Lot’s of 3rd party devices that connected to the bus appeared soon thereafter. A few interesting ones I have other than the Voice Synthesizer and the Vox Box
Those were sold under the Radio Shack name. There were also some similar and better ones from third parties.
are an Exatron Stringy Floppy and a Cryptext hardware encryption device.
There was a software intensive third party expansion bus serial printer interface early on. It was supplanted by the TRS-232 (cassette port to serial printer!)
(Not to be confused with numerous other products named "TRS-232") In Googling for it, I stumbled on http://ianmav.customer.netspace.net.au/trs80/ who makes a Model 1 to hard disk cable, a doubler, a CP/M "mapper", etc.
