Howzzat for a terse answer? :-)
Your '87 9k has an LH 2.2 ECU and the '89 900 has an LH 2.4 ECU.
The saving thing is that the 2.2 has a 25-pin connector and the 2.4 has a 35-pin connector, so you can't just plug a 2.2 in there and damage it from the different AMM wire assignments.
You need an LH 2.4 ECU from an '89 or '90 900S. ECUs from 900 turbos from those years would most likely work, too.
You may (and I emphasize "may" because I haven't tried it in my car yet and I haven't seen a wiring diagram) be able to use an ECU from an early '89 (pre-DI) 9000
