Notice there is no upper bound for any of the chip select or write timing. In either case, ns seems like a curiously short 284. An running at 3. Which I think would just need a couple more address lines added for a It looks like this was done with a PC, but really, it could be modified to work with any computer.
Sat Jul 02, 3: I’d probably try and use an octal bus driver instead of the transistors to drive the LEDs Here is another programmer that does some s they are not all the same. Sun Jul 03, 6: It’s a an entirely different interface with no similarity to 28xx.
Otherwise you will get a lot of consecutive bytes programmed with the same data where you only pressed the button once. Sign up using Facebook. If you have the counters increment automatically after each programming pulse, you will have to debounce the “program” button.
If the device rejects any write cycles that are excessively long, that may help guard against erroneous write operations in cases where a system operation gets disrupted e.
Hello, I have see that. Programmer hardware design is based on Willem Programmer.
They say it compiled under Turbo Pascal, which I think has been released into the public domain. Post as a guest Name. They both work eelrom well. Sat Jul 02, 4: Would be good to clarify by changing the DC bit.
A bit of Googling will turn up lots of do it yourself programmers, complete with the software to run them. If the part uses dynamic latches to hold the address, those latches may only be able to hold their value for a certain length of time. You will want presetable counters like perhaps the 74xx I would not recommend DIP switches, since they are mostly made for very few cycles of life.
The Willem type has the dual advantages of being less expensive and will take an external power supply. I am just curious, but.

This meant they could not work down to DC. How about 28 C 64, or 28[C] or 28[C] Thanks for the answer. That’s not a Willem programmer. I have see that.
