how disapointed was i...french mistress!


on a side note.

formatting 3.5 disks

presumably..if format on the beeb

*form80 0
*form80 2

will format a 3.5 disk to 80 track , double sided. yes?

but Oniflop reports - unknown disk format.

now if format on the beeb

*form40 0
*form40 2

i still get unknown format..


if i format on Oniflp as 40 track , double sided 200k . it works a treat..
if i format on oniflop as 80 track , dS 400k - i also works

so omniflop can format the disks , no worries.

some more work on the beeb today, i fitted a volume control to the old girl - granny's garden is just too damn loud!!!!

its a simple mod but the motherboard has to come out, i cheated a bit and left it half in with the psu wires connected and simple unsoldered the volume pot.

i then refitted the board , screwed it back down and soldered in three pins - i wasn't going to do this originally - that why i had refitted the board but i just noticed them in my bits and bobs box so on they went.

i have a batch of 6inch single pin connector wire that i had planned to use on a remote 68000 cpu project , i may still one day but not yet. So this is the wire you see from the volume control to the original resistor pcb holes & the new pins on the motherboard.

result?

i now have full (loud) and all the way to off if i need it...

lovely.

Original volume -

volume turned down most of the way.

As i had the case off , i teased back the brown plastic and put two strips of black insulating tape under the cover , i repeated this on the underside too and then stuck the brown plastic cover back on in that corner. a quick lick with a black marker on the exposed edge of the rom hole to hide the white edge and it looks a little better now. - no hole.

mjn.

If I ever end up getting a BBC, and I probably will, if I keep following this thread, I probably should localize it and put an YLE logo over the BBC logo.

You really are enjoying that machine I see, we should have a go at making an analogue port convertor together to allow std joysticks to be used.
Nice to have the option of using both types then.

How you getting on with the Teletext graphics mode, that is one very differently controlled screen, for example, in mode 7, at the prompt, press shift f1 and watch the invisible attribute take the space on the screen, anything typed then is in red... try the other shifted function keys, and then for real fun try them using the Ctrl key instead of shift....

YLE ?

Short of Yleisradio, meaning Finnish Broadcasting Corporation.

Nice work with the external pot, BTW! Interesting that Acorn has put an internal dial for the volume originally.

@tc I haven't really played with the beeb in any great detail , I've bought an advanced users book and I will sit down and write some programs for it soon. The various graphic modes interest me and I'm sure I'll make some progs that use it.

Well my use so far is frak and the adult version , elite , thrust and granny's garden but the volume of gg at 1:00am last week was a bit much !

And as always my and other peoples projects took over ...

Of course all the interesting add in's for the beeb look interesting...

2nd processor , robotics interface , teletext adaptor , prestel , networking - although I can't imagine the beeb has Firefox yet. - the speccy got a twitter browser tho ..
