Component Specifications

Warning: This documentation is incomplete and may not cover all current ALX PC features.

Screens

EGP Screen

A screen based on Wiremod EGP that displays graphics rendered directly by Expression2.

Digital Screen

Supports displaying images up to 512×512 pixels. Images larger than 512×512 are automatically resized to fit the screen.

Quad Digital Screen

A screen device that uses four Digital Screens to display images up to 1024×1024 pixels.

ZGPU Screen Renderer

A beta image renderer for Wiremod ZGPU.
It uses a bridge between Expression 2 and ZASM to render images through a ZASM program, with support for images up to 512×512 pixels.

See the ZGPU Screen Renderer source if interested.

Storage

Wire Dupable HDD

• Bytes per sector: 4 (32-bit)
• Maximum bank size: 1 MB
• Maximum bank count: 4 (can be extended)

Wire EEPROM HDD

• Bytes per sector: 4 (32-bit)
• Maximum bank size: 1 MB
• Maximum bank count: 4 (strict multiplayer limit)

EEPROM Limitations, Warnings & Differences

Limitation: Only ONE EEPROM HDD can be spawned per player! Each HDD Bank uses a unique DriveID (maximum of 4 allowed in multiplayer).

Warning!

EEPROM writes data directly to the server, which is slow (~34 minutes to write 1 MB). If the server crashes during this process, data corruption will occur. To ensure data is safely written, remove the entire EEPROM HDD and respawn it. This forces a data flush to the server disk.

Difference between regular DHDD and EEPROM HDD:

• EEPROM stores data on the server inside garrysmod\data\wireflash.
• EEPROM data is persistent on the SERVER and remains intact even after a respawn.
• DHDDs are dupable (can be saved and pasted with Advanced Duplicator 2).

HDD Controller

• Maximum connected HDDs on PCI-E bus: 4 (can be extended by modifying the code)
• Maximum connected HDDs on PCI bus: 2 (can be extended by modifying the code)

CD Drive

• Supports virtual Wiremod discs from Mini-CD (14 KB) to BDXL (1724 KB).
• Supports dial-side discs.
• Supports book type changing.
