|Robot Series PL-6150 with original packaging.|
Odds are you're not going to find a PL-6150 for sale anywhere. It's primarily used for promotions, so any company's logo can be printed on it. These companies can buy them for $2-$3 each and will probably just give them away. And honestly, that's the only acceptable way to distribute these. The PL-6150 is a garbage calculator.

What's also slow is calculator part. After pressing a spongy button, it takes roughly a third of a second for a digit to appear on the screen. These fractions of a second add up quickly if you're performing operations on numbers larger than 99. To make it worse, the screen doesn't provide much contrast, so I had to hold this calculator at an odd angle to see what was going on.

Also strange is the choice to use two micro screws to hold in the battery cover. These are completely unnecessary as the cover remains in place just fine without them. All they manage to do is increase the cost of the device and make replacing the battery more inconvenient for the end user.
This is another example of what I really hate calling a "disposable calculator." As a collector, I find these to keep in a working state for as long as I can. As someone who cares about the environment, it disgusts me that plastic and electronic components would be used in such a wasteful manner. I can tell that some care went into the design of the PL-6150 because it has some really nice qualities, but because it's meant to be cheap and replaceable, functionality was severely sacrificed.
I found this calculator at a thrift store (not Goodwill) for $1.99. I have no idea what year these came out, but they are manufactured in China.

Thanks for the information, and for your site. I found a 6150 Robot while cleaning out some old toolkits I hadn't looked at for years. I found it (marked GM) and it looked so well made and groovy I thought it was worth replacing the battery. Had to look all over to find a small enough phillips head to remove panel; had to work to pry out battery. Then I thought I should google the thing, found your review and pitched it. I have a TAX HotLine by Hanig I've been punching so long I've had to re-mark the keypad half a dozen times. Also have a Canon Palmtronic from about 30 years back- weighs over half a pound. made in JapanReplyDelete
Wow, I'm so glad to hear that this helped someone! It's a shame when calculators with neat features end up being terrible though.Delete
Had to look up the TAX HotLine, and wow, that thing looks nice. It's got a very clean design. I can definitely understand why you'd keep it around.
