QL doesn't work: black screen

[Bubu]

I am very 'conservative' with old computers as I like to respect as much as possible the devices in the same way as they were designed. And the QL was designed to be working with microdrives It's the essence of that computer.

Anyway I'd like to understand what a 'QubIDE clone' is. Is it the same as a divIDE for the Spectrum?

[Mr_Navigator]

It is a hard drive adapter, however current technology what it is means you can get flash card drive equivalents to go in to the QUBIDE port.

Ah, so I don't need to modify the QL, only to plug it to a expansion port, correct?

I've been looking that Jose Leandro (from Spain) has developed a QubIDE clone, I'll try to find out more about this

I'll read this:

Yes, that is the one, it also has a 512k ram expansion built in

Ye as far as I know. I just got one from José although haven't tried it yet, it looks good. There is a thread for this elswhere http://www.theqlforum.com/viewtopic.php?f=2&t=566

HAhAHHhEhEHeHhhehh!! I must put the leds now and I'll have this QL at 100% working order.

A certain persons white based QL could benefit from some white rectangular LEDs though, no names mentioned

Eeeeee, it has some!



Bubu you find the more you get into the QL, the more you will see its rich history of tinkering and lots of expansions, upgrades and addons.

I stand corrected and here here

Now, as long as you aren't that bothered about precise accuracy or the original QL, you could choose alternative LEDs to put in your QL machine. In 1983/84 the choice was limited Red/Orange/Green rectangular.

Today you can get Yellow, Blue & White rectangular.

I think you will find that rectangular yellow LEDs were available in the mid-1980's.

LED technology is continuing to develop better, brighter LEDs. Did you know that there are two ways of making white LEDs? One is to have a non white LED shining light onto a phosphor that when exited by non-white light, gives out white light. The second is to have a red, green and blue LED and to diffuse and mix the light which results in a white light.

I know what you mean, however in my experience where I worked we ordered Yellow LEDs from some suppliers and Orange from others (RS components, Farnell and sometimes Maplin etc.) they were always seem to be Orange and not Yellow per se.

Here are LEDs that can create all colours but not rectangular, 4 leads and very cheap.
