A very old
computer made by
Radio Shack circa
1980. Without an
expansion interface, it had a maximum of 16K
RAM. Interestingly, it has a
Z-80 processor, just like my
TI-85 Calculator.
Monochrome display, no real
graphics capabilities. But it did have some
funky block drawing characters in the
extended portion of the
character set.
A version of BASIC was included in the ROM. There were actually two versions. Level I Basic had only 26 variables, two string variables (A$ and B$), and one array. It only generated 3 error messages: WHAT?, HOW?, and SORRY. Level II Basic has many more features, including the ability to save to a cassette tape and more cryptic error messages. In fact, the machine didn't even support disk drives without the expansion interface (which also let you get up to a whopping 64K RAM!).
