Hi, thanks for sharing the project.
I am new to the MSX world and I am working on a minified pcb with plcc sockets and exposed headers for future development (as soon as everything works I will update my fork). Board will be 5 cm high.

I have some doubts about the bill of materials, is the cpld epm7064 or epm7032? SLC44 or LC44?
The memory could it be SST39SF040-70 or SST39SF040-55?

P.S.: I also opened a github issue but I think posting it here can be seen by more people.

Souceror answered me on github issue but I post it also here in case other people is having the same question.

The CPLD is a EPM7064 in a PLCC-44 housing. The flash you can use anyone that is compatible to the pins. Basically every flash that conforms to the JEDEC standard you can use. Only in programming the flash you have to use another routine. If you program in a separate programmer then this is not an issue.

MSXUSB now turns your MSX into a serial terminal.

Simply connect your MSX via an USB cable to your PC, Mac or Linux machine and a new serial port is detected. Then start Putty, Minicom or Screen and get a connection to the Monitor program.

This Monitor allows you to send Intel Hex dumps of binary data and execute them. A great way to embed your MSX in your modern debugging workflow.

Check out the video on YouTube.

This works also on the RookieDrive with the software from my GitHub.

N.B. if you connect two powered devices you have to take special care, use a data-only USB cable, or check the instructions under the video.
