I added a very early beta version of my gzip decompressor
to the web at http://www.cs.tut.fi/~albert/Dev/ -> gunzip.c64
You are welcome to try it. (A diskimage was decompressed
in 8:15 with a 1581, makes it 0.345kB/sec. But this is just
the first version.)
Current operation reads a named gzipped file from a named
drive and decompress the contents to another named drive (so
you can use two drives). If a file contains many concatenated
gzip-files, they are all decompressed.
All three deflate modes are supported: stored, fixed huffman and
dynamic huffman.
What it lacks is
1) 'proper' load and save routines
(even just changing from CHARIN/CHAROUT to serial bus routines
would probably help)
2) 'spiffy' user interface
3) most error checking (how do I check for "file not found" and
"file already exists" after OPEN? Do I absolutely need to open
a command channel for that?)
4) direct write mode for D64.gz -> disk
So, anyone interested in helping me in these?
