HxC SD floppy emulator works with X68000 CompactXVI

Re: HxC SD floppy emulator works with X68000 CompactXVI
No. Have a look to the picture more carefully, there is no point with the actual version of the HxC. This is an FPGA version.caius wrote: Sorry, but is this standalone version the SD version we already know.WHich is the news regarding X68000 emulation?
Re: HxC SD floppy emulator works with X68000 CompactXVI
Ah, yes, pardon, now I can see the FPGA solution.When do you think it wil be released?X68000 FD emulation will be implemented as well?Jeff wrote:No. Have a look to the picture more carefully, there is no point with the actual version of the HxC.

P.P.
In my CompactXVI I adopted the kitahei88 solution and it works quite well.

march 2015 i think.

Re: HxC SD floppy emulator works with X68000 CompactXVI
One question to the X68000 users :
Is all software/games 100% compatible/able to work on externals drives, or is there some of them "hardcoded" to work only with the internals drives ?

Re: HxC SD floppy emulator works with X68000 CompactXVI
Hi Jeff.If external floppy drives are set as '0-1', I'd say there are no problems.If they are set as '2-3' I think some of them will not work since game code will requires them set as '0-1'.Besides, as far as I know, external drives set as -2-3' cannot make boot. Are you working on a X68000 solution?I remember you told me about a new HxC floppy emulator FPGA based with full X68000 support.Jeff wrote:One question to the X68000 users :

P.S.
This is an external floppy drives for CompactVXI model, as you can see it has on the back a switch to set drives as '0-1' or '2-3':

Ok. All X68000 have these switches ? These switches also change the internal drives settings ?caius wrote: P.S.

Yes. About the FPGA, i am afraid that the final price tag will be far to high for this... For the moment it's 150/200euros the emulator. We have to face it : this is not reasonable for the retro-computing/gaming market. Sure I am still working on the next generation HxC Floppy Emulator, but for sure its target will be more professionals and industrials users due to its price.caius wrote: Are you working on a X68000 solution?I remember you told me about a new HxC floppy emulator FPGA based with full X68000 support.
The actual retro-gaming price tag for a floppy emulator is between 30-50Euros, so this rule out any specific design based on FPGA.
So i think that the small and simple external floppy adaptor board for 10/20 euros with some glue logic and/or a low cost/tech MCU to mimic these signals is a far better idea. And this will allows anyone to use any HxC / Gotek / Floppy emulator / PC Floppy disk drive on the X68000.
Re: HxC SD floppy emulator works with X68000 CompactXVI
No, only the Compact model have this switch.Infact if you will look at the pinout of X68000 Compact internal FDD you will find a "EXCHANGE" signal which I believe it must be asserted to set internal drives as '2-3' and external ones as '0-1':Jeff wrote:

This is external pinout of all X68000 machines:
http://www.gamesx.com/wiki/doku.php?id= ... ppy_pinout
I'm pretty sure X68000 can't boot from external FDDs set as '2-3'

You are the engineer/developer so it's up to you to choose the market targeting.A simple external board will be fine but, as I told, we have to verify it X68000 can use external FDDs to boot from.I remember that when I used external FFDs on my X6800 machines I had to use a software that install some driver on SRAM to allow booting.Anyway, if you need testing, I'm here at your disposal.
I suggest you to jon us on NFG forum, there a lot if expert people there.

There is already many quite expensive FPGA based (or not) since years, but they have all fail into the "old computing" market for many reasons, but the first one is the price.
Have a look the HxC Floppy Emulator blog : http://torlus.com/floppy/ ( 05/04/2007 )
The first versions was based on FPGA. I have to change this to a MCU solution cause of the price. But for sure FPGA solutions are technically far better than any MCU / software solutions.
And anyway, no, generally the engineer/developer don't choose the market. Someone tell him which price this should cost
And most of time this is the "lowest price solution possible".
Ok. So for sure the pcb will be as small as possible to allow internal use too.caius wrote: A simple external board will be fine but, as I told, we have to verify it X68000 can use external FDDs to boot from.I remember that when I used external FFDs on my X6800 machines I had to use a software that install some driver on SRAM to allow booting.Anyway, if you need testing, I'm here at your disposal.

Re: HxC SD floppy emulator works with X68000 CompactXVI
That's good, each team member has his task so the engineer has more time to work on the hardware (which this is the important thing.Marketing, advertising, etc are secondary..)Jeff wrote:

OK,I forgot to say that internal and external FDD connector signals are shared, pins are in continuity (maybe except for the PRO model which use FDDs with a small connector apart for the proprietary signals)Ok. So for sure the pcb will be as small as possible to allow internal use too.

Good job, my dear engineer.Jeff wrote:First schematic version of the PC Drive / Floppy Emulator adapter for the X68000 :
So, this adapter is going to work both with a real PC FDD and HxC emulator?
Have you done only software simulation or tested the circuit on real hardware?
Is the PIC code available?I'd want to try the circuit and report feedback.

Yes that's the idea.caius wrote:So, this adapter is going to work both with a real PC FDD and HxC emulator?

OK.I see you emulated all the extra X68000 signal and not only the most important (INT and DISK IN).Like other solutions also the yours will requires to activate a switch to notify the insertion/eject of a disk/disk image.
OK, Jeff, I wish you a good work and keep us updated.I'm always here if you need deep testing.I am writing the software, so schematic change still possible
