I will post up some more updates this weekend - I have a keyboard map and a few other bits to upload.

Other projects and a 3d printer have taken my time at the moment, so work on the OPD => QLish device have stalled a little.

Here's an OPD (or rather, Tonto) update:

Mine now has a PC PSU/Video adapter with a scart plug on the other end. I also took everything apart and cleaned it all very thoroughly. And it works, I can go through the menus, all is good.

I have 4 original mdvs with it and they seem a bit shaky (so is one of the drives).

My next mission is therefore to attempt to make back up copies of the original software and save what I can. They have obviously all been re-felted. It appears that is possible on a QL running Dave Walker's OPD<>QL Interchange software.

So wish me luck (and pointers/ideas gratefully received).


Collector of original and some newer QL related computers, accessories and software even though I don't understand how any of them work.
Original BBQL's: 3x German, 1x UK model (plus quite a bit of other old stuff)
Custom AT cased QL system with Gold Card, Qimi mouse, Hermes and MFM HDD
PC with QXLII card installed
Q68 also present

Ask me about near NOS re-felted good quality Microdrive Carts - many available.

I still have my OPD in the cellar. Unfortunately, I have modified my CUB (formerly used with the QL) to work with the OPD, but I can't remember, what I have modified to reverse it.

But you could use the CUB with the OPD to test it out? That's 2 OPD's in Germany then at least, there can't be many.

I've just been making backups of the original OPD cartridges using Dave Walker's OPD/QL Interface software and it all seemed to work - it read and copied them to new carts and reported no file errors. I just need to dig out the OPD now, set it up and then verify that the created carts work on it.

Me not, I am lucky, that my XChange in the OPD works ;) Are the OPD and Tonto ROM packages identical?

@Chr$:
I also have about six MDV from Dave Walker but have never used them, I think, they must be re-felted. I think, this is also software to read OPD cartridges on QL.

Yes, the two ROM packages are the same - not forgetting the Australian Computerphone version too!

Not me - I have a couple of those for sale on sellmyretro though - https://www.sellmyretro.com/offer/detai ... pack-32276

Those were supplied with the original machines - there was a more useful 4 slot version too

I have an OPD disk interface here which is always useful - unfortunately, it does not recognise the disk drive at all, so it has a fault somewhere on the board.

Does anyone fancy having it to see if they can fix it?
