That sounds great! ASIC designs for ST chips for sure, source code for TOS (is it likely to be abandonware now). Also, why did Atari do so many prototypes of stuff that never went into manufacture. Also why the hell did they not go 32bit for the falcon's 030, Assume it was cost cutting on adding a second ROM to make 32bit access to TOS. Similar with RAM. Assume its all down to costs and time scales. I guess if Atari did any more work on the falcon it would have never got out the door at all.

Good stuff, shame people have to sign up again to have the last word, and we are the childish ones. seesh. Nobody needs this BS from people. Myself and others have been working a lot on various things, and such posts of negativity are just from people who seem to have nothing better to do. So leave the real work to the grown ups then I guess as usual. No forum is safe or enjoyable anymore. many agree. I have better things to do with my time than reply to negativity all the time. I don't even bother to read most replies anymore, no point. seems the rise of people going against what I do or say is on the rise. no point posting anything as everything gets spammed to the point that the original post gets lost. Just no point saying anything anymore. Its been ongoing for probably 2 years now, only gets worse. When the so called tech experts go against things I do or say, its just time to move on. I really had enough and don't care anymore. My site and blog will have updates, though at least people can't pollute my stuff there. If people don't like what I put, then bugger off, simple. stay out of my way and everything will be fine.

Awesome find!

Case in point right there. All these types of posts have become so tiresome over the past year its unreal. I mean, I might as well talk to myself these days. Everything I say or do, someone is there to contradict or dispute it. Mostly on 30 year old information, or opinions or speculation, or facts from people about things they know nothing about. I am trying to get to the bottom of a lot of hardware issues and design new stuff, and a lot of the time, I just seem to get shot down for it. Meanwhile I am doing research in 2017 getting results making progress, and what do I get, just BS from people all the time. Then people wonder why I hardly post on forums anymore. I didn't post over on AF for some months, I came back, 2 days later, just lameass comments again. People just don't believe anything I say. I made the whole thing up, or whatever. People say I am posting nonsense, well , all I see is nonsense. Personally, I quit. Its a win win. People don't read my nonsense, I don't have to read theirs any longer. Personally sick of gritting my teeth each day on posts I have read. I was always against those posts which were "why bother" related. Though , case in point again, Why bother. Well I wont anymore. People just have no idea how angry a lot of posts make me with all the BS hype which is posted. Correcting all those people and posts would turn into a full time job, and well, whats the point. Frankly got better things to do. If people want to follow my work, everyone should know where my site is by now.

What cartridge is known to have problems with this kit that you would like me to test ? This is a community project which I helped produce the basics for. Jonathan Whiteside , Thibaut Guillet ( and some others ) did a lot of research into it and his work is published thusfar. I'm sorry if me personally not working on it offends you in some way. I helped those guys out and produced the PCB for them and obtained some parts which are sold in my store. Others are welcome to try the kit, its a BETA, I make no secrets about anything. If people don't want to help, then its their choice. Unfortunately I am only one person and can only do so much per day. Perhaps if there was more people like Jonathan willing to take on some real work in 2017 then things would get done quicker. Should there be a issue, I will look into it needs be, Really don't see why you having such a hard time with this.

Who is "everyone" ? What cartridges ? Where is the research to support these claims ? Where is it concluded that the RTC cartridge is to blame ? Where is the research to prove the "pass through" function is to blame ? "going on the past" may be good to a point, though assuming stuff "back in the day" is going to have same problems with new builds isn't exactly fair is it. Its basically just speculation based on outdated information and "hearsay reports" from people who probably don't know any better. You can't assume blame on the RTC cartridge is something "after it" doesn't work. There can be multiple causes. I doubt anyone has really looked into why things did fail back in the day, if any. If someone tries the kit and it doesn't work, I will investigate it.

For future readers of this thread, please see my blog for more recent activities http://exxosnews.blogspot.co.uk/

A few more entries already http://exxosnews.blogspot.co.uk/ I guess this is more of a "catch up" blog at the moment as there is a lot going on lately.

Awesome Yes I think the blog will make life a whole lot easier for myself and people "following me" Lots of posts planned

Cheers buddy Yes, I'm not going past ST/E machines. I wanted to do a simple booster for the falcon, but while may be possible, realistically, I am just never going to have time to do it Its hard enough to find time to work on the ST boosters, nevermind the zillion other projects on the go. Not only that, after 25 years of doing PCBs, there comes a point where its just not fun anymore. So I really just want to finish off current projects and maintain stocks in my store for the future.

http://exxosnews.blogspot.co.uk/ It has been apparent for some time that scattering my "work" across various groups has become a little "messy". A lot of my posts just get lost or spammed out of context to the point the original post itself becomes "lost". There is also a lot of times I have to repeat myself about the same products I am developing over and over. Its fine for people to ask questions, but this information is already online "lost" somewhere. I also don't have much free time and flicking back on forth across groups trying to keep up has turned into a fulltime job in itself. So I have decided to create my own news blog. http://exxosnews.blogspot.co.uk/ Here I will post recent items I am working on and post all news relating as well. This way, anyone who wants to keep up to date with items can simply look at my blog, even search for the last post relating to what they are asking. Also people can see whats going on "at a glance" . Of course people are welcome to share and link to various blog posts on the groups, I hope people will do that for me and save me some time! This way I can invest more time on hardware dev. Overall I think its a win-win for everyone including myself So if you are interested in my work, please bookmark my blog and subscribe!

