by Jeffrey Brace 29 Jan '16

29 Jan '16

I was at the InfoAge meeting tonight and scouted out the area. There is *some* snow at the back entrance to 9032-A. Not significant. I feel like most of it will be gone by Saturday as there will be above freezing temperatures Thursday and Friday. So what's everyone working on? Bringing? Me: Commodore 64 and Commodore 1541 repair. Various broken 1541, at least 2 working 1541, soldering iron, 1541 speed controller, and if I can find a disk cleaner kit. You: ?

We'll open the new museum room (same as where we held Festivus last month) for anyone who wants to sleep over Saturday night. It has much better heating than in the workshop room. As usual, bring your air mattresses, sleeping bags, etc. .... no shower facilities, so bring deodorant too. :)

So I did a little road trip out to Cincinnati to pick up a couple dozen IBM Twinax terminals; got home last night. In the pile was a pristine HP 2645 terminal, complete with keyboard. "How'd that get in there?" the guy asked. It's mine now! B-) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
