Sinclair ZX80 / ZX81 / Z88 Forums

Looks in very good condition. Worked when I last used it in the early 1980s. I assume it still works. Unfortunately I can't test it now because I loaned my Sinclair ZX-81 and a 16K memory module to a friend who needed an educational tool for a relative. I I never saw it again, but was glad it was put to a good use.
Here's the link: https://www.ebay.com/itm/202313643997?s ... 1558.l2649

The description of the item is faulty. It doesnt provide a centronics printer port.
Also its very pricy. 100 to 200 $ for a untested memory expansion?
A new memory expansion like zxpand+ is tested, adds serial port, midi, AY3 music and last not least SD card interface for a fraction of this untested memory module.
So decide yourself whether it's worth the asked price.
P. S. I payed 5€ last year for an untested 64k memopak. It worked! And that came complete with box, manual etc.
