I used it almost everyday for ten years to run my business on the road and it was a fantastic computer. A battery charge was good for 20 hours of work, much longer to just store data. It had MS Word 1A on a ROM chip and Lotus 1-2-3 and they both ran quickly with no problems at all. As I recall the retail price for everything was somewhere around Seven thousand dollars and it was worth it. I still have it but haven''t turned in on since 1994. - author: Lohi Karhu (Germany) date: Thursday 20th May 2021 text: Rich WIlson (HP3478A Guru) mentioned the PPU in the 11ü, and couldn''t see the part number, but I''ll bet it was a Motorola 146805G2, or similar$ Myself and a friend built the very first evaluation system for this processor, in 1982/83, even beating Motorola to the market... it was one of the first generation of ultra-low power MCUs, ideal for that application, at that time. - author: Denis Wicking (United Kingdom) date: Tuesday 23rd May 2017 text: Just found the complete collection - laptop, printer, disk base, manuals, bag when clearing out my dad''s gear.

As it was possible to connect a printer and a disk-drive to it, it was a very serious machine in its category, with Lotus 1-2-3 integrated. This was the good occasion for Hewlet-Packard to introduce a laptop computer when IBM and Apple were not yet on this part of the market. The HP-110 is somehow compatible with its big brother, the HP-150, and can communicate with HP "calculators" like the HP-41c. Its design looks like the Dulmont Magnum or the Gavilan produced at the same time. The screen can be tilted to accomodate the right angle of vision for the user. The HP-110 is equiped with a 8086 16-bit CPU which is much more powerful than the 8088 for example used in the HP-150. One year later, HP presented the **Portable Plus** with bigger screen, more memory upgrade and the possibility to change the internal ROM software. --- **Rich Wilson** comments:\ The HP-110 and Portable Plus were actually multi-processor computers! I see something on the schematic called a PPU, and its part number seems to be 146?0562. But it's blurry; the ? might be 3 or 8, and the 0 might be an 8. In sleep mode, the 8086 is powered off, and the PPU is given the job of keeping the time, controlling the power supply and charger, monitoring the power button, etc.
