Hello,
I present the following project that I have started to develop:
The initial use I had in mind for it is to be able to host the Micro8088 or Xi8088 projects of Sergey Kiselev, to which we should add the rest of internal ISAs without brackets for their correct operation. However, as I was placing components I have realized that one could go further. In the area of the I / O shield would be fixedly a VGA with MonochromeVGA integrated, and two DB9. These will then be used internally to connect to two serial ports on PC (COM1 and COM2), or a serial port and a standard Atari Joystick, etc ...
It would also have a 16-bit PC / 104 socket. This would serve, in addition to being able to put a VGA in this format, other cards or even a complete 286/386, which as there is available a 16-bit ISA with bracket would give game. If the PC / 104 is not used, you would have another 3 internal 8-bit ISAs available ... for example to place the low-profile RTC I designed or the Internal OPL3 sound card also low-profile I designed, and with the HDAudio connection you could connect to the front of a case of this format, many current cases already have it.
The idea, with some additional holes added that will serve as a support to add a second PCB higher in the I / O shield to add, this time, concrete things for which project. For the PC you could add a Compact Flash with its corresponding IDE connector, a parallel port, etc ...
Other projects adapted to either of the two formats could be added (as MiSTer FPGA DE10-Nano), although PC / 104 is more compact in height and would perhaps allow its use in slim type cases.
Official Mini-ITX measurements: 170 mm (length) x 170 mm (width)
Customized to locate ISA1 external slot, and give margin to the other connectors: 184,899 mm (length) x 181,026 mm (width)
To take into account when purchasing a Mini-ITX format box for the project
Although I share the sources of the project, it is still in the prototype phase and could contain bugs that should be solved, being the PCB is 4 layers.

What do you think? Ideas or suggestions are always welcome.
