Hook up power source (adapter or usb cable). Always doublecheck the chip is correctly in place. Warning: inserting the chip wrongly may damage both the chip and board. Then press down the handle to secure the chip in place. Ensure that the chip is inserted at the BOTTOM and that all the chip legs fit correctly. Make sure that the Notch points UP towards the handle (see green circle). Insert your 27128 or 27C128 chip like shown.

make sure to keep this at 5V normal position. Probably the only jumper you actually have to set manually yourself When your are READING your eproms. to write/burn eproms you will need a power adapter at 9V, 12V or 15V to supply the 6V needed for writing. Note: if USB cable (5V) is used you can only READ eproms. If your Willem was sold as a 'usb'-kit it will most likely be in usb position and if your got a 'poweradapter'-kit it will be in that position.

Select software version to fit board (default). This is the default posistions, so with a little luck you wont have to touch them at all. So far all the chips ive used worked with 12,5V.Д®nsure that all these pins are in normal chip usage position (normal usage for this chip of cause). If you get a chip without visible Vpp try the lower 12,5V first. Note that you MAY get some chips that require the higher 21V. 27C128 usually use 12,5V and this is usually the default of the board. Note how it usually says on the chip what the Vpp is (see RED circle). With a little luck the rest of the setting on the board wont need to be change as the 'factory settings' works quite well most 27128/27C128.Д«ut just in case here is a step by step check:Д¬hange the correct chip pattern to tell the board that we are using a 27C128 chip.Д¬heck correct Vpp (programming voltage).

Then you will get the correct setup for your chip So open up EPROMS45 program and click on the 'Device select' button then select 27C128. The Willem software will do that for you.

Reboot you pc and double click the xp_stop_polling.reg if needed (donno about Vista).ДЇirst you need to find the right setting for your chip.

First install the software (like setup_98d5_PCB45.exe). Then connect the Willem board using the (hopefully) supplied parallel printer cable (DB25). First turn off you pc and remove the power cord from the pc too. You have gotten your Willem programmer board and some empty eproms. But how do you make sure that the odd used chip 'pulls' you got cheap off ebay will workВ ? Use 6V onlyВ ! but the non-'C' part like 27128 do not (only need 5V). did you notice the difference between 27128 and 27C128 (The 'C' part) while reading that? The 'C' part like a 27C128 need 6V. you can fit a smaller rom quite easy into a larger Eprom if needed.ДЄfter reading that.

there are a couple roms that has a different size. So hunting down a couple of 28 legged 27128 or 27C128 eprom chips (cleaned/erased/empty) and you are ready. you can only tip them once.ДЄmstrad rom are usually 16kBYTE. forming a unique pattern that makes a amstrad chip. So to make it really simple: pretend that you have 16000 dominoes. unless you have special hardware (eprom eraser).

Used a Willem v4.5 board and software 0.98D in the pics, but the other version boards/software works just as well.Д®proms is bacisly like a cd-rw. A Willem Eprom programmer board v3.x or better (+cable & power adapter).

8 Then you will get the correct setup for your chip.
