Ah! Alas no 2716. I do have a 2732 and I found 2 x IM6654 512x8 :shock:

Let me, or Daniel, know if you want the 2732.

No, but thanks for looking! I need the 2716 part. It's for an existing circuit.. but in the meantime I have used a 2816 EEPROM but it only has a retention life of 10 years.

A 2732 should work if you just double up the content and tie pin 23 to ground? http://www.z80.info/gfx/eprom.gif

Yes, I have quite a number of them, no idea what they are worth, postage will be a few quid at least from NL to UK. If interested let me know how many you might want (I'd guess you could use more than 1, better for testing, right?)...

Bit late but did you get sorted Jon? I have a few here, HN462716G (RS 309-379), which are probably new or very little used - I can erase and test program a couple if you're still wanting. Postage only so I guess a pound or two First Class large letter, would be early next week for posting.... 8)

This goes for anyone else too, just holler !
