The Sphere does still run but I have issues with the CRT that I need to get repaired. I took a shot at it but it's beyond repair skills.
One of my favorites is the Osborne Vixen. Took me a while to find mine. Very compact for a luggable. Very cool computer for the time.
It was my pleasure. Always glad to help where I can.
It's the Super PET SP9000.
Ah. Makes sense. Movement within the shipping box is a killer.
Nice computer. If you lost vacuum on that CRT, I am surprised you don't see any phosphor loss on the front.
That is sad. That said, the packing job looks better than some of the stuff I've seen.
Got my Tecmar Mac Drive working after recapping and repairing the power supply and replacing a shorted cap on the main PCB board. Very cool serial based drive that was available BEFORE Apple's HD20 hard drive solution. #Macintosh #vintagecomputer #retrocomputing
All this Husky Hunter talk is going to make me break out my Husky Hunter that has bad battery damage. Maybe it's time to give it another shot.
I haven't posted a decent computer pic in a while. How about this one?

This is the Comterm Max PC clone in a wedge case. First available in 1984, these were used in schools in Quebec, Canada. From the makers of the Dynalogic (Bytec-Comterm) Hyperion. #vintagecomputing #retrocomputing
You got ThinkerDifferent post.
Playing the "Trivia Talker II" game by #Votrax on the #Commodore 64 with the "Votalker C-64" cartridge installed. I love the classic sound of the speech synthesis from the SC-01 chip within. #vintagecomputer #retrocomputer

Volume UP when watching!
Working on a Tandon computer with an MFM hard drive. I didn't realize you could terminate the drive chain by plugging in a resistor pack terminator this way. I've never seen this before. Very cool. #vintagecomputer #retrocomputer
Found a Memotech keyboard for the ZX81 that doesn't appear to be used. I'm not usually a "box" person but this is a nice one. Will have to try it out the next time Sinclair is in the "review and see if everything still works" rotation. #vintagecomputer #retrcomputer
Happy 50th anniversary to the MOS 6502! Could Microchess for the KIM-1 be the first commercially available game for the 6502? The yellow booklet of the left is version 1.0. You typed it in yourself but there was an optional cassette. Let me know your thoughts. #vintagecomputer #retrocomputer
Awesome. My first Displayphone didn't have a power supply so I used a Meanwell RT-65B and a project box from Amazon to fit the power supply and a switch in it. Worked out well. Glad you got it going. Does the serial port work?
If you've ever dealt with a swollen laptop battery, you'll love these throw pillows on Aliexpress. When I saw these, I thought they were hilarious :)
Here are the voltages. I only saw a flash in the CRT neck when turning on. No glow while it operated. I did start with nothing on screen until I adjusted the brightness but still no glow. I have to fix a cold solder joint while I'm at it :) Good luck!
I need to make little room to dig it out and check. Can these readings be done with just the monitor cover off? Can you send a pic of which connector and where the connector connects? Its been a while since I've opened one and I have three now. One has a bad keyboard.
That sucks. Sorry, I was out. You have bigger issues to deal with at the moment but just for you to confirm later on, here is my EPROM placement.
