 |
|
I picked up a few old boards from an HP 2100a computer that looks to be about 1973/74. One of the boards has some white ceramic ROMs + 1xHP grey trace white ceramic ROM. Pic is attached.
Does anyone know much about these - are they collectible? |

The whites have Motorola logo and maybe the part numbers (SCM642AL) can be looked up.
The Fairchild "Brownies" have gold centers!  |
