Title: EPROM burners
Post by: pbj on February 25, 2022, 10:29:32 pm

I’ve made some bad decisions lately but that is another story for another day.

Are any of you using an eprom burner that you like?  I’d like to hear about it.  I need to burn 42 pin 4MB chips.

 :cheers:

following.
I have a TL866II + from alliexpress on a slow boat.
it's supposed to be able to burn bios chips so hope i didn't buy a paperweight.

i second the TL866 series. It does most 27 series 42 pin chips with no issues including the 27C4096.

if you have the older "866 mini" version, 27C160 or 27C322, or the TSOP 29F016 or 29F032 on a TSOP adapter board, you need to use an adapter to swap out the memory banks to write them. it does support those 4mb versions of the chips, so you just break up your rom into 4mb chunks and swap the A18 and A19 write banks... and will do up to 16mb chips this way.

i'm not sure if the newer B or CS versions have fixed this issue or not, but if you need to do 8 or 16mb chips, you can.

Are you using an adapter with the TL866II+?  I'm only counting 40 pins on the chip socket.

sorry... to clarify, yes i have to use an adapter to do the 42 pin chips as i have the original 866 mini model i bought way back.

i wasn't sure if the new revision models included the ability out of the box.

Seems annoying as hell to flip those switches between banks.  I'm looking at the TOP2013 because it has enough pins to hold the chip without an adapter.

i bought the 322 to replace my top2003. the china company that made the top2003 essentially stopped updating the software and left it in a semi broken state. there was no support to use it with even windows XP without a bunch of effin around using compatibility mode and sketchy giveIO drivers installed to have the software connect directly again through XP. I gave up on it after that.

Can I just pay you to burn a couple for me and then I can decide if this is something I actually want to mess with?
