Then after a week I noticed not all of them were working properly and then some later out right failed. Even a quick clean of the heads did nothing to fix the ailing tapes. Pretty sure the drives work fine, just the cassettes that are old and buggered.
It's decades since microdrive cartridges were last manufactured. The expected lifetime means they should all be dead or dying by now. As Norman mentioned, the biggest single recent cause of failure is the deterioration of the littl sponge which presses the tape against the heads, it tnds to either crumble or unglue itself. One or two guys (names escape me at the moment) have invested time and money in getting suitable quality felt sponging as a DIY replacement thing, there's even an article about it somewhere, though I can't remember where.

There was a lesser element of hit and miss, though they were never as reliable as floppy disks. Another "feature" of these cartridges was that some would work only in one drive, and always worked best on the drive on which they were formatted, so if you knew they were to be used on MDV2_ best to format them on MDV2_. No idea why, maybe some drives could be slightly different speeds to others, maybe?

If the machine is viewed as a collectors item which is to be used in its original format, you're right, it's sad that these drives can't be used. In purely practical terms, floppy disks are more reliable and hold many times the capacity of microdrive cartridges at a fraction of the cost. If you suspect your drives might be dodgy, Ian at Mutant Caterpillar for example can check or repair the QL at a cost. Most people use floppy disks now, or even the SD card interface or the Qubide hard disk interface (is Jose Leandro still doing those, I wonder?)

I've never really been able to break any ground with programming, but Quill has peaked my interest as a useful wordprocessor. Could see myself using that for a distraction free typing environment.
I suspect that using Quill and the other Psion programs is probably still high up there in terms of what the QL is used for. The Psion programs are still surprisingly good as a modest office package, and there's also the Xchange versions for expanded QLs.

Which one? I'm not sure of the answer to this, I;m afraid.
Haemogoblin wrote:And finally, did Psion ever release Chess for download?
No, as far as I know it's still copyighted software, although second hand copies come up for sale on eBay and SellMyRetro.com every now and then. Might be worth asking Rich at RWAP Software if he happens to have a copy he can sell.
