Gang,
I was looking through the December 1978 issue of "Kilobaud" and it gave a source code listing to speed up the cassette interace of the TRS-80 model 1 to 1000 baud. It said that the level one machine operated at 250 baud, and level 2 operated at 500 baud. The author said that by loading this code (modified from that in ROM) and executing it he was able to load a 14k program in two minutes, down from 7 1/2. The one thing he did not say was how many errors there were in the program when it was loaded at that speed, making it sound as if there weren't any. Perhaps Radio Shack was trying to sell more expansion interfaces and disk drives.
My local university has these magazines available for the public to view, and copy machines to use, too. Perhaps a trip to your local university will yield some valuable nugget of information.
