The Sinclair QL Forum

As multi-rom boards for the QL never seem to come up on eBay I'm trying to find another solution

I believe it's possible to remove the ROMs and use a modified rom port cartridge instead, but that means the rom port is then tied up

So my thought is to use one of Chr$ excellent ROM boards which I'll fit with a ZIF socket and have it outside the case on the end of a ribbon cable

But does anyone know where I might find a header to fit one of the ROM sockets with a ribbon cable I could route to the outside (ideally it would have a socket on other end already so I don't have any soldering to do) please?

This is the sort of thing, but a plug at one end and a socket at the other:


Many thanks

I've seen cable mounted 'plugs' so a dip 28 with pins, but never seen a socket type. You may have to use a header and a small PCB to achieve this.

One with a plug one end and a socket the other end of the ribbon cable was just me being hopeful

But I can’t even find a header with a ribbon sadly

I'm guessing you mean this sort of thing:

Thanks, but I’ve been a bit of an idiot

I have a couple of Viglen Rom socket extensions for the bbc micro and am wondering if one of those will work in a QL?

Worse case I can cut the cartridge slot off one and that will give me the header with ribbon

Many thanks

I assume QL-SD (with the 512k flash Rom) isn’t available any more please?

Many thanks

Do you mean the QL-SD-ROM from Marcel Kilgus? He doesn't make them any more, but you might strike lucky and get a second hand one I suppose.

IIRC, Tetroid made some form of multi-ROM or ROM switcher device, I hope I'm right saying it was him. I don't remember much about it, and obviously it's not so easy for him to sell them now with the situation in that part of the world.

Thanks Dilwyn, yes it’s QL-SD-ROM by Marcel. Will keep an eye on eBay.

In the meantime I’ll build a spare QL board back up to a bare working machine and see what happens when I plug in a bbc Viglen adapter (don’t want to risk it with my main QL’s in case it causes damage)

Many thanks
