Does crooked chip markings effect the collectability a lot? I don't usually see it this bad but they are genuine.

Not rare, but not super common, I have seen some that are even double marked, the printing machine just gets out of wack from time to time

Its one of the reasons they moved to laser etching

Thanks for the replies. It's part of a kit and I'm surprise that a B4702A and a B1702A was mixed together. I guess they used whateveer they had.

One more question. Does the B4702A have an S-Spec number on it? I do apologize for the newbie question but I'm new to vintage chips but not to vintage computers. What exactly is an S-Spec number and doesn't that apply to CPU's only?

Thanks in advance.

No it can be on anything, intel used it originally to denote a device thats specs were DIFFERENT form normal in some way. Perhaps more or less testings, diff voltage or timing, or just a customer specific parameter.

So some parts didnt have them, and others did

In the late 1980s they started moving most everything ((non-memory) to having a sspec
