Developed to give constant-speed amateur radioteletype transmissions despite erratic keyboarding speeds Uses NE555 timer chip as free-running MVBR whose speed can be varied by R1 down to about 1 character every 15 s or up to full machine speed. Can be used with any automatic send-receive machine. Keep enough slack in punched paper tape to permit backspacing and correcting errors before they are sent. With 5-V supply shown, 6-V SPST DC relay can be used.-B. Gulledge, Mechanical RITY Buffer, 73 Magazine.Oct.1976, p 74.
