  1. How did you run an Emissions Diagnostic in the 80's?

    In my last article I discussed AMC's CeC fuel feedback and emissions control system and specifically how to depot it for the purpose of reverse engineering. This consisted of one Intel MCS-48 microcontroller and a dozen inputs and outputs. This was pretty normal for the time and other automotive manufacturers were using similar designs, if not borrowing from one another. The problem with going this route however was that the system was closed-minded. There was no OBD2 and there was also no OBD1. ...
  2. Depotting an 80's MCU from Ford...for AMC

    Mention fuel and emissions control to people who lived through the 70's and early 80's with a car and for some reason the music of CCR and the sound of helicopters start going through their heads as if the Malaise Era was as traumatic to them as Vietnam might of been.
    Basically in that period the ability to run an engine loud and rich was being clamped down on to deal with smog and fuel shortages. Initially it was devices such as anemic carburetors, smog pumps, the Exhaust Gas Recirculation ...

  3. ITT PowerSave 500 - UPS on an ISA card

    This is actually a board that was on loan to me for the last week while I removed the batteries. It's a 230w rated UPS with a 15 minute reserve capacity that's designed to plug INSIDE YOUR PC and connects in parallel with your power supply. A little bit of software shuts the system down gracefully when it is engaged, however makes the system immune to accidental cord pulling or power switch flipping, which are probably the two last things you could do to idiot-proof a server.

  4. Obtaining a Forgotten Login on an IBM System/36




    This blog post comes from the issue where you may end up with a System/36 where just the administrator or all of the user accounts and passwords have been forgotten. This article has been created to help de-obfuscate an existing procedure posted about 15 years ago here on Usenet. The purpose of redoing this procedure is to be a bit friendlier on those folks ...

  5. The sleeper three-button Logitech mouse

    Now normally I spend a lot of time slagging ANYONE who dares use a keyboard with anything but their original machine and frankly the same should apply to mice as well, right?
    Well yes there are a large number of notable examples of mice that really only worked with specific machines both electronically and asthetically. One example I can come up with is the Hawley mouse. It is absolutely revolting on terms of ergonomics but it just seems like the kind of thing the "hip" tech crowd ...
