AZ80 ROM
About the AZ80 ROM PCB
AZ80 ROM 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 74LS32 and EPROM 27C512. By type, the board carries 2 ICs, 2 jumpers, 2 capacitors and 1 connector.
From the project
Die ROM Platine stellt dem aZ80 Retro System den nichtflüchtigen Speicher zur Verfügung.
Die ROM Platine stellt dem aZ80 Retro System den nichtflüchtigen Speicher zur Verfügung.
Der 32KB große Speicherbaustein (EEPROM) ist in 4 8KB große Teile (Bänke/Pages) aufgeteilt.
Das ROM wird im ersten Speicherbereich eingeblendet ($0000 - $3FFF) und enthält auch die Interrupt Vectoren.
Über die Jumper JP1 und JP2 kann der 8KB Teil des ROMs eingestellt werden, der dem aZ80 zur Verfügung gestellt werden soll.
