Re: Needham EMP-20 Device Programmer

Hi, thanks a lot for that. That is very confusing, I have tried a couple of 5.5 x 2.5 plugs and neither fit. The problem is that the plug will not fit into the socket. Mmm, just tried another plug (wrong voltage PSU, but just to see if it would fit) - and it DOES! It seems that the 2 other 5.5 x "2....

Hi,

Thanks for the tip, I’d prefer a smaller enclosure, but may have to compromise I guess

Wanted : External 3.5" FDD case (only)

Hi,

I am looking for an external 3.5" floppy disk drive case, could be from a Beeb, Atari, Amiga etc. Cumana made quite a few versions. I just need the case to put an existing drive in, no drive, PSU, or cables needed

Re: OPUS 5802 5 1/4" Disk Drive

Hi, thanks for the tips, but all sorted now :) It turns out that the data cable that I was using for testing (not the one that's attached to the case) is faulty.

Re: OPUS 5802 5 1/4" Disk Drive

Hi,

ah, I hadn't appreciated that side 0 was the bottom head, so, I can see that it must be a DS drive. If one head is not working, then I guess there must be a fault on the drive. I will try cleaning the upper head (again), but it seems that the drive may only be partially working

Hi Mark, yes :D I can't see any wires going to the bottom "head", though there does look like there may be a head embedded in the ceramic, it looks like a single bit of metal - no tunnel erase heads, it does not look like a "real" head, so it may indeed be SS. There is no manufacturer's name on the ...

Hi Rob, thanks for the input. I did wonder if an Einstein fault could be the problem, but the RGB analogue output works fine into the SCART RGB input on my TV.

Hi Mark, yes, that should be possible. The monitor has inputs for TTL and Analogue RGB, I just need to make up more cables to take the output from, say, my Memotech FDX or BBC to the monitor. That's the easy bit, then I need to work out what to do to try and fix the monitor :) Thanks for the suggest...

Re: Acornsoft Master/2P C compiler

I think that it will probably be much better when the pages are split. Acrobat tries to square up the page when it does the OCR, two pages with different slopes are a bit too much for it.

The number of pages put me off splitting and cropping too :-)
