  • DIP40 Frame of Fame
    The almost finished frame missing one chip

Background

The first microcontroller I learned to program and got to understand the architecture of was the Atmel ATmega16/32 in a DIP40 package programmed with a STK500 board that can also be found on The Circuit Board Coffee Table. This chip fascinated me with all it’s build in peripherals inside a single chip. Other chips that I later played around with were the Microchip 16F877 and 18F4550 with USB interface. When I got interested in retro computing I came to know about 6809, 6502, Z80 and 8088/86, which all shared the common DIP40 package. I found myself collecting these devices without really knowing why and not knowing how to display them. I just knew I didn’t want to start a huge CPU collection, so I limited myself to the DIP40 form factor. Then at a natural museum’s shop I saw this little showcase with butterflies, wondering how cool it would look like with old DIP40 ICs in it instead of animals. I found the perfect frame for the showcase with an IKEA HOVSTA frame that had the right depth.

The ICs would be mounted in precision machined IC sockets soldered onto prototyping PCBs so it would be possible to swap them around if some was added or removed from the collection. 

Scope of the collection

The overall theme of the DIP40 Frame of Fame is famous DIP40 microcontrollers and microprocessors with a few exceptions by type and package. Since the DIP40 package is now almost obsolete with new microcontrollers, breadboard friendly microcontrollers, mounted on a DIP40 size breakout board, are also included in the collection. This is my little version of a CPU collection with items I think has an importance to computer history. The name DIP40 Frame of Fame is somehow self explaining but is inspired from the Chip Hall of Fame.

  • The board is mounted in the cardboard that comes with the frame…
  • …using hot glue
  • Almost finished frame
  • Close up view so most of the labels can be seen
  • Top row is oldest going from left to right.
  • Even closer

Below is a list of the 21 ICs that can be seen in the DIP40 Frame of Fame sorted by release date and with a short description of specifications and a justification for relevance.
