Cherry Electrical MX SPOS Credit Card Reader KeyboardPrice is link:
$10.00 BIN + 13.75 shippingHISTORYI bought one from the same vendor 23 November 2009 for $9.99 BIN. It's now $10 BIN, with one auction in between for $12 BIN. He probably sold zero at $12. Took exactly 7 days to reach San Francisco (area) California.
KEYSThe keys are all cherry browns (haven't removed spacebar yet). Feels a slight bit more stiff than my 2 year old cherry browns, significantly more noisy than the 2-year olds, lower pitched than the Cherry Blues on my Scorpius M10. Width is 14.25 inches (35.5 cm), almost exactly the width of my scorpius M10 without numberpad.
LAYOUTI'm not a touch typist. The arrow keys are visually hard to find in the compact space, so I put white keycaps on them and now everything is AOK. The [INS-DEL Home-End PGUP-PGDN] grouping is above the numpad, making DEL harder to find by touch, but exposing PGUP-PGDN beautifully to my hand off the right edge.
There is no right ALT key unless you program one. This is inconvenient, but seems to be curable. See next section.
Spoftware required for Magstripe and programmable keysCherry software (free but hard to find) is required to enable the credit card reader (hence the POS in the keyboard model number).
- Magstripe - After default installation, the magstripe reader outputs the text as if it was typed into the keys, (for example into notepad or whatever the foreground application happens to be.) This is quite useful for entering credit cards online, because the card number is the first piece of data on the magstripe, and most web forms ignore extra characters.
- Programmable keys - The software allows reprogramming of the normal FKeys and the blank row above them, all under transparent tops. You can also reprogram the numeric keypad. However there are no transparent covers to simplify relabeling the numeric keypad.
WhateverThere are four green LEDs. Caps, Num, and Scroll toggles as expected, plus a momentary flash on LED 4 when a card stripe is successfully read. Those cylindrical rubber feet are near worthless, They raise the board up, but it's unstable. I plan to open her up tomorrow night.
It was packaged in what appeared to be factory box, but there was no USB-PS/2 adapter. N key rollover web page showed me QWASFD once, so 6 key rollover is tested.
IMPORTANT CORRECTION: 2-key rollover.
EDIT
and the keyboard torques much more than my Scorpius M10. Almost forgot that part, but I have a reputation to uphold.
My Pics - Note that the board came with only black keys. The white ones are mine from another keyboard.

the flaw on the N key is a drop of spit. żI must have been drooling?

Auction Pics - I received the Serial number 000019 shown in the picture. Unless they are all SN 000019.



Not at all bad for $24 USD.
