Heath H-11 line time clock question
by Richard Cini 19 Apr '16

19 Apr '16

All — I just hit on an anomaly with my H-11 so I wondered if there was anyone on-list with experience with the H-11, although it crosses-over to DEC. In short, I added an Emulex SCSI card and SCSI2SD to my H-11 so I could run RT-11. The TU58 emulator was way too slow. RT-11 won’t boot with the LTC enabled, and the Emulex manual specifically says it should be disabled at the CPU card. But, I want to run Kermit (to enable easier file transfers rather than dd’ing a new image to the SCSI2SD each time), and Kermit for the PDP-11 requires the LTC. The H-11 comes in two versions – one with an LTC switch and one without. Mine doesn’t have the switch, but one was added, performing the same function electrically (grounding the base of the transistor driver to the BEVENT signal). If I put a counter on the BEVENT pin, I get 60Hz with it enabled and 150Hz with it disabled. This is the anomaly I wanted to check out with any other H-11 owners. Alternatively, if anyone knows of a file transfer program for RT-11 (SJ, FB monitors only) then maybe that’s an option. I’ve seen an XMODEM program but it uses TSX. Thanks!

Distribution systems should be serviced per NETA guidelines - that's why power is cheaper per Kh / hr when purchased at 13.2 kv. The customer is paying for the purchase and upkeep of the distribution system, not the utility company .

VCF East XI.........
by Dan Roganti 19 Apr '16

19 Apr '16

Just wanted say its been another great event. Wouldn't miss it for the world. There were great keynote speakers, so many good classes, as well as great exhibits this year. Something to enjoy in all corners of those event. In addition, it's always nice to see familiar faces again and I'm happy to see new ones. This is how this group stays vibrant and alive. This had become my annual pilgrimage for a decade and hope I can for another decade. Kudos to the VCF board, Evan, Corey and Jeff for masterminding another year with an event full of activities. I know they put up with a lot of crap from us, including myself :) But I think it's all for the betterment of this group. And a special thanks to the 'boots-on-the-ground' volunteers that helped make this possible.

Ted Nelson mentioned a book in his talk, I made a mental note to remember "Posiplex" but I don't think that's right...anyone remember the book he referred to, other than Geeks Bearing Gifts?

I had a blast as well. I'll definitely be back next year! If someone took a picture of my Lisa exhibit could you share it with me? I realized after I started tearing it down I didn't take one!

Ethan's pictures from event
by Ethan 19 Apr '16

I dumped my camera pics onto flickr from VCF East. I got some exhibits, I missed some of them because there were large crowds around them at the time I was remembering to take pictures. Pics taken with a Elph camera not cell phone. Probably a few not worth keeping, but the internet is slow. Nothing like working in the buildings that very likely have more internet bandwidth than any place on the east coast ... and the wifi is sluggish. Grrr. https://www.flickr.com/photos/ethanotoole/albums/72157667183646172 Enjoy!@#

VCF East XI.........

http://www.retrotechnology.com/vcfe11/vcfe_11.html Edited photos of the event, rough cut. Please contact me if there are errors or corrections. I'm glad to permit other VCF-E attendees to use these photos, please send me links to your use of them, please return the favor. I'll have more to say of course; I enjoyed the event and thanks to all my friends and colleagues, new and old. I was particularly happy about S-100 participation by exhibitors, speakers, and in sales. That's a primary mission of mine. Vintage computing of all flavors was represented, from core and drum memory to 1990's tech. Repair to new designs were represented too. The event was more than I could cover and experience.
