Imagine a true 6530-002 and 6530-003 replacement , the RRIOTs of the KIM-1

Now with modern FPGAs you van do that: a 40 pin PDIP replacement: the reDIP RIOT is made for that purpose.

Here is the code for the reDIP to make it a 6530-002 or 6530-003:

Github with gateware for Commodore MOS 6530 RRIOT

Since the 6532 is in fact a subset of the 6530 (no ROM, more RAM), it seems not too difficult to make a 6532 replacement this way.

The reDIP RIOT is an open source FPGA board which combines the following in a DIP-40 size package:

Lattice iCE40UP5K FPGA
1Mbit FLASH
5V tolerant I/O
The reDIP RIOT provides an open source hardware platform for 6530 RRIOT / MOS 6532 RIOT replacements.
