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.

Santo Nucifora @vintagecomputer.ca · 4d

It was my pleasure. Always glad to help where I can.

As a rare Sphere owner, I just backed Go Computer Now! – The Story of Sphere Computers on @kickstarter.com www.kickstarter.com/projects/bzo... Good luck @bzotto.bsky.social !

Go Computer Now! – The Story of Sphere Computers

A book telling the extraordinary story of Sphere, a 1970s Utah personal computer maker far ahead of its time—until its sudden collapse.

It's the Super PET SP9000.

Santo Nucifora @vintagecomputer.ca · 7d

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.

Santo Nucifora @vintagecomputer.ca · 8d

That is sad. That said, the packing job looks better than some of the stuff I've seen.

Yes.

This is a picture of three #Commodore MOS Kim-1s revision G with two having black sockets and one having white sockets. #vintagecomputer #retrocomputing

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

This is a picture of a Tecmar 10 MB Mac Drive that works on a Mac 128K computer. It boots from floppy but spits out the floppy as it's booting and continues to boot from the hard drive. It has an early Syquest drive that takes a 5MB cartridge. I don't have one of those, unfortunately.

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

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

This is an image of an after-market Memotech Plug-in Keyboard for the ZX81 computer.

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.

Santo Nucifora @vintagecomputer.ca · Sep 1

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.

Santo Nucifora @vintagecomputer.ca · Sep 1

How can I help?
