2015-02-25 - Sinclair QL testing - some non-working keys and Microdrive read problems

Tested this Sinclair QL which I obtained with a batch some months ago.

A customer is interested, so let's get it checked out and repaired where needed.

Testing
Machine booted up correcly, connected with RF output to LCD TV.

Problems
Non working keys: column '0', 'P', etc. Will need a new membrane.

The first Microdrive cartridge I tried did not load completely: the load screen is shown, but after that it endlessly searches for more data.

Solutions
I will install a new membrane (will get them from RWAP at SellMyRetro.com) and some new Microdrive rollers (same source).

More info will follow.

Update:

Replaced rubber rollers: Microdrive 1 still doesn't read well, also doesn't make a smooth sound.

Swapped Microdrive 2 with 1: software still doesn't load well.

Grabbed a working QL: the cartridges I was using are not ok.

Picked another Microdrive cartridge with working software: now it loads allright.

Still need to replace keyboard membrane.
