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...

Re: Random hardware ideas!

A backplane like mPlane, but doubling over in front of the QL. This would make a handy armrest. In the middle of winter you could also warm your fingertips on the forest of little heatsinks.

Wanted: Issue 7 QL PCB.

I'm looking for a UK or EU spec Issue 7 QL board. It can be the bare board, no ICs but it does need to be functioning/working. Please make offer with shipping to Texas, 78664. Slow shipping is okay.

Re: Random hardware ideas!

Well. Hmmm. With what I have been graciously handed by Nasta, Peter Graf and Silvester, currently we have the following complementary options that fit well together: Ethernet:- CP2200-based. 10Mb/sec full duplex. Non-existent driver would be loaded in RAM. QL-SD:- 2x SD card slots, driver in ROM. Co...

Re: Random hardware ideas!

Best to forget using MM58274C, the SGC/GC uses a triple lock to prevent corruption (write to 3 addresses each and every time you need to write to a register). Whereas DS1374C uses I2C link, with bonus of integrated crystal and charger, making it much simpler. Downside, only appears to be available ...
