Thanks for the feedback folks, I tend to go a bit overboard with the photos on these write ups. Most of my stuff is arcade PCB repairs but this one might be of interest in Atari land, a work in progress but the end is in sight. http://www.retrocomputermuseum.co.uk/forum/index.php?topic=3211.0 @ Arne...

Re: Mega ST floppy transplant

Yes, I did this a couple of days ago and it worked perfectly, nothing on the drive needed to be changed, it just drops in and works.

Oooh thanks, could you take a photo of the floppy end tho, I seem to recall there were a load of different floppy eject button configurations, but if this is the right one I will definitely take you up on the offer.

Re: WTB: Atari 1040 STE - Australia

I culled my collection a while back so have no spare STEs anymore. You wouldnt happen to have an STFM case going spare would you? Its a long shot but there are not many Atarians in Oz these days, I think the Melbourne Atari Club folded back in 05, not 100% sure tho.

Re: Are there any religious ST games?

Re: Philips CM8833 colour monitor problem high pitch whine noise

Trouble with paying for someone elses time with this retro gear is that the final bill will far exceed the replacement cost of the unit, its barely worth repairing due to the cost of the replacement part, so unless its in especially good condition or is considered an old friend it is never going to ...

Re: Philips CM8833 colour monitor problem high pitch whine noise

Yes it could well, depends on which taps are shorted and what effect it has on the main power rails. Another issue with the commodore monitors is that the power switch is actually 2 in one and often one side dies so part of the monitor isn't getting powered up, worth checking too.

Re: Philips CM8833 colour monitor problem high pitch whine noise

They are not that expensive or hard to come by as you might think, especially if you factor in postage for any new monitor purchase, far cheaper to ship a 250g LOPT than a 5Kg monitor. CM8833s are usually the same chassis as the Commodoer 1084 monitors and the most common LOPT for thoses is HR7533 w...

Re: Sparky / Pompey Pirates - Quartet Tunes

Does anyone know if there is way to get these files back into the full Quartet app rather than just the player? Would love to be able to fiddle around with them. Quartet just complains that the playback frequency has to be between 4 and 16KHz, then crashes with 3 bombs.

Re: Techie RAM question.

Lots of useful info at that site, I didn't want to modify the motherboard but I did find the service manual which explains how the memory management chip works on boot up, that info plus the rear edge connector pinouts allowed me to build this puppy! http://womblesretrorepairshack.blogspot.com/2008/...

Re: Techie RAM question.

Quite possible. These machines does not have a proper memory management system, so it's up to the individual game to properly detect any expansions. I dont know how it compares to other MSX machines but it does seem to have a degree of intelligence, there is a custom Yamaha memory slot controller c...

Actually I think you are right, oddly enough I have a collection of magazines from the early 80s in binders that show many machines stripped down and it states that this machine has 48KB, but if 16K is video RAM then that would make sense as I have seen other sources say this machine only had 32KB. ...

Interesting, if you have an eprom blower as I do the whole SRAM option is harder work than just blowing a new rom, especially as you somehow how to load the SRAM with code while its insitu. Could prune back that cct to support a standard rom easily enough. Thanks for the link!!
