A4000 112MB Memory hack
Hi
Here's Meutoxo's improved version of Meutoxo's memory hack :-)
You can:
a) use 1x 64MB simm and use 64MB with fastramsey (requires the 64MB jed)
b) use 2x 64MB simm and use 112MB without fastramsey
c) Use a 128MB simm to use 112MB
All 64/112MB of memory are autoconfig.
I've done the hack successfully in two different A4000D (desktop and micronik) and also in my A4000T (let me know if it works for you as we only tested it on my own A4kT) so I will provide support here, don't bug Meutoxo as he's very busy.
I have not attached the doc file and just the PDF as it made the archive too big.
If you do any change to the pcb or jed files please share here.
BTW, I've noticed that the new A4000+ motherboard seems to lack the empty GAL area, in that case you will need the PCB on top of ramsey just like A4000T owners.
Enjoy
