Re: MCGenjin MultiMapper

I've never soldered a PLCC chip. Is it hard? The smallest package I soldered was the SOIC version of the Atmel 16Mb dataflash. PLCC is not so bad. It's a little more annoying than say TSOP or SOIC because the pins run up the side. The approach I always used was to tin the legs and contacts, then so...

Re: MCGenjin MultiMapper

I want one! :D By the way, how do you upload rom or backup the fram? If you want a pre-made card, please PM me. But it is not so bad to build it on your own. The ROM must be copied to flash using a chip programmer (which is why the 29F032 is socketed). MCGenjin traps all writes to ROM in order to u...

Re: MCGenjin MultiMapper

Hi all, I have just finished testing the 4MB MCGenjin boards, and have uploaded the gerber files and new POF.

Re: MCGenjin MultiMapper

-If there is some interest, I can do board layout for MCGenjin devcarts that have a FlashROM socket and include some FRAM and SRAM attached to the chipselects, then put the gerber files up after I make sure everything works. Same size as a HuCard, but no nice plastic shell. I use 29F032 expanded to...

Re: MCGenjin MultiMapper

Excellent! Is there any production planed? I have parts for five boards like the one shown on the webpage. They’re configured with one MCGenjin, FM1608 (8KB FRAM), and a socket for one DIP expanded 29F032 (4MB FlashROM). The second MCGenjin chipselect line is free to connect whatever is in your ima...

MCGenjin MultiMapper

Hi, I've started working with the PCE and made a multiregion memory mapper. http://www.penguinet.net/TailChao/Hardware/PCEngineKit/MCGenjin240.png You get up to 8MB of banked ROM and can switch the order of the datalines whenever you like. Two chipselects are also given for whatever use your imagina...
