Good

Oric computer drive directly the sdcard via CS MISO and MOSI sdcard signals without PIC or Arduino systems. With the 44ko of memory remaining in the uvprom interface it could be possible to create a platform like Microdisc or other.

My interface is now able to load a one piece program. I m working actually for a multipart loading. This could be available for protected games.

Takk for arbeidet.
Vi må feire med Akevitt!

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...

The power voltage is too low. A chip swallows too much energy. Maybe a DRAM memory is dead? This one is hotter than all others.

Nice !

Je teste actuellement une lecture du répertoire racine d'une carte SD avec des portes logiques et un EPROM 64k. Le projet n'est pas terminé...

You should erase your email name in this thread, otherwise naughty robots will disturb you...

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...

nice project
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).

Merry Christmas and good projects for Oric

I think that there is no power enought on the printer port and IJK-PASE interfaces are not compatible.

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