    I have a 1973 4004-based Intellec 4/40, (S.N. 89) in Intel blue that I’m considering selling online. Finding this unit was the classic “’53 Corvette in the barn” scenario. I know that it hasn’t been used since the Intellec 8 came out in late ’73 and I have never so much as plugged it in since acquiring it about ten years ago. It is in great shape, although shotgunning all the caps is probably the wise thing to do.

    My last attempt to sell the box a few years ago generated a flurry of donation requests from various online computer “museums”. One collector even went out on a limb and offered me $100 for it, with the warning that any attempt to hold out for more would result in the immediate withdrawal of his generous offer! I did not reply to his offer. I can assure you that I am a card-carrying capitalist, I know what I have and that I will be looking to get top dollar for it. I make no apologies for that. Anybody interested in making a serious offer before I list it on eBay?

    1. Hi Franklin,

      Some tips if you do post on eBay.

      Provide plenty of photos of the inside as well as the outside. Buyers will want to know all the components they are getting.
      Describe how you will pack and ship. Some buyers are hesitant to purchase old systems through eBay because a poor packing job can quickly make them worthless.
      Give as much history on the system as you can. It looks like you have a low serial number. Do you know who the original owner was?

      Maybe you are an old hand at selling vintage systems on eBay and already know all this stuff, but I thought it worthwhile to point out.

    Thanks for the advice. I have a large padded Anvil case that was originally designed to ship a delicate video camera control unit. The INTELLEC fits snugly into the foam cavity.

    I have a full set of photos from the last attempt at selling the unit. Every card has been photographed, back and front. The unit came to me from the estate of a deceased engineer who spent his entire career with a well-known global technology firm. His wife remembered him setting up the unit at home on her kitchen table during the period when the Watergate Hearings were being televised live. (She liked the “little blinking red lights”.) If I recall correctly, those hearings were broadcast during the Spring and Summer of 1974, culminating in Nixon’s resignation in August. She also mentioned that he only used the unit for a short time before getting a “better” unit with more lights. Perhaps he switched to an INTELLEC 8?

    One side note, I also received four very early HP 9810A desktop computers from the estate, probably older than the Intel unit. Sadly, they ended up in the dumpster at the TV station where I work when I took a leave of absence to go back to school. Luckily, I kept the INTELLEC at home.
