Hello 336 is a 33 micro-fard cap and it is 16 volts, for the smd package you will need to find same size
and the line is the plus side, if one burned ot the other may not last as they dry out and short. so you should them both
Harry, I would look at using the 52 pin version of the 68008 as it supports 4 meg of address space and is in a plcc package which uses less space
The kiwi is based on the 68008 https://www.ist-schlau.de/hardware.html
And also there is the Katy which is also using the 48 pin version...
P0 are the data bits connected to thru U2 on the serial board as a buffer, then U2 is feed to the 10 74s373 U1 thru U10 on the display board
P2 outputs P2.0 thru P2.3 connects to U11 the 74154 4 to 16 decoder which is connected to the 10 latches (74s373)
P2 outputs P2.4 thru P2.6 are connected...
Since I am learning as I go this is code fragments I found on the web and am using as a starting point.
I was also playing with some serial port code that will turn on and off segments but not the ones I want

Hello I have a board that is missing its micro-controller, I am trying to recreate it from scratch
It has 24 seven segment displays and 64 leds to show status
each row has a data latch and has 4 driver transistors to turn on and off the displays
It would receive a serial data stream and then...
Hello
I have tried your code but since my programming is almost not I can not figure out how define your column statements, so I just get errors when trying to build it.
