Before you get a working home build computer running you have to build minimal OS.
(the OS must be burned in a ROM chip after power on the MCU will run from reset vector at $FFFE)
So first step are writing an assembler on PC for your target MCU/CPU.
Of course I found 2 old motorola assemblers but they are for DOS and closed source.
The advantage (if you are write your own assembler) is you get a pro of the target CPU in short time.
I combine a lot of old ICs: (I know all IC by name in my mind)
MC6874 (CRT video)
2xMC6821 (PORT I/O)
2xSN76489 (complex sound gererator)
2xYAMAHA YM2612 (FM synth)
of course many 74's (OR,NAND,XOR ...) and 8-bit bus/line drivers
the only one modern IC are the PAM8403 a tiny 5V stereo amplifier 2*3W
I emulated a C64 and TRS-80 in the past
so my idea are to create a simulator with FLTK
than I can play with the IC's before I solder it.
In theory you can compile FLTK for an 8 bit computer too.
The problem are a the missing C++ compiler for 8 bit CPUs
I will inform you if I made a web page of my old school computer project.
(or if I upload stuff on youtube)
