# Resume searching for OpenBSD-compatible non-BGA chips that are similar to the Nuvoton (unlikely to exist on the market, as we have been searching for a while and chips like this tend to be older designs and therefore unlikely to be supported)

# Migrate to a different OS which has ARM926EJ support, such as NetBSD or Linux. Both are considered less secure than OpenBSD, the latter unacceptably so.

# With [http://www.undeadly.org/cgi?action=article;sid=20210423090342 newly added] and [http://www.undeadly.org/cgi?action=article;sid=20210619161607 quickly expanding] RISC-V support in OpenBSD, we may want to consider that architecture more seriously. One key advantage of open source silicon is that we can create a custom, high-performance chip and put it in a QFP package with only the pins exposed that we would need. Next steps would be getting ballpark estimates of taping out our own silicon from [https://www.sifive.com local] [https://openfive.com/custom-silicon/ vendors].
