Re: STE Dual TOS switcher widget

Main problem with the first one is that the peg for mounting the floppy is right besides the header. And mounting it using a female header on the header-board, below the dualTOS, won’t work since it’ll hit the motherboard. At least I think came to that conclusion when I looked into it. It does actu...

Re: Alt-/Fast-/TT-RAM expansion for 1040STE
