Re: Master 512 & Winchester disc 130...

Superform is BASIC, do *BASIC first then CHAIN"Superform".

The disc error 1C from the Kyocera drive is a good sign, it means it is recognised but not formatted. Superform will format it. You need to set it as 615 cylinders with 4 heads.

Re: Playing with OSWORD &A

Not as much fun, but you can use VDU 23,16 on a Master to alter the vertical and horizontal direction of text (and some other effects), eg. VDU 23,16,6| will move backwards and up instead of forwards and down.

Re: How Many Directory Levels Can the RISC OS Desktop Filer Show?

Interesting discussion...although in fairness I don't think 22 levels is asking for trouble. If you think about how the L4 file server creates additional directories, it needs 4 extra levels for a full Econet 254/255 entry directory. 22/4 = 5 and a bit, so it doesn't seem unreasonable that a network...

This is on my RPC 700, with RISC OS 3.70. It's just done a week's work as an L4 file server storing all the data from my CF card based L3 file server.

Re: Master 512 & Winchester disc 130...

Good work..that adds up to about 4MB, so it is correctly reporting the space on your new partition. As the previous one has been renamed, it isn't seen by DOS Plus any more. If you want to change back to that you would have to rename that back to DRIVE_C and rename the current one something else.

But remember if you are using Acorn DFS there is no difference to capacity or disc format between the 8271 controller and the 1770 controller - you still get 200K per side on an 80-track DFS disc. All this business of "interleaved" disc images (.dsd for DFS and .adl for ADFS) has really muddied the ...
