I have uploaded a new ZIP file with the latest Version 1.21 Beta firmware. The file includes the new manual in draft form. A couple of minor changes have been made over the past couple of weeks. These include a minor timing change to iambic Mode A (most people won’t notice any difference). I also added stuck button/key detection during the power-on tests, and fixed the /Y command (MYCALL) in PC terminal mode.
Unless any problems are found in this release, I’ll release it for general use on 2/15. It will also be loaded on the next production run of MasterKeyers, which are being built now. As always, please let me know immediately if you find any problems.
I’m also out of stock until the new batch is ready – probably late February. Cabinets are in manufacturing now, and the internals will be ready before they arrive.
