A project log for Numitron Hexadecimal display module

Another hexadecimal display, this one is sans transistor for the extra vintage touch, and uses only Soviet-era parts

I soldered the 10 PCB :-)

The modules work great. I've had only 2 parts wrongly soldered (one reversed diode and one reversed relay) but they were easy to spot.

The IV-9 are soldered with "loose" pins so they can be adjusted for later mounting.

All these modules, as well as the 5 pre-series, will be used for the #Hardware assembler / EMUI of the #YGREC8 :-)

woohoo! what fun to read your logs!

Thank you !

And I hope it helps you as well :-)

I hope the "bipolar diode ROM" trick will be reused by others, such as maybe a microcode ROM.

I have reused this technique almost verbatim to drive the #YGREC8's "disassembler display":
