- The Intel MCS-48 series, Intel's first microcontroller, is perhaps the most-scavenged CPU. The series includes the 8048 (used inside IBM keyboards), the 8035, the 8042 (used on the IBM PC AT motherboard), etc.
- According to http://coprolite.com/art12.html , "I'd love to hear about where you found your 8048. Take a picture of the host that you remove it from (CD player, truck, refridgerator, whatever) and I'll put your picture on a page that chronicles our adventures sifting through the rubble."
- Andrew Rossignol uses Intel 8035L microcontrollers from the Using MCS-48 series: discussion https://hackaday.com/2013/07/24/using-30-year-old-microcontrollers/ and more discussion: https://www.reddit.com/r/electronics/comments/1imy4i/programming_the_vintage_30_years_intel_mcs48/
- There has been some discussion on retargeting SDCC to the MCS-48 8035 https://sourceforge.net/p/sdcc/discussion/1864/thread/cc844f17d4/ and https://sourceforge.net/p/sdcc/mailman/sdcc-user/thread/4D3F206A.3010906%40neurotica.com/
- Intel datasheet for the 8048 / 8035 / 8049 / 8039 / 8050 / 8040 / 8748 / 8949 microcontroller: https://wiki.console5.com/tw/images/4/4a/MCS-48.pdf
- Modders generally pull their MCS-48's external access (EA) pin up to +5V in order to debug and run their custom code from external memory (bypassing the internal program memory, which cannot be changed in most chips in the MCS-48 series).
- Chips in the Intel MCS-51 series, including the 8051 and similar chips, are perhaps the second- most-scavenged CPUs.
- After the 8048, the 8051 and similar chips are perhaps the most-scavenged CPUs. http://www.8052.com/ has a FAQ and a discussion forum for the 8052, 8051, 8032, and 8031 along with more modern derivatives of these chips.
- SDCC was originally written to support the 8051 and still supports the 8051 and many variants. https://sdcc.sourceforge.net/

- Take apart a Compact Fluorescent Bulb
- "Das DereLicht Receiver": a ham radio receiver built only from the electronic components inside an old compact fluorescent bulb.
- "Der Nauen Crosses the Pond" describes ham radio transmitter and receiver built from a relatively low-frequency transistor from a compact fluorescent bulb, using magnetic frequency doubler technology.
