Repairs to a Heath WH19 Terminal
by Jason Perkins 27 Mar '17

27 Mar '17

Looking for some advice on getting a Heath WH19 terminal going again. First, some schematics: http://www.rsp-italy.it/Electronics/Kits/_contents/Heathkit/Kits/Heathkit%2… My annotations on the x-ray view: https://goo.gl/photos/PF8N7wRDPLc1czUU7 What I observed: When first powering the terminal it did nothing. The fast blow 1A fuse was open, the wire was broken. As it was handled it broke more, suggesting it could have simply failed from vibration? The manual said that a 2A slow blow fuse is appropriate for 120v operation. I replaced the fuse with the smallest one I had on hand, a 4A slow blow, connected the terminal to a current meter, and powered it up. It beeped :) But was drawing 5A :( and then there was a little smoke :( :( I quickly powered it off. R263, a 1.2 ohm 2W resistor had cracked. R263 supplies the +53v rail to the horizontal section. C228 seems to be good (open resistance, correct mfd), D208 and D211 seem to be good (.5v one way, open the other), C229 isn't shorted but my meter can't measure its capacitance. I replaced R263 with a 4w 1.2 ohm resistor I had on hand, and powered up again. Still too much current draw, and more smoke in the area of Q217. Does this suggest Q217, the HOT, is bad? I pulled it out and did the diode test on it, it seemed to test OK? It's a BU500, and I see some NOS ones on ebay. I'm unsure what my next step should be. Thanks for your input! -- Jason Perkins 313 355 0085

All, I've got a Libretto 110CT that needs a power adapter, thought I'd check here before hitting eBay. I believe they're all compatible. Thanks, Jonathan

one computer too many (how can that be?)
by Steven Michelsen 27 Mar '17

27 Mar '17

Last year at VCF-East, among other things, I bought a circa 2003, Mac G5 Tower. I have never gotten to test / use / play with this machine in the last 11.9 months, and at this point I may never get to it. So then, it's free to anyone that wants to pick it up here in Succasunna, NJ. For myself, I am in the process of packing up my toys and moving to southern Delaware. I had grand plans to attend more of the monthly workshops to learn from the "gurus" that frequent them, but this is less likely now that I will be 3 hours away. Darn. So contact me here or off-list at stevenm(a)optonline.net <mailto:stevenm@optonline.net> and arrange to cart off my Mac Tower. BTW It comes with no accessories (except a power cord if you need one, which I doubt (g)) Best, Steve Hitting the road with a bunch of '80s hardware https://dl.dropboxusercontent.com/u/65762317/forums/on_the_road.jpg

Museum update
by Evan Koblentz 26 Mar '17

26 Mar '17

Midnight -- leaving the museum now. It's a mess, and there is still a lot of work to do before the show. I was going to come back Wednesday morning. Now I think I'll come back sometime Tuesday afternoon. The good news is Adam and I (and also Jeff B. and Chris F.) got a ton of stuff done this week. Way too much to itemize. Adam and I determined some wrinkles in the weekend's plan, but we put our brains together and worked through all of it.

Can set-up take place on Friday during the day? I know a lot is done in the evening but are the display halls open during the day? Bob

Hotel Suggestion for VCF
by Chris Fala 26 Mar '17

26 Mar '17

I have stayed at the Residence Inn Marriott in Neptune on Jumping Brooke Rd. It has a pool, free hot breakfast, etc. For those looking for a nice hotel who also want to split the cost with a friend or two, I discovered that they have a two bedroom, two bathroom suite with one king and one queen bed and a fold-out sofa bed. Nice option for multiple people to also have some privacy. The rate for three nights (Thursday through Sunday) is $657, which split three ways is a pretty good deal. Hope this helps.

FS: iMacs
by Systems Glitch 26 Mar '17

26 Mar '17

All, I've got a few iMacs I'd like to part with at VCF East: 1x indigo G3 slotloader -- with keyboard and mouse 1x lime G3 tray loader -- with mouse, OS X 10.3 installed, works 1x Intel Core 2 Duo white, OS X 10.4 installed, has typical colored vertical lines issue $20 each. I won't bring them if no one claims them. I believe the indigo G3 also works, but I haven't powered it up in a while. The Intel iMac does have vertical lines issues, but it's not so bad as to be unusable. I can pull up system specs if anyone is interested enough to request them. Thanks, Jonathan

Free empty boxes for IBM 5150 PC + monitor
by matt＠mattmik.com 26 Mar '17

26 Mar '17

I know empty boxes aren't really worth anything, but if anyone's interested...I have the original boxes for both the IBM 5150 PC and 5151 monitor. They're free to a good home. They look like this: https://www.classiccomputershop.eu/Files/5/17000/17331/ProductPhotos/MaxCon… http://www.computercloset.org/IBM_PC_System_Boxed.jpg I believe the foam inserts are still inside. Let me know. I'll be at VCF East on Saturday.
