The Sinclair QL Forum

The only changes to the US QL from the German QL are: US modulator/filters/xtal and modest component value changes around MC1377. A bodge board glued on the RAM from the clock crystal that passes the clock through two inverting gates to buffer and clean it up a bit. This gets the clock much closer ...

Hi Per, I tried your programme, and it works perfectly on all of the QLWA files I have tried on SD Cards in Q68 Slot 1 and Slot 2. I had to add open#1,con when running from QD and SBASIC, but works well. Could this be added to SBASIC in a compiled procedure? Or maybe a EasyPTR programme to use a GUI...

Hi,

I was updating the QL Service Manual, which details only Issue 5, 6 UK boards.

Is the USA and German QL circuit board require to be detailed.

The problem, I do not have either these QL boards, so it would be guesswork.

Hi Peter,

The addition of Ethernet is not important, I use QLNET to connect to Q68 and other QL computers,with Martyn's QL Network software is a good solution.

I will see what Detlef is doing, he uses Freecad, which is one my interests.

Hi Derek, that seems rather OTT. Use my routine instead of recreating the WIN drive any time you wish to alter the name. As you say, on Q68 you get to specify a sensible name when you format the disk, however, there is no (easy) way to change that name once its set - for now. Just trying to use exi...

I was going to use the Conec 16-001810E, which looks really good, but in low numbers is expensive. Compared to previous converters, it is still very cost effective. Hi Peter, Yes the PicoVGA adapter is the best version, really well designed. I have 20 PCBs, so will get them built. At present I am u...

Hi Peter,

Can Ethernet be added to QLbase, as QLbase, is an excellent addition to the Qzero.

I may try and design a custom enclosure for Qzero and QLbase, rather than use a QL Case.

Hi, I use QLWarz ( nowi who wrote that...) to renamd the QWA volume name. I have to use QPC2 to perform the renaming. But the best way is to use the method that Martyn uses, and put the correct name of QWA when creating it, which can be done in the Q68. I copy files to the Q68 with Martin Head's exc...

Hi,

I have some PCBs to build, just received some RP240-Zero.

I was going to use the Conec 16-001810E, which looks really good, but in low numbers is expensive.

Maybe a 3D printed enclosure would be a possible solution.

Hi,

What flow control settins are you using?
