Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS

On the new 68020 V3 board we use a clock distribution chip, the NB3N551. This might help cleanup the clock and then feed it to your PLL ? Possible, though looking for schmitt inputs to be sure, probably 8 inverters.. 2 on input (act as delay buffer) and 3 on output for inversion + delay.. But I thi...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS

I've gone back to the V2.2 booster for PLL testing.. So far passing though the PLL (driven from 8mhz) results in 16mhz output inverted :roll: So I can the 8MHz though a inverter before the PLL.. but oddly both 16MHz were still out of sync (180deg out of phase). (ignore the ringing) p1.png So I tried...

TOS1.00 vs TOS1.04

Thought it would be interesting to see the speed of TOS 1.00 over TOS 1.04... A little surprising really...

Re: dev-docs mirror & php issues

My mirror was great help to many as the original site kept going offline. Sure it has a new host now but why does this mean my copy should be done away with as that is what you are suggesting. Plus as I already said, I link to a lot of files on my mirror and removing the site will create more work. ...

Wouldn't 'wget -m' be a useful tool instead of PHP (*ick*)?
Maybe... but I still need some method to check the files on the main site vs my mirror to get the "file list" to download... reminds me I need to check the cron job is working :)

Re: Midex+ Schematics and modification

oh wow! I got asked to reverse engineer that a few times, I basically said no as would take a lot of time, and GAL's unlikely to be readable by programmer..

How did you come across all that info ??
