1. Beta Disk Interface - Need System Disk

I need the System Disk for the Beta Disk Interface (ZX Spectrum) on 5.25" floppy. I am willing to pay copying and shipping costs for this.
Thanks, Jack

AFAIK there's no system disk, you just need a blank one.
You can format one by connecting the 5.25" to a PC and using some
TR-DOS support software or emulator (AFAIR the RealSpectrum should do).
The software may require MS-DOS/Win95/Win98 to work properly with floppy.

As far as I know there is no system disk. The manual certainly doesn't refer to one and the OS (TR-DOS) is normally held in ROM. If you've got a modified unit that loads the OS from disk you could probably get it working by putting a ROM back in it. Images of the TR-DOS ROM are widely available. These links may be of some use:

AFAIK there's no system disk, you just need a blank one. You can
format a disk by connecting the 5.25" to a PC and using some TR-DOS
support software or emulator (AFAIR the RealSpectrum should do).
The software may require MS-DOS/Win95/Win98 to work properly with
floppy.
Disk format is similar to Timex FDD 3000, but uses sectors 1..16,
not 0..15.
