<br>
I'm restoring a vintage synthesizer (a DK Synergy) which I had put into <br>
what I thought would be temporary hibernation, but turned into 20 years <br>
of storage.<br>
<br>
It mostly works, but testing suggests that at least one of the EPROMs <br>
has degraded and needs to be replaced. As long as I'm at it I'd like to <br>
replace all four (I'm told that I can use either 2765 UV erasable or <br>
2864 electrically erasable EPROM's)<br>
<br>
I have binary images (BIN files) for each of the EPROMs, but no way to <br>
program them.<br>
<br>
Can anyone on the list help? My only other thought is to seek out the <br>
various local "makerspaces".<br>
<br>
Thanks!<br>
Steve<br>
