Thank you for liking my #Fully manual PROM programmer & #6502 Computer runs calculator! This PROM programmer provides a good understanding of the PROM writing principle. The calculator program was very difficult for me to keep within 1 kbyte.

Thank you for liking my #Homemade Operational Amplifier, #CMOS Homemade Operational Amplifier & #Homemade Successive Approximation Register ADC! 

I have published these so that they can be used for educational training purposes.
Several students at a college in Canada are currently trying their hand at their own practice based on this SAR-ADC article.

Thank you for liking and following my #6802 Serial Terminal & #PERSEUS-9 homemade mobile 6502 computer! When I built my own 6802 terminal, I had a lot of trouble even displaying a single dot on the display modules. But that made it easy to develop software for the display system of PERSEUS-9.

Your projects are absolutely amazing and incredibly inspiring! I really admire the unique style and attention to detail in your builds. I hope you continue creating such fantastic projects, they are a huge source of inspiration!

I also have an HCMS-2903 and two HDSP-2000 displays in my parts bin, and I’ve been thinking about using them in a future project. Seeing your work makes me even more excited to experiment with them!

Thank you for your comment. I recognized the importance of the enclosure myself as well as circuits when I was 15. I like designs that are both retro and futuristic and will last a long time because I believe that cutting edge designs become stale over time.

That's also what led me to LED dot displays. I used a transparent red acrylic sheet from a home improvement store as a filter, which is beautiful and increases the contrast of the appearance.

And, thank you for liking my #Prehistory of my homemade PERSEUS computers & 6502 standalone computer & PERSEUS-8 homemade 6502 computer! Even though I was able to build my own computer when I was 20 years old, I could not build an interpreter language like Mr. Bill Gates and others. These are projects in which I tried to overcome that setback at the age of 60 by building my own computer again with the level of technology available at the time, and tried to build a somewhat practical floating-point interpreter on my own.
