I searched many article this forum,I type hgr from apple II clone.and show this screen,I wonder if certain ic ram problem?I consider this ram need to prepair.because this is my first time to fix this machine.so I hope can get your suggstion.thx
The graphics part of the display output (the upper 9/10 th's) looks correct. The HGR command displays a mix of graphics with text at the bottom of the screen. The graphics part has been correctly cleared (by the HGR command) to display all black, the text part should also be blank except for a flashing cursor if you are in command mode. So some thing appears to be wrong with the text buffer in memory maybe? Good luck with your diagnosis and repairs (if needed).
