ZX-Uno

The author of a previous hack that combined a physical TMS99105 CPU and an FPGA to create a clone of the TI99/4A, has now created another version (soft-cpu branch) which includes the TMS9900 CPU core written in VHDL.

https://github.com/Speccery/EP994A/tree/soft-cpu

Would it be possible to port this to the ZX-UNO ?

Thanks!

Интересный проект, попробовать то можно, НО!
похоже это для этой devboard

и похоже доступ к памяти 16-bit, и памяти 1Mb
если конечно тут это задействовано - то проблематично. imho

If it is possible, probably, Quest or Jepalza (to name two of the people I know they like to do these things) will put their hands on it I wish I could involve on this, but my FPGA-time is already full

шина ДАННЫХ - 32-bit, из нее делается 16-bit
первые 512kB - под картридж, вторые 512 - подо все остальное
клавиатуры PS\2 - нет
клавиатура сделана матрицей на порту расширения
загрузка с SPI-флеш. Хорошо если не с нулевого адреса:)
ну и RX\TX .
