Documenting the Tiki 100 400k format

[tingox]

Tiki 100 was a Norwegian computer running Tiko, a CP/M 2.2 compatible operating system. It used 5.25 inch floppies, 40 track or (later 80 track). This is a dump of a 40 track floppy, read on a 80 track drive, using the following command:

tingo@z30b:~/personal/projects/psoc/fluxengine/tmp_tiki$ ../fluxengine read ibm -o 525-tiki_100_400k_tiko_4.01_tikos_2.00_25.img -f 525-tiki_100_400k_tiko_4.01_tikos_2.00_25.flux

As far as I know, there is nothing confidential on this image. Using the correct definition in diskdefs (cpmtools), cpmls can read the directory:

tingo@z30b:~/personal/projects/psoc/fluxengine/tmp_tiki$ cpmls -f tik3 -l 525-tiki_100_400k_tiko_4.01_tikos_2.00_25.img

Very very belatedly... I have just added profiles for the four Tiki formats (called tiki90, tiki200, tiki400 and tiki800). I've tested the CP/M filesystem support for the 200kB and 400kB formats and just kinda guessed for the other two --- if you're still interested in this, let me know if they work? Thanks very much!

They're currently read-only. They can be made read-write but that'll need a real machine to test the written disks with.
