V1 STE booster - anyone with integrated blitter tried it ?

Post by exxos »

Thanks. Board seems to be stable at the moment, I think if the 32 MHz wire is rooted anywhere near the MMU it causes the machine to go nuts. I have already documented this behaviour with parity Simms, seems the MMU is ultrasensitive somehow.

Next time I have a separate blitter model connected up with the booster, I will experiment and see that MMU is still a sensitive as the integrated one .

Yes, I routed the clock line below the memory modules, with quite some space between it and the combo chip. But I can recall when I first tried it with me self made adaptor socket, that the hole setup was incredibly instable and in that the position of the clock line had a lot of impact. Mainly distance between RAM and combo chip were factors. It only occasionally worked at all when having the clock line high in the air, or routed above the RAM modules.

Yes the clock line bit of a nightmare.. The STE booster does seem to work fine with a separate clock. I will do some more testing with this soon. Though I am thinking it will be easier to have a oscillator on the board itself. 35MHz or thereabouts should be possible. Mission for you ;)

Kewl, new toys :) Good thing, I left the booster (un-)pluggable ;)

Well you only need a 35MHz 5V oscillator ;) it has been tried before..

This alone proves to be difficult... All my usual sources come up empty for 35Mhz-Oscillators. Only Mouser has them listed, but not available.

36MHz like this one https://www.reichelt.de/Oscillators/OSZ ... FFSET=100& would be no problem...
