You could do it pretty blindly with an excellent chance of success IF you're good at removing DIPs from circuit boards. Since those were single-sided boards you'll have to be careful about the pads lifting, in which case simply clip all of the package leads (14/16) and then remove each separately. Install a low-profile socket (for next time ...). I've made many reparis and mods to 8/L's over the years by this method without any problems. Also, since the circuitry is so simple on a card, you can easily do fault analysis in single-step mode from the backplane (wire-wrap) alone -- no extender board is required and all you need is a level indicator (logic low/high) and a latch (did a pulse pass?). A nice environment to learn hardware repair ... The analog components (i.e. memory drivers and sensors) are another matter entirely ... paul Received: from AI.AI.MIT.EDU (CHAOS 3130) by MC.LCS.MIT.EDU 27 Oct 89 10:04:53 EDT Date: Fri, 27 Oct 89 10:08:48 EDT From: "Robert E.
