TOS 2.06 for Mega ST 4

[macsonny]

Hi All,

 

I've bene trying to find the Lo and HI TOS images for the ENG version of TOS 2,.06, I just need the two ROM version. Know where I can download so I can burn with my EPROM programmer?

 

Thanks

I am not sure the Mega non STe already have the required address decoding for a 256KB TOS .... actually you may need specific decoding logic

Mega ST's - you can't just put in TOS 2.xx ROMS like for like without some extra jiggery pokery. There are some boards available from worldwide sellers to enable this for you.

So I know you wanted 2.06, but I can confirm this worked with EmuTos on my Mega ST

I can't say if it will work with 2.06 as I still think you'd need a decoder.  But if you're just looking for something better than TOS 1.02/1.04 EmuTos isn't a bad way to go.

EmuTOS exist as 192Kb and 256Kb. Some bits are missing in the smaller version. But excellent choice.

Usually the whole TOS version is downloaded and split as required on the Atari ST or ST emulator.

 

Loads of TOS images here:- https://avtandil.narod.ru/tose.html

As discussed previously, you will normally need a 192KB version for a MegaST.

 

Try the TOS1.04 without Line-F. It seems faster to me in an Atari STFM.

All seems a bit complex. Decided to burn the 6 ROM 1.04 TOS and a few mods to the board and all going great!

 

Thanks for everyone's advice.

I agree. It's probably not worth messing about. TOS 1.04 is probably the best Atari option for a Mega ST as they originally came with TOS 1.00. EmuTOS is more recent and still an option for you if you want to experiment.
