content: Today I went to the surplus place. I picked up several things. One of them being a Tek 1240 Logic Analyzer for $50, works a treat (near as I can tell). The other was a really good buy I wasn't expecting. It turned out to be a Verizon FIOS node.Inside was a 120V to 48V power supply, a 12V 7AH lead-acid battery (that I hope can still hold a charge, it's not that old), a fiber tranceiver, and a whole bunch of other cool stuff. I'll post a photo of the board when I get a chance. Worth $15, for sure.If that battery turns out to be good, that'll be enough to power my iPad under full load for quite a while.

content: I have a surplus shop nearby but it only really contains high power electrical components. (bus capacitors, gigantic relays, igbt bricks, etc) Of which I have no interest.I did buy a 3700 mfd 400v mallory bus capacitor. I made a little charge pump for that sucker and showed my physics class what 296 joules (two cokes) looks like. That was a really fun day.

content: Alright, I didn't get pics of the whole assembly, but I got pics of the main board, which I'm sure you all will still find really interesting. It uses a broadcom chipset, you can see the fiber transceiver to the lower right, a set of odd looking fuses to the left accompanied by four relays, and a few other interesting and rather odd stuff. Kinda cool.What struck me about it was how servicable it was. Everything just popped off.

content: Nice!My local surplus place sells at near or over retail.A 56kbps ISA modem card for $24.95? Really? In one bin they were selling micro drill bits for pcbs for $0.50 each. Not bad I thought until I looked and saw they were all broken! It was someone's garbage ffs.

content: Some of the deals aren't so good, but they'll negotiate with regulars, and apparently I'm a regular.And some are REALLY good.

content: I used to live about 2 miles away from a store like that (although I never saw scopes there)They used to have 68K Macs for $10 each and a variety of just random computers and cards that were really old.They had a computer museum section in one corner with things like old commodores, kaypro portables, you name it.I picked up an Nvidia FX5200 card for $5 in the junk bin. It was marked DOA. I had a hunch that the firmware had gotten corrupted so I put together a floppy with an autoexec file to reflash the firmware without needing a keyboard and sure enough the card came back to life!

content: Surplus places are great.This one has a Macintosh Plus, last I checked. I'm not buying it because I have enough crap.
