| - **Must have hardware/motherboard parallel port (printer port).** Parallel ports are the pinkie toe of electronics hacking. Youd think they'd be gone by now but nooo, they're still there, hanging around and often necessary for using older software/hardware/schems. I use them a lot for talking to laser and label printers, CPLD/FPGA programmers, bitbanging all sorts of stuff, programming chips via PonyProg, etc.. USB-parallel converters aren't good enough due to the slowness from the USB layer. Hardware parallel ports are just damn handy! | - **Must have hardware/motherboard parallel port (printer port).** Parallel ports are the pinkie toe of electronics hacking.

| - **Must have hardware/motherboard serial port** (COM/Modem port). Two if you can. These are more common than parallel ports. You can use USB-serial ports for most things but sometimes you need the hardware speed of an onboard serial port especially if you're doing some funky bitbanging. | - **Must have hardware/motherboard serial port** (COM/Modem port).

| - **Lots of USB ports.** Both on the outside and on the motherboard. Especially for the shipping computer theres just tons of stuff that needs to plug in - programmers, barcode scanners, scales, backup usb keys, Arduinos. You can also use hubs. | - **Lots of USB ports.** Both on the outside and on the motherboard.

| + | Of course you should recycle what you can. In this case we had already recycled all our hard drives, CD rom drives, etc into other machines! | ||

| - | For the processor we actually went with two options. One was the "AMD Phenom II X4 810 2.6GHz 4 x 512KB L2 Cache 4MB L3 Cache Socket AM3" ($150, this was for my personal workstation) and the other was the "AMD Sempron 140 Sargas 2.7GHz 1MB L2 Cache Socket AM3 45W" ($40, for the shipping/programming workstation). The shuttle cant power more than 95W so dont try to overdo it or you will get heat problems! | + | For the processor we actually went with two options.

| - | I rounded up because I didnt include shipping. The keyboards and monitors were recycled. We've been happy with this set up, hopefully it will be useful for someone :) | + | Which means that we met the budget of $500 (averaged together) |
