Vintage product in good working order. This Peripheral Expansion Box was a necessity for anyone who wanted to expand the Ti99/4A computer back in the day. They are very rugged but don’t last forever. Holds the memory expansion, RS232 interface (serial and parallel), disk controller and floppy disk drives, etc. Recently, people have been building and selling modern upgrades that fit in the PEB. Example: the TIPI (which uses a Raspberry Pi to provide a virtual disk drive system and allows the TI to function as a WiFi enabled computer). The 110v fan sounds like a jet taking off and the thing weighs a ton. Gotta love it.

Everything worked and not a problem with the expansion box at all.
