All parts have arrived. First board is built and successfully reading and writing. No problems found, though I’ve had to remind myself about the sensitivity to cassette volume control setting, before I could get reads to work well off of a cassette recorder. Reading off an iPod is much more forgiving. I need to do some further checkout, but at this point, things are looking good. I also need to print some bring-up guides and burn some PROMs before I’ll be able to ship these units to those who pre-ordered.
