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....

Re: Needham EMP-20 Device Programmer
Dave I realise that this is quite an old thread and your devices are long gone. However, when you posted the ad, you said . . .

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
regards

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. After I cleaned the heads, in "clutching at straws" mode, I readdressed the drive as "2" and found that it worked perfectly in DS mode. In...

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 ...

Re: Tatung Einstein TC-01 with TM-01 colour monitor fault
Well, I have confirmed that it is definitely the monitor that's faulty.
Taking the RGB output from my BBC Micro into the monitor's TTL input displays the BBC Micro boot text in blue !

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.

Re: Tatung Einstein TC-01 with TM-01 colour monitor fault
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
