Schematics and other stuff for The Rainbow Z80 Project
ControlBusLEDs is an open-source printed circuit board by sonic2000gr, from the sonic2000gr/RainbowProject repository on GitHub, published under the BSD-2-Clause licence. It is a 2-layer board with 19 parts on 26 nets, routed with 88 tracks and 0 vias.
It is built around the 74HC240D. Its parts include 8 resistors, 1 capacitor, 1 IC and 1 connector. It belongs with the retro computing and games boards of this library.
This repository contains schematics and info on the Rainbow Project. This is a long overdue (27 years!) project to create a Z80 based educational computer. It is inspired by the home micros of the 80s that used the popular 8bit processor from Zilog.
The Rainbow Project machine planned initial specs are:
Το παρόν repository περιέχει σχηματικά και πληροφορίες για το Rainbow Project Το Rainbow Project είναι ένα έργο που έχει αργήσει μόνο 27 χρόνια! Άρχισα να το σχεδιάζω το 1990 και πολλά από τα εξαρτήματα του (CPU, RAM) είχαν αγοραστεί τότε. Τελικά θα πραγματοποιηθεί ως Project του SchoolSpace το σχολικό έτος 2017-2018. Το Rainbow Project είναι εμπνευσμένο από τα πολλά μηχανήματα της δεκαετίας του 80 που βασίζονταν στο δημοφιλή επεξεργαστή Z80 της Zilog. Χαρακτηριστικά παραδείγματα:
Οι αρχικές προδιαγραφές του μηχανήματος (θα μεταβληθούν στην πορεία):
| Qty | Value | Footprint | References |
|---|---|---|---|
| 8 | 330 | Resistors_THT:R_Axial_DIN0204_L3.6mm_D1.6mm_P7.62mm_Horizontal | R1, R2, R3, R4, R5, R6, R7, R8 |
| 8 | LED_ALT | LEDs:LED_D1.8mm_W3.3mm_H2.4mm | BUSACK1, BUSRQ1, HALT1, IORQ1, M1, MREQ1, RD1, WR1 |
| 1 | 74HC240 | Housings_DIP:DIP-20_W7.62mm | U2 |
| 1 | C | Capacitors_THT:C_Disc_D10.0mm_W2.5mm_P5.00mm | C1 |
| 1 | Conn_01x10 | Pin_Headers:Pin_Header_Straight_1x10_Pitch2.54mm | J1 |
19 parts, built around the 74HC240D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the sonic2000gr/RainbowProject repository on GitHub, at the commit this page was made from: the board is Schematics/ControlBusLEDs/ControlBusLEDs.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
