Thanks for your reply. The Batronix programmer supports flash EPROMS as
well (including the 29C010) in addition to a wide range of EPROMS and
EEPROMS (which it can also erase). Your reply made me decide on buying
it. I'll certainly order a few adaptors from you since I have no way to
make PCBs myself. 

Did you take a look at the Batronix programmer? Would you say that it
would be possible for a beginner to build the kit? The only soldering
I've done so far is installing a socket in a 1541 and soldering a few
cables. The assembled device is almost twice as expensive (although
still affordable).
