Bootable disk for Telestrat under Euphoric?

This is the best place to discuss about the various Oric operating systems like Sedoric, Randos, FT-Dos, and others.

That won't do for me for I have a LOT of files that the program itself loads and (c)saves... If I put them all in one DSK file then in a period of time this could lead to some heavy fragmentation of the DSK file, I could "run out of free space" on the DSK file(s) and so on.. Not to mention that I would have to (at least) change the CSAVE, CLOAD, RECALL and STORE routines in ALL the TAP files before I convert them to DSK...

One of the reasons why I am interested in the Telestrat configuration is that Telestrat have the time counter.
Consider this program; it is an "RealTimeClock" from the Geoff Phillips's book "Oric Atmos and the Oric1".
When loaded on the ATMOS configuration, and left for about 8 hours, it will cause an error in time in about 40 minutes!!! That is a lot! :(

On the other hand, consider another program;
When loaded on the Telestrat and left running for about 8 hours, it will cause an error in time in about 8 seconds!!! That is acceptable!

What I need actually is the Oric-alike configuration (preferably just the Atmos) but with the real-time-clock utility available for long periods of time with the "time-error" reduced to minimum as possible...

At this moment I am not sure of what CAN I do...

If You are interested, you can use TXT2BAS.EXE to convert these two programs (or at least the first one - the first one is rather "hard" for typing) and test it yourself to "see what I mean"...



"RealTimeClock for ATMOS:"
(This one causes an error of 40 minutes in 8 hours!)
P.S. Before execution - turn ON the "RealTimeClock" variable in Euphoric's INI file.

wow !!! Bravo !!!
It is reallly a nice beginning in Telestrat programming.

You could ha spare some effort with a loop and the DATA statement anyway, but reallly, for a beginning, it is really nice !

Not sure if using the page 4 on the telestrat is safe.
And modern code for tools/applications/utilities should NEVER use the page 4, because it makes sure it's not possible to use a disc drive (the DOS generally put code here).

That's fine for games and demos if they don't plan to go back to the system later.

I suppose there is no web-server from which I could download any of the books regarding the learning of the machine-code programming that I have found (only presented) here:
