Dumping 8" diskettes.

I looked at the "OSI Disk Dump Tools" on the site and they seem to be for a basic ROM machine not one with the
sysmon ROM. A quick review of the assembler code I noticed a few things addresses are different than
the ROM in my machine.
Does anyone know if there is a disk dump routine that works with OS65D for a 8" floppy on a SYSMON based machine??

See latest tools in winOSI 1.5 download. Supports serial and video systems and x modem dumps.

You may have to change the ACIA address but if I remember correctly it does a machine detect. What addresses are you seeing different ?

While looking for the WinOSI software I noticed a C3dump program.

That is exactly what I need.
As for the OSItools, I noticed in the RAWDUMP.ASM program the get/put char address were different than
my ROM routines
Code: Select all
;OSI MONITOR ROM ROUTINES
INPUT = $FFEB ; GET CHAR FROM KEYBOARD/ACIA
OUTPUT = $FFEE ; PUT CHAR TO SCREEN/ACIA
On my system the get/put routine are at inchar = $FE00 and outchar = $FE0B.
I assume the RAWDUMP is for a system with a different ROM. I could start hacking but right
now I'm more interested in getting the floppies imaged. Most of them date to the early 1980s and
are some are acting a bit wobbly.

There you go. I had noticed C3Dump but did not appreciate its so different from RawDump.
I did create a SYNMON type serial ROM and try on my 502 using ACIA @F000 some time back. Had limited success with tape I/O but the intention was to get a better idea of these systems. Nothing like having a real C3
Good luck.
