From the project
Junior-Computer-2 HW and SW
Fourty years later, Joerg Walke created the Junior-Computer 2, which is an expanded version of the original Junior Computer. It contained 32 KB RAM, 8KB ROM and an onboard RS232 serial interface. The development of the Junior Computer 2 is still in progress and you can read all about it on the web-site of Joerg: https://old-computer-tech.net/junior-computer/
