Re: Unused ED Disks

You can rip ED drives from used IBM PS/2 models that had them pretty much to the end of their lifetime.

Such computers can be found on eBay or, if you're lucky, the dumpster (where I have my drives from)

Re: Enable Caps Lock from SuperBASIC

r all, why should I want/need the same CAPS state in, say, QTPI and Text87? That's not what I said. I want the CAPS lock state that I know I have set . And don't want it modified by an application. Apparently, there's a little LED set in my head that's getting out of sync when applications change C...

Re: Enable Caps Lock from SuperBASIC

Well, the simplest case of workaround is simply uppercasing the input string and re-printing it. I think that is what you should do if you want upper-case input only. On a multi-tasking machine that only has one caps lock state, I would actually consider it bad behavior of an application to hog the ...

Re: Drivers and linking...

suffice it to say that during development of a new driver, using LRESPR to load it into the system would be the ideal way to get a new driver in and replace the old driver. That should hopefully simplify things... Yes. The old driver is not actually replaced. The new driver is placed at the end of ...

Re: Drivers and linking...

Well, to be even more precise, the Trump Card ROM actually lives in more than one place during the boot process. Initially, it lives at $C0000 (otherwise the ROM wouldn't be recognized by any Sinclair ROM), and once it's initialization code is running, relocates itself to the "internal I/O&quo...

Re: Behaviour of SER_BUFF in QPC & SMSQ/E

For the QLUB project, I appear to need to extend the SERial buffer beyond the (old) default of 81 bytes to ensure messages are not split when transmitted via the virtual COM/USB port to the microcontroller and the SER_BUFF procedure seems to achieve this nicely when running my SBASIC test 'wrapper....

Re: Behaviour of SER_BUFF in QPC & SMSQ/E

Does the USB to Serial microcontroller device/software handle RS232 handshaking, hardware Ready/Busy, or XON/XOFF? Can it buffer data if QPC2 is says it's busy, or does it just pass the data through regardless? If it does not halt the data, then you would loose data. Which increasing the serial buf...

Re: Drivers and linking...

That is, unfortunately true only for the last QL ROMs (JS, MGx, and Minerva, to my knowledge) and SMSQ/E. There were a number of bugs in the earlier ROMs that lead to the fact that some (OS) ROMs could not simply overwrite existing drivers, some (OS) ROM versions also wouldn't find an initialize mo...

Re: TF Services I2C drivers

Dave, they're part of Minerva MKII which supplied the I²C hardware. You should be able to find software support here: http://www.dilwyn.me.uk/qlrom/index.html (See "Minerva Utilities") Note these drivers and tools would talk to the keyboard co-pro, thus maybe not so useful for stand-alone ...
