Hello Carlos,
want you to tell what I just learned:
your pictures show the 4 eproms where your sparc software is integrated
in every eprom 64kb means 256kb for whole sparc program. If you want to talk about RAM (work memory) Standard RAM of the Sparc is 1024kb. You can increase to 4MB. But then you have to open the module himself, because your pictures does not show this. As already mentioned in generell it is 1 MB if not increased before you bought it. But then I assume the seller has told you..because it is not that easy to increase the work memory. Hope that helps...
Kind regards
Tobias
