However for me a few attempts at resetting with/without holding down a key brought up the European/USA mode. Can''t seem to find a manual in English but I have a 1251 manual so was able to figure out the RSV mode for example. author date text Ken (England) Wednesday 2nd December 2020 I just fired up a PC-1260 and got the Japanese characters.

I tried several things, but to no avail. In the end, I tried this:\ - remove batteries\ - set the on/off switch to Pro (or RSV, I''m not sure)\ - put the opened PC-1262 upside down in it''s plastic hard cover (to avoid to accidentally press a key\ - $ new batteries, but do not slide the battery compartment cover at this moment\ - press and hold the all reset switch, at the same time slide the battery compartment cover over the batteries For me, that worked fine. The PC-1262 came up in European/USA mode again. However, I am not sure about the position of the on/off switch I used. author date text Miguel (US) Friday 10th April 2020 Hi, I recently got a Sharp pc-1261, and everything so far seems to work...although it''s in Japanese. When I use the Help feature, all the basic terms are in english. There must be a way to switch to English, the reset button doesn''t see to do it. Thanks author date text Ra Tuesday 18th July 2017 David, What are the difference between the PC-1260 and 1251 ? Is it hardware or software (instructions) ? Thanks author date text David Thursday 12th March 2015 «downloadable versions of the programming/operations manual that is in English»: on the net you can find Enlish manual in PDF for PC-1251: operation is near identical to PC-1261 with only a few differences (I can tell you some of the differences). Manual for PC-1251: http://pocketcomputerworld.free.fr/Manuals/PC-1251.pdf author date text tonymax2 (Columbus, Ohio area/USA) Friday 28th November 2014 CyberSpider, I have a Sharp PC-1261 with CE-125 Printer and Microcassette Interface and all the manuals (3, English). Neither has had a lot of use. I wanted to use them recently but the PC-1261 no longer works correctly, most likely due to bad connections from the 2 segmented rubber strip LCD connectors used in this device. I''ve tried cleaning/re-seating them with very little success. I don''t hold out much hope of getting the 1261 operating again since those connector strips are not a commmonly available item. I''d be interested in obtaining a working 1261 or 1262 in exchange for good copies of the manuals. Please e-mail if interested to mreilly1@columbus.rr.com. Thanks author date text CyberSpider (USA) Sunday 28th September 2014 I recently was given several PC-1260, PC-1261, and PC-1262''s, a cassette interfaces and a combo cassette/printer interface. There was no documentation with any of the devices. Does anyone have a downloadable versions of the programming/operations manual that is in English or translated from German? Every manual I have found is from bad scans of the German manual which have so far defied any attempt to software convert to searchable pdf and translate. The backgrounds have text imprints from other pages, random dots all over the place, and the images are skewed at various angles. Please respond here because I think a lot of searchers eventually end up here. author date text AkirIkasu (United States) Wednesday 27th August 2014 For those stuck in Japanese, one should theoretically be able to just press the reset button on the back and it will be reset to whatever language your localized machine should be. You can change your system between Latin and Japanese characters easily with this program (provided by Pierre of the pocket computer museum forum at pocket.free.fr): 10 " " POKE 12349,10+NOT PEEK 12349: END The problem is, if you actually have a Japanese one, you will not be able to write it because it types in Japanese. You should be able to shift into Latin characters by pressing Shift than SML, in theory. This program will run whenever you press DEF and the space key. Make sure you are in PROG mode when you write it and in RUN mode when you want to run it. You can also put it on line 65279 so that you can write other more useful programs without erasing this part. author date text M-C Sticker (France) Monday 10th February 2014 Hello, HELP !!!!!

These small pocket computers were derived from the PC-1251. They had same keyboard and size. The main difference was the larger display, which now provided two lines with 24 characters, which was a great advantage, especially for BASIC programming. The built-in BASIC interpreter was also close to the PC-1251 interpreter.

In 1984, the PC-1260 and PC-1261 were released. The only difference between these two was that the former had 4 KB RAM and the latter 10 KB. Internally, they were operated by the SC61860 CPU (8 bits), which was clocked 33% faster than in the PC-1251.

The CPU was mounted on the main PCB, together with the two display driver chips SC43536. Memory was incorporated on a second small PCB. The PC-1260 had the SC613256 ROM plus two HM6116 8K x 8 RAM ICs. The PC-1261 had the same ROM, but five "naked" RAM chips, i.e. chips without DIL case, mounted directly onto the PCB.

Two years later, the PC-1261 was re-released as the PC-1262. It was identical in functional terms, but had a different case color scheme. Internally, it was based on the same main PCB, but the memory PCB was now equipped with a SC623257 ROM, a HM6264 8K x 8 RAM, and a LH5116 2K x 8 RAM.

The picture represents a PC-1261 mounted on a CE-125 micro cassette recorder and thermal printer unit.
