BTW, I wonder if it was possible to replace these simple but out of production SSI and MSI port components by some kind of programmable logic. ...Well, better said: if it's worth to do it. But I suspect it's getting to be reasonable. The 6530 looks pretty simple (except for its internal RAM and ROM that could occupy lots of CLBs -- still some 100 bytes of RAM could probably fit even in a CPLD). I know, Xilinx offers flash based, 3.3V / 5V CPLDs. These chips aren't even expensive (few dollars, depending on capabilities and packaging).
