Hi follks, as stated on the page 4-4 of the Vortex Service Manual, i've changed the default 64K x4 DRAMs ( U15,U18,U20,U21) with 256k x4 DRAMs,with the addition of U10.
I've done this in the hope to expand the delay capabilities of my unit, but after mounting the new 256k DRAMs never changed,at least i'm not able to listen to some changes into the delays,they don't seem to be expanded. I made all the diagnostic required too and every things works fine.
what could be the reason? does somebody has experienced with this matter?does it could depends on the fact that my Cpu processor is the first version?
let me know,
