BAUD 9600
OPEN #3,ser2hr
LIST #3


With 9600 baud it works!
I tried with this code you wrote me, but I get long waits between one printed line and another.
Rather something like this works:

OPEN #3, ser2i

In this case I immediately obtain the printing and the correct wrapping of the printed ...

Apple. ImageWriters default to 9600 Baud if I remember that correctly. So, you should probably try this.

Fantastic! I thought serial printers didn't reach these speeds. Tonight when I'm in front of my equipment I'll try with that Value.

I'm trying to connect my QL to a serial printer. The printer is an Apple ImageWriter. It is the only serial printer I have and interfacing it with a Macintosh Classic works correctly. I built a serial cable (see photo and pinout), but when I try to print (see program), the printed characters are ...

Hi Robbizz!

I've had success creating a number of QL -> SCART cables over time, based more or less on the really useful site:

I guess you might have used the same site and, like me, you've used that ...

Hi guys, I found some time to spend with my QL and I built a Video Scart cable myself. I followed the diagram below (the sockets are seen from the front, NOT the solder side). It works very well with a couple of TVs at home but on a small TV/Monitor (where among other things I would like to always ...

If your QL has Toolkit 2, you could use the COPY_H extension to force copying of a header. Or COPY_N to force copying without a header, e.g. if copying to a printer where any header bytes might accidentally act as control codes to put printers in random modes and spoil the listings.

This is very ...

Hi everyone,
I recently built a serial cable for Sinclair QL and I'm trying to understand how to juggle the binary files of my QL and how to transfer the latter from the PC to the QL while keeping the header of these files intact.
I know it's a much discussed topic online and there are many ...

It should, however, react to commands.

So is the fact that the LED doesn't turn on when starting MDV2_ also normal?

Hi guys, today I finally had some microdrive cassettes to test on my Sinclair QL. However, I noticed that at start-up, only MDV1_ has the LED light up, while MDV2_ has no LED light and you don't hear the engine running (for testing) during start-up. I did some reading tests with MDV1_ and it works ...

Originals are as rare as hen's teeth & expensive so I wouldn't bother. The main advantage of getting an original PSU is it plugs in without modifying the computer but if you have a QL plug any PSU with suitable voltages is fine.


This is the power supply I have for my QL. Today I drilled a hole ...
