My new Cumana drive ;)

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.

Just a question: will it possible to upgrade the FF firmware on your board (or even change it to HxC) ?

Is not to late, i have 30 PCB so soon will be more for sale but i need do this first 10 for people who trust and preorder it. I hope relist next 10 on end of next week.

About second 3,5 drive, i plan do separate unit, also in this case. Will be not really expensive.
Good news, thanks!

I've been fantasising of modelling an expansion bay style enclosure that can accommodate the Atmos/Oric by just sliding it on to the base, so there'd be a box under the Oric for the PCB's and relevant ports for USB receptacles, etc. I'm kind of fatigued by the cable mess of my Oric setup and would love to just have an all-in-one situation like exists with my CPC and ZX setup (Amstrad versions).

Seems like with those dimensions it'd be feasible .. time to fire up the OpenSCAD and get some mockups done ..

It is, FF is installed by default,so update is easy from pendrive.

On board is socket for programer, so you can reflash it for HXC but i not see any reason for use HXC firmware and you do it on own risk, i cannot guarantee proper work becouse i was not test it on HXC. I'm in good contact with Keir (author FF firmware) so is easier for me ask Keir about any firmware updates .

Second 3,5 floppy unit idea...

Thank you for your answer.

I also prefer FF as .dsk file format is directly supported, and if firmware upgrade is possible, I will then upgarde to FF 2.14 or even to 3.11a...

BTW, your 3.5" FDD idea seems promising.

Cheers.

Funny, I had that in mind exactly - two drives side by side under the Oric. But thought maybe having the Oric above the drive system might not be safe for the drive, or whatever.
Let us know how you carry on with the idea ;)

Wouldn't it be a hassle to use the Oric then ?

Just imagine typing something with the keyboard about 5 cm above the desk...

I don't know, but I can imagine a pain in the wrists just after a nice party of Cosmos 1999...

I personally like the way our friend Zaxon made it... Just near the Oric.

:D

Doesn't have to be below the Oric - could also be behind it, as in a box which extends the length of the Oric, not the height or width .. anyway, will play with some ideas ..

Hmm, it is my DDI3 for amstrad CPC,(similiar unit like CUMANA , floppy emulator and floppy interface) connected direct to CPC expansion port. I can redraw CUMANA board and shrink it for this style, but i think, 34 pin connector is to weak to hold it in place. Maybe if i use rerial port too ? Only for hold interface.. ??

It's a parallel interface, not serial :)

That being said, if you do a pass-through printer connector, you could also extend the interface board to put some joystick connectors, since this port is often used for that.

Ok, my fault, paraller , serial .. bzzzz ;) Idea anyway is canceled due to Oric case design ;)

"That being said, if you do a pass-through printer connector, you could also extend the interface board to put some joystick connectors, since this port is often used for that. "

You mean connect it flat, behind Oric ? Like in ZX Spectrum ? This can will be oend like this ;) I try do my best for prevent it ;)

Our beloved Orics would become "La Oruga Infernal"... (ie. The Infernal Caterpillar)
