The complete Sinclair ZX81

Sinclair's tiny, sleek, and very successful 8-bit micro, the lovely 8-bit Sinclair ZX81, is a brilliant machine to collect for, has had some excellent games written for it, still enjoys a vibrant homebrew scene, and -handily- is tiny enough to find its place on any desk. You can grab one complete with everything you might need via this Sinclair ZX81 eBay auction.

The computer is in full working condition, comes with the almost necessary 16k RAM expansion, the ZX Printer, power supply, leads, and even the micro's poly inserts. Add the manuals and some excellent books, all you'll need to add to the setup will be a cassette player.

Seller ships to the Americas, Europe, Asia, Australia, and New Zealand.

ZX80/ZX81 16kb RAM-pack

If you actually are a happy Sinclair ZX80 or ZX81 owner, you do know you definitely need the 16k RAM expansion. So, if you are feeling modestly lucky you could grab this boxed but untested Sinclair ZX 16k RAM. Seller ships worldwide.

Flight Simulation (ZX81)

Flight Simulation by Psion is an aptly named flight-sim for the humble Sinclair ZX81 and probably the only attempt at a realistic simulation using only ASCII characters. You can grab it via this Flight Simulation auction. Seller ships only in the UK.

Forty Niner (ZX81)

Well, Retro Treasures is back to normal (and preparing a few new features for your entertainment) and I thought I'd remind you all of the pretty excellent Sell My Retro auction site, that does seem to have a soft spot for them classic 8-bit micros. This lovely copy of Forty Niner for the Sinclair ZX81 is a prime example of the quality -and even obscure- games you can hope to find there. It comes in its original case, sports some lovely cover art and is one of the most impressive ZX81 games released. Find out more about it here. 

Boxed Sinclair ZX81

The first truly popular, truly affordable and good looking British micro that was also capable of playing some truly classic games was none other than the Sinclair ZX81; the Spectrum's daddy. Oh, and you can grab one (probably) for cheap via this boxed ZX81 eBay auction. Seller ships worldwide.

One Lovely Vintage Computing Bundle

One Sinclair ZX81 and one Commodore VIC 20 in their respective (and respected) boxes can be yours, provided of course you try your luck with this vintage computing eBay auction and are a resident of the UK. Both micros are -according to the seller, that is- in excellent working condition and come with all necessary bits and even a host of extras, such the ZX81 RAM-pack, a Sinclair printer, and the Commodore 1530 datassette.

Sinclair ZX81 16k RAM Pack

You've already got your glorious ZX81 and are all proud and refreshing your BASIC skills. Then again, it would be nice to try some classic and professionally produced games like Mazogs and 3D Monster Maze, wouldn't it? Well, I'm afraid you'll need some extra RAM in the form of a wobbly ram-pack for that. Go get a boxed Sinclair ZX81 16k RAM pack @ eBay and play away. Seller ships only within the UK.

Festive, expensive and impressively mint Sinclair ZX81 in kit form

If you simply want to have a legendary 1k Sinclair ZX81 for your vintage computing and retro gaming needs, better avoid this rather impressive boxed, new, Sinclair ZX81 with the Buy It Now price of £225.00 (seller ships worldwide). The average ZX81, after all, goes for less than a sixth of that price. Then again, what we have here is a truly rare, mint condition, obviously unassembled ZX81 in kit form, that might have sold for a more than reasonable price two decades ago, but is as collectible a Sinclair as they get these days.

Rare boxed Sinclair ZX-81 sighted

The Sinclair ZX-81, the ZX Spectrum's daddy, was released back in 1981 and was probably the first home computer capable of playing some decent games. It was after all the home of classic maze game 3D Monster Maze (read an excellent making of... article over @ EDGE) and brilliant Sabotage. The machine featured some lovely black and white ASCII graphics, 1 whole Kilobyte of memory and one of those dreaded membrane keyboards.

The ZX-81, despite its now laughable capabilities, is quite a rarity and usually sells for over 60£, 120$ or 85€, which means that this boxed Sinclair ZX-81 auction @ ebay is a definite bargain. Happily, seller ships worldwide.
