About the Hannes512 PCB

Hannes512 is an open source PCB design by SukkoPera, published on GitHub. It is a 2-layer board measuring 54.3 × 72.2 mm, with 24 components from 16 distinct parts.

Other key parts include the MOS_7360_TED, AS6C4008, 74HCT02, NE555 and 74HCT573. By type, the board carries 9 ICs, 7 capacitors, 4 resistors and 3 connectors.

It belongs with the retro computing designs in this gallery.

From the project

512 kB RAM Expansion for the Commodore 16/+4

It was pretty obvious that switching to a modern SRAM would alleviate both issues, so I went looking for modern chips I could use and the Alliance AS6C4008 turned out to be a perfect match. Besides, it is 512 kB so I even went beyond the original goals and made all of that available to the C16 (even though that can create incompatibilities, see below).

One exception is that I reintroduced the ESD protection diodes for the TED that were featured in Fixteen. They are U8 and U9 and they are optional.
