Not only a replacement but also the first computer addition to the collection for a couple of years. Was a sad day June 2019 when I discovered the battery damage to my HX-20, and trust me I have been looking for a replacement from that day. The computer does attract silly prices. Also the condition was important as I only in truth needed the case. I was so pleased to find a good machine at a reasonable price. And here she is. I just now have to remove the battery. The HX-20 is an amazing bit of kit for 1982. It is credited as being the first notebook computer. It not only has its own display but a tape backup and printer. CPU is Hitachi 6301 x 2 CPU's at 614 kHz Memory is 16KB RAM and is expandable up to 32KB 32KB ROM and expandable to 64KB Display is just 4 lines x 20 characters and is LCD Graphics gives 120 × 32-pixels Input is via full-transit keyboard Power provided by rechargeable nickel-cadmium batteries Dimensions generally A4 Size Weight is 1.6KG. When you collect computers you can be forgiven for losing a machine to fair wear and tear but to have one be destroyed by your very own stupidity is something very difficult to reconcile. I should have known there was a battery and I just failed to act. Thankfully I have a second chance at saving one of these little beauties , let's hope I can be more successful this time.
