TL;DR; I’m repurposing these keyboard+cases into
I stumbled onto a couple of items called AlphaSmart Pro. At first
They look a lot like the
The AlphaSmart Pro wasn’t a 1980s general-purpose 8 bit home computer. It has a lot of the 8-bit guts to have been a home computer – 8-bit processor, RAM, ROM, etc. The AlphaSmart Pro was instead used to type text away from a PC and then return to the PC and upload that text through a PS2 keyboard port. Here is a bit of info from Wikipedia: https://en.wikipedia.org/wiki/AlphaSmart
There were quite a few of those 1980s computers that I had thought would be great to have, and I’ve even had a few come through the lab. I did have a TRS80 Model III at one point that I used as an interface (controller) to some electronics. I think that a small 8-bit style of computer would be nice to have on my workbench. Something that can give me I/O lines to control, serial signals, etc.
Besides the Z80 and 6502 computer modules, this project will be great for interfacing to the CircuitGizmo MicroMite devices. These all run BASIC and are a 32-bit implementation of
Once the AlphaSmart board is removed from the case there will be plenty of room to stuff a couple of PCBs to do the jobs that I want.
The LCD will come in handy for some “macro functions” like displaying the current baud.
I have an old Raspberry Pi (first version, no Ethernet) that I can use for HDMI output. (See next post)