Thanks Ron, hope your doing ok

No, you wire it up as a "pass through" type thing.

10R in blue and black. 2.2R in red and black. Though the load resistors were more intended for people upgrading original Atari PSU's.. My PSU's are all tested under load anyway.

It says in my webstore page.. Resistors are simply pushed into the PSU connector. 5V uses 2.2R (loads 5V rail with 2.2amps) and 12V uses 10R (loads 12V rail with 1.2amps). Then you can measure the PSU under the load resistors and make sure the voltages are correct. Note these resistors are rating for continuous use, but get EXTREMELY HOT very quickly. So I suggest not running them for more than 30 seconds at a time.

I mostly did this for "fun" and I wanted a set of purple simms, so I made some With simms getting hard to find as well (at least in EU) I thought it would be good to have something "ready" should demand grow for them in the future

belt driven ? bad belt. clean the heads. bad psu.

If you are going to spend a lot on a setup up inverter, why not just buy one of my own brand PSU's which has 110V option ? https://www.exxoshost.co.uk/atari/last/storenew/#0030 Though you will need to swap your PSU base. John cove does sell them fully assembled if you wanted to contact him for a price. http://www.ebay.co.uk/usr/jaysretrocomputers?_trksid=p2055119.m1438.l2754

I sell upgraded ones , but only 240V types. https://www.exxoshost.co.uk/atari/last/storenew/#PSU

Have a few left of these 060 REV 6 E41J CPU's in my store if anyone is looking for them. All my CPU's I have tested personally at 95MHz minimum and they all report E41J mask (REV 6) . https://www.exxoshost.co.uk/atari/last/storenew/#0056

Monitors vary in tolerance of what they accept signal wise, more modern monitors tend to be more fussy about the ST's video signals. My fix does help to solve such issues. I'm not aware of any damages being done being used in such ways, likely it would damage the monitor before the ST, but modern LCD's I doubt would be damages anyway. Older CRT's if they start flashing black and white a lot can strain and die, though old CRT's generally won't show up the problem anyway. ST's are failing in many respects, they are 30+ years old now, so fixes will have to be done at some point anyway. Grey screen doesn't sound right, there are a lot of cables about, possible yours has resistors added in the RGB lines ? If so, then value could be to high. It could also contribute to odd video problems as well.

If RGB is going out of sync, then it sounds like this type of issue... http://www.exxoshost.co.uk/atari/last/STFMSYNCFIX/index.htm I've had white backgrounds go screwy, but darker ones like the desktop green work fine. Though don't forget the video timings are a bit iffy with some monitors anyway.

The FPGA stuff could be the only way forward. With real hardware failing like mad these days it is at least a alternative. Though it again gets back to another thread about the future of the machines, in terms of new people using Atari ST's etc. Likely they will buy a "cheap" ST and see if they like the games, then they may invest in a hard drive and maybe other things to make it faster such as the boosters. Though I am not really sure if new people are going to spend big bucks on a firebee right off. Its also one thing to have games run a bit faster and smoother, though after that, then what ? Not exactly any games being developed which would take advantage of the speed of a faster system. Of course everyone uses their machine for various things. No way to really generalise anything. Though my hope one day is to produce a booster which will be cheap enough and give enough power that people may want to start coding again for the Atari's. Though that would need mass production and people willing to buy the stuff, though I don't think the Atari market will ever be large enough for that to actually happen.

The best base for this IMHO is the Milan. The guy was working on a 060 version, but never finished it due to lack of demand. Though if that design was updated to even take PCI cards instead of ISA, then that would be pretty much a complete system. I did ask about doing a run of the original milan, but never got a reply about it Annoying thing is, speaking from a hardware point of view myself, Everything has to be re-invented all the time. Also while I do a lot of stuff as people know, I have to do all this work and research pretty much all by myself. There is Rodolphe who helps me get up to speed with how the 68000 bus operations work and helps with with some coding, though at the end of the day, I am having to learn everything from the ground up. This results in endless years ( yes YEARS) of trial and error to figure it all out. I'm not one for just ripping off designs which are already produced, I do research all designs and then do my own design and have stuff working how I want it to. So this in itself means even more work for myself. As already mentioned, there is a thread on atari-forum about it. Though there is no where enough active hardware development people to do much past what is already been developed. I've talked to a lot of people about problems I have with various stuff, nobody has a clue what I am talking about, so nevermind anyone being able to actually help with development of stuff. It's not just that though, again its software, the more hardware changes, the more old software breaks. Its why I am trying to max out the 68000 series of CPU speed wise. The 030 adds a nice boost due to caches, but even so eventually you hit a wall of raw MHz power. Even with fast-ram, it makes a fast system, but I don't know what the solution is after that. I myself while I do a lot of work, I won't be doing stuff indefinitely either. Unless more people start learning how to solder and learn how the 68000 systems work, then I fear in the near future there will simply be nobody left producing new hardware at all.
