My friends, a thread! I managed to bag a #casio #fa10 with case, a #pb700 and 2 RAM modules from a friendly chap in Switzerland. The unit was not in the best condition when it arrived. 1/8 #ポケコン
I did the case cleanup first, because easiest. It was mostly dirty & the metal parts very rusty with quite a bit of pitting. I used car cockpit cleaner to scrub the case & removed the rust with a wire brush. 2/8 #ポケコン
After polishing it doesn't look half bad. The metal parts are still pitted, but other than grinding off a lot of material, I don't see how to get rid of that. Next on the list, the #fa10 itself. Amazingly, there was no corrosion and the NiCd is ok! 3/8 #ポケコン
And last, the #PB700. The battery compartment and RAM slots showed no corrosion, but someone had managed to get something behind the LCD window. This sadly meant I had to open the unit. I normally love opening Pocket Computers, but not the PB-700 / 770. 4/8 #ポケコン
Opening the case of the unit is easy. Remove 1 screw in the RAM compartment & pry the case apart with a spudger. Now it gets fun. There are 3 PCBs, the mainboard on the bottom. LCD daughter board(in blue) & keyboard pcb in the top half. That's what I had to remove. 5/8 #ポケコン
To do that, remove 3 screws on the LCD pcb, & another 13 on the keyboard pcb, carefully! pull the PCB/ribbon cable assembly from beneath two plastic guides. This step can go horribly wrong, you're juggling with 4 ribbon connectors at the same time... 6/8 #ポケコン
...as well as trying not to screw up the multipart keyboard assembly or rip off the speaker. If you manage to get everything out, pop out the aluminium screen mask & display window, clean everything and put it all back together. Easy. 😑
Well, it seems to work. 😊
7/8 #ポケコン
Taking the PB-700 apart isn't an easy task, and I certainly wouldn't recommend doing it unless you absolutely have to. That said, I'm extremely happy that I got a working FA-10 relatively cheap. The case, PB-700 and the rest was icing on the cake. 8/8 #ポケコン

Thread time once again! A Package from a fine fellow in Valencia! The contents are something I've been trying to find for quite a bit now. A bit more expensive than what I'm usually willing to spend, but this is special. #ポケコン The address sticker on a package from Valencia, as yet unope
Random side note: It would seem that Lidl Spain had a sale on Milbona products back in March. I hope the Spanish among you had a chance to grab some cheap dairy goodness. Also, nachos.
Well, there you are, my little lovely! I hope you had a nice & gentle journey.
Apparently, you did indeed! Mates, I present the #Casio fx-5400p, the scientific calculator brother to the PB-80!

1/8 Hello my friends, it's been a while, but today I bring a new thread! It stars the handsome bugger pictured below. "But Rick," I hear your imaginary voices protest, "that's not a Pocket Computer!". Well right you are, sort of. #ポケコン Image
2/8 This beautiful #Sharp #IQ8200 comes courtesy of a nice chap in France. Although a great piece of kit, the real magic happens when you add this little IC-Card (#IQ871). A 128 KB #BASIC card which goes into the expansion slot on the Organizer. #ポケコン ImageImageImage
3/8 Well, would you look at that! BASIC! Although the card only has A-T descriptors marking the sensor keys, the functions are identical to the ones on the IQ-707 pictured. Except the 2ndF key which is NCR / NPR on this card. #ポケコン ImageImage

Hello fine folks! I bring you a thread! A long one! Pictured here is a new addition to my collection; the #Sharp #PC1100 aka #EL6300. It's a combination Pocket Computer/calculator/database. 1/12 #ポケコン ImageImageImage
2/12 Sporting a clamshell case, the top half hosts the two line LCD display, the mode selector, power button, the numerical keypad and the keys for database functionality. It takes a lot of its design from the run-time Pocket Computers like the PC-1270. ImageImage
3/12 The bottom half is where your membrane keyboard sits. Typing on that keyboard is better than I expected, or at least better than the PC-1246S or 1248. It features an extremely reduced BASIC command set. Image
