Re: STinG driver (TCP/IP networking for TOS) for USB2LAN adapters

ow...That's about just about half the speed of NetUSBee... may be the TT CPU needs boasting ( is that the project next on the list???). Just to clarify for other readers: with the NetUSBee you're using the network part, USB is not involved at all. Considering that with the USB2LAN data on the other...

What sort of network transfer speed are we getting here ?


Greatly depends on the USB host adapter that you're using. With the Lightning VME I measured something like 140 kByte/s, iirc.

Re: Beginning of very long journey

OK. So I was at my old computer today. There is one further set of Gerber files claiming to be from the Falcon. However, I was never able to display them properly, so I assumed they were corrupted. Until now! Turns out, with the proper tools and settings you can very well display those files. I used...

Re: New FTP client available

I don't think that this is the issue. As said, i don't even get the welcome message (type "HELP" blablub), which should be printed even before the presence of a driver is checked. Could it be that text output (more specifically Bconout, as used by PFTP) is buffered, so that even though th...

Re: Beginning of very long journey

Please don't forget, the available gerbers are not complete, most likely missing major VCC and GND planes Iirc, the GND and VCC planes are there, it's just that no components are connected to them as mpattonm already wrote. One would expect to see something like thermal traps on those planes around...

Thank you, Roger! We Lightning VME developers use PFTP to benchmark the speed of the STinG network driver simply because it is the fastest FTP program.

Re: STe - Bad DMA Chip

Also for the record: my STE has the supposedly "bad" DMA IC and an NMOS CPU as well and still works fine with ACSI devices such as the Gigafile. This shows that even that combination is not guaranteed to fail as ijor already mentioned. (I really had hoped it would, because then I could hav...

Re: STinG driver (TCP/IP networking for TOS) for USB2LAN adapters

eth.udd and asix.xif are included in the FreeMinT binary snapshots available at https://freemint.github.io/. I don't know, though, why they package the asix.xif driver into the "megaste" folder of all places. Maybe this can be discussed on FreeMinT's Github bug tracker.

MegaSTE power LED: Mixup in the PCB layout?

Hello, one cosmetic thing that annoys me with my MegaSTE is the extremely dim power LED. At first I assumed this was simply due to old age. But then I measured the current: only about 2 - 3 mA, which is much less than one can expect according to the schematic: http://gossuin.be/images/schemasatari/M...

Re: The SECRET VIDEO MODE in an ST: 400 lines in COLOR (and with 72 Hz)!

You have a mono/color selectable VGA switch right? Enter the mode and then flick the switch while connected to the same monitor as you use for regular ST resolutions. Actually, I have neither a switchable VGA adapter nor a VGA monitor capable of 15 kHz timing, and that's precisely the problem. I co...

... and:
160 x 400 (16 colors out of 512),
1280 x 200 (mono, untested because I don't have a suitable monitor),

although for these two the aspect ratio will surely limit their usability.

Re: The SECRET VIDEO MODE in an ST: 400 lines in COLOR (and with 72 Hz)!

OK, I figured out what happens with the STE. There, in mono mode, the GSTMCU will not generate a BLANK(ing) signal, since that is not needed in monochrome mode anyway. Hence, if we only switch the Shifter to color, /BLANK will be constantly asserted and thus the RGB outputs are blanked. This is why ...

The bad news is that it doesn't work on STe (two tested). The output is black. Even if the mainloop goes haywire and add.w $0123,$ffff8240.w in a loop there is nothing on screen. The OSSC reports 35.8 kHz / 71.47 Hz refresh rates. Yes, this is what I observe on my STE as well. Coming from mono mode...

This is fantastic. I've spent a lot of hours trying to achieve something like this. How are you running GLUE in one mode (high) and Shifter in another (color)? I can indeed have Glue and Shifter in permanent disagreement about what the video mode is. The key to this is that Shifter doesn't have a a...

The SECRET VIDEO MODE in an ST: 400 lines in COLOR (and with 72 Hz)!

I guess I found something interesting: You can switch an ST to a "hidden" video mode where you get 400 lines in color instead of the usual 200 lines. Differing from previous attempts of achieving new resolutions, this neither needs hardware modifications, nor is there any sort of interleav...
