…is the TI-66 Programmable Calculator.
It is small and light and Turing complete. The programming records key presses as well as allowing for entering instructions in an assembly-like language, so it is a great primer for learning full Assembly language programming, which is what I am doing now on my HP95LX.
I found this on eBay cheaper than they usually go for. I still need to make a data transfer cable for it, they are really expensive. Once I have the cable I can transfer drivers to the handheld so I can use Compact Flash cards for data transfer.
As you can see from the picture, I am using to learn Assembly Language Programming under DOS. For now I am using the debug program to write small programs in Assembly, since I can’t put other software on the machine yet.
This was is my first – no, my second actually- pocket computer. I wrote some Basic programs for a jet engines class.

This blog will be mostly about Mihai Pruna’s collection of handheld computers and topics related to retrocomputing.
