• Made replacement for lost W070 teletype interface card & cable.
• Attempted to fix W300. Due to previous evidence of temperature improving the problem tried heating sufficient to reflow solder inside assuming cracked solder joint was the problem. Appeared to fix all except one. Some cracking of delay lines from heat. Last delay line not needed to bypassed with wire.
