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ドル 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.
