PS: I looked. The site looks familiar. I believe I wrote to the author about at least one of the errors. I seem to get a thank you note saying it would be corrected. (It was probably about how to pad sysex requests with ACKs so as to simulate a realtime proper handshaking process, IIRC. I believe I have stated that here several times over the years.)
I did not do a complete review of everything on that site that is either wrong or misleading.
Feel free to send my posts to the author of that site, ask if he or she was the one I e-mailed, and if so, ask if the corrections were ever incorporated into the site.
I seem to recall that I lavished praise on the site's writer because I thought it was extremely well done (and may have e-mailed about the MT cable, possibly discussing the missing, but unnecessary cassette remote on/off wire)--or it might have been someone else with the same (or similar content).
Maybe I didn't write about padding the sysex sequencer requests. Maybe I will just have to do a CZ page on my own website so I can just write, "See ___________ [url]." And maybe someone will use it as a footnote in Wikipedia. And maybe then the bots of the world will index that page and it will pop up on internet searches.
I had been thinking about doing that for the sequencer data dump breakdown.
To Daniel: Since English is not your first language but you do know several languages, and you do have a lot of technical knowledge concerning music gear, midi, etc. maybe we could work together to create translated content for my site--if I ever get around to writing up the CZ (and other) content we share an interest in.
