A las lÃneas de tierra (49) y /reset (41) del puerto de expansión. Con preinstalación para botón de pausa (a la lÃnea de /wait, 39).
This is what makes the buttons produce noise. First introduced in the 1980s and still in use since then.
Found lurking in a Dept of Transport truck on the corner of Winston Ave/Edward St in Melrose Park. It was only a year old at the time but I got kind permission to have this in my collection!

Trying out extension tubes to do some macro shots of some knackered RAM that I had to remove from my PC.
A while back, I spilled a glass of water all over Gimli, my 17" Powerbook. Today I finally got around to salvaging the hard drive out of it, and low and behold, there's some pretty fried chips.
New Crucial 64GB 6gbps SSD based on Marvell controller. I got this drive to replace a database drive which I was previously hosting on a sandforce SSD (which corrupted my data, yay). I suppose switching to a new drive is an even bigger risk, but I think I'll set up some good backups :)
(Yes, of course I have to take it apart and take pictures before using it)
The SID-SHIELD is a prototype board developed by A Fox Consulting & Design to allow an Arduino-based system to utilize the MOS Technologies 6581/8580 SID chips. It is shown here mounted on an Arduino Uno board.
It uses a MCP23017 I2C 16-bit I/O expander to drive the SID chip's address and data lines and a MC34119 1/4 watt audio amplifier to drive a speaker.
The board uses only 4 of the Arduino's I/O lines: two for the I2C communications, and digital pins 8 and 9 for ~WR and clock signals.
It is strongly recommended that only a 9V DC power supply is used to power the Arduino when using the SID-SHIELD.
