That's the old prototype board. The series board is documented here:

Re: Microdrive

Nevermind. It wasn't too hard to guess. Attached is a quick hack for a qemu2qlay converter that runs on a Linux PC.

Re: Microdrive

2. The Qemulator .mdv image files (size varies). This comprises of a special header, followed by Sector zero, then the highest good sector, followed by sectors counting down to sector 1. There are no preambles or checksums for the blocks. Please tell me the details of this format. I'd like to conve...

QIMI version of ICE?

I am considering to add mouse support to my FPGA QL. There's the MICE ROM which would be nice for a quick test. But that seems to support a slightly different interface which isn't supported by any other software. It seems futile to implement that. QIMI on the other hand seem to rely on stuff loaded...

Re: QL on MIST FPGA board

BTW: Joystick and the usualy PC key bindings (Backspace to ctrl-left etc) now also work. So i'd say i am 99% done with what i wanted to achieve. I will release the binary and the latest source code this evening. Resource usage on the FPGA is 26% for logic and 6% for FPGA internal memory (the 8049 ha...

Re: QL on MIST FPGA board

Yes, you need to get used to this kind if thinking. E.g. this code: a <= 0; if ( a != 0) begin .... do something end makes absolutely no sense to a normal programmer. In HDL this is a very common thing since the assignment (a <= 0) and the comparison (a != 0) happen at the same time. So if a at a gi...

Re: QL on MIST FPGA board

I just released a new core incl. a "real" IPC based on the t48 core and the original firmware. This allows to run games as keyrow scanning now works. And there's also audio. I'll upload another video once i find something interesting to show. Quill and the PD games i found aren't that ente...

Re: Microdrive

The arm is doing all the usb stuff and controls the on screen display. If you use ps2 keyboards and mice and map the menu options to physical buttons and switches and load the rom and a mdv image into flash then you don't need the arm anymore.

Re: QL on MIST FPGA board

I am using that concept everywhere. E.g. the Atari ST core can use USB-Ethernet dongles to go online. To the Atari ST this looks like an old ne2000 based ethernat so the original network drivers from 20 years ago can be used. And yes, adding sd-ql support should actually be quite simple. So should b...
