Hi, I can't help it, I made a new version of the card.

This is the QLion Silver card where I replaced the cpu with a 68000 cpu core but still kept the accesses mostly 8-bit but with a more efficient way than a 68008 and increased clock frequency. So the result:

It's much much faster done with simpler hardware, I kept the same relatively cheap fpga, the only downside is that it supports 45 sprites instead of 90 because the cpu core took enough space.
Luckily 45 sprites are enough to play the galaxians clone demo game, but it was so fast that I had to insert delays to make it playable, or use the fslow command but this made the game as slow as if it run in a standard QL. So I made a mechanism to slow down the speed in various speeds in 64 steps so one can adjust the speed of QL where he likes and this is also useful for microdrive-NET compatibility. It can be made even slower than the standard QL but who wants that.

Every other QLion feature is supported as by the first QLion card.

This is the QLion Silver card, it has less components than the QLion, I think I can fit one more ram chip in there ;) .

I think with the increased speed and the sprites one may write simple playable games even using just the super basic.

This card is not yet as widely tested as the QLion I only tested it with my 2 QLs, issue5 and issue6 and it works perfectly, using the fslow command it reads and writes to microdrives but more testing has to be done.

Hi Leon,

congratulations! And to be honest, I expected it. ;) Since FPGA CPU cores are faster than a real 68000, it is just too tempting.
On the other hand, using a Motorola CPU gave your previous design a nice vintage flavour.
Personally I'd find something like a SuperGoldCard successor with a real 68030 beautiful.
I wouldn't design it myself, but buy one if available.
(Just saying because your design focus is currently closer to a classic CPU than my own.)

Hi,

I have been using the original QLion board on my issue 5 QL, for a few weeks. The board plugs into the QL expansion, no need to remove 68008 CPU. The operating system is Minerva with Toolkit 2 v2.36 installed.

The I/O connections are VGA, Stereo audio out, PS/2 Mouse, SERial port, Micro SD Card reader. As detailed in the photograph on the first page if this thread.

There is a Real Time Clock, which needs a command to update the QL clock. This keeps the file date stamps in order.

I was supplied with 2 QXL.WIN files with the QXL.WIN files and the other was Marcel's QL-SD demo files.

I copied the 2 QXL.WIN files to a FAT32 formatted 8Gb MicroSDHC card and inserted the SD card into the SD Reader and powered the QL up, gave very nice VGA picture on 19" VGA TV Monitor, displaying the Minerva startup screen detecting the SD Card and the was able to boot off the QXL.WIN file installing devices:WIN1, WIN2

I was able to play Leon's Galaxians game in 256 mode and 8 mode. The 256 colour pictures were displayed verybnicely and a Mandlebrot programme.

I used a Perixx Perimouse as used on the Q68, worked perfectly.

I played the demo sound files through the Stereo audio out to stanard amplified Stereo Speakers, sounding great.

There are some programs Leon was very nicely written to give a directory of the FAT32 partition and 2 executable programs to copy files files to/from the FAT32 partition.

I have only a brief amount of time to use the QLion board, but it worked perfectly on a standard QL.

I have been making some Joystick adapters which work perfectly with the board. Which means all QL connections work as well.

The QLion Silver board looks good as well.


Regards,

Derek

Hi thank you all,

Peter I'll maybe return to a real cpu in the future, your latest qimsi gold is marvelous.
Derek I am very happy it worked well, thank you for the feedback.

Thank you. Your extension slot form factor has the advantage of more robust connectors though.
And the electronics just feels more save inside the QL case.
Also, still providing VGA is nice. Size and heavier connectors didn't allow me a nice VGA solution at the ROM port.

I think both QLion and QIMSI Gold are excellent developments.

I have had to repair some broken QLs to be able to use these two developments.

I will try to get the QL Network running, neyptworking to Q68 and QPC2, SMSQmulator via QLUB.

Hi lliont!
I am interested in getting a QLion Silver card, if it's possible!
Thank you!

Oh, yes - a QLion Gold!
Thank you, lliont!
