2 TOSs in one set of roms

[TheAtariKing]

One of my customers told me about his TOS roms in his Atari 1040STe. They are basically a set of roms that has both TOS 1.xx and 2.xx. There is an upper and lower area inside the roms and a switch is used to select which TOS is used. I would very much like to buy a set of these roms for my STe. Do any of you guys have any experience with these roms? How well do they work? I remember having a set of roms like this in my Atari 1040ST years ago. I could switch between TOS 1.0 and 1.4. Worked really well. The roms were the 6 chip type, not the 2 chip.

On STE you can switch only between 1.62 and 2.06 without extra logic.

Well, do you know where I can buy the roms already done?

I'm sure that there is people with EPROM programmers in US TOS ROM contents are available online, so all what need is to get chips and burn TOS in them.

You will need switch, some wire too for dual TOS

I can post chips too, but then count with not low shipping costs from Eu, plus need to use PayPal
