The 30th anniversary of the launch of the ZX81, along with the BBC 4 programme Electric Dreams has had me pondering... which prompted me to write a blog item. http://www.lingula.org.uk/wordpress/2011/03/06/fun-basic_required/ Comments and discussion either to the list or to the blog are

[Ql-Users] QL replacements - state of play...

2011-03-11 Thread Dave Park
Hi all, So here's the state of play in designing new QL replacements... Peter Graf is bogged down with some issues on his board. It has a decent spec but it doesn't currently work in a meaningful sense. He has various obstacles (working alone) that mean his design will be delayed or not

Well it wasn't as bad as I had feared, but not as simple as I had hoped. And I'm certainly not going to mention the still unsolved mystery of the mm.alchp vectored call that reported success but actually zeroed out an entirely different area of the common heap, thus trashing the in-memory copy

Yes please. I'll do the driver. :) How about a board that plugs into the ROM port and has the necessary logic to implement the four wire SPI interface for a single slave device (namely the USBWiz). The board would also have a header socket to mount the USBWiz module on. Job done.

With a USB/multi-card reader, it should be possible to create a QDOS file system on a Compact Flash card. I've scrounged about 13 512MB CF cards that are no longer needed at work. I can send them to someone in the UK if someone can use them. I also have two unopened boxes of TDK ED disks

Dave, That's all very nice and would be an absolutely fantastic piece of hardware but it's very complex and likely to be expensive. I would have thought that a better use of the development cost and time would be an FPGA-based QL clone running at 80MHZ with 1GB RAM and onboard USB3, SATA and

I am just wondering how big or small this project would be, not in terms of time and mountains to climb, but physically. I would like to see it fit inside something like a QL, Amiga, Atari or even laptop style case just for the hell of it. There is a difference between a system you can shove

I was thinking standard Eurocard sized - 160x100mm - the same size as a normal expansion card. It could me as small as 75 x 75mm depending. Dave On Mar 12, 2011, at 1:28 AM, Lee Privett lee.priv...@gmail.com wrote: I am just wondering how big or small this project would be, not in terms of
