Re: -5v - from an ATX psu?

NIce... Here is more info on the Ian Stedman stuff... including a github link with all his schematics. http://www.ianstedman.co.uk/Amiga/designs/Amiga_ATX_Adaptor/amiga_atx_adaptor.html I distinctly remember creating -5V from 5V with a 7905. I can vouch for Stedy's adapter. I have it specifically f...

Re: Atari TT030 Revision Guide

I´m sorry, but for quite some time I won´t take´m apart again. But if it happens in any future, I´ll be thinking of You... There are some pictures yet - I apologize for their bad quality (don´t have a better camera): Thanks! Main takeaway is that this model actually exists. I shall update the guide...

Re: Atari TT030 Revision Guide

Astounding effort. Boah! Chapeau! " where is REV B? I assume that as REV B was about to go into production some last minute changes were done that warranted the B1 designation and REV Bs were never manufactured." Just one remark: I own a daughterboard-TT telling on it´s tin side: C300720-001 Rev B ...

Re: TT030 C302406-001 REV H

Mine (REV.C - PGA model, C301763-001 REV A): Thanks! According to https://coil32.net/online-calculators/inductor-color-code-calculator.html "LD01" seems to be 10uH coil. They indeed look like caps: https://www.partco.fi/en/electronic-components/passives/coils/axial-inductors/12970-kelap-10u.html :c...

Re: TT030 C302406-001 REV H

My eyes are pretty tired after I tried to figure out what is that quite big light green resistor located at near PSU connector and c120 capacitator :shock: :lol: Is that 10ohm resistor? I'll soon try to bring life to TT that has some components missing and that resistor is one of them. Yeah, you ha...

Re: Agranlunds TF534 Build

I build EmuTOS with -m68030 -DSTATIC_ALT_RAM_ADDRESS=0x01000000 The biggest performance boost comes from letting it know about fastram at compile time, this allows it to put a large chunk of its internal variables there instead of in ST-RAM (the Vampire V2 + V4 optimized builds do the same thing) I...

Re: An Atari ST HDMI All Resolution Solution??

I just have an issue with the pricing. Clearly this is a "re-badged" product from Ali Baba

Same packaging even:

vs:

Cost max $3.99 per unit. Shameful ripoff, I hate to say.
