Hi All
Do anyone know of a way to have switching system from a real floppy drive to the HCX floppy emulator drive on the internal port of the a1200 system,

what I mean is my current configure is df0 is a really drive and df1 on the same internal port is my HCX floppy emulator which work well, but how ever if I want to play floppy games then the HCX floppy emulator needs to be df0 not df1 as most games only work off df0

so is there a way to make a switch which I can switch between a real floppy drive and the HCX floppy emulator as df0 and hook a switch on the front of my tower case to switch between the 2 drives?

anyone?

Why not disconnect df0: what drive does that assign to the HXC? If you still want a real Amiga drive, use an external. On PCs the 2 head floppy cable had some crossover to determine which drive was which. Don't know if that works with Amiga's floppy interface.

I would have thought this was a lot of work, but apparently the A500 and the A2000 is wired the same way, so both SEL0 and SEL1 are on the internal 34 pin connector. Use a DPDT switch to select straight or swapped select pins, just follow this (but use a smaller DPDT):

Then you obviously need to wire pin 10 pin 10 on one drive and pin 12 to pin 10 on the other. Possibly a crossed PC floppy cable will work, but I'm not 100% sure.

If your Amiga drive has a DS or SEL jumper, this can be used instead of crossing the wires in the previous paragraph.

@olegil

thanks for the feedback but I am not sure if you understand me

what I am going to do is a pcb for my hcx floppy drive and my real drive to switch between them as df0 only not df1

Why on earth would you NOT want to have a df1 using the other drive? Considering the cost difference between a SPDT and a DPDT switch is literally sweet fanny adams.

@olegil

as because there is no MTR line on the internal port for df1 only df0 which means the motor on the df1 drive will not spin that is why

But an A2000 supports two floppies and I can only find one MTR signal on the 34 pin connector there as well.

@amigat

Can you configure it so that HCX is on DF0 and actual drive is on DF1? If that at all helped.

@amigat

Have you tried booting from df1 using the early start-up menu?

@amigat

Solution to your problem is probably these two devices here:

http://amigastore.eu/en/485-df0-selector.html

http://amigastore.eu/en/439-amiga-external-floppy-disk-drive-adapter-m2.html

Hope this helps.

Yeah, that seems about right for what he insists he wants (except I would still like to say that it would make more sense to SWAP them, so both are available in both settings, not just one at a time).

well I am going to try and build a test board first who know if it works some of you mite want it

Buying an experimental board from you versus buying a finished product from Amigakit if it's gonna do EXACTLY the same thing? Don't bet on it. Unless you actually want to make it BETTER by incorporating my suggestions, don't bother. Spend your money and time on something more worth while
