Bob Frankston emailed me to point out that he and I are giving talks at the same this during HOPE this Saturday. World-changing programmer vs. lowly historian/journalist... I'd rather listen to him. :)

About 10 visitors today. It seems that during the summer many of the visitors are from out of state. Interested kids, so it's all good. Bill I. stopped by to copy some documentation for the TR-20 EAI Analog machine. == Jeff Brace

I don’t think a train woul work. Someone would have to get it to the train station (Sridhar can't due to this work schedule). Also while the computer is not large, it is quite heavy! Basically it's an S-100 chassis with the screen and floppy drive all integrated. However I am chasing some car leads... stay tuned.

> I take an Amtrak train that passes through Poughkeepsie between 7 and 8 am on Thursday on my way to NYC. Amtrak also offers a Package Express service, if it comes to that. Someone could also take Metro North into Poughkeepsie, pick it up, and ride back. It's not that big of a machine. Thanks, Jonathan

Urgent!! Z-100 update
by Evan Koblentz 20 Jul '16

Sridhar got the computer from Ian, so now it is in Poughkeepsie, no longer Schenectady. WE MUST GET IT TO HOPE THIS WEEKEND. It could be brought to my place in northern NJ or directly to the show this weekend, but getting it there is not optional. I am under no-driving orders from my dr. so we need someone else to do this. Someone please step up!!

Perhaps I am remembering a shutdown script? But I've always done "sync;sync;halt", and I distinctly remember a buffer flush in the halt program. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Admittedly, it's been over 30 years so my memory may be faulty, but I seem to remember that in 6th Edition there wasn't a shutdown program or script that unmounted the root file system. As I recall, the documentation specified that sync should be run before hitting the halt swtich on the 11. > I myself use two. =) Me too BLS
