UFO by P Vernon. Published in Popular Computing Weekly, 23 September 1982, page 19. This magazine clipping only survived because it has a BBC listing on the reverse side! A higher resolution scan could be provided.

Re: Cumana CS400 switchable drive - noises and disk errors

Thanks to his innate kindness (and I strongly suspect my ineptitude :wink: ) Kazzie has kindly offered to look at this drive for me.
Thank you to everyone that has given me advice on this.

Lee, I wondered the same.

Somewhere in those boxes of clippings I'm cataloguing/scanning there's a submission by an Ian Bell. Not necessarily that Ian Bell of course.

Hi Mark, and thanks.
The multimeter is a generic type, model G-44 but I think that's pretty meaningless. I've attached two photos.

Thanks for the reply. I seem to be getting a reading on every pin of the TD63503P from the bottom output pin of HS with the multimeter in resistance mode.

Re: Does anyone remember this adventure game?

But I bet it's Dragon Adventure by William Stott, which I've never played but it ticks all the boxes: there's a dragon in the title, BLOW HORN is in the solution and it's for children. Unfortunately it's missing from the archive and the screenshot on CASA is the Archimedes version.

You have to blow a horn in Level 9's Saga of Erik the Viking and there's also a dragon in it.

Re: Cumana CS400 switchable drive - noises and disk errors

Thanks for your time and patience. This multimeter has crocodile clips and even though they're quite small it was impossible to touch the pins in isolation. Once I'd put pins in the clips it was slightly easier but still not a doddle! However, here are the (hopefully accurate and meaningful) results...

Goldstar black and white portable television

Model BIR-2050. Works but not the best cosmetic condition and a bit grubby from storage.
Offers, or maybe a swap for something interesting? It'd have to be a swap for something small as the reason the tv has to go is lack of space!

Re: Cumana CS400 switchable drive - noises and disk errors

Thanks for the reply and information, Kazzie. With the HS jumper removed the solenoid does not move. The disk spins and the beeb reports "disk error". When the jumper on the MS pins it behaves the same as when it's on HS, i.e. bouncing up and down with the same pattern. The disk spins, "disk error"....

Hello again. Well, the shiny plate isn't obviously removable and I can't tell if the head is moving. Photos are attached - one from above, and one of the model number. It's an Epson SD-540. I removed the sticker to see whether it was covering over a different model number, but it is blank underneath.

Thanks for the replies. 1. The disks are variable in quality, from a quick visual inspection, but nothing you wouldn't have at least tried in 1983! 2. It doesn't give an error code as such, just "Disk fault" when trying to execute a file. *CAT returns a list of files. 3. This drive is different! Lin...

What a beast this is. Apart from a schoolmate in the early 80s that had 8-inch floppy drives rigged up to his BBC (down to his dad I assume), I don't think I've ever seen such a monstrosity.
