Afternoony Zetro, I did try that last night. But you do end up with over 6MB of chaos to trace through. Maybe an Action Replay #4 (a1200 version) and/or WinUAE debugger would be easier. Paul.

I've noticed if the CDROM ribbon (CN17) is disconnected there's NO boot delay before the Kickstart CD ANIM screen to suggest any cdrom device module(s) or [kickstart Gayle IDE] have failed query during early boot sequence. Maybe the cdrom is a totally custom independent unit. (nothing listed in...

Slightly random addition. Slightly random addition. My miniature UHF Video Transmitter (ASTEC UM1233) made from a spare (modified) Sinclair Spectrum 48K RF module: http://www.youtube.com/watch?v=Kjnz7mOPIRw :lol: Never got round to including the sound; sourced separately in that video. Just...

I don't know if you've inadvertently made a typo, but the HSYNC and VSYNC are the wrong way on that bit of Amiga board. Should be: VGA Pin 1|2|3 RGB (6|7|8 GND) Pin 9|10|11 Sync GND Pin 13 H Sync Pin 14 V Sync Amiga Pin 1|2|3 RGB (16|17|18 GND) Pin 11 H Sync Pin 12 V Sync What have you...

Sorry if my explanation seemed incoherent. Let's clarify. It's a multiscan monitor, you're removing the existing 15/9 way connector and remapping to an Amiga's 23pin Dsub type? So your key pins are going to be Horizontal/Vertical sync, R+(GND*)|G+(GND*)|B+(GND*), that I assume the...

I assume the composite sync pin 4 to Amiga pin 10? If you're disconnecting the RGB and the Amiga's composite colour returns, you must be nuking it within the video hybrid as the composite is CVBS which is generated within the Amiga video circuit from a blended signal. Your RGB cable must be...

So collectivity you get monochrome, would imply the RGB are canceling each other out? :wooha: When you say 'tint' do you mean subtracting individual R G B elements produce the collective of the connected. IE: -R=G+B, -B=R+G. Are the monitor pins 1,2,3 (signal) and 6,7,8 (return) (GND) wired...

Sounds like the poor bugger is just about hanging in there, seems very temperamental. :( If the entire image appears bias (SCREEN) to RED, then perhaps your GREEN and BLUE are drifting. Maybe disconnect the R G B s individually from the neck board and see if each work and meter them. Check the...

Maybe 'stedy' can help you: http://www.ianstedman.co.uk/Amiga/designs/Floppy_Adaptor/floppy_adaptor.html Sold out at the moment, though perhaps something to look forward to. You could use his schematics :ninja: and make your own :D. The Pc drives he has listed are about 15UKP on Ebay too. Skippy.

As your Focus/Screen are part of the flyback and the blurriness resolves and stablises after a period of warming it's probably your best starting point as rkauer stated. (High voltage, dividers network, [fluctuatations of focus and/or brightness], Epoxy breakdown). Here is a .pdf manual from...

Also, try and locate where the noise is coming from, if it's not from the SMPS, check the filament (F1/F2) (*heater /electron gun) for loose partials (coating oxidisation (age) (aubible noise) ) or see if there is any visible warping to the grids (G1/G3/G5) causing shorts (visible frame...

Sorry to hear of your bad luck. The "interference" or *lines you see are most likely the retrace (flyback) [slightly slanted]. Be careful adjusting (over ramping/probable cause of sound) the focus (G1-GRID & G4) and screen (G2) as you'll induce potential damage (stress) to both the electronics...

@Zetro: I'm very well, thanks. Look forward to reading more about your 4mb simm upgrade. I'm sure you have all the bases covered, if you require any support or bits n bobs just holler. :thumbsup: Where do I leave a Paypal deposit on a prototype, hehe :p Take care, Paul.
