Re: This is crazy - Double Disk drive for £445
I have the exactly the same items in perfect condition (would never sell or use them). Seems like they are becoming more valuable than gold dust! ![Surprised :o](./images/smilies/icon_e_surprised.gif)

Anyway, I've pushed up a snapshot here: http://www.6809.org.uk/tmp/xroar/ which will load d200e_1.rom, d200e_2.rom ...

Oh!!! It's this: 1030 DATA 1F,A9 ' TFR CC, B 1040 DATA FD,45,00 ' STD $4500 ; STORE A+B :o Comments not striped in DATA ??? Boring :x The only way to add comments is to add an extra REM line after each data line. 1030 DATA 1F,A9 1031 ' TFR CC,B 1040 DATA FD,45,00 1041 ' STD $4500 ; STORE A+B
