Sinclair ZX80 / ZX81 Forums

Please keep us informed here because some people do not want to use facebook. A former member of the german ZX Team, Ali Schams, made some replica cases and I own three of them. You can see the cases in this video (made on the ZX Team Meeting in 2014): https://www.youtube.com/watch?v=tDx58BozFEU Unf...

The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong. It was not an exact clone, as it had a modified ZX81 ROM, but could be fitted with a ZX81 compatible ROM. It came with 2K RAM (expandable to 16 or 32 K), and a sound and joystick port. Pics: http://www.8bit-wiki....

Some extensions are very usefull, i.e. the Dataflash to store programs or the memory extension, the Printer connector, the serial interface. Maybe it is possible to design a pcb with most/all options onboard and the user can decide (via jumperfield?) which option he will finally use / or which parts...

Well done! Any plans to integrate those extensions to a single pcb? A CB2 „Pro“?
