From: ramswell on 26 May 2010 16:56 Can anyone out there make a copy of the Fotios FB512J Eprom? I tried and I tried to copy the .bin file with NO SUCCESS!!! Can't use Prom- Shell in 64 mode cause there's not enough memory available being that the eprom is a 64KB Eprom. So I tried Merlin 128 but coulden't even get the dang thing to even boot. Maybe I have a bad copy? If so, I gotta get a hold of the dude that sold me the promenade clone. Either way, I need some helpful advise as to how I should go about this endeavor. Thanks ahead of time for any and all help I can get ahead of time, Charles

Then Using a HEX EDITOR, Insert "00 20" In the beginning of EACH Segment, (They are removed when you program the Eprom), The files will be 32770 Bytes in size. I did it like that to program an EPROM-PLA chip.. For some Good Promshell info, Check out my information page, ftp://n2dvm.com/Commodore/Programs/Eprom/PromenadeC1.txt
