For repair of non-RoHS complint equipment, it is still
allowed to use the
"old" parts. The RoHS rule only applies to new-built equipment.
As a hobbyist you must make sure that you do not mix RoHS and non-RoHS part=
s
because the technique and the material to solder these parts are different.=
A friend of mine who should understand this has told me it's OK to solder
modern, lead-free components with leaded solder (and to solder them onto
old boards with lead 'tinning'), but not to use lead-free solder on
leaded parts. So I should be able to buy, say, modern lead-free resistors
and solder them with leaded solder into my PDP11s.
