+We received eight of these microprocessor trainers on 5/24/2022. At least two had issues with the copper traces rendering them unusable. Some others may have other minor issues (speaker connection broken, etc.).
-Unfortunately, they did not include any copies of the companion book ("Practical Microprocessors") or the Service Manual. They are still potentially useful as technology demonstrators (i.e. "hey, you soldered a badge- this is what can happen if you scale up from there")
+Unfortunately, they did not include any copies of the companion book ("Practical Microprocessors") or the Service Manual (I have since found a PDF of the English version of the book -sdh7). They are still potentially useful as technology demonstrators (i.e. "hey, you soldered a badge- this is what can happen if you scale up from there").
 We did find the assembler code for the ROM, which is helpful for running the ROM demo programs.
