Anyone have a bunch of 27C64 Eproms they are willing to sell? Or even a few, please contact me. Building up some cartridges and I just need the eproms. Thanks.
From Where China? And what is your definition of cheap? Per unit? Id consider any alternative.Why don't you use 28c64 eeproms? They are cheaper and there are plenty on ebay, even from US sellers...
I get them from China, yes, but it takes a few weeks. If you want them right away, here is an example:From Where China? And what is your definition of cheap? Per unit? Id consider any alternative.
Yeah I am not against buying from china on certain projects. $7.10 each is too much for me if I can go cheaper I would. China would be a better bet.I get them from China, yes, but it takes a few weeks. If you want them right away, here is an example:

Is this cheap enough?
From China you can probably get them at 50c/each.
It's not 7.10 each. If you buy multiple items the shipping charge is more or less the same... 6 for 18.45.Yeah I am not against buying from china on certain projects. $7.10 each is too much for me if I can go cheaper I would. China would be a better bet.
Oh I know and I for one am all for this. I purchased two sound chips for my Mac color classic from one of those resellers. I was a fair price, it was my only option, and they both worked fine. Selling our junk back to us is capitalism at its best.... I wonder if the irony is lost to the Chinese?Hi,
Something some people don't realize is that we sent millions of tons of old electronics including thousands of vintage computers to China to be recycled. Many smart people in China pulled them apart for the boards, the chips, the cables etc. and now you can buy them on eBay.

Hi,I personally think they just recycled everything for their machinery, and since they have upgraded much of their infrastructure since the 90s, these parts are seeing daylight as there is no use for them, and viable to the hobby market.
Almost surely Shenzen.Hi,
A few years ago a friend of mine was in the main electronics marketplace in China (I forget the name of the city), and he talked to a bunch of small vendors there and they said when we send our junk electronics to China, they grab as much as they can afford by the pound and pull all the components off to sell to people on eBay. Some of these shops had hundreds of hard to find vintage chips.

sst27sf512 should suit your needs.Is there a drop-in 28C (or similar flash) replacement for the 27C512? 28C512 doesn't look pin-compatible. I go through a lot of them and source NOS UV-erasable 27C512's from China (this seller) - I've had good luck with those. Other chips like the 2732's are hit or miss.

Yeah, I'm in the same boat. But at least they are there.Wow, thank you. Very good to know, but looking at prices they're going for 2-3x more that what I'm paying for the 27C512's.. Guess I'll stick with those as long as I can but it's good to know there are alternatives.
