The Sinclair QL Forum

One of my customers has purchased a load of second hand cartridges from the software preservation project, cleaned them up, re-felted them and is offering them for sale. They have been tested by re-formatting on a Spectrum microdrive unit.

Some of them lack the write protect tab, but that is easily remedied.

Not a bad price (£10 for a set of 4) either considering the fiddly work involved - I have had some sent to me and they look excellent

I can vouch for these, I bought a couple of sets, and they have been by far the most reliable microdrive cartridges I've got, thus far!
