I can buildup up and test the supersoft boards if you like

It would be great at some point to get dumps of the SuperPET roms…. I had to make up a 50hz E rom and curious how the settings compare with the official ones assuming MMF9000 is setup for 50hz.. you know if it isn’t as in Superpet mode the screen…

Die Kühlkörper waren ein Volltreffer! Allerdings bin ich gespannt, ob die Wärme da auch wirklich sauber abgeführt wird… sie sind federleicht- viel leichter, als der vorherige Kühlkörper, welcher auch schon verdammt heiß geworden ist.

Egal: Der Look kommt…

Actually built a version of PETSD+ (using last posted code version) that has the OLED reset fix in place (after research on the internet) … not done a lot of testing but the device boots fine and resets ok.

Very nice … not sure I have the COBOL user guide….. I did sell my first SP9000 to make space - it had those keyboard stickers…. Haven’t found them since. My current SP9000’s do not have them.

Ah ok… power cycling works fine so will put in an on/off rocker switch also

Ich nehme den Rechner morgen mal zu jobi23 mit.
Wenn wir dort nix finden, besteht noch die Möglichkeit, auf der CC zu forschen- wenn jemand von euch Lust dazu hat?
Auch könnte man mal ein kleines Grill-Event mit Fehlersuche bei mir machen.

Hi Vossi,

Do you find the reset switch working correctly every time with the OLED screen …. Sometimes I get screen corruption which can only be sorted by powering off ? The LCD screen works fine.

My roms are soldered in other than the f-rom which has been tweaked for 50hz. Not sure it’s that… when I was messing around with the 2 board version i had to swap the ram from the ITT to TMS4116-15 to get any sort of operation out…

Yes you see that block at the top … it’s also noted somewhere in the user text on one of the floppies

Been on for an hour with occasional dir commands executed …. JP1 closed.

Mine has been on for 45 minutes no problem

Ok .. is JP1 closed also as think it is on mine … will check. Is switched on right now and doing occasional dir’s to see if still working but mainly idle.

Quick question, the MMU board from retro innovations has a configuration link … JP2 …. one configuration for the 2 board version and another for the single board version. I haven’t studied the difference in the circuit but when I look at the…

I passed on most of the os/9 images to Bo having collected them from various people over time and also built some application images (c compiler, forth) up by taking files from os/9 images for the dragon 64.

One thought, have you monitored the 5v voltage…

Just give me a few days as work is taking my time right now ….

Sure, happy to test … I use zoom floppy to create the disks from the .d80 image

Wasn’t going to be that easy was it ….. I re-read some of the superpet gazette articles and they reported no known issues with the single board version. Will power up my SP and check out the IC’s used ..

Puuuh, not sure if I checked that yesterday with the "new" mostek 4164's. test.main + test.banks ran perfectly fine.
With TI DRAMs it crashed/froze.

Will check it that evening/night!
