Spectrum keyboard and joysticks in ZXBaremulator

[pastbytes]

A few months ago I made a ZX Spectrum version of one of my programs, InDev Tester, which allows you to test the keyboard and different types of joysticks. During the development I had to examine several sources of information, and although the available documentation is complete, I felt that a quick reference was needed. Some time later I wanted to connect an Atari joystick to the RPi to use it in ZXBaremulator, so I took the opportunity to make a schematic showing the connection of a Spectrum keyboard and Sinclair joysticks. As I have done in recent years, I designed the schematics so that they could be viewed on 8-bit machines, in this case the Spectrum. The 256x192 images can be seen on my website: www.pastbytes.com/zxb
I also made a version that can be viewed directly on the ZX Spectrum, which can be downloaded from that same site, in .tap format
It's a very simple program, but maybe like me, someone else might be interested in viewing that kind of content directly on the Spectrum.
Here you can see a short video of the program in operation:
