Hi again Martin Not sure how a multimeter would.ipact your readings, but I regularly use my simple/cheapo USB digital analyser with PulseView software to monitor those signals. There's something at the back of my memory about how FET's can be turned on during cold testing with a meter. But I might ...

Thanks for the description. I've got to sit down and do testing on a working unit, to see what I should expect. I've been looking at these COMMS IN/OUT signals, as I found during cold testing with a meter, different readings on these pins on the two microdrive units in the faulty QL. However I also ...

Hi Martin! I've never had a problem with RESET that required that Cap to be replaced - when I have hitn problems with reset, it was either down to the ZX8302 or something more fundamental with the main ZX8301, but replacing the Cap is a simple and cheap enough operation to eliminate it. I've notice...

A couple of months ago. I had to dig out my old QL's, to look at a QL network problem. And of course none of them was working correctly any more. All of them of them having at least one problem, And I have now got around to trying to fix them. I am replacing all the network sockets, as they are all ...

Do you see the same swapped colour effect in other stipple patterns?
Maybe SMSQ/E just uses a different 'chequerboard' stipple pattern, which would not effect the colour seen by the eye.

Here is an update for the IP Network driver, Brings it up to Version 1.16
It fixes a problem on a remote stations. Causing corrupted data when using INPUT in certain circumstances on Nx channels.

Here is an update for Q68 Ethernet driver, It brings it up to Version 0.45
Fixes problems in End Of File handling in IO_FBYTE, and IO_FSTRG on IP channels.

Now going to the point: on the Q68, in the boot, I run a little program that, using tcp, connect the Q68 to the site "time.nist.gov:13" and keep the Q68 system date/time updated, all is fine and everything works , in the program to open a channel I am using the SB line "100 OPEN_IN #...

I received a Quanta magazine as an email attachment yesterday. Not had a chance to read it yet, just a quick scan through.

I would also suggest unplugging the cables from the floppy drives them-self's. In case one of the drives is faulty.
