not require
volume readjustments.
Some of the more recent LEVEL II Keyboard units have had this
modification factory-installed. To see if the modification has been included in
your computer, look at the catalog number on the bottom of the keyboard
case. The modification has been made if the number ends in -1. For example,
if the number is 26-1004-1, the modification has already been installed; if the
number is 26-1004, the modification has not been installed.
If the number does not end in -l and you have not already had the cassette
modification installed by Radio Shack, you may arrange for installation at
your local Radio Shack store.
Using Your Cassette Deck
Many factors affect the performance of a cassette system. The most
significant one is volume. Too low a volume may cause some of the
information to be missed. Too high a volume may cause distortion and result
in the transfer of background noise as valid information.
Three different cassette models have been supplied with the TRS-80 system
the CTR-40, CTR-41 and CTR-80. Each model has its own loading
characteristics. The table on the next page gives suggested volume ranges for
each of the CTR models. Figures are for systems
without
the CLOAD
modification.
