If it's a bit on I have an Advantech LabTool 48UXP, which has exactly that - Vcc adjustable between 2.0 and 6.5V - in what increments, I haven't really tested, but at least 0.25V maybe even smaller. Though this sounds like a problem with the support circuitry around the EPROM array, and not a data integrity issue within the array itself. Something like a blown sense amplifier or a shorted output buffer / pad driver. Somehow I'm inclined to think it's the latter, in which case there's little anyone can do to save the data without physically cracking open the EPROM case and sticking a test probe on the bare die. And even then... Sam Message was sent through the cbm-hackers mailing list
