Printer attached directly to the SER1 port on the back of the machine, and was accessible using the OPEN #, ser command,įollowed by PRINT #, LIST #, etc. Styled to match the QL in appearance, the With a 240V adaptor being required, rather than 120V as mentioned below.Ī 9-pin dot-matrix printer was introduced shortly after the release of the QL. Replacement paper rolls are still offered for sale - try Which is considerably faster than the ZX Printer. Print speed is around 2 lines per second, Uses thermal paper and features 32 column output as standard. Slightly larger than the ZX Printer, the Alphacom 32 The Alphacom 32 was one of the leading alternatives to the ZX Printer. To the stylus, the paper signal will go high even if the printer is between scans, so the stylus must be turned off before attempting The paper detect signal is also used internally by the printer to make sure that the styli stop off the paper. These bits may be in either state on switch on, and aren't affected by the feed button. Make use of the information you've read in, you should output an instruction (with appropriate data) to reset the latches until the next

If you need a copy of the original manual or A voltage is passed through these pins which causes a spark The surface of the paper by two metal pins which travel across the paper. It is an extremely compact 32 column printer which uses aluminium coated paper. The ZX Printer was released in 1981 and is compatible with the ZX80 (with ROM upgrade), Please see the emulators pageįor details of those available on your platform that include printer emulation. The most common printers are listed below, with links to additional information Sinclair had hoped to produce many more titles on cartridge, including several utilities and programming languages, but the lack of popular support for the interface saw it being withdrawn from sale within a year of release.Īdding a printer to a ZX81 or ZX Spectrum is very easy the most popular models simply attached to the edge connector and could beĪccessed immediately using Sinclair BASIC. On the other hand, the ROM cartridge socket was not successful: only 10 titles were released on ROM cartridge, and as many of the most popular games (the Horace series, and several by Ultimate) were already available on cassette at around half the price, no market was ever developed. Technical details on the joystick are available in the Joystick Interfaces section. The joystick interface itself was largely a success, with many games including support for the 'Sinclair' joystick types. It met these goals very well, but was not particularly popular. Intended to be a multi-purpose addition to the ZX Spectrum, the ZX Interface II provided two Joystick ports, and a ROM cartridge socket that allowed games to be loaded instantly. The command CAT #0, 7 will put the value 0 in address 23768, as will some OPEN and MOVE commands. Note: The original user manual differs slightly from this entry, specifying a range of 1-15.

The ZX Interface I allows up to 8 ZX Microdrives to be connected to a single ZX Spectrum, features an RS-232 port, and provides More complex, and is discussed in more detail. The ZX Interface II is the simpler, being essentially a Joystick interface and ROM cartridge slot. Sinclair Research produced 2 official interfaces for use with the ZX Spectrum, both of which are documented below. Brief details of virtually everyĮxpansion developed for the original ZX Spectrum are available from the Listed are supported by several modern emulators. Some of the most popular peripherals produced for the ZX Spectrum are introduced in the sections below.
