Re: 27C256 programmer
I am about to find out. I borrowed his programmer but will practice on some
other chips first. There is now a better download of a manual. It is not a

Re: 27C256 programmer

Re: E4406 Synthetizer trouble
Yep, Avago Technologies spun off from Agilent in 2005 (IIRC), which spun off from HP in 1999, IIRC. And depending on how you look at it, Avago bought Broadcom or Broadcom bought Avago in 2016.

Re: 27C256 programmer
I second Dave Hills recommendation. The GQ-4X is USB based, works on Windows 10 and works for older Eproms and PICs as well. Never had a problem with it.
