AMD 486dx4-120 (no, not overclocked), Vesa-Isa-Pci motherboard (all timings are now slowest possible), 20M ram (Siemens 60ns :), noname NCR 53c810 SCSI card, two hard drives: Conner <something> reporting as SUN0.535G :), Quantum Maverik (BTW, there are two swap partitions on both disks, 25M each), noname IDE/multiIO card with Quantum Caviar 200M disk and Toshiba ATAPI cd attached, two serial/one parallel card (yes, there are: mouse, modem, AD terminal and UPS), noname ESS1688-based sound card with wavetable daughterboard and MIDI keyboard on it's MIDI bus.
BTW, there is some other strange thing WRT my hardware (or kernel?). Once I actively worked with A/D terminal, I've noticed very misterious thing. When /dev/ttyS? is open (getty's running) and terminal is turned off, there are interrupts on that port (at least, as it's reported in /proc/interrupts) running at rate ~3000/sec. Later I shut down getty and forgot about that. Even later, when I attached MIDI keyboard, I saw the same thing! When sound driver is loaded, but keyboard is turned off, there are some 3000 interrupts/sec on MPU line!! What a mess...
{ For those who don't know. Most sound cards these days have MPU-401 dumb mode - compatible interface, which is in fact current loop UART, on them. MIDI keyboard is serial divice capable to send bytes to this UART. Wavetable daughterboard is hooked to the same interface (it has bus topology) as a receiver. }

Grrrhm... :)
