Panasonic MN1400

I bought Computer Perfection, thinking it had a TMS-1100, but instead it had a Panasonic MN1400. It looks pretty similar to a TMS-1100- 28-pin DIP, 1KB ROM, 64 nibbles RAM, instruction and output PLAs.

Here are some datasheets that I found:

MN1400 Family

MN1400 Family-1

MN1400

Here are a couple of the several patents that include source code that I found:

4302778 - Zenith

4458996 - Canon
