Subject: [N8VEM-S100:5575] Re: SCC and Z80/8086 monitor
Based on some favorable reviews, and in need of another serial port and the lure of a really high-speed USB connection, I acquired one version 03 Serial I/O board. Then I set out to locate the parts. 8255 located in my parts bin. But no Z8530 although I have just about everything else. So I searched Jameco and a couple other suppliers, but it seems no one has the Z8530. Two questions: 1) can the Z8531 be used in place of the Z8530 (seems like it lacks the synchronous operation), and 2) has anyone bought Z8530 recently, and from where?
Hi Bob --
Try Unicorn Electronics (www.unicornelectronics.com) or Futurlec (www.futurlec.com). Unicorn has them for $3 or $3.50. I think Futurlec had them, but haven't looked lately. I'm surprised that Jameco didn't have them. That's where I got mine.
