## Introduction
|
||
Основной задачей данного проекта я поставил создание наиболее близкого к оригиналу клона персонального восьмибитного компьютера "Дельта-С", который в свою очередь является клоном ZX Spectrum 48K. Выбор модели был обусловлен давней мечтой об "улучшении" оригинальной машины, которой я обладаю с 1991 года. В процессе работы цель проекта несколько раз корректировалась и вместо точной копии стала некоторой "вариацией" на тему оригинала, с небольшими корректировками.
|
||
|
||
## Features
|
||
- High-performance microcontroller
|
||
- Multiple digital and analog I/O options
|
||
- Onboard peripherals such as LEDs, buttons, and connectors
|
||
- Expandable with additional modules or shields
|
||
- Compact form factor for easy integration
|
||
|
||
## Getting Started
|
||
To get started with Delta-S-M Ver.1.0, follow these steps:
|
||
1. Clone or download this repository.
|
||
2. Open the Gerber files in your preferred PCB manufacturing software.
|
||
3. Verify the design and make any necessary adjustments.
|
||
4. Generate the necessary manufacturing files (e.g., drill files, copper layers).
|
||
5. Submit the generated files to your preferred PCB manufacturer.
|
||
6. Review the manufacturer's guidelines and requirements for PCB production.
|
||
7. Proceed with the manufacturing process.
|
||
8. Once manufactured, assemble the components onto the PCB following the provided bill of materials (BOM).
|
||
9. Power up the Delta-S-M Ver.1.0 board and start exploring its capabilities!
|
||
|
||
## Folder Structure
|
||
The repository is organized as follows:
|
||
- /Gerber: Contains the Gerber files necessary for PCB manufacturing.
|
||
- /BOM: Includes the bill of materials (BOM) listing all components required for assembly.
|
||
- /Documentation: Provides additional documentation, schematics, and datasheets related to Delta-S-M Ver.1.0.

## Cable pinout difference
|
||
|
||
Be carefull, as there is a very important difference in video cable pinout between v0.1, v1.0 and v1.2 and up.
|
||
|
||
**v0.1 and v1.0 boards video pinout:**
|
||
|
||
- 1 - Sync
|
||
- 2 - Red
|
||
- 3 - N/C
|
||
- 4 - Blue
|
||
- 5 - Green
|
||
- 6 - GND
|
||
- 7 - +5V
|
||
|
||
**v1.2 boards video pinout:**
|
||
|
||
- 1 - Sync
|
||
- 2 - GND
|
||
- 3 - Red
|
||
- 4 - Green
|
||
- 5 - Blue
|
||
- 6 - Audio
|
||
- 7 - +5V
|
||
|
||
V1.2 boards are compatible with original Delta-S and Delta-128 and could be connected with their cables.
|
||
|
||
## Making SCART cable
|
||
The best video quality could be achived with SCART cable with RGB mode. Delta S-M is capable of outputting native RGB signal and uses a SCART cable to connect to RGB-capable TVs. The picture below illustrates pinout of both SCART plug and DIN-7 plug.
|
||
|
||
SCART Pinout
|
||
|
||
15 - Red
|
||
11 - Green
|
||
7 - Blue
|
||
20 - Sync
|
||
16 - ADD 180 Ohm resistor between computer and SCART plug and connect it to pin 16 to enable switching to correct RGB mode. Direct +5V could DAMAGE YOUR TV!
