Retro Computing

Hardware I've collected and kept running over the years. From Atari ST and Amiga to MiSTer FPGA and DOS environments.

đŸ–Ĩī¸ The Mega ST Fleet

Three Mega ST 4 machines and a Mega ST 2, each with a clearly defined role from heirloom to workstation.

🎮 Mega ST 4 Low

The bargain-bin Mega ST 4 rebuilt as a LowRes demo and games machine with Cloudy/Storm ST, Gotek, UltraSatan and more.

đŸ–Ĩī¸ Mega ST 4 High

The high-end workstation with MonSTerBoard, ET4000, NetUSBee, Eiffel and STPSU, running Geneva.

🔧 Mega ST 2

The spare and test machine for the rest of the fleet.

đŸ›ī¸ Heirloom Mega ST 4

My father's original Mega ST 4, kept factory-original as a baseline reference.

🌀 Storm ST & Cloudy ST

Adding 8 MB Alt-RAM and flashable TOS to the Mega ST, switching between EmuTOS and iTOS 1.04.

🧠 MonSTerBoard

How the MonSTerBoard turns the Mega ST 4 'High' into a workstation with 8 MB TT-RAM, dual IDE and flashable TOS.

📖 TOS Explained

A short explanation of TOS, the operating system behind every Atari ST, and the versions that matter today.

💾 Gotek Floppy Emulator

Replacing floppy drives with cheap Gotek emulators and HxC firmware, using USB stick disk images on the Mega ST 4 'Low'.

đŸ’Ŋ UltraSatan

Giving the Mega ST 4 'Low' a real ACSI hard disk on an SD card with the UltraSatan Mini from Lotharek.

đŸ’Ŋ ACSI2STM

An open-source ACSI to SD card hard drive emulator for the Atari ST. Bought, not yet in use.

đŸ’ŗ SidecarTridge Multi-device

An apps platform in a cartridge, adding Wi-Fi, ROM emulation and floppy/hard-disk images to the Mega ST 4 'Low'.

âŒ¨ī¸ Eiffel Interface

Connecting a PS/2 keyboard, mouse and joysticks to the Mega ST 4 'High' with the Eiffel adapter.

âŒ¨ī¸ Eiffel Pico USB

The modern USB-based Eiffel successor, bringing USB keyboard, mouse and joysticks to the Mega ST. Configured, not yet installed.

đŸ–ąī¸ mouSTer

Connecting a modern USB mouse to the Mega ST 4 'Low' with the mouSTer DB-9 adapter.

đŸ–ąī¸ Laser Mouse

Converting an original Atari STM-1 mouse to a modern laser sensor with the Atari mouse laser board.

đŸ“ē Atari to VGA

Getting the Mega ST onto modern VGA monitors with three RGB-to-VGA adapters: MCSWITCH, a self-build and an ST2VGA Enhanced.

đŸ“ē Monitor Compatibility

The 15kHz problem explained, and which modern monitor panels actually cooperate with Atari colour modes.

⚡ ET4000 in the Mega ST

Adding higher resolutions to the Mega ST 4 'High' via a STGA adapter and an ET4000 card, and what it took to get it working.

🔌 STPSU

Replacing the aging Mega ST 4 'High' power supply with a modern STPSU for clean, stable power, especially for the ET4000.

🌐 NetUSBee

Real internet via STinG and a USB port for FAT16 data exchange with Windows on the Mega ST 4 'High'.

🔌 Wi-Fi Modem & BBS

Dialing into telnet bulletin board systems from the Mega ST 4 'Low' using dhansel's WifiModem and terminal software.

🧩 MiSTery Core on MIST

Cloning the Low's SD card to the MIST FPGA for direct SD access, five configurations and a backup plan if the real Mega ST breaks.
