R E M A R K S :   How to get a NEW RIBBON for this old machine ???
==================================================================
There are cartridges for MATRIX-Printers on the market with 8 mm
NYLON-Ribbons. Check the cartridge before buying because there are
several available with different lengths.  In some cases you can
get 3 spools out of one cartridge!  You will get your fingers
dirty when you do the respooling - but the result is great!
