I've been playing around with various designs for one to replace the now defunct Super E-Burner on the Atari 8-bit. I suppose it's not really the burners you should be looking at but the ROMs themselves. The vast majority of low-cost burners hook up either to a PCs parallel or serial ports and pretty much do the same job - just check for those that will program the EPROMs you're looking to burn. Most recent EPROMs have a 12.5V programming voltage. Some of the older of the lower capacity EPROMs (such as the 2716) have a 21V programming voltage. There are a lot of kit designs on the net, if you want to save money and know one end of a soldering iron from another (you'll soon find out - pain and the smell of burning flesh usually means you have to hold the other end). There is one design that a lot of people seem to use. It only handles the 12.5V EPROMs but that shouldn't be a problem. It's also much less complicated to build than many I've come across. http://www.zws.com/products/epromr2/ I did design an EEPROM burner for the 8-bit Atari which used the joystick ports as a kind of serial interface. Posted it onto an electronics message board. Never built it but the idea was sound. EEPROMS usually only have a single 5V supply, so they are even easier to write to and design burners for as there's no need for an extra power supply (some Flash ROMs also use a single 5V supply, although many still use a 12V programming voltage). Hope these little didbits help :-) Regards, David ----- Original Message ----- From: "Ben Larson" <benjamin_e_larson@xxxxxxxxx> To: <stella@xxxxxxxxxxx> Sent: Wednesday, March 24, 2004 7:59 PM Subject: [stella] EPROM burners > Hey everyone.
