Repeat Step 3 for U6B.rom, marking it "U6B" (HOT DEAL) US 32.40 Buy Main Board BIOS Programmer Spi-25xx-pcb5.0e Multifunctional Willem Universal EPROM Burner From Vendor FAHO Store. Insert a 27C400 eprom into the eprom programmer and burn buffer to the eprom.Īpply opaque sticky label over the eprom window and mark it "U6A" Perform a swap BYTE operation on the buffer contents

Start up eprom programmer software with 27C400 device selected. Repeat Step 2 using U6B_tmp.rom to create U6B.rom Select Done and a message box will appear: 524288 bytes from 2 files were concatenated to "U6A.rom"

Repeat this again, append source file U6A_tmp.rom to U6A.rom Type in destination file for a blank rom file to be created (eg. some chips will only program with a higher power rating, which the USB connection simply cannot provide. To do this, in WinHex select: Tools -> FileTools -> Concatenate Maybe, as per above you need the dual power version of the willem programmer. Now, we're going to copy the contents of addresses 00000-3FFFF to 40000-7FFFF for U6A_tmp.rom Step 2: Fill addressable unused memory space for both eproms this is the eprom programmer to use this should be good enough mainman CPS2 Person., Joined. I do have a Voltage Changer/LED button, the choices are: Normal, 15V, 21V, 25V. In WinHex select: Tools -> FileTools -> Dissect -> Wordwise (16-bit) It is powered through the USB, it is specifically the: Enhanced Willem Universal EPROM EEPROM programmer.

#Willem eprom programmer manual dual power how to#
In answer to the Computolio's original question, here's how to burn a kickstart eprom set for an amiga a1200 in 4 easy steps: So I think this particular eprom programmer is one to avoid. Vcc should be around 6V but due to the flawed design it only provides about 5V. It seems to have problems providing the required voltage during the eprom programming stage, ie. In particular the version of eprom programmer that is only powered through the USB port. Having investigated a bit further on some forums, I've changed my opinion of the Willem eprom programmer. You put the 27C400 eeprom in the 42 pin socket but start at pin 2 of the socket. This is a description from the sellers website. The converter board (are you referring to the 40/42 pin adapter board) comes with it I believe. Make doubly sure as converter boards can cost more than EPROM programmers. I think you may require a converter board for the unusual pinout of the 27c400 chips.
