To all, The Computer History Museum's IBM 1620 Jr. project team has several announcements about Cadetwriter: 1)? Congratulations to Paul Williamson as the first person, besides our project team, to successfully build his own Cadetwriter.? We know that a number of people are building or planning to build one, but Paul is the first person we've heard from that has completed it. ??? If you are building, or planning to build, a Cadetwriter, please let us know about it. ??? Paul's WheelWriter 1000 seems to have a different version of the logic board and/or its firmware than the CHM WheelWriters. This exposed several issues that Paul diagnosed which led to changes in the Cadetwriter firmware that make it more robust. 2)? A new version (5R5) of the firmware is available with these important changes: ??? -? Added support for semi-automatic paper loading. ??? -? Increased the Interrupt Service Routine delay time to deal with overlapping column scans. ??? -? Adjusted the timing of unshifted, shifted, and code characters. ??? This firmware is available at: https://github.com/IBM-1620/Cadetwriter 3)? There is a new Cadetwriter message board at: https://cadetwriter.slack.com ??? There are actually 5 channels available: ??? -? Cadetwriter/announcements - for announcements of new versions of the firmware, documentation, hardware, etc. ??? -? Cadetwriter/description - for a general description of Cadetwriter and links to resources. ??? -? Cadetwriter/building - a discussion forum for those building a Cadetwriter. ??? -? Cadetwriter/operating - a discussion forum for those using a Cadetwriter. ??? -? Cadetwriter/suggestions - a discussion forum for proposed additions/changes to Cadetwriter. ??? If you have interest in Cadetwriter, please register and participate in the discussion. Thanks, IBM 1620 Jr. Team
