Do you use any isolation material between the adapter and Atari board?
Something like some card has to be used to stop the PLCC socket from shorting on the motherboard.

I mention it on my site http://www.exxoshost.co.uk/atari/last/blitter/index.htm and on the store link.

Re: Change wakestate at every reset

Heh, thanks - it's nowhere near the stuff you're doing, but it's at least a baby step for someone like me who's never done any micro electronics ;) I installed Eagle yesterday ... At least your doing something constructive, matters not big or small project, its progress into understanding the world...

Re: no-software internal RTC

It's slightly annoying that I did have a picture of a battery back up mod for the ST keyboard, but I don't seem to be able to find it right now :( Peters site has the diagram of it. I have seen it done on keyboards I have had in the past, but mostly was just leaked batteries so got binned. I think ...

Re: no-software internal RTC

Does the rp5c15 itself support dates over 2000 ? The datasheet doesn't seem to say. Of course like you say, software is patched as work-around for this. In my future projects I plan to use same RTC kit as I produce for Falcon RTC replacement. Of course need some basic software to use it on ST.. Falc...

Re: no-software internal RTC

Sounds like a great idea. Would assume all the info would be in the data sheet for the keyboard ic ?

Re: ST RTC EXTERNAL BETA - WIP

That's why I was thinking rather about a pass-through device connected between keyboard and motherboard, that would set the RTC in the keyboard from the modern DS-1307 battery backed-up RTC on this device on power up, and after that be completely transparent or would intercept queries to the origin...

Re: ST RTC EXTERNAL BETA - WIP

Wiring to the ROM port is easy, but how are you going to get the software to run from the ROMs ? You cant just copy files to the eproms and have them work. It would take some work to adapt the software to cartridge, I can't see anyone putting the time into that when the program is small enough to ru...
