Re: SCSI2SD for TT help configuring!

For a SCSI bus to work reliably, it must be properly terminated both ends. Anything else *might* work (more or less by chance), but doesn't necessarily need to.

Re: SHIFTER reimplementation on FPGA

The manual's another thing that doesn't work for me in Quartus 13, but I read up on glitch-free clock multiplexers earlier and realised that it's not a simple problem to fix. I assume you mean that the help system doesn't work, because the manual is a plain PDF file. Yes, the help is picky and migh...

Re: SHIFTER reimplementation on FPGA

Well, I've spent an hour and a half looking at the simulation function in Quartus, and it seems that version 13 (the last version that supports the Cyclone-II) is buggy and can't run ModelSim. A bit of a dead end unfortunately. Do you try Quartus/Modelsim on Linux or on Windows? Quartus 13.1/13.0 /...

Re: ModelSim closes at start

Anyway I'm installing a ubuntu machine to have a try on it. That will require some tweaking as well - ModelSim/Quartus 13.1 will not run on current 64bit Ubuntu. This hint worked for me (with current 18.04 LTS as well): http://mattaw.blogspot.com/2014/05/making-modelsim-altera-starter-edition.html

Re: Atari TT030 and system V

My first experiences with linux was actually on a TT. Well, quite old version, something like 1.2 or so, and at that time 16 MB were more than enough. I had Debian 2.0 (1995, 2.0.34 kernel) running on my TT when they were still supporting m68k officially (actually, 2.0/hamm was the first version th...

Re: Atari TT030 and system V

On Linux, exactly measuring a single process' memory usage is anything but simple. ps ax gives misleading information in that it reports reserved (mapped) pages for a process and not really *used* memory; if a process uses shared libraries and/or multiple threads (both applies to Firefox), shared pa...

Probably you'll be rather disappointed. The X-Windows protocol was fine when the average Motif application consisted of a handful of buttons and pulldowns. Modern applications (like e.g. Firefox) are worlds apart and way off the capabilities of your TT to be usable (even slow on modern machines and ...

Yes, I think it has an ET4000 driver (at least in older versions). But NetBSD has a completely different driver model than SysV, so no drop-in replacement possible, unfortunately.

I'm down for a complete TT replica, but it would have to be an exact replica with same CPU and everything else. I want to run Atari Unix on it.

Interesting. Decades ago, Control Data was my very first employer.

Never seen the Plato system live, however. But if I remember correctly, the exhaustive NOS/VE (the follow-up OS to NOS) help system (which I had to use a lot) was a direct descendant of it.
