Dig out your old BYTE magazines and look for an early Circuit Cellar article about X-Y plotting. In it you will find a picture of a Heathkit IO-105 dual-trace 'scope. Well friends, THAT VERY SAME 'scope can be YOURS! This scope was PERSONALLY owned by Steve Ciarcia and became a fixture at the Circuit Cellar (even has a BEAUTIFUL, PROFESSIONALLY CRAFTED Circuit Cellar mylar sticker adorning the case) - and for an extra $5 I think I can get him to autograph it with an engraving tool ANYWHERE YOU WANT ON THE CASE!!! (sorry - seeing that post about DAK making a comeback has obviously done strange things to my brain) All seriousness aside, I got this from Steve, and it is in very good condition with only one small problem - it immediately blows its fuse whenever you turn it on. I loved Heathkits - they were just my speed - I could follow instructions, measure and cut wire, and I could grab the cool end of a soldering iron over 60% of the time. But without a manual and with no formal or informal training in electronics, to me it's just a boat anchor. I was going to toss it, but if anyone wants it, I can A) bring it to VCF East, or B) have it packed and shipped (it's heavy, bulky and obviously at least the tube itself is breakable). Just to make thing things interesting, anyone who can offer me a book, old computer magazine, Infocom CP/M disk or manual, NEC V-20, anything vaguely CP/M or 8080 / Z-80 /S-100 related, it's yours. No takers - its off to SallyAnn or Good Will (with a note attached stating its fuse-blowing propensity). Decision by the judges is final. Offer good only as long as I feel like it.
