Re: Random hardware ideas!

I like this type of discussion. It brings out the pros and cons of ideas very quickly. I do think keyboards and mice are becoming a slight problem. Not huge, but mice moreso. The device I migrated to above can use SPI so it's implicit in that that SPI would have to exist. Since USB might come up oft...

Re: Random hardware ideas!

I commented something to that effect but I may have forgotten to submit my edit ;) FTDI has device and host controllers and the numbering makes no sense. I have an FT122 addressable by a QL and can successfully send it data. In principle it works. With dumb devices like keyboards it doesn't matter t...

Re: Fun things to do with an MC68EC020....

We've been discussing it in terms of two sides of the CPU - expansion side (left side) and QL-side (right side), which is only the QL's unexpanded internal address space. The idea is to tri-state buffer well and often. ;) The SRAM and expansion ports are left of CPU and will be buffered. The QL's ad...

Re: Random hardware ideas!

A new video system. Two parts: ⋅ A video card that contains RAM and a better way of reading it, resulting in a more modern signal like HDMI. ⋅ A new 8301 replacement that doesn't do anything about video, removes that interrupt and just does its other tasks. So, add a video capabi...

Re: Random hardware ideas!

I think the community has a nice way, when a new port becomes available and supported, is they look at what can be plugged into that port, find one thing that is good, cheap and fast *laughs* and standardize around that.

USB would open up a lot of options for people to.... tinker. ;)

Re: Sinclair QL JOBLOT: 127 MD's!!!

The admins have taken no action against him. I don't know why they have this rule but they have never enforced it against him or Rich at RWAP. If you really have a problem with it, talk to an admin. Outsoft is one of the good guys, working hard and spending much time to help the community. Sometimes...

Re: Random hardware ideas!

A proper USB port. Using the FTDI FT245R 2.0 IC: http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT245R.pdf It works well in Motorola systems, is 5V capable, provides USB 2.0 (480Mb/sec theoretical). I'll provide hardware if someone wants to develop the code to run it. The same driver co...

Re: Fun things to do with an MC68EC020....

I already started a thread for these more speculative ideas. It's not my job to police the forums, but I do like threads to stay on topic. Often people post good info on the wrong thread and it makes it so much harder to find and refer to later. For on topicness - Nasta has been even busier than usu...

Re: Announcement - new QL Interface

I'm investigating having an FTDI USB driver IC on the hobby card I'm working on. But then, I'm also looking at the Wiznet hardware stack, separately, to provide ethernet.
