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.

Wonderful project ! It's a good way to democratize a handy transfer of our favorite games without complex process. Поздравления Iss !

...Kenneth show his SD card reader project (see http://forums.oric.org/t189-rs - in French)

I put an English-subtitles explanation here

...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?

It's more handy for updating, you don't need to erase the software with an UV lamp to re-write. I suppose that the EEPROM contains also the update microprogram.

I tried it, funny, and the background music is nice !
