I've just bought a T-48 programmer and your video was very helpful. Thank You So Much!!!

The stm ones aren't too important for what I need but the others would be life savers, I know nothing about this area of expertise but some electronics knowledge and trying to fix a few machines using those chips that I think are the culprits

This setup may help you, but if the ROM chips are damaged or faulty, it would probably be better to write some new ROM chips with the appropriate data and replace the old ones.

G'day Jacob. I got a question, What software did you use to convert ROM files to BIN? I thought I ask as I got the T48 EPROM programmer as I want to program a ROM hack I did to a game cartridge. Any help would be appreciated.

The ROM file should be a raw binary file already. You may just be able to rename it to .bin and use it as-is. There are probably some other tools out there that will let you inspect the file to see if it really is just binary, or if there's some extra header information in the file. A text editor might show you that, especially if it has a binary mode.

Do you know of a site where you can download ROM chip programs?

Dear question, I have an EEPROM memory with a specific number that I could not find in the market. The memory size is 256 KB. Can it be replaced with another? It does not. have to be the same number, but of course the same size, or it must be the same number and the same size. The one is damaged is one time only read memory"TMS27PC256-20NL". The one i will used is UV EPROM"M87C257-20F1". With same size of course i will transfer data with programmer from TM to M8. Can do that because idont have TM eprom. I have M8 eprom.

It depends on the pin configuration. I looked at the datasheet for the old chip (datasheet.octopart.com/TMS27PC256-20NL-Texas-Instruments-datasheet-10254030.pdf) and the datasheet for the new chip (www.mouser.com/datasheet/2/389/stmicroelectronics_cd00000523-1204360.pdf), and I think it will work as a replacement.

How can I erase the chip with UV, is there a special procedure? Thanks for your reply

Sometimes people set them outside in the sun, but it's not as reliable as using a UV EPROM Eraser. You can find them on Amazon, Ebay, AliExpress, Banggood, etc. This is the one I bought, and it has worked so far: amzn.to/3FpPxpm (affiliate link)

Thank you.. Can I Program with the TL866 Plus using windows 11?

I don't have Windows 11 on any of my computers yet, but I will let you know when I try it.

Can this setup detect and fix eeproms and similar memory carrying ics with bugs/faults in the programme that's on the chip?

@JacobExplains 3 жыл бұрын

As long as this reader is compatible with your ROM chip, you can read the binary data off of it. You could then decompile the machine code and fix any bugs you want.
