HP 200LX with SCSI bus: Adding more SCSI devices to the Palmtop. Part 2 of 2

Описание: Please watch Part 1 first! Link:    • HP 200LX: Connecting SCSI devices to your ...  

The HP 200LX is an MS-DOS Palmtop PC from the early 90's.

This is the second part of two videos, which show how to connect SCSI-2 peripheral devices such as hard drives, an IOMEGA ZIP 100 drive and in this second video we add a CD-ROM drive and Flatbed Scanner to an HP 100LX or 200LX DOS Palmtop, by using the Linksys ParaSCSI Plus Parallel to SCSI adapter, and the Quatech SSP-100 PCMCIA EPP Parallel port interface adapter card.

The video contains adds a CD-ROM drive, a Flatbed Scanner and 2 more Hard Drives to the SCSI bus, and benchmarks the throughput of all the SCSI devices, comparing them against the Palmtop's RAM drive and a CompactFlash/PCMCIA card.
It is recommended you watch the first video before watching this video, as it will explain more about the initial setup of all the hardware featured in this video.

This HP 200LX palmtop is an IBM PC/XT compatible MS-DOS system with a 16-bit 80186 CPU and CGA graphics system-on-a-chip, a serial port and a 16-bit PCMCIA expansion slot containing a 2GB CompactFlash card for main storage. It has been upgraded with a double speed crystal, doubling the CPU's clock frequency from 8MHz to 16MHz, and a 4MB RAM expansion board, raising the total amount of RAM in the palmtop to 5MB.

If you have any technical questions, or are interested in obtaining upgrades such as double-speed crystals and/or memory upgrade headers and boards, please contact me in the comments and I can help you obtain what you need.
