Re: Sinclar QL not working

It looks like your PC may have a memory fault or logic fault related to memory.

Read this thread first: viewtopic.php?t=502

If you are still stuck or overwhelmed there are a few good people who you could send it to for repair.

Re: Random hardware ideas!

More random thoughts (I think you may have opened a Pandora's box Dave): Could do with a prototyping PCB for ROM port, if enough are produced it could help with cheap DIY projects (soundchip, etc). Maybe with a fixed PAL to provide simple I/O facility to prototyping area (ie. using address lines fo...

Re: New to QL. Wanting to write from QL to SD (type) card directly.

Rob, It's not plain sailing developing the card and there are some issues to overcome. There are a few GREAT QubIDE clones - one has floppy controller, IDE adapter, Compact Flash socket and 1MB of SRAM on it. If you can find one of those -- it is listed in a thread in the hardware section -- you sho...

Re: New to QL. Wanting to write from QL to SD (type) card directly.

No, sadly, I just have one broken RomDISQ and one bare RomDISQ PCB. RomDISQ will also not work with QL-SD.

I think QL-SD is a much more elegant and flexible solution.

Re: Wanted: Issue 7 QL PCB.

The 400 odd mdvs are yours already. :D I just need to get them boxed up for international shipping. That's more difficult than it sounds. I need a UK Iss. 7 PCB for testing compatibility of expansions as all I have are Iss. 5 UK and Samsung US boards, and the Iss. 7 board is quite different. I'll ha...

Re: Random hardware ideas!

From Dave not adding Flash, in order to do that on the "Super Duper Gold Card", I concluded the recently discussed card was not the "Super Duper Gold Card". And I was assuming the 680>=20 CPU card and the "Super Duper Gold Card" mean roughly the same. Both might be wro...

Re: Random hardware ideas!

Will (Flash) EPROM be there? No. I'll have to save working on that for the Super Duper Gold Card* But that would make the card dependant on loading the SDHC drivers from microdrive! Or dependant on a second extension card for mass storage with feed-through QL bus. I would at least add a cheap littl...

QL-SD will also be available soon as a QL external expansion card. It'll allow the use of faster and cheaper SD cards instead of slower, more expensive CF cards.

Re: Random hardware ideas!

Will (Flash) EPROM be there? No. I'll have to save working on that for the Super Duper Gold Card* As for the 'non-existent' ethernet driver, and 'easy' USB HID driver: The former has at least an existing, tested hardware to be developed on. It's a chicken and egg situation. If it is available and s...
