AZ80 CPU
About the AZ80 CPU PCB
AZ80 CPU is an open source PCB design by attraktorhh, published on GitHub under the MIT license. It is a 2-layer board measuring 110.3 × 40 mm, with 7 components from 7 distinct parts.
Other key parts include the Z80CPU. By type, the board carries 4 resistors, 1 IC, 1 connector and 1 capacitor.
From the project
Die CPU Platine ist das Hirn des aZ80 Retro Computers und verarbeitet die Daten.
Die CPU Platine ist das Hirn des aZ80 Retro Computers und verarbeitet die Daten.
Der Switch ist normalerweise in allen Positionen auf Off gestellt und erlaubt in Zukunft weiteren Karten die Steuerung der CPU.
- 1 - WAIT - 2 - NMI - 3 - BUSRQ - 4 - BUSAK
Das WAIT Signal hält die CPU an und wird aktuell nur beim Betrieb der SN76489 Soundkarte genutzt. Diese ist so langsam, dass sie die CPU anhalten muss, bis der nächste Befehl gesendet werden darf.
