Re: QL SER-USB from MEMORY LANE

Adrian dropped the project because he never got it working properly with a standard QL. Tobias That's roughly correct. The problem relates to nesting calls from a directory device driver into the QL serial driver, specifically calling the serial driver to read a block from the device. I spent a lot...

Re: Reverse engineering rare hardware

The simplest thing to build on a ROM slot would be an SD card interface. This has of course already been done. The hardware designs, Verilog source for the CPLD and the QL drivers all exist as the QL-SD which I developed in collaboration with Peter Graf. In fact, the working prototypes were demonst...

Re: Faster/wider CPU...

I'm also interested in what Mr Navigator has been saying about using the RaspberryPi for example. I liked the idea of adding the keyboard he saw on Amazon to the QL case, RPi innards running a QL emulator. Gives one possible two-in-one machine solution to all this for those who prefer Linux and giv...

Urs, Your Ser-USB in that video seems to be spending an awful lot of time sitting there not responding to a DIR command (3 minutes or so!). From what I can see on the video, it looks like the watchdog timer abandoned the I/O attempt as non-responsive. I think you forgot to issue a QM_GO command afte...

Re: Possible new stuff for the BBQL

For anybody who may have missed that mailing but are on this forum, here is the change list: * New alternative Ser-USB FAT Driver allows the Ser-USB to be used with FAT12, FAT16 and FAT32 volumes. This driver is now the recommended one to use on low-end configurations and works on an unexpanded QL. ...

Re: usbwiz ser-usb interface

read the manual before buying, as there are differences in floppy-disk and ROM version of the driver, you have to find out, which one is more suitable for your needs Actually, both drivers support the same feature set, but the ROM driver is constrained by being limited to fitting into a 16K EPROM -...
