WY-30 10 duds Wyse terminals update:

Got one fixed, reset was held low because of bad soldering in the reset circuit. And I determined I might have 4 or five possible working units out of 10. 2 had total PSU, fly and HOT failure, and another two have HV stink. Note: I had diffcult time finding 6800 (68B00 same CPU but it's 2MHz) datasheet. Still couldn't find it except for pinout which helped me to figure out that one terminal. Is there any reliablity fixes or bulletins that I should know about while I fix these? Because some of them did not have this fix like this one i fixed has many diodes tacked to the pins of the IC and all of them did not have correct wire grounding strap that goes around the CRT bell (the current configuration is relied on the pressure of the steel wires (this makes up part of the cage) against the CRT's bell, I don't like this). How is the reset circuit is done in this as well? Finally, last question, how stready is the PSU pulses? Some of them is jittering in PWM where good one is steady. Cheers, Wizard
