Re: Boosting STFM: 16MHz bus, 64MHz Shifter

awesome, I see that fonts are 8x8 instead of 8x16 and gadgets are a bit too wide. Maybe something else should be patched in that patched Overscan1.6, Most certainly :) I've only edited lines and byte widths for these tests. I propose supporting all the doubleST video modes (including this sw-only a...

Re: Boosting STFM: 16MHz bus, 64MHz Shifter

(I never got the 48MHz thing to work, MMU-Shifter doesn't seem to like to run on non-4 word aligned modes) However, you probably have read about Czietz' software discovery where he figured out how to run the GLUE and Shifter in separate videomodes. For example, GLUE believing it's in high res (71Hz,...

Speculate shifter resolutions based on 50mhz bandwidth ;)
Yeah I wasn't sure whether to plan for FPGA-MMU as well :)

Re: Really crazy idea ...

With the reSTFM (sorry exxos, don't recall your name for it) we should be able to do both the doubleST* video modes (640x200x16, 1280x200x4, 1280x200x2) but also thanks to czietz' amazing sw-solution discovery also 320x400x16 and 640x400x4. And if we include Smonson's Shifter-FPGA one more very attr...

Does anything actually use the -12V in the ST ?

I searched for a 12V point in my ST for a while, and the only one i found was on the monitor port,
i connected a cooling fan to it.
Serial port, right?

Re: Unicorn ACSI-USB adapter speed ?

I'm not home for the next two weeks, but will measure when I'm back home. I really like my Unicorns, but they're slow. HD-streaming demos don't work etc.

Re: STFM 4MB SIMM ADAPTER KIT INSTALL BLOG

I'm halfway through and have managed to get 8 out so far - hopefully they all still work :) Because my motherboard is a 520 st, I need to put resistors in r71-73. I understand they're supposed to be 68r, but I only have 47 and 120. Will either of those do the job or shall I order myself a few 68s. ...

Re: STFM 4MB SIMM ADAPTER KIT INSTALL BLOG

I used a hot air station, boiled the solder topside, pulled the chips out one by one with a plier - and all chips still worked afterwards and have been used for subsequent 520ST piggyback RAM upgrades. But yes, you "shouldn't" hot air through-hole etc, but in my experience the ST motherboards can ha...

Re: 1.44 Floppy mod kit new revision

I must confess that with Goteks so easily available, and the great firmware that can be used with them (FlashFloppy, HxC), I find it a little strange that people want to go to a 1.44Mb real floppy drive, but everyone has their own preferences and it's good that you have options for people who want ...
