 the sharp pc-1500 was a pocket computer produced by sharp during 1981-1985. a clone was sold as the trs-80 pc-2. the whole computer was designed around the lh5801, an 8-bit cpu similar to the zilog z80, but all laid-out in power-saving cmos circuits. equipped with 2kb of on-board ram, the programming language is basic. later german engineers  provided an assembler for the machine. later even a c compiler followed. an external slot is available and accept memory (from 4kb to 32kb) and rom modules. we know 7 version of this pocket computer with 2kb memory : *sharp pc-1500 japanese version (1981) *sharp pc-1500 japanese version with blue paint around lcd. known as pc-1500d (1984) *sharp pc-1500 european version (1982) *sharp pc-1500 rp2 brazilian version (1982) *hiradastechnika pta-4000 hungarian licence. *hiradastechnika pta-4000+16 hungarian licence (with internal 16kb memory extension) *tandy trs-80 pc2. and 2 versions wit 8kb memory : *sharp pc-1501 japanse rework with 8kb memory (1984) *sharp pc-1500a european rework with 8kb memory (1984) ==technical specifications== *156Ã7 pixel lcd *integrated speaker *integrated rtc *memory/cartridge slot *expansion port for printer and tape drives *battery slot (4Ãaa) *connector for external power supply (official adaptor is sharp ea-150, rated at 500ma @ 9v, comes with the ce-150 printer interface.) === accessories === *ce-150 4-colour printer/plotter and cassette interface in travel case. known as ka-160 with pta-4000. *ce-151 4 kb memory module *ce-152 cassette recorder (as external storage) *ce-153 software board *ce-154 wallet dedicated to pc-1500+ce-150+ce-152+ce-153 *ce-155 8 kb memory module *ce-156 tape with katakana software *ce-157 4 kb memory module with cr2032 battery data backup and katakana chars rom *ce-158 communication dock with rs-232c and parallel interface with (4 rechargeable, shrink-wrapped, permanently built-in) nicd battery (aa) as additional power supply for the computer. *ce-159 8 kb memory module with cr2032 battery data backup *ce-160 7,6 kb read only memory module with cr2032 battery data backup *ce-161 16 kb memory module with cr2032 battery data backup *ce-162e tape and parallel port interface *ce-163 32 kb 2x 16 kb dual-page memory module with cr2032 battery data backup note: only one page (16 kb) can be accessed at a time, switchable via the following command in prog mode: page 0 [enter] poke&5804,0 [enter] page 1 [enter] poke&5804,1 [enter] ==related sharp pocket computers== * sharp pc-1210 * sharp pc-1211 * sharp pc-1251 * sharp pc-1500 * sharp pc-1500a upgrade version with
