Z80-RIO (Z80 Operating System with Relocatable Modules and I/O Management) - a general-purpose operating system developed by Zilog in the late 1970s https://archiveos.org/z80-rio/ #operatingsystem #zilog

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. #zilog

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. Check bitsavers. #zilog

Out there, in the worrying world of today is a little #Zilog #Z80 computer with a mere 64KB of #RAM and running the #1970s CP/M operating system.

This little machine is connected to the #intertubes and it's serving a #singleuser #bulletinboardsystem for you, the worrying souls of #yesteryears to visit.

Take a break from today, connect like it's 1985 - here on RC-BOX BBS, the world's first and (currently) only #rc2014 based bulletin board system in the world!

Check out the #alttext or my #profile info for information on how to connect.

Using the character to bitmap mapping available in the latest #AgonLight VDP firmware, I've been able to transform an ASCII #curses version of Flappy Bird into graphics. Double-buffering ensures the game plays flicker-free. Before and after images included.

Doomsday prepping!

There's a joke about auto-increments and alternate register sets in there somewhere. (-:

Look what I found lurking at the back of my drawer! No idea what it was doing there. I stuck it on the breadboard to straighten the pins out, as they were a bit wonky, but all intact #cpu #zilog #z80 #8bit

Sharp also joined the battle for the best home computer - a kind donor has given us an excellently preserved MZ-731 in its original packaging It is powered by a Z80-compatible processor, addressing 64 KB of RAM, and features a built-in mini plotter and cassette deck.

The shortage of #Zilog chips is obviously hyped. RS clearly has enough stock for thousands of years!
