Re: Guide: Fitting the SEC Booster to the H4

Just tried installing the booster on my first H4. If I have a disk in the drive it will fail before ram check on TOS 2.06 but with no disk in the drive it boots to desktop and then bombs when I put a disk in the drive and try to access it.

After discussing with @exxos it seemed to be the Blitter causing the issue. After removing Blitter the floppy and UltraSATAN works together. However am still having issues with Gigafile.

@exxos will do. Will start with a good STFM and once that works, move on to the H4.

Re: Flashy Clock - Yet another DEV board

Looks pretty good, almost professional (no pun intended). So many vias on that. Be interesting to see how difficult it is to build.
