My board arrived today, hope to test it out tomorrow. :cheer: :cheer:
Great @PhilC. I just posted a guide on how to install here - viewtopic.php?f=78&t=2466

You can replace the ROM on the H4 with the 104/206 one you have on your IDE DEV board to take advantage of TOS 206.

Will be interesting to see how yours behaves compared to mine on the H4.

@Icky yes thanks for posting that. I'll have a go a bit later on. Hopefully fix the SMT board too whilst I'm at it.

Working good on my STFM...... I think there is some irony in this somewhere with the not working on the H4 :lol: :roll:

Left it on all night with ultrasatan plugged in. GB6 outputs the lopo count and time into a text file every loop (what a awesome feature! :lol: ) So US gets tested the entire time writing to it...

So its basically been turned on for 24H pretty much now.

I always wished it would put the current loop number up in the menubar, so if you're looking at live output, you don't have to wait for the end of a loop to know how far it's gotten.

I have had the same thought in the past actually :) Though its why the screen flashes red when it displays the loop count to get my attention ;)

@PhilC - try it with a 32MHz osc and see what happens :)

Yeah just remembered what you said in the email. It boots with the 32mhz oscillator.

Still bombs with a floppy in at boot though, or when I try to access a disk at the desktop.

It seems to get stuck at busy bee for longer than it should when loading the desktop

Just re read @Icky email from the other day and his H4 works at 32mhz and boots but mine crashes on floppy access.

U had a bad DMA problem exactly like this on one of my Megas, so I think its time to swap a few parts out and see if that improves matters.

Will report back later.
