Subject: Re: EPROM programming (27c160's)
I'm still
waiting for an EPROM programmer with Linux software available.
Make one!. The programming specs for most EPROMs are available, I think...
I'm actually tempted to do a GAL/fuse-PROM programmer seeing as my
GALBlast won't work worth a damn on this machine :(
Are enough of the programming algorithms documented to make this
possible? For the fusible-link PROMs (and PALs), every manufactuer seemed
to do it their own way. Some would release the programming specifications
(they were even sometimes in the data sheets), others wouldn't. Some
stopped releaisng them, so you could get hand-program the early parts but
no the later ones.
Ditto for GALs (although, actually, geting any programmign specification
for those was 'interestings')
