Re: NetBSD 7.1 on the Atari TT

How TT specific is all this?

I'm very interested in getting a modern unix onto my Falcon CT60e and the existing Debian m68k seems old and lacking from active maintaining.

Re: STFM C070789 6 CHIP TO 2 CHIP CONVERSION

Just to make it even more clear - if there's no chip at U68 you need to install a 74LS11 there - it's what combines the chip selects that were for six chips down to two. (I've seen more than one person buy a 2 chip replacement only to find out they have to order the 74LS11 as well once they've alrea...

Re: WD1772-0202 - overheats at 16MHz

I would assume the MSTE stays in 1.44 mode (16mhz) until you access a 720K floppy again.. I guess you could format a 1.44, swap to a 720k read the disk.. leave it for a hour.. then try a 1.44 again.. would assume it would work ok in that test. Yeah I had the same thinking, so I did, but it didn't :...

Re: WD1772-0202 - overheats at 16MHz

Oh well, busting myths ("all -0202 work!") is also creating new knowledge .. ;) Indeed. 0202 was later and more likely to work, in theory. But I've tested 100s over the years and its just pot luck. I class the vl as old tech, seen them in old BBC machines. Some of those work, and some 0202 don't. Y...

Re: WD1772-0202 - overheats at 16MHz

I don't know how the mste works with speed switching. Might be worth scoping it out ? AFAIK TOS sets (that's what the GAL does) the speed of the 1772 depending on whether it's able to access valid sector contents or not. Whether it leaves the chip in 16MHz until next (failed) sector read I don't kn...

WD1772-0202 - overheats at 16MHz

"Back then everyone knew that the WD1772-0202 could do 16MHz, thus 1.44MB" Yeah I've said that myself many times. So when I bought my Mega STE (TOS 2.05, 720KB drive, -001 PAL) and saw it had the -0202 I immediately set out to upgrade it with a proper GAL and Epson 340 drive. And verified it indeed...

Re: Lost the content of an hdd, atari compilation gone

I value time above anything else nowadays. So, since I'm not the only one in the family (but also for me), our setup is that I run a home server with RAIDed disks. That server also runs the Seafile personal self-hosted cloud service (think Owncloud/Nextcloud but actually fast). All mobiles and compu...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS

You can't halve E-clock from the CPU to ACIA.. Believe me I went to great length to investigate all that.. http://www.exxoshost.co.uk/atari/last/16mhz/index2.htm maybe around 10th jan there... This is the main problem I have at the moment and why I am moving to the SEC CPU as you can actually contr...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS

I guess ACIA maxed out here (about 1.3Mhz) . I have the "B" versions *somewhere* so will change them soon and re-try... But really I maxed out what I can do with this test board... That's something I thought about regarding the "Stefan 16MHz mod" (doubleST is what I call it). The ACIAs run at 1.6MH...

Re: Silent 40x40 fan

:bravo: Can you "feel" the air flow between fans ? Normally quieter fans are shifting less airflow. But of course it does depend on bearings etc used. Well a lot of the Noctua magic is supposed to be about their bearings and total airflow layout etc - but yes - at least down-volting it as I did the...
