About the Case:

This is a custom designed case (ORIGINAL by COREi64.com), for the Texas Instruments TI99/4A 32K Sidecar memory expander (not included).  The case is available with the activity indicator more conveniently and visibly located on the side of the, or through the lid.  Your choice.  It is available in many different colors.  The case is held closed with four 16m black oxide screws threaded into brass heatsets inset into the lid.  The lid includes a block-off plate for the data pass-through port.  If you're not using it, you can keep it safely blocked off.

The case shown in the photos is just one of many different configurations you may choose from.  The case shown is styled after the original Texas Instruments TI99/4A Black and Silver case.  Available in many colors.

If you choose the "TI Color Scheme (Grey top/Black Bottom)" then any choice selected under the color option will be ignored.
