Looking for early Blitter chip

[ijor]

With my ongoing ST chipset research, I would like to perform some tests on early Blitter revisions. I am specifically interested in Blitter chips made by IST (Innovative Silicon Technology) or ST (SGS Thomson's). They usually have an early 88 datecode. I will add some pictures later.

Shipping is to USA. I will pay, of course, all full shipping costs, and will also pay a reasonable amount for the chip as well.

Please contact me by PM if you have such an early Blitter chip and are willing to ship it to USA.

Thanks

I responded at Atari-Forum as well, but here is what I have:

Okay, maybe this is closer?

PS If this is still not it, can someone post a picture of
the Blitter chip so I'll know what I'm looking for? Thanks.

National blitter. Basically the ones I have also.
