Zx Microdrives files support (.mdr)

[PakkunKinoppi]

Hello, I am wondering if you could consider implementing Interface One as a selectable Add-on?

This ROM I meant: if1-2.rom - Interface 1 v2 ROM https://github.com/rastersoft/fbzx/blob/master/data/spectrum-roms/if1-2.rom

Thank you

Is this ask to use mdr (microdrive) image file ?

tape1.zip

Or anything else ?

Special basic add-on commands...

[Alvarez81]

A wedge-shaped device fitting underneath the ZX Spectrum, the ZX Interface 1 contained 8 kB of ROM comprising the control software for the Microdrives, an RS-232 port and network interface. This extended the error handler in the BASIC to allow extra keywords to be used

This is the first and the more used interface after kempston joy. Fuse has got it but how about RS232 support ?

[PakkunKinoppi]

Yes, ZX1 Interface adds some basic commands to load/save programs on microdrives (.mdr files). Thank you.

In preference panel a new selection path loader for locate and load the IF1-1.rom and IF1-2.rom as like as for zx48/128k would be better.

In any case, I thank you very much for this very useful and necessary enhancement to be able to recover many software from the web.

Great enhancement !!!

[Alvarez81]

Is there any way to convert .mdr files to .TAP or something usefull for ZxPoly ?

[Haroldo64]

@Alvarez81 ...keep calm, @raydac will support mdr files and some of ZX Interface 1.

BTW I think that RS232 support in not so important at this time for an emulator...
