The Sinclair ZX81 was the first popular home computer - it followed on the heels of the white Sinclair ZX80 home computer (which was supplied as a kit) and came either as a kit or ready-assembled. It came complete with built in BASIC interpreter, Z80 processor and a massive 1K RAM (random access memory). The Sinclair ZX81 was the first computer to adopt the Sinclair black colour and originally came with a 700mA PSU, which had the plug incorporated into the power supply unit (akin to the earlier ZX80 PSU). However, when Sinclair released its own add-on thermal ZX printer for the Sinclair ZX80, ZX81 and Spectrum computers, it was found that this power supply was insufficient and the larger 1.2A PSU was released for use with the ZX81 (this power supply unit appears half-way along the cable). A host of add-ons were produced both by Sinclair and other manufacturers, including a 16K RAM pack (notorious for crashing due to wobble). Later add-ons allowed the use of high resolution graphics, and games in high resolution were produced, using a software only solution! If you are looking for information on the ZX81, including emulators and downloads, a good place to start would be the ZX81 webring, although you may also want to leave a message on our Wanted Page. Following a recent acquisition, we are able to offer probably the largest range of second hand items for the ZX81 available anywhere. Sinclair ZX81 Keyboard MembranesWe are now selling brand new replacement Sinclair ZX81 Keyboard Membranes, with the integrated touch key keyboard.
New Sinclair ZX80 / ZX81 Dedicated ForumAs well as our own RWAP Software Forum, which is for discussion of our projects and what people would like to see; we have now created a forum dedicated to the Sinclair ZX80 and ZX81 computers, including emulators and Timex-Sinclair Clones. This has already proved very popular with plenty of discussion and hardware project details. There are even new games being produced, to continue the support and interest in the ZX81. New Sinclair ZX81 / Timex-Sinclair 1000 / Timex-Sinclair 1500 Magazine - "MonoChrome"We are pleased to be able to host this free magazine for ZX81 enthusiasts.
New Sinclair ZX81 / Timex-Sinclair 1000 / Timex-Sinclair 1500 ProjectsWe are currently investigating a range of new
projects for
the Sinclair ZX81 and compatibles. We welcome people to indicate
which projects they would most like to see put into production.
Please refer to our Sinclair ZX81
Project Page. New Sinclair ZX81 / Timex-Sinclair 1000 / Timex-Sinclair 1500 SoftwareDue in part to the inertia behind discussions
on the Sinclair
ZX80
and ZX81 discussion forums, various items
of software have been released for the Sinclair ZX81 over the past few
years, utilising the best tools on PCs in order to create imaginative
software, which is up to (or exceeeds) the standard of previous
commercial releases. More details, together with screen shots and
downloads appear on our Sinclair
ZX81
Software Page. If you are interested in previous commercial
releases for the Sinclair ZX81, then try the Sinclair ZX81 Museum. Second Hand Items - Testing and Shipping We now list all of our second hand Sinclair ZX81 items on our new SellmyRetro site - SellmyRetro.com is a site dedicated to vintage / retro electronics and computers. Our second hand items are in good condition (unless stated) and are all fully tested before shipping. We ensure that they are well protected against the rigours of parcel delivery and send them by Royal Mail First Class post, Parcelforce 48 hour delivery (in the UK) or Parcel2Go (whichever is the cheaper option - Parcel2Go tends to be a lot cheaper for larger items). Although we attempt to keep this list as current as possible, please check on availability of any item prior to ordering. We also offer a 14 day money back warranty on all goods (excluding shipping charges), provided that they are returned in the same condition and packaging. If you are looking for information on the ZX81, including emulators and downloads, a good place to start would be the ZX81 webring. You may also want to leave a note on our Wanted section if you are looking for something in particular.
