I just replaced a bad chip on my 128DCR motherboard to get my internal 1571 working again, so I thought I'd load a few programs and format a disk or two to make sure my fix was successful. Here is the result: Post on C128.com I'm cross-posting here in case someone has any suggestions on what I need to do to fix this. For some reason, this forum won't allow PhotoBucket embeds, so follow the link for the photos I took to document the issue.
I'am a proud owner of a C128 DCR for a few days now, and i have a strange drive problem i think.
When in C64 mode i tested it like this: open 15,8,15,"u0>m1":close15 load"$",8 list the list show the correct free bytes, both the floppy sides are visible.
And i can format a floppy with: open15,8,15,"n0:dsk,10":close15
Formatting the disk is fast, and correct free bytes shown after that. I can save, load, etc all works.
In c128 mode, when i insert the disk, and type "directory", nothing happens, the prompt just shows "ready"
If i try to "header", or format with open15,8... the drive and c128 locks
When I try to list the disk content with load"$",8 than the prompt shows "File not found" error.
So everything works as it should in C64 mode, but nothing in C128 mode. Is the drive using other roms for the two mode, or whats the problem here? C128 basic rom, kernal rom? How to test, or debug it? Unfortunately i can't swap roms because i just have one 128.
