First, I have a Mini Memory, but after fighting with it for a week, I cannot seem to work out exactly how to create something that will work with Extended Basic & a 32K RAM expansion. So, I've been looking to buy the Editor Assembler package (cart, disks, manual, ref, & keyboard overlay/slip.) Though that might take a while. Until then, I've been working with several emulators to try and get some practice in. The problem is that I cannot seem to write anything that will work. I tried entering a program from the "Introduction to Assembly Language for the TI Home Computer" book available elsewhere here, but it still wouldn't run. I tried the code exactly as written in the TI Basic option of the Editor/Assembler cartridge. I also tried adding in EQU instead of REF for the 2 calls (VSBW & VMBW,) in Extended BASIC. The example program ran fine with (3 Load and Run) from E/A (with the return altered by decrementing twice to freeze at the end.) Am I missing some important step? My code included... It's just a simple program to place text at a specific screen location.
