8meg.lha RAM expansion project

[Radfoo]

Hey,

Has anyone every tried making an 8mb expansion for the A500?  I have found one called 8meg.lha on aminet.  Anyone know of any other guides or advice on making one?

Would make it for the A500 first but has anyone ever tried adapting this for the A1200.  I notice due to the 020 '_UDS and _LDS' are missing, did google some info on this but cant find it now, doh!

Thanks

**Edit**
Found the 020 info
Note that unlike the 68000, the 68020 has a pin labelled A0; this is because instead of having two data strobes UDS* and LDS*, the 68020 has only one data strobe pin.

Just for fun really and hopefully learn something along the way :-)

I'd seen the A608 before but not realised I could get the schematics, will be looking at those in a mo :-) .  Thanks for the 020 link, i'll be following that one.
