Ikon Ultra Drive

Post by Pernod70 »

Does anyone actually have the Ultra Drive that's in the archive at http://archive.worldofdragon.org/index. ... ltra_Drive

I'm interested in knowing the model number of the actual tape unit used in them.

Similar units were available for a few different machines, including BBC and Nascom, but these were known as Hobbit drives. The Hobbit was advertised as 100K capacity, whereas the Ultra Drive was 200K, so presumably different tape units used.

The Ultra Drive was also advertised as coming soon for BBC, Electron, C64, etc. but have so far only found evidence that it existed for the BBC.

I need to take a look, as I think I had more pictures of it.

Sadly, the owner did sell it long ago. Maybe someone from the forum got it?

I'm afraid I cannot find the pictures of the drive mechanism :(

Hopefully it's current owner will eventually see this. Presume this is the only unit that's ever been seen?

I'm currently emulating the Hobbit drive for the Beeb, and MDCR for the Atom, both use the same tape unit which is already emulated for the Philips P2000T. If I get these two working then I'll see if the Ultra Drive ROM works with the same tape unit.

The Ultra Drive advert vs. the Hobbit advert clearly indicates the Ultra is faster and has double the capacity, so suspect it's a different tape unit.

Yes, it’s the only unit I’ve seen so far.

I tried to use some tapes but wasn’t able to “format” them, so probably the unit needed some service.

Just catching up...I have one in storage, been there for quite a few years, so if it's not mega urgent I should be able to get it out and take some internal photos

Excellent, whenever you can it's mainly the tape unit that needs identifying.

Here are some photos of the insides - only 2 labels that I can see so hopefully they can help you identify the drive model. I have some tapes for this and they are all 30min tapes if that helps.

I'm surprised there's no obvious model number anywhere. Your photos look remarkably similar to one that I got from a Hobbit owner, especially the one with serial number and large cog. So maybe they are the same tape unit, difficult to say.

There's a technical manual for the MDCR at http://www.nascomhomepage.com/pdf/mdcr.pdf. On the last page is a layout of the circuit board, would you say this matches yours?

Yes - connectors and ICs are all in the same place...so I suspect its the same drive......
