Keyboard replacement
Just received a TI-58, made in 1978 Holland, to be used as spares for this TI-59. The keyboard needs to be removed on both machines, using a good soldering gun and some caution to not destroy the PCB. It turns out that the PCB quality is first rate on both machines, resisting to a lot of abuse without apparent damage. TI-59 PCB with the keyboard removed. 14 empty holes waiting for the replacement keyboard. ![]() The original TI-59 keyboard (from 1982) taken apart and cleaned. I believe I can repair this keyboard as well. Well, I will have a try one of these days. IMHO the bouncing issue with these keyboards are related to the fact that some of the dome's crimping connections are getting lose with the usage. ![]() ![]() The keyboard replacement. Despite being an older unit (1978), it works flawlessly. ![]() ![]() Jose Mesquita RadioMuseum.org member |
