Alternatively google for 'Am26s10cn'. It is
about the closest to a true unibus transceiver that is still available (in a DIP package
even).
TI makes it, available from DigiKey.
Unfortunately the max Vil and min Vih for the 26S10 are significantly
different than the DEC specs. For a small system you might be able to
get away with using it, but noise immunity and general reliability will
be worse.
