The successor to the Dialog 4 control was the Dialog 11.
With these machines the control is no longer located in the operator console, but is in the electrical cabinet together with the PC (Programmable Controller), which is now called SPS (Speicherprogrammierbare Steuerung). See pictures at bottom.
This allowed for a smaller operator console, which now only houses the operator panel and the color monitor.The Dialog 11 is more powerful than the previous controls, has a different programming syntax and DNC is standard (?). On the down-side, the machines were no longer provided with board level schematics. This fact must be seen in conjunction with the extreme electronic spare part prices and the significantly high prices for Dialog 11 machines in general. This combination has so far kept the Dialog 11 machines out of the hands of the private user.
Anyone considering to buy a Dialog 11 machine should know that a new electronic board can be very very expensive. Buying a machine with a defect should be done with care.
Two basic types of Dialog 11 equipped machines must be differentiated. The Dialog 11 control could be bought for the "A" machines and for the "NC" machines from about 1988 (NC) or 89 (A). Since the "A" machines were spec'd down for cost reason, they were sold with the old Bosch amplifiers and the older style DC servos. The "NC" type machines have the new style Bosch amplifiers and newer style AC servos. The "A" machines were usually also delivered with very marginal memory, but could be upgraded to 4MB.
While the prices for used machines are high, it must be questioned if this premium against the Dialog 4 machines is justified. It certainly depends on the application.
D11 machines have free loadable Parameters. When buying a machine it should be checked if the machine parameters are included as a backup (possibly on punch tape).
There were a large number of SW versions. Upgrades were done by swapping EPROMs.
The D11 was succeeded by the D12, which was probably mostly just a processor upgrade to the D11.
After the D12 came the D112 for a brief period of time. This control was no longer developed by Grundig, but supposedly was provided by or co-developed with Mitsubishi.
Addendum in late 2009:
With the economic down-turn Deckel prices have dropped significantly and also Dialog 11 machines have become cheaper (in Europe). As this trend continues and all machines get older too, the condition of the individual machine will become more and more important to determine a reasonable price. Already very nice Dialog 11 machines have been seen below 5 figure values. A trend to be observed.
