I remember Fire!, just had ago of it again, suprisingly punishing from right off.
My friend had a Nintendo Game and Watch version of the same plot.

thanks for the memories

I just found a promocode for this hotel. Takes it down to £64 for the two nights

ooh yes please, full kit full weekend please.

thanks

The insulator ooze looks normal, it's a usually a factory glue to keep winds and convergence magnets in place. as for the picture, yeah agree, for the focus to go like that sounds like the LOPT. I think the AKF11 is essentially a Philips CM8833 (mk 1), and new lopts are available. (ebay , donberg et...

Hi Mark, I don't know the diodes are bad but if they are, the parts list describe D605,613,615,618 as "EGP20G" but on the block diagram as RGP15J for 605,613,618 and RGP15G. D615 = EGP20G or RGP15G D605 = EGP20G or RGB15J D613 = EGP20G or RGP15J D618 = EGP20G or RGP15J the G seems to be 400v and the...

I just did a reading of the PH601

1 : 0.005v
2: 102.4v
4: -108.8v
5: -86v


assuming i got the right ground...

That's a great steer thank you Mark & Kazzie, When I checked the output from the G board (when connected to A and running) the +15v is stable at 14.98v the +115v is stable at 114.7v and as we know the -15v is -20v and climbs to -18 It'll probably be the weekend before I can check PH601 and the D615,...

With regard to the -23V output on the -15V rail, is that on the power supply board (board G)? And is that with the other boards connected or disconnected? If it's that far off when disconnected, I'd be worried about the T603 transformer, as the only things between it and the -15V output is a rectif...

A very overbright picture may mean that the current flowing through the electron guns is too high. Most CRT sets have a protection system, such that over a certain level, it will shut down all or part of the set. Some protection designs latch and some don’t (so the set may then cycle on and off). I...

I just had a listen and the sound is so familiar . I think it must have been used on pretty much every single kids show back in the 80s.
Anything sciencey , lab, castle, dungeon.
It made me think of Danger Mouse....

I've done a bit more work on this. I've recapped the power board but problem remains.
The board is outputting -23v on the -15 rail so am looking to replace the regulators next.

Thanks for that. It's a good idea for a thread.

ooooooooooooooohhhh baby!!

oh my god it's soooooo quick!!!!

Hi there, My lovely pictured Sony PVM has gone weird. ! Not sure if there are any CRT experts out there but felt it was worth at least asking on here. When I turn on the picture comes on, (a bit over bright) and over about 60 seconds the picture slowly fades to nothing (including OSD bits). I've che...

I was waiting for Dave to say, just put it in the dishwasher....

I'm a bit disappointed!

just in case you were using your AV2 socket - that TV only accepts RGB on socket 1/AV1

from manual

! NOTE
G Signal type RGB, i.e. the signals red, green and blue can only be selected for the Euro scart and the AV 1 can be
received.

This is really nice, nice work.
Begging to be done though.....here's a NULA version.

I just added it to Lurkio's disc img. The file is called N.SPHERE

Acorn RISC PC Launch - 16th April 1994 (Home Video Recording) (via the RISC OS Open forums ) - is that really how product launches were done back in the 90s? :shock: It really is. I was there.

From experience high pitch will be either the flyback (LOPT) on the way out or the power transistor, which on philip colour crts i *think* is a BU508A. The BU508A being quite any easy swap, LOPT a bit more involved, and may as well do all the electrolytic caps while your at it. *always discharge the...

As someone else said, the power switch on philips monitors is flakey (the internal latch starts to fail) and does does like yours is starting to go, you can buy new switches (but require discharge, dismantle and desolder) other people just wedge the switch in with a bit of plastic/lollystick!. Don't...

After Vectoreyes (Adrian) did his thread about his last Exile question and RTW did his screen interpretation of the mapping algo. it sparked my interest. I've always been a bit obsessed with the game and wanted to have a play with is insides. Having worked out in my head how some of it works I've st...

Great catch .....
Looks like the 0-keycap is from another computer...
Feel free to ask questions on the Atom forum.

Looks like Tipex to me

I seem to recall it was the 'moral outrage' caused by Mortal Kombat on home machines that caused film like ratings to be introduced.

Thanks Tom, so let me paraphrase you, the x,y we know because we choose it and the x lookup is only used as a pointer for confirming the what I called 'special' mapped items and their parameters. I'll probably start a thread in Projects shortly for my Exile Editor progress. p.s. Nice to meet you at ...
