• Access to the RetroStore
• FreHD emulation
• Access to files mounted on a SMB share
• Access to remote servers via TCP

The MISE (Model I System Expander) is an add-on device for the vintage Radio Shack TRS-80 Model I microcomputer. It connects to the buffered expansion port on the Expansion Interface or directly to the Model I keyboard, and provides these benefits:
Direct-booting solid state hard disks on Compact Flash, with LDOS-5.3.1 preloaded. No boot floppy or ROM modification is required. Each bootable image can hold up to 64MB, and multiple images on CF cards are supported. That’s a whole lot of space for programs mostly written for 16KB RAM. Dual CF cards can be used for additional storage or easy backup.
10/100 Mbps wired Ethernet connection (up to 8 active IP sockets) with included software: FTP and TFTP servers, FTP client, DHCP client, SNTP client, Telnet client, and Telnet server and DNS client demo programs. Globally-unique MAC address (EUI) provided. Easily move files to and from your TRS-80! Drag and drop!
Real-time clock/calendar with battery backup, compatible with the vintage Alpha Products Newclock-80. Battery backup means the date and time will be accurate and automatically set at every system boot.
Crystal-clear SVGA display output for an 800×600 @ 60Hz monitor, no software required. One-of-eight selectable foreground, background, and border colors. Emulation of the vintage high-resolution PCG-80 and 80-Grafix devices. 80-column text display mode available. Using the VGA display is optional; you can still use the original CRT monitor if you prefer, or you can even use both at the same time.
ROM extension including drivers for the hard disks, real-time-clock, and double-density floppy adapter, if you have one. None of these drivers need consume precious high memory.
Joystick port for Atari 2600 compatible joysticks. Works with most vintage Model I games.
256-byte general-purpose Flash EEPROM for persistent storage.
