[Coco] "Did I do that?"

[Allen Huffman]

At last weekend's CoCoFEST!, I picked up a bundle of stuff that included a Rulaford Research CoCo MIDI hardware interface and some software. This was sent off to Rogelio, and he received it today. When he wrote to let me know he had it, he mentioned that he had flipped through all the documents that came with it and said he didn't realize I wrote the technical manual for the MIDI pak.

And I didn't either.

He sent me some photos, and it has slowly returned to me. I had ordered CoCo MIDI Pro and a Casio CZ-101 Librarian from Rulaford, and that got me in touch with Cecil Houk about MIDI stuff. I rewrote the interface for the Casio app, and wrote a new one for the Kawai K1 synthesizer. I guess this is what let me to learning how the hardware worked.

In the special thanks, I thank Lester Hands for providing the original documentation on using the MIDI pak, and a friend of mine, Mark Thomas, who looked up the details of the MC6850 ACIA chip that it used. In the document, I provided examples of using the pak from BASIC and assembly, including a small BASIC loader that gave two routines that could be used for reading and writing data in assembly.

And I had completely forgotten I did that.

Thanks, Rogelio!
