Title Description Computers
8K Non-Volatile Memory Kit Review of Hunter board. The Non-Volatile memory (NVM) kit is a battery backup powered RAM board that is primarily designed to fill the transparent address area between 8K and 16K in the Sinclair ZX80/81. The key feature of this product is that with the onboard battery, the routines stored in NVM are retained even with Sinclair ZX81, Timex/Sinclair 1000
Another Look at 450ns EPROMS vs the ZX81/TS1000 Paul Hunter’s comments on using 450ns EPROMs on ZX/TS computers (May83) strike me as true but incomplete. Paul shows how to add a flip-flop to delay the computer by inserting wait states and thus make the computer read slow EPROMS. You can use another chip select scheme to cure access problems without adding circuitry or Sinclair ZX81, Timex/Sinclair 1000
