I have PC1500 and I have a cassette of macroassembler rosso $ Schlitengroll ??? Does somebody remember, which the correct name. I would need that software, when I cannot read cassette correctly. I have I/O-unit.

The little pens for the printer can be revived with some patience. When dried up, remove carefully the plastic end, humidify (alcohol) and excercise the roller. It will eventually roll again. Then fill the little cartridge with inkjet ink (available cheap in bottles). I revived the 4 colors.

For the lucky ones, that own this marvel, and its tiny printer-plotter, here''s a supply source :$/Shops/63686166/Products/$22US$20017.01$22 Pens really look like original ones. Did anyone test ? Another option is to refill an original pen using a syringe. More later, if someone''s interested.

As opposed to what someone says below (Franck B.), power consumption of the PC1500 is large, even on fresh Batteries. Years of daily use on the same set of AA cells is simply impossible. See the back of the 1500 : 0.13W consumed !

Hello Debby, as far as I know resetting is done by pressing the "All reset" on the bottom with something long and thin like a pen.

I was blown away by the Radio Shack PC-1 and even more so with the PC-2, both of which I bought as soon as they came out. It is still my favorite calculator 31 years later, and I still do small test proggies on it. This little beast is what I learned assembly on, back in the day of fixed memory maps. To this day, no one has made a better pocket keyboard. The keys were placed just right and at the perfect size to work quickly. And this family of QWERTY keyboards on pocket devices made them the easiest to store variables. Simply unbeatable. I bought a spare on eBay in case my original bites the dust. Don''t want to live without it 30 years from now!

oh yeah, the pc-1500 was boss back then with its graphic engine. was used in math classes to draw those nifty saddle functions in 3-d using the printer that goes along. Had the casio fx-702p and it really didn''t hold a candle to the pc-1500 (was not the same price either).

My Sharp PC-1500 with CE-155 8KB RAM module is still in almost daily use as a calculator. I can''t remember when I last replaced the batteries: a couple of years at least. I used to have the fancy docking station with mini 4-colour pen plotter, but the novelty wore off and the extensions were consigned to the loft.

quisiera saber como hacer para utilizar con la pc-1500 un impresor comun en lugar del ce-150 (plotter),ya que mi ce-150 se descompuso y yo utilizo varias pc-1500 para un trabajo que me resuelven perfectamente estas maquinas.

There's a clone of this machine made by Híradástechnika Corp. in Hungary based on the Sharp license. It was dubbed "PTA-4000" and has been relatively common (well, compared to Eastern bloc IT standards, that is) in during the '80s. It was sold in a kit with the KA-160 plotter/docking station and came with a 16kB RAM modul included.

It's a fun machine. ;)
