Re: Beginning of very long journey

I think ISP1161 is actually the same silicon as ISP1160, only that the USB device controller part is enabled as well -- but you don't need to use it, of course. So I'd expect ISP1161 to work right out of the box. I (or we as the Lightning VME team) don't have any experience with the ISP1161, though....

Re: Beginning of very long journey

USB: Phillips ISP1160 In the Lightning VME we're using this one as well, basically for the same reason: drivers. Just be warned that you'll encounter some supply-chain issues with the ISP1160. It's long discontinued, hence it is only available at more or less dubious obsolete parts dealers. During ...

Re: STe - Bad DMA Chip

The "bad" DMA only has problems with certain hardware. E.g. original Atari disks almost never gave problems. I guess that's why this bug slipped through the engineers' fingers in the first place. Yes, but the Gigafile (along with the Ultrasatan) is known to be problematic in some STEs acc...

But you did all tests with the same HC CPU? Maybe it's the CPU. Not the fact that it's CMOS, but this one CPU. As for diagnosing this further: If I understood it correctly, Closure crashes. Any chance you could retry this with EmuTOS so that troed would get a more detailed crash dump? Or -- assuming...

That's quite uncommon seeing that Shifter wakeup issue on STE actually. My 1040STE also had these black bars (mind you, still with the original NMOS CPU, I'll swap to CMOS later). It took me several power cycles to get to the wakestate in which Closure displays correctly. Maybe my STE is "spec...

Re: STe - Bad DMA Chip

As for your STE, I suppose you already checked yourself, but just in case: look closely at the contacts of the CPU socket. I once managed to bend a contact while swapping CPUs causing the STE to stop working as well. Fortunately that was fixable. And just nitpicking: the original 68000 is not TTL (w...

Although it's maybe not the source of the problem, I noticed something else with your code. void screen_char_draw(padPt* Coord, unsigned char* ch, unsigned char count, bool queue) ... gets passed a pointer to the character(s) to be drawn and the count.

Re: Help identify the mods on this MEGA

DMA capable. No additional circuit (followed by something illegible, perhaps ist= is/was ) tested with additional circuit on 17-06-98 I read "keine Zusatzschaltung erf.", where "erf." probably means "erforderlich" = required. Hence: No additional circuit required.
