In Topic: MiniWriter 3 cart (with novel, integrated parallel interface)

My guess is the printer port is memory-mapped in the cartridge space, something simple.  DBT used CRU bank switching in its cartridges but, with the exception of later models, the circuitry does not look complex enough for that.


Do you imagine that outputting to the printer was writing to that address space and that data was the datastream for the printer? Or do you think somehow reading a certain section of data was what caused the data stream -- where a read access is handled as a signal to output data. Doesn't looks complex enough for me. I guess I'm just coming from the notion that you can't write to the cartridge port. But then, I guess there's MiniMemory, though, right?




In Topic: computer users groups: then and now....?

I belonged to P.A.C.E., the Peninsula Atari Computer Enthusiasts covering the Virginia peninsula (south east Virginia) in 1986-88 or so. One of the places we would meet at night was this Lutheran school in Hampton, VA. I just got in contact with someone there who was able to provide me with photos of the Atari 8-bit lab we would do our meetings in from that period. I am going to write it up on my blog, soon.


I talk a little about that group and others in my blog post from a few years ago.

_The Doctor_

Umm, I am new to the A8 scene and as such hadnt seen years of posts about clipping the caps. Seeemd the machine had a serious issue with the SIO2SD and I decided to take Lotharek as an authority. I tried several max speed settings with no luck. Are you suggesting clipping the caps was a bad move somehow? Not sure where youre coming from. ?

I clipped out the two caps -- works perfectly now. Lotharek knows his stuff!
