Weapon of Choice: 1983 Brother EP-22.
Until I actually picked one up, I thought that the Brother EP-20 and EP-22 were the same size. Turns out, while the top shell for both was clearly pressed from the same mold, the bottom shell on the EP-22 is almost a quarter inch deeper than the EP-20. It was a subtle difference, but I felt it the instant I picked the EP-22 off of the Goodwill shelf. Yes, I broke quarantine to hit a thrift – I needed the release, and I had a feeling that the Thrift Gods would be smiling… I tried a lot of different settings on my period-correct 1984 TRS-80 Model 200 trying to hit on the right one, including 8-bit and 7-bit word length, Even and No Parity, 1 stop bit, flow control enabled and disabled – no combination I’ve tried results in a handshake..
Speaking of the EP-44, I found out that there was also an EP-41, which was the non-data-connecting variation of the EP-44, and sporting a black shell instead of the EP-44’s white shell. This appears to be the only variation that was given a name other than its “EP” designation: “Travel-Riter”. I wonder if they immediately got sued by Remington, and if that’s why you *never* see this variation in the wild.
I found a pic of the EP-22’s user manual, and more importantly, the “How to connect to computer” manual. I really want a scan of that one. Have you got it? (:
