Need help with Sharp MZ80K repairs
Hey there!
I got a Sharp MZ80K a while back, but it shows only random characters on screen when turned on instead of the console.
I cleaned it all up and measured through all the pins on the ICs looking for cold solder joints, but it's all good. I got some a _little_ bit off wave forms on the osci for some ICs but am still not entirely sure what's going on there. Really hard to find anything about this machine apart from the manual. :/
If someone has this machine, too or could connect me to someone who could help me out with this, I'd deeply appreciate it!!
Thanks so much!
