Yes they are. See the project's repository at sourceforge, under files/cartridge and files/adapter.

[...] I would not recommend anything requiring LOAD, POKE, or attaching a VIC rom to start your journey.

I tried Minimon, which when attached as a BIN file, just crashes the VIC when invoked [...] The *.bin file of MINIMON does not feature a load address, it is explicitly intended to be burned on EPROM using a PC.

What you dismiss here as "cryptic" or "insulting" answers are answers that tell you to do your homework first. To make things clear: drive code is notoriously difficult to debug. One single programming error, and the drive will simply stop responding, leaving no clue to the progr...

It just happened again. Just a program, nothing special, with a blurred end after the listing. You still remain short of providing a reproducible test case, where a program is corrupted without the known usual suspects as cause (i.e. stray POKEs into zeropage or into the tokenized BASIC program tex...

I am no farther along than where I was last week. Sometimes the color map is right, sometimes the bitmap, but never both at the same time. If you proceed by first loading the original picture file to $1001 - as I laid out in my preceding post - you need to: write the colour RAM from the data locate...

• [...] Warns before attempting to copy USR files for example.

Normal files with USR type, as an 'alternative' to SEQ type files, or actual drive utility files (loaded by CBM DOS directly into drive RAM and executed there) should not pose any problems. You are concerned about GEOS VLIR files?

ral-clan wrote:So what does File Conductor do?

File management on the native platform: here, with a VIC-20 and (preferably two) disc drive(s). Copying files between disks, renaming files, deleting files, sorting the directory, you name it.

See another thread for bjonte's motivation to do his own implementation.

FRESSMANN (it's contained in my Unexpanded Games Collection, see the screenshot further down the thread) uses quite the same idea.

May I suggest you use MG BROWSE to view the instructions? I find the built-in lowercase character set rather difficult to read due to its flattened appearance and lack of line spacing, and those 22 columns/line lead to lots of premature line breaks. MG BROWSE displays any 7-bit ASCII text (which cov...
