Re: QIMI Interfaces

They are a good choice and last a hell of a long time - I have resurrrected a couple of Z88's in my time, and only had to change one supercap that had started to leak excessive current, making the standby time on the Z88 much shorter.

Re: Life Saver

I wondered what that was a picture of! Fascinating reading. I think you are on to something - I often think of the human body like a finely tuned vehicle - it's all good to start with, but you start to get corrosion, rust and parts begin to wear. The interesting thing here is that the body does rebu...

Re: RGB to VGA

Ok I will shut and go away. :lol: I did search but didn't see that thread. There were some recent discussions about old monitors going bust and not being able to use VGA hence my post when I came across the board. I suppose it is a lot cheaper now for a while until VGA starts going obsolete. :roll:...

It there is an empty OPD case (the bit that houses the keyboard) I could give it a home ;-)

Re: Replacements for Zx8301 / Zx 8302 / IPC

sadly the QL's serial ports are best considered rudimentary at best. I certainly wouldn't chose to add external keyboard through them. Could you elaborate? :? In my world if an rs232 passes bytes it works and a keyboard would pass bytes across it. I could try - serial comms (RS232) is provided by S...

Re: Today I Received...

My main interest is in porting the functionaliity to a propeller chip Does that mean a different chip pin compatible? I would design the software correctly for the new chip rather than repeat the mistakes you might as well make new ones and be in the position of having the ability of correcting the...

Re: Replacements for Zx8301 / Zx 8302 / IPC

Replacement / improvement for the IPC that offers USB or PS/2 Keyboard support, but maintains the internal keyboard functionality. Couldn't one of the serial ports be used for a PS/2 external keyboard? It would only require a bit of software to act as a driver passing the keyboard input to the oper...

Re: Today I Received...

Hi Pr0f, The point I was trying make was that Laurence Reeves has already done the work to debug the 8049 in the QL, so maybe a request to Tony Firshman to release the source code to Hermes would help. I will contact him and see if this can be done. I would certainly like to look at it if it is rel...

Re: Replacements for Zx8301 / Zx 8302 / IPC

It seems the 2 biggest wants would be: Replacement / improvement for the ZX8301 Replacement / improvement for the IPC that offers USB or PS/2 Keyboard support, but maintains the internal keyboard functionality. I doubt that modern external keyboards for the original QL mainboard are a big want. The...
