I have a number of 1, 2 and 4 Mbit Flash ROMs available (DIP package). I am selling them for $16 each including programming and shipping. Specify the ROM image that you want programmed.
I can also program PLCC devices (5v and 12v) in addition to DIP devices. $10 for programming and shipping if you send me your ROM chip. I use a dedicated ROM programmer (no hot-swapping on the motherboard), so you can be sure that your ROM chip will be treated carefully. I run an honest shop and can give references.
Peace
