Sam PSUs
Wandering down the Lower High Street in Cheltenham, I bobbed into 'Hardings', an Electrical Shop. There, before my eyes, were two Sam Power Supply Units. They were 8 pounds each, and got the SAM PSU sticker on top, and MGT sticker on the bottom. I didn't buy them, so they were still in the shop, yesterday... Tim W.

I'm interested in one psu, but i have a small problem: i live in italy -) May i ask you to buy one for me and then send it? I'll pay everything! If you are interested in trading SAM stuff i have some original spare manuals. Thanks, Bruno

I'm interested in one too - my original SAM PSU has been damaged for ages, and it'd be nice to have a working one. I'll give them a ring when they're open, and if they're still available I'll mail one on to you... Si

Ok, how about I pay for it and arrange for collection? Great! How can I pay for it? Oh, just cash or cheque? Pants. If anyone in the area fancies helping out, please e-mail me off the list! Si

I'm happy to believe this - also I tried it on my machine at home and it was actually worse so I figure it has to be a SimCoupe problem. I use 100Hz for my monitor refresh, which means 50Hz scrollers look pretty good most of the time. I use 50Hz :) Might be worth having another go at sometime... IMO yes, definitely, if you want to be able to claim 100% accuracy for SimCoupe. If the worst came to the worst, being able to support it in win98/2k/xp and failover gracefull on NT would be better than no support at all :) Still a fantastic piece of software though :) G

I didn't think modern monitors were happy running at such a low rate though? IMO yes, definitely, if you want to be able to claim 100% accuracy for SimCoupe. I can butcher a quick version for you to try if ya like...? Running with 50Hz monitor sync on a fast machine /should/ just require a single forced sync after every emulated frame. If the worst came to the worst, being able to support it in win98/2k/xp and failover gracefull on NT would be better than no support at all :) Indeed - as is the case with joystick support and NT4 :-) Si

I didn't think modern monitors were happy running at such a low rate though? Uhh. I dunno, I just went into the settings in the display properties, changed the refresh rate to 50Hz. :) The monitor reckons it's actually 50.2Hz though :( On my matrox at home I played with the settings (you can do some pretty cool stuff in the Advanced area to things like the flyback time etc) and got it so that the monitor said exactly 50Hz, I can't figure out how to do that here. Both this SGI monitor and my Belinea at home seem happy enough, although I wouldn't subject them to it for long periods. Having said that I guess I'm probably not representative, the Belinea is -very- nice (.24 dp?) and you'd expect the SGI kit to be able to handle weird stuff. Strangely, I can't select 50Hz for 800x600 on the SGI though, so I have to run in a window at work :( I can butcher a quick version for you to try if ya like...? Running with 50Hz monitor sync on a fast machine /should/ just require a single forced sync after every emulated frame. Cool! This machine is pretty solid at 100% in sync-enabled, and ranges between 170% and 290% with sync disabled, so should be quick enough. As an aside but still wrt simcoupe, do you have any plans to implement any sort of debug facility (so you could pause the emulation, take a look at the registers, disassembly of the code, step through etc etc)? If not would anyone else be interested in using something like that if I wrote it? :) G

My Mitsubishi monitor at home seems to report/ignore invalid rates, so hopefully it'll either complain or just work. The monitor reckons it's actually 50.2Hz though :( That's pretty close, and the only problem you might have is with sound. SimCoupé buffers just enough to allow small speed fluctuations, so it'll be fine most of the time, but once it's too far out of step it'll need to drop a frame's worth of wave data to bring it back in sync. It'd be better if it ran slightly under speed instead, as generating extra SAA samples to fill the gap would be guaranteed seamless. Of course, BEEP and DAC output would still suffer the occasional click though. Cool!

Ok, I'll be in touch off the list about this... do you have any plans to implement any sort of debug facility (so you could pause the emulation, take a look at the registers, disassembly of the code, step through etc etc)? Yuppers, and it was actually something I was working on last night! I'm pretty much done with the changes needed to suspend execution part way through frames, to handle single-stepping and breakpoints. The new disassembler had already been done, and I've most of a mini-assembler completed too. There's actually a TurboMON-style mock-up in SimCoupé 0.82a - press '/' on the numeric keypad to show a quick code/register dump at the end of each frame. The new version won't look anything like that tho, fortunately! Si
