If you want to ask questions about how the machine works, peculiar details, the differences between models, here it is !
How to program the oric hardware (VIA, FDC, ...) is also welcome.

The chip is a 27128 UVPROM with a 16k memory, in this case the Erebus don't work, you must burn an other UVPROM with a ROMDIS pin compatible.
Alright, now it is clear, thanks for reply. Will try to burn another sort of ROM chip then!
Alright, found this thread, looks a bit complicated. https://forum.defence-force.org/viewtop ... 0&start=15
Could you specify in this case a commonly used (it not rares) ROM chip that will be good? Even better, few ones. I will try to hook them.
Apart from 27128 UVPROM
So instead of getting new ROM chip the solution may be to simply remove the current ROM.
As Erebus still may work (it has its own ROM) it may be a temporarily workaround until the new chip is burned.
