Hi
I use a 6502 co-pro with DFS 2.26 -- the tube code is in there too.

As for blowing eproms, this is what I do.

I use a Genius NSP universal programmer (works with Windows via a serial
port) bought on Ebay for around £35 inc postage (checks: there are
several on Ebay at the moment, see e.g. Ebay item #5834297970): this'll
blow anything.  The software is in broken English, but you can figure it
out, and everything works OK.

I bought some Atmel eeproms (AT28C256 -- about £5 each).  These are 32K
eeproms that just plug straight into the BBC rom sockets once
programmed.  As eeproms, they are a doddle to re-program -- no UV to
mess with.  Use the software to program the ROM image into the top half
of the eeprom, as that is where the BBC will look.  Easy as pie.

Hope this helps.
