Interested people in controller Microdisc or AmpliBus.

This is the right place to discuss on how to implement hardware vsync, adding a VIA or AY chipset, puting multiple roms, or how to design a new flash expansion card.

Silicebit (the man who designed and built them) should answer this, but I'm afraid he only builds them in small batches. And the current one is complete.

Hi. Is it still possible to buy a disk controller for use with my HxC flashed Gotek and Oric-1?

Is it just a disk controller I need, or is there other hardware requirements?

Thanks

Check this thread http://forum.defence-force.org/viewtopic.php?f=9&t=1306

You need the controller and the amplibus (a smal card that is plugged in the expansion port).

Hehe, Silicebit's work is very professional indeed :)

Now be careful when connecting everything. Remember there is a jumper to power the Oric from the controller BUT if you do that DON'T plug the Oric's PSU!

That is, I think, the only probable way of damaging your Oric (though, sadly, it has happened).

Oh yeah, that's a really good advice, because it may fry the Oric AND the Microdisc, so.... :D

Thank you, iss. :-)

I'm happy to see that the parcel has arrived in good conditions. :-)

To power the system (Oric+controller), you have two options (well, really you have three):

1.- Unset the jumper 5V->33 and use independent PSU for Oric and controller.
2.- Set the jumper 5V->33 and use one PSU to power controller, and through controller, power the Oric too. As Chema said, not use the Oric PSU!!
3.- Set the jumper 5V->33 and use the Oric PSU to power the Oric, and through Oric, power the controller. This not recommended because you can overload the internal regulator of Oric.

Buf! Has anybody ever tried this? Anyway you still have to power the FDD with an external source, don't you?

In my experience the best and easiest solution is: use a external source to power the Floppy+Controller+Oric, set the jumper and put your Oric's PSU in a drawer to avoid any temptation :)

I am not a hardware guy, but having a good 5v power and avoiding the internal regulator, your Oric will be much cooler and happier :)
