A couple of weeks ago I picked up a Smith-Corona Memory Correct 400 Messenger at Goodwill. I debated getting it since I already have enough retro stuff around the house, but every single time I’m at a Goodwill I look at all the typewriters to see if they have some kind of serial or parallel port. This one has an external interface which can be connected to a computer using an external box called a Messenger Module.

 

I plugged it in at the store and it didn’t power up at all. They gave me 10 bucks off so I couldn’t resist and bought it. I’m hoping it’s an easy fix, but I can’t figure out how to get the thing apart! The four screws in the bottom just seemed to hold the plastic case to the metal frame, but didn’t allow the case to separate. I can’t find any way at all to get the plastic shells apart without breaking them.

Talking with @johanges on Twitter I’ve figured out that the upper gray plastic shell has to come off first. It has to lift and then slide back which will reveal all the internals. Internally there are fingers extending down to prevent it from sliding, but I can’t figure out what is preventing it from lifting.

 

I’ve searched Google incessantly but I can’t find a scanned service manual. Not surprising since Smith-Corona introduced the typewriter around 1984.

 

I’m offering a reward to anyone who can provide the service manual for a Smith-Corona Memory Correct 400 Messenger, either a physical copy or a PDF at high enough resolution to be useful. If you can get me the service manual I will send you all 60 of the decals & stickers you see here.
