Re: Mistakes in books: l'Oric à Nu

Hello, A couple of other mistakes I noted regarding tape I/O : (these comments ONLY apply to ROM 1.1, I've never used routines from ROM 1.0 / Oric 1): * p.59: oversight for flags at $25A and 25B (missing values): - $25A (tape merge flag): I don't know the values, sorry... - $25B (tape load/verify f...

Re: VIA "networking"

The VIA chip is very useful in many protocols in the serial mode, but the used channels are CB1 CB2, unavailable on the printer port, in spite of this, we can connect all Orics on the parralel bus, and connect a little EPROM interface on the expansion port like Fabrice-F PCB with an 'almost' same BA...

Re: ORIC SDCARD

nice project :D
The +5v is also available on the main power socket of the Oric computer.
The relative voltage from the Oric ground is -4v and +5v (negative regulator).

Maybe that could be done for the Oric computer and the Atmostrat project.

...Also ,somebody know why in Cumulus is Flash EEprom 256, not normal eprom like 27c64 ? Rom for microdisc is 8 KB. So what about rest?
