REV 3 - REV 5 - The beginning (ST536)

Yep.. Floppy doesn't work else..

That's probably the underlying symptom. We know MAPROM works for other 536s.

In unrelated news, my "stuck D11" line looks very much like it might actually be a mistake in my maths and I've probably just subjected my board to a vast array of extra rework for no reason. :oops:

I have never gotten it to work, not even with a original board.

The issues are known in fact https://www.exxosforum.co.uk/forum/viewt ... =10#p44079

Crikey. I'd missed that and not experienced it.

How about giving ROMSPEED and I Cache off a go?

I think a lot of the problem is TOS 2.06

Ah thanks. I have just been trying to get that working from the previous thread, it just locks up after reset don't know why, but will try that program you posted instead..

@Badwolf Sadly the program does not work, complained it is not a Falcon :(

EDIT:
will see if I can hack it..

EDIT2:

Well that went well :roll:

Oh! Sorry. I didn't realise it was machine locked.

It seems the gremlins have been in overnight as well :roll: Even though is working perfectly well for hours yesterday after fixing the reset line, a lot of the time will not boot without physically pressing the reset switch, and MAPROM basically intermittently locks up after loading now :roll:

EDIT:

Another odd fingers well, after loading MAPROM, if I yank out the ROM CE wire as it quits back to desktop, it crashes, if ROM was truly running from ram this should not really happen...

Looks like it could be changed but I cannot get it to compile anyway :(

Code: Select all

.nomag:	cmp.l #"_MCH",d0
	bne .nomch
	cmp.l #$00020000,d1	;TT or newer?
	bcs error	;no-

Finally got TTRAMTOS to work...
