I have a early 80's KMB-1 , with a tape emulater, my problem is I could not get load master to come up on the crt screen, I replaced the mpu board board and that took care of that problem. Now I can not get the langauge screen to come up on the crt after loading the master. I replaced the reader board an put in a different tape emulater board, nothing helped.
any ideas?? thanks Charlie..
