You should check out some of CuriousMarc's videos on youtube, he's been fixing up the clock modules for that HP 9876A computer 😀
Also, that Visionbook traveler - those things are so rare! There's Hitachi, Ricoh and IBM branded versions of that same laptop, the Chandra design/project. Yours has an MMX CPU so I guess it's a Chandra 2 like the IBM Thinkpad 235?
I've got a similar one, the Opti Talisman, which I think is an off-brand version. Nice laptop, though let down a bit by the Crystal audio chip.
Thanks so much for sharing these links. Will check them.
To revive the Visionbook I'll have to find an adapter or battery first. This might be a problem even though a seller promised to find its original battery. But it's a great little notebook, so happy I was able to get it for cca $8.
nice find 😀 no one knows much about these particular laptops, I think information about them fell off of the internet over the years. The PSU is 15v center pin positive. Mine came with the PSU but I ran it off of an old IBM 16v charger and my bench psu at 15 volts. Lately, I've got enough laptops that I prefer using the bench PSU with jack adapters instead of digging out the PSU for each model.
The batteries, well the thinkpads.com Thinkpad 235 page lists these batteries as working with it:
- This model's design is based off the RIOS Clavius, which was also used by the Magio, VisionBook Traveler, FLORA Prius note 210, and the Endeavor TK-300.
- This model uses two camcorder battery packs in place of 18650 cells. Known working camcorder battery packs: Canon BP-911, Sony NP-F520/F530/F550, Hitachi VM-BPL13.
But mine has the VM-BPL13 type battery and I Think those are the correct ones for it. See this for a reference. My batteries are 1200mah and this one's 2000mah, tempting for an upgrade 😀
