They had no choice. Motorola discontinued the MC6809 line. By 
1989 Tandy Coco was a major user of the part. Secondly no one 
was using 3 micron NMOS wafer technology anymore. The 6809 
was originally done on 3 micron 4 inch wafers. That was 1977 
technology. By 1989 0.75 micron was already old technology and 
nobody was doing new designs in NMOS. It was costing them too 
much to keep the lines operating for production.  

Today if one were to do a chip like the 6809,it would be done with 
0.13 micron CMOS technology and would operate with a core 
voltage of 1.8 volts and I/O of 3.3 volts. CPU speed would be in the 
400 to 800 MHz range. 

Wished I had a spare half a million dollars and I would do that.
