@stevja

Exxos has no more in his store, so you can burn them by yourself or ask somebody to do it for you.

You can find TOS images here:

You need an adapter or modification to make it work since there is no chip that you program that is plug'n'play for a 2-chip setup.

My chips are UK when I have them. I've never had a USA board to even salvage USA chips from.

You need DUALTOS board if 70789 type. Or convert to 6 chip tos. Or hack in EPROMS. All info is on my site.

I'd go for 6 chip upgrade, since a 2 chip will require a lot of hacking. 27C256 EPROMS are readily available and easily burned, and it just requires 4 sockets and caps to be installed.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Yes, dual TOSes.

I bought some from you.

I meant regional versions (one language only), like US, DE, UK, etc...

I sell 6 chip single language..

2 chip can't be done as no way to buy blank chips. So you either have to hack eproms like I show on my site, or use dualtos or convert to 6 chip.

Yes, but you also sell single language TOS 2.06 chips in your store.

And that was what I wanted to say after "My bad" statement:

"Exxos doesn't sell single language TOS 1.04 chips (x2 chips) other than UK version, but sells different single languages TOS 2.06 chips (x2)."

to be precise...

Hope I'm understood now.
