They stole your 85? that's weird... nobody steals 85s at our skool.
people steal the teacher's 83s and 86s and 92s over here...

z80 is more x86 based. The z80 [the CPU for the 80,81,82,83,85,86] has
many instructions towarded one register. With the 68000 processor [CPU
of the ti-89 and ti-92], all instructions can access the 8 data
registers and all the 7 address registers. I haven't tried much z80,
but 68000 is so very easy to work with.
on the z80 instructions are like...
mov [target],[source]
on the 68000, instructions are big endian..
move.l [source],[datatype]
I would say that the ti-89 is
also a more welcoming platform because no one uses 85s anymore!
