Almost! +5V to EA will simply disable the internal ROM, it won't put the chip into programming/verify mode. For that you'll need to supply EA with anything from +7V to +23V, depending on the part. Word is +23V is for EPROM parts, +7V to +10V for mask (which these are).
It looks from the schematic that you have /RESET tied to +5V at all times. Meanwhile the instructions I have for the I8741 (a similar/equivalent chip) say to power it up with /RESET at 0V.

Alright, will do. I've also sent an irate PM to the dev who posted his dumping script to a site that apparently fucking expires posts within 48 hours, asking him to repost it on a better site... :|
