The only major differences between the different SA1 boards are the amount of RAM provided. The PCB code tells you what any given board provides : 1L3B means 1 ROM L SA-1 3 - battery-backed 8KiB SRAM (also seen: 0=none, 5=32KiB) B - battery (also seen: N=no) fifth digit: amount of not-battery-backe...

Hey all, I'm looking to build a dev board for trying out various SA1 ROM hacks, and I was wondering if there were any boards that wouldn't work? I've looked at all of the different PCB types, and they all seem to have slightly different variations on each other. I just want to pick up the cheapest S...

Looks like Analogue is starting up production for their own take on an SNES FPGA clone with the Super NT. I'm curious how it will fare in comparison to the VeriSNES. Do you happen to have any ideas? They don't claim 100% compatibility, but they also don't clarify which games aren't compatible either...

I searched for TL866 adapter for 27 series eeprom. Check this deutsch forum, goole translate can help. https://circuit-board.de/forum/index.php/Thread/16753-42-Pin-Eprom-mit-40-Pin-Programmer-beschreiben/ Finaly I bought similar pcb, from one pal from Ukraine. It works, 27c160, 27c322 are programme...

Does reading the datasheet for the MX29F1615 make sense, or does it confuse? Basically, programming one seems to come down to having something (like an arduino or any other microcontroller) that can drive specific values onto the EEPROM's address and data lines, and then drive Vpp to 10V. Programmi...

You're almost certainly SOL. The TL866 does support the uselessly smaller pin-compatible 40-pin 16-bit DIP ICs (27C240, 27C4002, 27C4096), but those max out at 512 KiB/256 KiW. And that form factor only ever came in UVEPROM, so you won't be able to erase the MX29F1615 regardless. For just programmi...

Hey all, I have a MiniPro TL866A programmer that I purchased from AliExpress here . I'm looking to program some SNES chips, specifically using MX29F1615 chips which are the flash version of 27c160. I've purchased them from this page . What I discovered though is that my programmer only has 40-pins, ...
