Happy birthday, Oric !

This animation program uses Plethoric, a code that uses a (little) different way of drawing than the Bresenham's algorithm. :wink:

Re: Tapes not loading

You can try some mp3 files from TAP files with a digital player to diagnose your audio wire.

Re: Erebus.

The power supply must be able to provide at least 1A.

Re: Erebus.

Hello
Try it with an LM7905 regulator.
What are the characteristics of your power supply unit ?

Re: Erebus.

For the checking, the RomBasic chip inside the Oric computer can be removed while using the Erebus interface.

Re: Erebus.

There are two possibilities:

1: The assembly needs a 900mA power supply, the switching regulator may be too light.
2: The Oric uses a 27C128 UVPROM instead of the original ROM, the ROMDIS pin is not functional. Some UVPROM chips are compatible.

Re: Oric Atmos to bring back to life!

You can program EEPROM memories, they can be erased with the memory programmer, but UVPROM memories (with the window on the box) cannot be erased electrically, they must be illuminated for 20 minutes with a special uv tube to erase the chips , then the memory programmer will check if the memory is e...

https://i.servimg.com/u/f34/16/12/43/32/dsc_0011.jpg The black connector on the left could be ideally used for this, with a shielded cable, it contains a 20pin Dupond header. It was used for the AMX mouse with the CPC computer. The shell is very difficult to find, maybe a 3d printer can solve this ...

Re: Cable LORITEL

The cable is not grided, then I supose that the choice of d7 is a way to "separate at the farest" tx and rx to avoid radio disturbance. Beware with this adaptator: the rs232 protocol is using normally -12v +12v, this one is only compatible with the Minitel device, using a TTL level. The 65...

Re: Oric Nova 64 display issue.

The diagnostic cartidge can detect something wrong when reading the internal architecture by the expansion bus...but the rvb output is not reachable by the tool, this is the only failure undetectable.
