Tatung: A history of a bad luck
April 2nd, 2013

About 3 months ago i have repaired my Tatung Einstein with stability problems, after a few minutes the screen was filled with random characters. Below the replacement parts:
- 2 x 74LS157 (IOO6/IOO7) Multiplexer.
On the same day has broken the Tatung TC-01 Monitor, the vertical sync is died without any way of adjustment. Yesterday, instead of celebrating Easter, i have tried to repair the monitor, the faulty component was as follows:
- 1 x TDA 2578A Sync Mixer.
Very happy i have connected the Tatung Einstein to the monitor, i have tried a few games and after 15 minutes the Tatung (computer) decided to die. I spent more hours to understand what could have happened, oh! found it, some ram burned. Below the replacement parts:
- 3 x RAM 4264 (IO11/IO10/IO8)
What could happen again?
I also did the dump of the eprom (rom), the download below.
