[Coco] ROM Development question

[Bill Nobel]

I’ve also got the same programmer coming (paid $55, but oh well Lou..)  I also went to the extent of getting a eprom eraser as well ($14 from China) does 8 chips @ once.  I have used a few different programmers in my past. You just need the raw image (either extracted from a real 1, or asm build)  I compiled Grants rom with as9 and haven’t been able to try on this burner (as I’m waiting for shipping)  There is also another rom image & circuit to try as well

Another version of 6809 sbc, but uses smaller rom image (no basic, monitor only), and slightly different base 6 chip design (before rs232 connection) it has a slightly more controllable memory map vs Grants base.

I'm using ST M27C128-10F1 EPROMs, also purchased off eBay. Two sleeves of five for $17 total, shipped. I've successfully burned a custom ADOS-3 ROM for use in a Disto Mini Controller that includes a socket for a 28-pin EPROM.
