Getting tape made to order might come in handy if you
want odd sizes.
5 and 8 channel tape is fairly common, but there was also 6 and 7
channel tape (in widths specific to those types) which is far less
common. I haven't seen 6 channel tape since the 1970s when it was still
used in typesetting equipment, and I never heard of 7 channel tape until
recently (it was used on some 1960s era machines).
6 and 7 channel tapes should be the same width, i.e. 22.2 mm. The LGP-30
for example natively uses 7 channel tapes (was also common in the former
GDR) but punches only 6 channels.
