 |
|
I bought a P8048 last week.
The marking is
P8048 0148
7914
ESM-410B
(C) Intel '77
The bottom says "7636 USA"
Will it be the ES chip?
Thanks for your info. |

I can make the high profit for selling it if it's ES chip. Now I may suffer the loss.  |

ESM-4108 will be the marking for the OEM that ordered it, its a MaskROM version of the MCS-48 (in this case MaskROM 0148)
Whats the date on the bottom?
