CP/M filesystem

Post by JonB » 23 Feb 2015 23:04

Hi all

Quick question for you. What is the capability of the CP/M filesystem on REMemorizer? How many files, directories, users can it hold, and what's the macimum SD card size?

I know I shoukd know all this but I'm hoping someone can save me a trawl through the docs.

Cheers
JonB

From Memory, I'm ready to be corrected:

8 meg per partition, 8 partitions max.

512 files per partition.

CPM doesn't do Sub directories. it all on "root"

CP/M 2.2 doesn't do them, no. CP/M Plus (3) does, I believe.

You also get 16 user areas (0-15) which are sort of like directories. Sort of :)

Anyway, thanks for confirming that. I am about to see if I can transfer my CP/M setup from the TRS-80 Model 4 to the Memotech. 512 files sounds limiting in the context of 16 user areas, but we'll see. The TRS80 HDD interface I am using is quite a bit more limited. Anyway, I'm hoping for faster screen output on the MTX console (via REMemorizer's vga output)... And of course a good excuse to use the sleek alloy machine, with its lovely clicky keyboard.

To be honest, I don't know why I didn't try this before. The MTX has been looking pretty on the shelf, but otherwise gathering dust (yes, Dave I know, "shame on me"!). Time to apply some voltage methinks!
