Beyond the TS 1500 (ZX81/TS1000) User Manual: Your RAM Memory

In order to become more than a novice programmer, it is essential that you understand completely the structure of your Random Access Memory (RAM) and how it functions. This is also a prerequisite for future articles in this series. Much of the material presented in my articles is written to correct, what in my opinion are misconceptions spread or perpetuated by others. I urge you to try the routines presented as proof of the material. I use a TS1500 and this is the reason the ZX81/TS1000 are parenthesized in the heading. This is also another reason to try out the routines on your own computer.
