Re: TOS upgrade for 1040STF
Wow! TOS chips received in only four days from UK to Spain :shock: Are you sure that UK not stills being into the EU ? :D It has been easy, just to release the two original chips, set the three jumpers to 256K and install the six chips in its sockets. It works like a charm. 0EyVvxn.jpg Rpqb1YE.jpg

Re: TOS upgrade for 1040STF
If you 'downgrade' to 6 chips, the machine will run just fine with no power problems. Aside from soldering in the sockets, there are pads near the ROMs marked 1M or 256K, or very similar.

Greetings from Catalonia
Hi there,
I'm a retrocomputers collector and the last "pet" I get was an Atari 1040 STF, that's why I joined this forum.
Cheers.
