Thank you!

Hello, Can somebody share schematic diagram for 32Mbit Multirom EPROM 2in1 ? I tried to use 74HC74 flip-flop chip for 2 games x 16Mbit with this diagram but it doesn't work. :cry: I use method of combine two files with command line "copy /b" Thank for help. https://i3.imageban.ru/out/2021/...

How program 10F322 with TL866 ?
When i type 10F322 in search Device,
Minipro dont find that part.

Any idea ?

I tried, 74HC161 works fine for flip-flop function.
Thanks

Hi everyone, Here is my final work of SNES Repro 27C160 / M27C322 Lo/Hirom pcb design for 16Mbit and 32Mbit! Thanks for community and everyone who helps here. :wink: https://i1.imageban.ru/out/2021/01/18/be28f7298803acc1d4f89183d28e09db.jpg https://i5.imageban.ru/thumbs/2021.01.18/1ceb1382d7570efb74...

Thanks for answer, I use DIP16 "LS" chip to do Flip-Flop multirom counter. What do you think, will it works with "HC" ? When I order my pcb I can not find 74LS161 SOIC16 chip with assembled service. Only HC is available. It really depends on what you're doing, specifically what ...

No, they dont have "HCT"

Hi, I'am looking for to remplace my 4bit counter chip SN74 LS 161 (dip one) by SOIC one. Can someone help me to find equivalent, please. Exactly with " LS " I can not find it with assembly PCB service. But 74 HC 161D, yes. Will it be exactly the same? Thank you The LS and HC tell the tecn...

Hi,

Exactly with "LS" I can not find it with assembly PCB service.
But 74HC161D, yes.

Will it be exactly the same?

Thank you

Hi everyone, Here is my final work of my pcb design ! SNES Repro 27C040 / M27C801 Lo/Hirom - Multirom support (2in1 or 4in4) https://i6.imageban.ru/out/2020/10/29/0ea01cbe57bc2e6443985e44dbada44f.jpg https://i2.imageban.ru/out/2020/10/29/cb48d43c775a82bd01f87b249a8464d6.jpg https://i4.imageban.ru/ou...

Here is my last version of pcb. https://i6.imageban.ru/out/2020/10/29/0ea01cbe57bc2e6443985e44dbada44f.jpg http://rover.ebay.com/rover/1/709-53476-19255-0/1?icep_ff3=2&pub=5575378759&campid=5338273189&customid=&icep_item=274405099559&ipn=psmain&icep_vectorid=229480&kwid=9...

After what I found on the net that other people do.
I Will test this schema and tell you if it will works for M27C801 2in1 HiRom/LoROM, without making SWAP BIN:

Hello to everyone,

Do you know If there is some software to create easy SNES Multirom menu ?

If some one are need this informations :
M27C801 pin 24 (/OE) -----> Cartridge connector pin 23 (/RD)
Or
M27C801 pin 24 (/OE) -----> Cartridge connector pin 49 (/OE)
Two version will works.
