ArchiveOSZ80-RIO (Z80 Operating System with Relocatable Modules and I/O Management) - a general-purpose operating system developed by Zilog in the late 1970s <a href="https://archiveos.org/z80-rio/" rel="nofollow noopener" translate="no" target="_blank">https://archiveos.org/z80-rio/</a> <a href="https://mastodon.social/tags/operatingsystem" class="mention hashtag" rel="nofollow noopener" target="_blank">#operatingsystem</a> <a href="https://mastodon.social/tags/zilog" class="mention hashtag" rel="nofollow noopener" target="_blank">#zilog</a>

Óscar Toledo G.The Hitachi HD64180 was an improvement over the Z80, with an 8x8 multiplication instruction, and able to address 512kb of memory. Zilog licensed it back as the Z180 and added a further address line to handle 1 mb of memory. <a href="https://mastodon.social/tags/zilog" class="mention hashtag" rel="nofollow noopener" target="_blank">#zilog</a>

Óscar Toledo G.The Zilog Z280 microprocessor. Able to address 16 megabytes of memory, and with MMU for 64k code area and 64k data area. It wasn't so popular, so it ceased manufacturing, but for some reason, Zilog sent all datasheets and manuals to oblivion.

So just don't worry. Fun fact: before I discovered <a href="https://oldbytes.space/tags/rc2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#rc2014</a> I believed that the Z80 was already out of production. Maybe there'll be some licensing going on and 3rd party manufactueres will re-issue the chip. And let's not forget the land of the dragon, where counterfeit silicon has a long tradition. So much on that topic.Still, I'm glad to have these babies in stock ...<a href="https://oldbytes.space/tags/EndOfProduction" class="mention hashtag" rel="nofollow noopener" target="_blank">#EndOfProduction</a> <a href="https://oldbytes.space/tags/RetroComputiing" class="mention hashtag" rel="nofollow noopener" target="_blank">#RetroComputiing</a>
