IDD CI24 ECONO MM Penta 1.20 Galaxy II 1.2Mtr Polar MTG yes it has been on the arc for 25 years and is now fixed on 13 East using two pairs of rusty molegrips. Unlike me they never groan but always perform.
Yes you seem to have a problem there, the main website does not seem to have a link to the firmware in this instance. Have you had a look in the Portuguese forum as there are some links in there or if you speak the language then you may be able to nake some contacts who can advise you. As you have not filled in any detail I do not know where you are from
I also notice that there is a registration facility and you may have to register to get the firmware click here
