More 6809

Just to let you guys know, there were much larger 6809 systems. The 6809 was a great processor. I worked for many years on a 6809 system with 4Mb ram, scsi disk interface with hard drive and ms-dos 3.5 floppy, 68030 floating point co-processor. This was in use from about 1980 until 1992, when superceeded by the new system. The 6809 was retained for so long due to the software investment. Originally it had a custom disk interface to 5.25 floppy only, which was upgraded to scsi and ms-dos fat file format around 1988. It also originally had a smaller stack based floating point chip, but we needed faster float speed for coordinate calculations. So we upgraded to using the floating point co-processor that was used with the 68030. All of this and the memory managment was custom hardware. It started out being a couple of boards, but later was reduced to one board for all the cpu stuff. These systems also had several other 6809's in them. Originally the pattern rec vision system used one also. The material handling system, and motion control axis used the smaller 6805s in them. It was used on the Kulicke & Soffa wire bonders, used to manufacture computer chips, including Motorola of course. http://www.kns.com/prodserv/equipment/8060.asp Chad Martin
