ATPL Solderless Sideways ROM/RAM Board for the BBC micro model B

Details:

* Tested and working

* A new connector for the wires from the board to S21 South have been added as they were missing

* Riser pins are straight / undamaged on the IC73 although I have added an addition turned pin socket to protect the pins

* Two of the pins have been repaired on the IC51 and again I have added an addition turned pin socket to protect the pins

Note: The addition of the turned pin sockets does raise the board every so slightly creating a slightly more snug fit than was the case previously!

Includes:

* Board

* Copy of the original instructions

* 2x HM6264LP-15 RAM chips fitted to sockets 15a / b for the Sideways RAM

Fitting:

* Remove your OS chip in IC51 and D7002C chip in IC73

* Add these to the correct sockets on the board

* Remove the jumper on S21 South link

* Fit the flying lead fitment is to S21 south - blue wire to the West

* Position the board over IC51 and IC73 making sure that the pins align with the sockets and then gently press down

Notes:

* Includes only the ROMs shown on the first and second photos (the others were added to show that all sockets work as intended)

* I accept no responsibility if you damage the board or your BBC when fitting this

* Free fitting if you bring your BBC to me, Drighlington near Leeds
