    Well, actually, I do.

    Compaq Deskpro 386

    This is a Compaq Deskpro 386/20 dating from 1989.  Around 1995, I installed a kludge kit on the motherboard which replaced the processor with an 80486.  Memory and I/O speed were unchanged, but the improved architecture of the 80486, including an on-chip floating point unit, roughly doubled the speed at the same clock rate.  I used this machine initially as my main Windows development machine, then from 1996 through 2006 as the HotBits generator machine, eventually retiring it in favour of dual Linux-based machines.  The last time I turned it on, it still worked.  The transformer is a 230/120 volt step-down transformer used because the Compaq and monitor have U.S. power supplies which cannot be switched to the higher voltage, but work fine on 50 Hz power.  The white disc drive is a 3.5 inch Sony floppy drive I installed, replacing one of the two 5.25 inch drives that came with the machine.
