Re: exxos build
Finally tested the PLCC MFP!
I don't know if anyone else has tried that or not, I cannot find the "tested list" @Icky ?

Re: exxos build
@exxos got the socket but never got round to getting the chip.
If it ain't broke, test it to Destruction.

Right.. lets see if I can updated it without ballsing it up..Icky wrote: ↑Sun May 03, 2020 9:44 pm Not tested yet @exxos and list is here https://www.exxosforum.co.uk/forum/viewt ... =78&t=2457

Re: exxos build
Been puzzling why the TF536 kept resetting on my H4 so did some quick poking out just..
For some odd reason its really sensitive to the ST's DTACK. It only works when I touch DTACK or have the scope probe on it signal looks otherwise fine on the scope. So not sure what the issue is there. Could be some slight timing issue somewhere @terriblefire ?

Re: exxos build
Possibly. The way it works is that it lets ST DTACK become DSACK1 after a resync period has passed.. By that time the 030 is in 7Mhz mode..exxos wrote: ↑Wed Jul 08, 2020 11:22 am Been puzzling why the TF536 kept resetting on my H4 so did some quick poking out just..

Worked really well on my H4. :/

Re: exxos build
I don't know if the xilinx stuff can have schmitt inputs or not, if it has (and not already) turn it on for the DTACK signal ? I mean scope probe is like what, 3pf on x10 or something. So might just be picking up noise.. Or possible doesn't like the slow rising edges of DTACK ?terriblefire wrote: ↑Wed Jul 08, 2020 11:33 am Possibly.

EDIT:
I tried adding 10K pullup on it (already has 2.2K on the H4) but didn't help.

Re: exxos build
There isnt a Schmitt trigger but i can get rid of the noise by sampling it with the 100Mhz clock... will just delay dtack by 10ns...exxos wrote: ↑Wed Jul 08, 2020 11:52 amI don't know if the xilinx stuff can have schmitt inputs or not, if it has (and not already) turn it on for the DTACK signal ?

I can try that if you have the means to reprogram it?
