Had a fiddle with Ultrasatan. If I keep it turned off until I get to desktop then launched the driver, it seems to work fine. However, if it is turned on and I power on the STE, it seems the lock-up just after the Atari logo. There is some flashes on Ultrasatan but nothing else happens at all. It boots fine in EMUTOS, so not sure this is a hardware issue.. not sure..

EDIT:
Ah its got ICD driver on the drive. So I need to get rid of that next.. (I just booted with the stock machine 68000).

I'm pretty sure the buffers are not supposed to be 74VHC245

Haha! Well done!

So they stiffed you at the assembly house?

@stephen_usher your DIR pin comment was closer to the mark than it should have been!

Well done @exxos - great to have that option for the STE (and so probably the easiest install for the accelerator on any ST as a result)!

So glad you persevered!! Good work!!!

Great

Thanks guys

Got a odd crash issue to figure out next. I ran GB6 for a couple hours and was fine though.. I am hoping it's something simple like I'm using the plastic CPU at 50mhz.. it also seems a bit slower than the ST536 which is odd.

Did a quick test as to why integer division is only showing 1660% when it should be 1728%

Currently I don't have anything in the auto folder..

So I load GB6 and with the blitter DISABLED I get 1728%.
Then with the blitter ENABLED I get 1660%.
So I DISABLE the blitter and it still shows 1660%

As I side quest, I wondered what would happen if I put BLT_FIX to run from STram vs TTram.. Was a little bit of a difference...
