Re: UBE Adaptor and Del 2410

Besides high contrast I'm not sure with what you mean by "blurred"?

Re: Project: HDMI/DVI out for STFM

Hmm, incidentally, Exxos are you running a stock power supply in your test machine? I have a stock PSU, I think Troed has a modern replacement. My 5v level is actually about 4.7v. Dunno if it could be connected but couldn't hurt to rule it out... My 520STM runs off a picoPSU and the 1040STFM off a ...

But so far, It seems like its only failing in stm machines?
520 STM and 1040 STFM (SMT rev) here. It's on my todo to run it on a 1040 STF (red led old model) and a few Mega STs. I'm really sorry for not being able to allocate more time to it atm ...

In any case, it is pretty clear that these ATF chips are working a lot better than the original GAL's I was using.
That in itself is a great finding that hopefully will benefit other hw builders for years to come.

(My 22V10 -10 at home are Lattice, I checked)

Re: Project: HDMI/DVI out for STFM

Also I don't know if it is about Mb revision yet. My Rev.B 520 ST has it in anycase. Do we know if the HDMI boards are ok? Somebody tested those non working boards on a different computer and then it run ok? No, that has not been tested. I'm the one first saw this issue, but on the 520 ST (C070243 ...

Maybe someone can loan Smonson a st with the issue ?
Shipping to Australia is crazy expensive. Also I don't know if it is about Mb revision yet. My Rev.B 520 ST has it in anycase.

Re: Project: HDMI/DVI out for STFM

Thanks Ijor - perfect insight. I should've caught that - I spent quite some time looking into "snooping the bus" on ST and STE (different methods, but reading Shifter palette register values is one).

I can reproduce the problem and I do have a 16 channel LA.

Re: Project: HDMI/DVI out for STFM

I've tested on both an STFM with SMT chips (the doubleST machine, xx589 or what that MB revision is) as well as with a 520ST rev.B. I don't recall if I tested on another STF as well (I think I did but can redo).

Re: STE V1.5 32MHz BOOSTER - STATUS

PD pin configuration is controlled by the design file, and appears as a separate fuse bit in the JEDEC file. When the power-down feature is not specified in the design file, the IN/PD pin will be configured as a regular logic input. Note: Some programmers list the 22V10 JEDEC compatible 22V10C (no ...

Re: STE V1.5 32MHz BOOSTER - STATUS

I can only assume these CPU's are really old, and actually more like 10MHz parts restamped as 20MHz parts or something. Yeah restamping has become a huge issue when sourcing parts. I bought a bunch of ST 27C256 EPROMs a while back and even though all of them were clearly stamped as being M27C256 (S...
