The first handheld equipped with OLED display

Sony CLIE PEG-VZ90 is a remarkable Palm OS based device. It’s the first handheld equipped with an OLED screen. It was released 17 years ago. Today OLED displays are commonplace. All the best smartphone displays are made using this technology. But how does the first portable OLED screen look compared to typical LCDs of the same era? Let’s compare the PEG-VZ90 with four other devices of different classes, from low-end to high-end:

• Sharp Zaurus SL-C1000
• Sony CLIE PEG-UX50
• Palm Tungsten E2
• Qtek 9000

There is no doubt that an OLED screen provides the best picture quality. But Sharp’s CG Silicon LCD looks surprisingly good compared to the OLED screen.

Sharp PC-3100 floppy disk drive

Floppy disk drive for Sharp PC-3100 (CE-301F) is a very rare device. It’s quite hard to find even a decent photo of the device. Let me quote

A late Austrian Sharp user Club Magazine lists a "discounted Group order" with a Price of 8000 Austrian Schilling for the PC-3000, 10,000 Schilling for the PC-3100 (Around 20% more) and – interestingly – about 4700 Schilling for the floppy. Yes the Floppy costed more than half of the PC-3000, making it one of the most expensive floppy drives ever sold at that time… And it explains why the floppy is so rare these days. The Floppy disk drive mentioned in the PC-3000 article obviously also fits for the PC-3100.

Therefore I decided to share few high resolution photos of the disk drive.
