The HP-110 was the first laptop computer to offer the power and the possibilities of a desktop. 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.

I bought the 110+ in 1985 with the disk drive and printer and the screen upgrade to 26 lines and one megabyte of RAM. 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.
