Hi a few days ago a friend of mine dropped his non working commdore 128DCR to get some help fixing it.
The computer don't worked in 128 mode the keyboard typed random garbage.
So i replaced the ROM U34 for an eprom (128 basic) and socket both CIA's U4 and U1 replaced them.
This fixed the keyboard issues and the not working 128 mode and now the basic banner shows up in 128 mode.
The issue is that the banner "commodore basic v7 ...." shows but there's no ready prompt.
Read that this can be caused by a bad internal drive so found that cutting pin 1 from U113 disables it the internal drive have a broken head anyway.
Doing this don't changed anything still stuck after banner no ready prompt.
In 64 basic if i try to load from an external floppy drive tried device 8 and 9 nothing computer freezes and there's no activity on the drive.
Wondering what else could be ?.
