PAL video in the states

Kenbaks in Nova Scotia

by vintagecomputer＠bettercomputing.net

Never know what you'll find googling around. ?I'm kind of curious about this. ?There is a 'museum' (barely.. they have less stuff than I do) in Nova Scotia that has 7 Kenbak-1s. ?I read how they got them.. from a gentleman in South Carolina. ?In his own write up, he said he would only sell them for a 'substantial price'. ?Since I know one sold not too long ago for $30k+.. I'm wondering what the museum paid and why he sold 7 them. ?And how a tiny museum in a tiny province could afford them. ?Kind of a head scratcher! I think this link will give you the story.. the gentleman that sold them asked to have it posted. ?I'm sure this must have been covered at some point in the past.. it's an interesting read though for those lioe me that have never seen it before. ?I didn't expect one Kenbak to be in Canada let alone 7. http://www.computermuseum.20m.com/cgi-bin/framed/3129/KENBAK-1BACKGROUND.htm

Oh, okay, looking at my unit, I see what you mean. Does this threaded fitting have any compatibility with a standard camera lens filter thread? (i.e. Can I buy a standard lens filter and expect it to fit?) --Chuck

What is the most amount of money you've spent on a computer or computer-related item?

by r3trohub＠gmail.com

Hi Everyone! I know this is a bit of a personal question, so please feel free to ignore this email! If you're willing to answer it would also be interesting to know what drove you to spend as much as you did on that particular computer? For me, the most I've spent on a single computer is $2,000 for a Rev 0 Apple II around 3 years ago, I spent that much because I had wanted an original Apple II for so long (not plus or E) and this one was so clean and perfect! I cannot think of a time when I will sell it! Can't wait to hear your answers :) :) _>Andy

> From: Rich Alderson >>> If he had a KA, I would have tracked him down and beaten him to a pulp >>> to lay hands on it > A KA-10 based PDP-10 is the Holy Grail So, how many KA10's _are_ there still in existence? Does anyone know? And I think all the PDP-6's are gone, right? Noel

might be but I do not remember the size! http://www.science-info.net/docs/b-l/BL_Stereozoom.pdf the large articulating arm is the monster we have... it is cool but a desk hop hog see in manual was looking for filter dia specs and do not see... in the manual In a message dated 1/14/2017 12:54:49 P.M.

What is the most amount of money you've spent on a computer or computer-related item?

by sieler＠allegro.com

Interesting question ... brings back good and bad memories :) Probably $5,800 for an HP 3000 Corporate Business System (a 12-processor HP 3000/997). it was a million dollar machine when new. I bought it for $300, paid about $500 for delivery, and $5000 to get the three-phase power installed for it. I reinstalled MPE/iX (the disks had been scrubbed), and discovered that MPE wouldn't boot with more than 10 CPUs active ... due to licensing constraints. All of the HP documentation I could find said that the 3000 version of the hardware was limited to 10 CPUs (the 9000 version, running HP-UX, allowed up to 12). Turns out HP had apparently done an under-the-table sale of a 12-CPU system to someone, and patched (probably one byte of code change) the original copy of the OS to disregard the 10 CPU limit. (Under the table sales, and support, wasn't unusual with HP near the end of the HP 3000's lifetime.) The machine was in a spare room at our office in Cupertino. When we had to move, I donated it to Paul Allen's Living Computers Museum, in Seattle. Stan

Has anyone had experience of using an item like this for soldering and PCB inspection work? https://www.amazon.co.uk/AmScope-Widefield-Binocular-Inspection-Microscope/d p/B005C75IVM/ref=sr_1_fkmr0_1?ie=UTF8 <https://www.amazon.co.uk/AmScope-Widefield-Binocular-Inspection-Microscope/ dp/B005C75IVM/ref=sr_1_fkmr0_1?ie=UTF8&qid=1484294314&sr=8-1-fkmr0&keywords= AmScope+sm-3bx> &qid=1484294314&sr=8-1-fkmr0&keywords=AmScope+sm-3bx At the moment I have one of these: http://www.maplin.co.uk/p/22w-fluorescent-magnifying-craft-lamp-a29ff which I find OK, but sometimes it gets in the way of the soldering iron and it isn't that easy to move it to a position and have it actually stay there.

What is the most prized possession in your collection?

by COURYHOUSE＠aol.com

Alan! Neat! I like this arm you have! I also have an articulating monster B & L arm and it is amazing.... but it takes up space on the desk with a monster base.
