thanks for clearing that up - it accepts 256 k cards.

Gee thanks, and that from someone who should knowbaz99 wrote: And that PCB looks even better than the first one!
Hey Rob -- thanks!Zaichornok wrote: Hey dojoe - looks fantastic.
Yep, SW2 and SW3 together select one out of 16 banks for the 256 model and 8 banks for the 512 model. The banks are A1, A2, A3, A4, B1, B2, ..., D3, D4 for the 256 model. For the 512 model, 1 and 2 are the same bank, as are 3 and 4.Zaichornok wrote: I am not quite clear how to select banks, but obviously it is a combinations of SW2 ans SW3 settings right?
I have no doubt it will be simple to remember once you explain.
That can likely be arranged; afaict you're the first R880 user in here. As for my usual question: Any chance you might supply a photo of an original RAM card sticking in the GC-8, so I can see if there might be any issues with my card? Google image search let me down this one time =(Zaichornok wrote: By the way, I plan to use this for the Roland R880 professional studio reverb. It's a bit of a rare one but still has many dedicated users globally. Was very poular in Germany, and the USA. It uses the 128, 256 and the 512 cards.
Would love to do a beta test with your card and the R880, and happy to pay for the test card up front.
I might just take you up on that some dayZaichornok wrote: One memebr suggested sales of 100 units per year. I would guss at least 5 to 10 times that, or more, if you get the price right, and once word gets out. Just listing the card on eBay would sell hundreds very quickly. The demand for original cards is still there in a very big way. If you want any help /participation in selling your card let me know.
tl;dr: I wouldn't worry too much about it as long as you keep the card either plugged into a synth or inside the static shielding bag I'm shipping it in.Zaichornok wrote: Also, I know you touched on this subject some time back, but how susceptible would the card be to normal handling / static?
