What's this, any ideas ?
Digging about in an old drawer looking for a plug today I found this, I don't remember where it came from but it is 28 Pin DIL chip in a socket, maybe to protect the pins and it has the handy Graphics label on the top suggesting maybe it was an upgrade for an early computer..
Any ideas anyone

Re: What's this, any ideas ?
That looks like a Sideways ROM for the BBC Micro. The 'Graphics' label reminds me of either Computer Concepts or Acornsoft as the publisher. I think they both did graphics extension ROMs but I could be wrong. It probably dates from about 1983-1984.
It'll be a 27128 (or 2764) under the label. Putting it in a BBC Micro or reading it in an EPROM programmer would soon identify exactly what's in it. Chris

I can confirm Chris is exactly right.

Judging by the style of the box art it could be the Computer Concepts version.
