[net.micro] more on TTX keyboard

knudsen@ihnss.UUCP (02/02/84)

I forgot to mention the clincher:  On ADM's, HP's, etc., you can pull the
keytops off malfunctioning keyswitches and spray the contacts with
TV tunner cleaner, which makes things nice for another couple of monnths.
The TTX keyswitches cannot be fixed; the buttonns pull off, but the mechannism
unndernneath is sealed, annd soldered to a PC board unnder the metal moutninng
plate.  (Yes, it is ruggedly built.  A tank with an X-car enngine).
	Does anyone have solutions to such problems?  Are other cheap
terminals suffering from such keyboards?  Do VIC-20s have better keyswitches,
or does their firmware just scan too slowly to catch the bounces?  mike k
Againn, just my personal experiences, not AT&T views.
