   - **Case**: Hammond [1598C], in your choice of colour. The case should include mounting screws, feet and two un-cut end panels.
   - **End panels**: Cut the panels supplied with the case according to [the drawing](./endpanels/endpanels.dxf). There is a PDF version in the [Neotron-32 Release Area].
-  - **SD Card**: Any full-size SD or SDHC card should work. Tested with Sandisk 8GB microSD cards in a micro-to-full-size adaptor, formatted with a single FAT32 partition.

   - **Monitor**: You will need monitor with 15-pin VGA input that can handle 800x600 resolution @ 60 Hz. Most higher resolution LCD panels will up-scale the image, but the quality of the scaling may not be ideal. A CRT will give a better image, but you may need to wind up the contrast and brightness to get a workable picture. An old 800x600 native resolution LCD would be ideal.
   - **Power Supply**: You need a standard mobile phone charger or other USB power source, and a standard USB A to B cable (like you would use for a USB printer).
   - **Ribbon cables**: The DB25 Parallel Port and DE9 RS-232 Serial port require a 2.54mm pin header to D-Sub ribbon cable. You can scavenge them from an old PC, or buy them new from Amazon, eBay or AliExpress for a few UK pounds.

   - **MIDI**: If you want to hook up a MIDI Synthesiser like a Roland MT-32, or a MIDI Keyboard, you just need standard 5-pin DIN MIDI cables. USB MIDI devices are not supported.
   - **USB**: The Tiva-C Launchpad has a USB micro-AB connector into which you can plug a Raspberry Pi Zero compatible micro-A to full-size A adaptor. There is no USB support in firmware yet, and the board can only supply a limited amount of current, so don't expect your mobile phone to charge.
