> Can't help you with the manual but I just wanted to say that the 1051
> was one of my favorites. Loved the PLLs. I worked on an upgrade for
> Stewart Warner back in the early 80s. As part of a prototype I put two
> Z-80 systems in the space between the front panel and the main gear.
> Part of its purpose was to interface to the 1553 bus. I also implemented
> a DDS in TTL for fine tuning. I still like tube front ends for mil
> radios for ruggedness. But you can't sell it because of wear out issues.

> The Navy didn't buy in to the prototype. Collins beat us. The code for
> the processors was written in Forth. The Navy "code inspector" said it
> was some of the best written code he had seen in several years. We also
> could complete a design cycle - including code - in a month. The Collins
> boys had a team 10X as large as ours (we had 3). And it took them 6
> months to complete a design cycle using "C". I was project manager and
> lead engineer. I was mostly hardware but I did some software and rode
> heard on the coders. Forth was my idea.

> I also put a Z-80 inside the companion 1KW transmitter. The RF inside
> the transmitter was a few volts per inch. I used a sealed box and a  lot
> of feed through filters. It worked the first time. 
>
> I also worked with the gear in Navy ETA school. And went on to become a
> Nuke so I didn't see that radio gear again until about 15 years later.
