New blog on (some) rare and old computerby cyberfritz Total messages in this thread: 3 Updated: [ Spreadsheet version: yes ] 03/31/2009 Dear all, if you like this blog, you might want to consider also this (I admit it, my) blog: http://randoc.wordpress.com/ A major contribution (at least that's what I hope) of it is my Ebay prices list of some rare computers together. The blog is all about some rare computers, about the rarity of old computers, and mostly theoretical thoughts about collecting rare computers. In contrast to this excellent blog, you won't find technical how-tos or technical tips and tricks. I'm looking forward your visit. Regards, cyberfritz">... [ read more ] |

Epson PX-8 Video on YouTube.comby billdeg Total messages in this thread: 1 For your viewing pleasure, here is a short stock footage movie of Kelcey using an Epson PX-8 laptop computer: http://www....atch?v=A_6Q7PNd1p8 I received this info from Jan who runs a web site dedicated to the Epson PX-8/Geneva http://www....raan/comp/px8/ H101A (CODE AA) Geneva US keyboard H101A (CODE AC) PX-8 US keyboard H101A (CODE UA) PX-8 UK keyboard I can only speculate why my version has no label, but if I were to guess, I believe the LCD is a replacement screen. I am guessing that there was just one pool of replacement screens, and they did not get the "Geneva" or "PX-8" labels because it was not known whether the screen was being shipped to the US, UK, Japan, or elsewhere. Just a hunch. ">... [ read more ] |

Compaq Contura 4/25cby billdeg Total messages in this thread: 1  The Compaq Contura 425c. Note that the pointing device for this laptop was a detachable trackball mouse, which allowed for a larger keyboard. There is a spring that is used to clamp the trackball to the side of the keyboard on the side front.
The Compaq Contura 4/25c is a 486 laptop that I used to support when I worked at Zeneca in the early 1990's. The Contura was a lighter-weight Compaq laptop of the early 1990s. I received this computer with Windows 95 installed, but it would have come with Windows 3.1. I tested the modem and it worked. The battery needs to be replaced, it would not hold a charge.
