ST Real time Clock beta boards

RTC_store.jpg Like a internal "forget me not clock". These boards have been done for a while, but I have not had chance to test personally or write install docs. Though this work has been done for me by Jonathan Whiteside. So as people have been bugging for these for ages, I threw togethe...

Re: New "exxos style" Falcon PSU coming soon

exxosfalcpsu.jpg I know people are still waiting for these. So much going on lately just progress is really slow. Transformers arrived yesterday. I have a lot of soldering to do yet though. I've tested about 30 boards so far and all working. So once the connectors are soldered with the transformers...

New production of STE 30pin simms.

I personally have got tired of hunting around for 30pinn simms for the STE. So I designed my own. 18222519_10209514575796949_6645816888172709426_n.jpg I designed these for myself mostly, though if there is interest I will build some batches up. Price would be around £25-£30 a set at a guess. My prot...

Re: Feature Requests

Hi, I finally looked at it. Steem doesn't hack system variables for the 14MB hack, it just hacks the MMU's 4MB limitation. It makes sense because TOS tests for more than 4MB using R/W/bus error, which I didn't know before yesterday. :) So TOS *is* capable of seeing more than 4MB ST-RAM then ? As in...

Re: Falcon Clock Patch

my CT60/ CT60e runs perfect with my mod. It solves the noise on the clocks and buffers them. The MEGA ST had exactly the same problem and solved exactly the same way. I really don't care what other people say, or what other sites say. We need to move forward with current research not get lost in hal...

Re: Falcon ST-RAM 14MB boards

Everything worked immediately! Excellent work! Thank you very much :) :cheers: Yes, new connectors are ...

Re: STE BOOSTER V1 32MHZ & FAST-TOS

I did mention about it some time ago. What I have done is produced a new board (waiting for prototype to arrive) which is the same STE booster circuit, but totally re-done to allow a plug-in type solution. This one will plug into the CPU socket. I have had some custom spacers made which will replace...

Re: Axial 4,700uF replacement prototype board.

You seem to not know about all the bad caps found these days in the old psu, and on the motherboards the issue start to show too. And it is a bulk capacitor, meaning it's role is important in powering the computer. People wanted this solution, I did not force it on anyone. Then I get shot down by W...

Re: Axial 4,700uF replacement prototype board.

It sounds like computer version of AudioVooDoo. Caps made in 80's & 90's still have better parameters than new ones. If you REALLY !!! want to replace caps why dont use a one that doesn't look wired?? W. *sigh* So capacitor technology obviously hasn't improved any in the last 20 years. Please r...

The board I stated in the first post, will replace all the 4,700 caps in any ST, STE,MEGA, Falcon etc. Producing that value in ceramics isn't realistic.

Re: Overall strategy for hardware mods, upgrades, clones

All of these projects are awesome. I would be all about buying your boosters, but trying to figure out if they keep enough compatibility (I'd think so since they are switchable) to be worth it for me who owns almost the full line of STs. Even on top of that, I own a MiST as well. Each hardware chan...
