I recently aquired a Tandy TRS-80 Model 102. I’ve been looking for a while and finally managed to bag one in remarkable condition.

I’ve had a play with the pretty good Microsoft BASIC implementation and would now like to explore alternative programming languages. Intel 8085 assembly language programming is well documented but there may be the possibility of targetting Small-C. I have previously been able to target a MC68000 single board computer with a C cross-compiler, although this is a trickier possibility based on the constraints of the machine.

Possible goals for this month include:

• Explore 8085 Assembly language programming.
• Investigate the feasibility of targetting the Model 100/102 with Small-C.
• Document the process of creating a custom ROM.
• Use the Model 102 to write at least some of the blog posts.
