My Kenbak is coming along. I spent almost the entire weekend making some parts on my (Sherline) mini-mill.
I had two very nice small fans that I'd pulled from surplus equipment, and some 1/8" x 3" wide aluminum plate stock, so I cobbled together adapter plates to mount in in the Kenbak. The fan near the memory blows in, and the other blows out. I also made a u-channel bar to hold all the buttons. I tried attaching it with velcro, but that was too thick, so I settled for some vinyl super-strength double-sided tape. I powered up the unit without chips, and nothing blew up. So far so good! I'm including pictures. One shows an alternative 60 Watt power supply I have that I might switch to eventually. It will leave the motherboard completely visible. Astute observers will note that I've reversed my back panel. It is a long, rather embarrassing saga, but all turned out well -- I bet I have the only Kenbak clone signed signed TWICE by John Blakenbaker. (Thanks John!) I'm having a great time, obviously. Thanks, Grant! tonyv Last edited by tonyv; 12-10-2007 at 05:12 PM. |

I had this in my (rather large) supply of surplus robot parts.
It says "EOS VLT60-3000" Ooops. No -5 volts. Just +5, +12, and -12 (just what we need). Unfortunately, it looks like this one is no longer made. Last edited by tonyv; 12-10-2007 at 09:00 PM. |

Well, supposedly
http://www.eoscorp.com but that doesn't seem to work anymore. Ah HA! They were purchased in 2001 by Celetron: http://www.celetron.com Oops! that doesn't work either.... Another pdf: http://www.lens.unifi.it/ew/dwl.php?...pplication/pdf Source? http://store.raqware.com/product_inf...products_id=63 still says they sell them for ~$100, qty 1. (ouch!). tonyv Last edited by tonyv; 12-10-2007 at 09:01 PM. Reason: found good link |

Great work!
I like that little power supply. A similar part number (Red Rocket Power supply bought out the company) is available from Arrow at www.arrownac.com. The part number is VLT60-3000S55LF and the price is $61.57. That 2 x 4 x 1 inch profile is great. The correct new address for Red Rocket is... http://redrocketp07.s3.nextex-media.de/ I have some similar supplies that are a bit bigger 3 x 5 x 1 inch, that are a fraction of that price here... http://cgi.ebay.com/ws/eBayISAPI.dll...m=200109647904 That's right, for about the same price, you can get 10 (ten) of these little power supplies. I know (from experience) that this fellow will sell you 1, 2, 5, or however many you want, just ask him. He has about 20 available, and even with shipping, you should be able to get one for under $20.00. Great machining. I too, have a little sherline mill and lathe. I'm not sure you'll need the fans much, but they look "cool." I guess I'm the only person who's mounted the switches from the front. Last edited by Grant Stockly; 09-10-2012 at 10:13 PM. |

Here's a picture of the eBay $9 power supply (plus around $7 for shipping) in the approximate place (above the original.)
It's bigger than yours, but smaller than the original version. I think I'll install it when I get a chance. Would need to cut and drill out a couple of 3 inch brackets. So many projects, so little time. Don't be afraid of socketing all the chips and turning it on!!! I know it's a bit scarey to think it may not work. I think I hesitated for a couple days, double checking solder, placement, orientations, etc. Last edited by Grant Stockly; 09-10-2012 at 10:13 PM. |
