Really P'd off
Really, REALLY p'd off. Ordered a Super Gold Card, received it and it doesn't work.
Was supposed to be in good condition. Now it'll have to go back
Mutter, mutter mutter

You woke me for THAT!!!
Re: Really P'd off
All in all over $400.
The seller has refunded and I get to keep the dead unit.
Now for some searching for circuit diagrams and such.

mk79,
You do know that Dave is producing a device with similar capabilities to the SGC. Look in the General QL Chat. Proposed cost around £70.

Re: Really P'd off
It's *just* a memory expansion that contains a CPU to get the two extra address lines. It runs that CPU at stock speed of 7.5MHz and 8-bits data bus, so it in no way compares to an SGC.
It's just a big, cheap memory expansion that does some clever things.
Just saying...

Whopper,
If you do find a circuit diagram for the SGC, I would be interested to have a look - I am keen to know how the 2 74hct244 chips are connected...

Hi,
If I thought I could get $400 ???? Whsts thst in real money... I would fix the SGCs I have.
I doubt there is a circuit diagram. But the SGC is only 4 layer board so should be straight forward draw a schamatic. But it still maybe copyright.

Derek,
That included postage and import duties. They took a huge chunk of cash.

Two HCT244 and one HCT367 is for buffering A0 - A19, DSL and R/WL lines from SGC to QL.Pr0f wrote:Whopper,
