Aunc.1897 net.micro.zx utcsrgv!utzoo!decvax!duke!unc!dce Tue Feb 23 23:27:08 1982 Add On Memory I am assuming that this newsgroup is for people who own ZX-80s and ZX-81s. Please correct me if I am wrong. When I received my ZX-81 kit without the 16k add-on module (should be here soon), I began reading ads having to do with ZX-81 add-on modules. I found an ad for a company that sells a 16k kit for around $70 which can have another module hooked into the back of it, for up to 48k (3 modules). Does anyone know if these modules can take the Sinclair module on as a second or third 16k (i.e. plug one into the computer and the Sinclair module into the back of that one)? I would also like to hear from anyone that has tried to write self-modifying code. I am working on designing a small numerical analysis system for my ZX, but I would prefer to use the built in interpreter for expressions instead of using up memory on another interpreter. David C.
