Since you have freebanks, you could probably have both the Oric 1 and Oric Atmos versions of the ROM and allow the user to boot in Oric 1 or Oric Atmos mode, and have the games flagged as compatible with specific versions of the ROM, would make Atmos users allow to play Oric 1 games, and Oric 1 (or...

In my project, the RAM overlay is not available. I don't now how Sedoric works but if it is not writing in the RAM overlay for its management, I can store it in the bank 1 for example. The first CLOAD instruction will make appear the window to choose a TAP file or a disc. When a disc must be swapped...

Could you briefly explain how that works, does the device contain a patched ROM that takes over the CLOAD command and display the menu? Exactly :mrgreen: The internal ROM is always desactivated. The process is like this: In place of the internal ROM, there is a 64k UVPROM memory divided in four ban...

The ORIC computer is not modified.

Here is the final result...

The interface is complete.
Compatible with TAP files
Basic
Lm
Multiprograms combined.

The ula seems ok
The wire is not a converter, the video output is a rgb signal. The tv set might receive the rf signal only because the switch signal is not connected to a 12v psu.

Merci Chloé.

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 !
