I designed a type of RAM card to be used as a daughter board for the AIIE 80COL card. Many people may like the 80COL card, but I never used it and had a lot of it in my drawer. *In fact, 80COL is also supported in AII VGA projects, so there is no need to use the 80COL card alone.
For now, it will not be open sourced and will be sold in my store. It will probably be open source a little later, stay tuned…
