If you have Revision G motherboard then I expect you have the 1.44 
upgrade done. Look for a bunch of jumpers on the underside.

If you want to update your MB to the G level allowing 1.44 Sony (?) 
floppies (& you need RV5.0 EPROM) then here are what I think are all the 
mods:

1) Cut traces @ W5, W6 and W7
2) Jumper W5 (connected to U27-P3) to U72-P9 (unused 7417 gate).
3) Jumper U72-P8 to W7 that connects to J14-P1
4) Jumper other side of W7 (ground) to W6 (side connected to J14-P4)
5) Jumper U27-P1 to U72-P5 (unused 7417 gate)
6) Jumper U72-P6 to J14-P16 (currently N/C)
7) Jumper W6 (connected to CHNG2 - J13-P1) to W5 (connected to J14-P2 - 
/SPARE)
8) for RV5.0 EPROM check that W2 is cut

I think that is all of them. I need to draw up the revised schematics, 
but no time! Will do that over the next day or two..
