Item specifics

Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully ... Read moreabout the condition


This is a USA model Sinclair ZX80, made by Timex, and was made in 1980. For more information, please see the Wikipedia article. I have owned this ZX80 since 2005, when I bought it on eBay. It appears to have had a modification made: the addition of two LEDs, which are possibly under program control and did not light when I tested the computer.

I am supplying the ZX80 with the 'A Course In BASIC Programming' book and a Timex 16K RAM pack module. The BASIC Programming manual has some marks made by its previous owner (see photos). The RAM pack's cover is a little torn.

Please note that this is a US model and it has a PSU with a 110V AC input, and it will not survive being plugged into 240V AC. In addition, it outputs video on the VHF TV channel 2, and does not produce a UHF signal. To get a proper picture, you will probably need an old NTSC television, and definitely not one with digital tuning. After many attempts, I was able to get a picture showing the 'K' cursor, and I typed a few simple programs. I have that session on video and have uploaded it to YouTube.

This computer would probably suit an American buyer, so I am making it available to the Northern USA, as well as the UK.

My reasons for selling

Well.. I am getting older and I find that I'm not able to concentrate on all of the projects that I would normally have completed quickly. In addition, I have a large amount of computing equipment that I have accumulated over the years. I figure that since I can't 'take it with me', I may as well sell it to someone who can use it! I hope that the buyer does use it, and doesn't just stick it in a box and leave it in the storeroom, as I did! I am also hoping to move house at some point, and so I need to get rid of some of this gear.

Auction length and postage

The auction will run for 5 days. Postage will be tracked International post, or a tracked domestic (UK) service. Should the postage cost be lower than stated, I will refund the difference.

Concerning the photo quality: these are a little dark due to it being night-time, and I don't have adequate lighting.

Looks like I uploaded a few duplicate images, there. Since I am not able to edit the description now, I'll just mention that you can see a corrected gallery of images at www.brooknet.imap.cc/ebay_zx80/.
