A Thank You goes out to @averyredbox.bsky.social and @ajfabio.bsky.social who both surprised me with a gift in the mailbox this afternoon: Two more RAM-9 chips!

What's RAM-9?

That is the part number for the super-proprietary ram that has only ever been used in hardware from Four-Phase Systems. If a ram chip goes bad there are no replacements because this was made before more standard DRAM was available.
