Hello.
Under the eeprom socket two diodes and a 10K resistor are required.
But this image should help you.
Taken from version d2 in velesoft web page:
These versions d2,d3...d4 are special for brazilian clones TKs, for +2a works with less components.
(please resize the caption) this message board do not fit the images.
With the info taken from version d2 and laters...
For the spectrum +2A/B +3 the config of some jumpers:
CLOSE JP1
CLOSE JP2 FOR ENABLE FLASH FIRMW IN EPROM
CLOSE JP3 this are only for +2A/B +3
if you use +3e ROMS in the +2A/B +3 ...CLOSE JP4 & JP6
if not leave OPEN.
For +2A/B +3 only:
don't solder D5(1N4148),D6(1N4148), R16(220R)
(please fit to page) or "save img as"
...version d4 are UNTESTED by the autor.
Hope you find this info usefull.
You do not get offended, because it is difficult to express myself in a language that I do not master to perfection.
The author of the page is a very friendly and helpful person, write directly to him, who will be able to help him for sure.
He has helped me with many doubts, I have always managed to fix the problems I had writing to him.
regards
Julio.
