Forgottenmyname - Progress - Part 2
Re: Forgottenmyname - Progress - Part 2
I've just removed the 4 chips and am putting sockets in but will check those after
If it ain't broke, test it to Destruction.

You sir, are a genius as usual
A blob of hot snot had given me a dry join on Wdat

Re: Forgottenmyname - Progress - Part 2
No, got 1 bit of ram with a fault. will track it down with the scope

Re: Forgottenmyname - Progress - Part 2
Fixed a couple more dodgy connections but still got 1 bit failing, so need to track that down with the meter / scope over the weekend but so far it's looking promising for my second Alpha board.

Re: Forgottenmyname - Progress - Part 2
If you know which bit then you can probably trace it to the ram and buffers.

Re: Forgottenmyname - Progress - Part 2
Yeah it's just associating that bit with the falcon ram board that I've not worked out as yet.
I did notice that pin 60 one of the Mad lines IIRC on the MMU has a very poor signal, goes to R64 and then to the Ram but it's got that with or without the Ram board attached.
Learning lots doing this.

Re: Forgottenmyname - Progress - Part 2
so this is the latest mem failure using the diag cart as I prefer the feedback it gives for memory diagnosis.
so I know that the right 16 zeros means D0-D15 from fixing my 32 chip STFMs, can someone verify for me what the left mean please.
I know it's byte 1, is this indicating A1 has a failure? or Mdata1? I did have a few loose connections which I sorted out, for instance pin 60 on the MMU was bad in the socket and wasn't making contact with the ram but thats now fixed.

I thought the left side is the address lines. I could be mistaken though.PhilC wrote: ↑Sat Jun 29, 2019 4:56 pm so this is the latest mem failure using the diag cart as I prefer the feedback it gives for memory diagnosis.

Re: Forgottenmyname - Progress - Part 2
They both look 16 bit, but maybe diagrom assumes 030 CPU and does 32bit access... but even that wouldn't';t make sense as the same bit on the left bank would also be stuck...
Maybe ping TF and ask him what it means...
