Sinjinhawke Posted December 22, 2021 Share Posted December 22, 2021 That looks like my 130xe. One NEC ram chip and the rest mT ram. I replaced all the mT in the first row. Left the 2nd row for now as it seems to pass extended memory tests and my equipment for desoldering is not great so it’s quite the chore.
