Texas Instruments PHROM Emulator Board

This is the original board used by Acorn to develop the Kenneth Kendal speech ROM for use with the BBC Micro. The four EPROMs on the upper part of the board contain the development version of the PHROM data which was subsequently put into production.

The board can be connected to a BBC computer via the PHROM interconnect cable. The second cable connects to the speech connector.

The board has recently been repaired and is in good working order. It was kindly donated by Simon Inns.
