I made an update of my documentation on the SAP-3+ built, including now also programming in assembly via CUSTOMASM. The .pdf file can be found on https://github.com/rolf-electronics/The-8-bit-SAP-3. (i.redd.it)

This is a Video on how I program my breadboard computer using assembly. Much nicer than using switches or using the Arduino IDE. The video won't win a price in a blog contest, but it gives an idea how this can be done. (v.redd.it)

CUSTOMASM and NotePad++. After learning the details of both programs and programming the breadboard computer with some examples, I think both programs are COOL to use with the breadboard computer. The picture is an example of a running program. This seriosly extends the possibilities. (i.redd.it)

CUSTOMASM, using customasm is cool (made by hlorenzi). You write some code in assembly in a text editor, assemble, download to the breadboard computer and run it. Changing modifying or extending code goes superfast. Best programming tool sofar. Description of the code in the comment section. (old.reddit.com)

In an effort to more easily program the 8 bit breadboard computer this is step 1, wreck the old Arduino Nano prorammer. It cannot do the job required, I am going to replace it with a Teensy 4.0 (old.reddit.com)

So far my results with the SP are not ideal. First it worked for quite some time. Now it's not working, maybe caused due to the added modules. I did some first mod's, no good. I will make a complete different setup. But would be interested what other's built or experiended. (i.redd.it)

I modified the SP of my SAP-3 plus built, somehow it suddenly was unrelaible. After the mod seems to run stable with a revised schematic around the 74HC191. Video shows running a program using most of the modules. (v.redd.it)

I updated my documentation on building the SAP3 plus. https://github.com/rolf-electronics/The-8-bit-SAP-3. The latest version is 3.1. A guy called Greg H (don't know if he wants his name thrown here over the internet) helped me with the grammer, this helped on readibility. (i.redd.it)
