Well, it has been a challenging day for me. My cheap, $8 Radio Shack dual mode (15/30w) soldering iron gave up the ghost - I was about to use it to desolder a leaking capacitor off my t5720 motherboard (one that, I might add, had RoHS solder which makes it a pain to work with) so I can replace it with better caps from Digikey.
Then I realized that I had the iron sitting for at least 7 minutes, but it's not giving out much power/heat - the infrared/laser thermometer that I use to spot check the temp did not show anything above 65 Celsius along the device. Honestly, good riddance. The tip was bent (and really never steady), the cheap plastic handle did not protect against the heat from the element right in front...and the cord was too short and unwieldy. Time to buy a new one - probably a 70 watt Weller digital soldering station so I can get that RoHS garbage off. Amazon is quoting shipping to NYC for mid-May, which is...unfortunate.
The replacement t5720 motherboard I bought had a bad northbridge and rejected all the DDR RAM at my disposal (why does it say my memory bus is 100Mhz when it should be 266, 333 or 400?) and had been sent back for a refund. In the meantime I ordered a replacement for that replacement. The motherboard re-capping for the original broken board was really to be done as a learning exercise.
On other (happier) news, got a bunch of 4GB MicroSD cards that I can use to do some experimental OS installs on the good old Thinkpad 560E. Right now, it's QNX 4.2, OS2 Warp 4, Windows NT 3.51, Windows 95B, Windows 98, and possibly AIX 1.3 for IBM Thinkpads. Trying to see if it's possible to source a cheap PCMCIA-CDROM drive so I can do some CD-based stuff like NT 4.0 or NEXTStep.
