Wo FPGAs sind, ist Udo Möller meistens nicht weit. Dieses Jahr am VCFe hat er darüber referiert, wie er einen BBC-Computer (Basis MOS 6502) in einem FPGA nachmodelliert hat.
Hier könnt zum nachschauen:

@samsoniuk@xadh No, they didn't. They only used the same bus protocol as the 68000, as IBM did not intend to create a whole world of interface logic, but rather use existing designs.
The silicon is way different from the 68k. There's a detailed design article in one of the NATO tech reports.
@samsoniuk No, it didn't. At least not the way the SuperH did.
68020 instructions were between 16 and 160 bits (2-20 bytes) long
SuperH were always 16 bit. No exception. No extension.
That's the huge point and the very reason even ARM had to licence Hitachi's patents to create Thumb

42 YEARS AGO! On 11 Apr 1984 I launched the Amstrad CPC464 - the first affordable all-in-one home computer. On other computers you had to use your home TV as a monitor and also plug in a cassette player. The CPC464 had it all. Read all about it here 👉https://t.co/fW0aW9nrpr
@loudscotsbloke So at the heart an Apple II stripped of bells and whistles and forged into a single configuration setup perfect for a cost effective school/training setup.
Kinda like the Laser 3000 of the same time - just more restricted.
@loudscotsbloke It's way more than just BASIC. Most I/O (soft switches) are at the same location with same function, Even it's graphics uses the same 'weird' structure- except Higres2 being at A000 instead of 4000, giving more continuous RAM
Not a 1:1 clone, but offers reasonable compatibility.
