Re: Oricutron 1.0 (EDIT: Now 1.2)

In my humble opinion, the current status of Oricutron's sources is quite stable and there is no critical issues reported. That being said I think it's really time for new release. I'm ready to help where is needed! BTW, I will be very happy if before release all sources are passed trough a code form...

Re: OricExos - making the impossible

Re-captured and merged previous "color bars" and "more color bars" demos.


@ibisum: I think it's possible to use more Oric's to "retouché" old games but it will be not easy task.

Re: OricExos - making the impossible

Here are some dimensions of 4 Oric stacked: dimensions.jpg I agree with Chema - there is no need to cut Pravetz - you can use its keyboard with long ribbon cable (mine works fine with 1 meter cable).

Re: C/ASM profiling tools?

Just small addition for Oricutron's internal cycle counter - you can control it with breakpoints too.
For more info see my post here and the ReadMe.txt.

Re: OricExos - making the impossible

Two questions for you: - Have you found a solution to enable the overlay ram on all three slave machines? - Is the communication only master->slave The communication is only one-way (i.e. master->slave) else I have solution for both your questions. For best results I will order real PCBs which will...

Re: OricExos - making the impossible

Yes, there are so many possibilities and some of them are really hard to imagine. Now I want to share that I just succeeded to fix the 4-th Oric! The problem was very annoying: it refuses to CLOAD anything with the patched UV-EPROM but it works just fine with the original v.1.1 PROM ?!? :shock: Afte...

Re: OricExos - making the impossible

Just small update with some color improvement...
2018-10-24_00-33-50.jpg
This is output from 3 Orics (the already posted "bars demo") but now with 3 trimmers to adjust RGB levels.
More news are coming ... (hopefully soon).
