How should I connect the 57c45? In principle, yes you can use a bit EPROM but old style ones are difficult to source and are normally in pin DIP packages so the layout would be significantly different. CMOS Technology file 1. Input port and input output port declaration in top module 2. I think that is dayasheet reason why.

People in your age, can teach how these things actually work, datasheef you have worked with these, whereas people in my age are just in the edge or a bit too late.

Even universities even in UK, where I had my degree have moved to a higher level of things because they must cope with the new technology fast. Dxtasheet transistor not working 2. There are only the basic digital electronics lessons who teach students about primitive stuff like flip-flops and gates etc.

Substituting 27c16 with 57c45, how to?

Things are moving fast and we are trying to catch. D I wish to make the project very educational, it educated me in understating many things of how computers actually work! I’m not sure which clock you want to push for 20MHz but if it’s theplease remember that this is the sequencer for each cycle of each instruction so the actual execution rate will be much slower.

You might be able to get nS from a diode array if you keep the current fairly high but that sacrifices power and logic thresholds.

All the unused address lines should be tied low or to ground and it should then work like an 8-bit 64 address memory.

I don’t think speed is an issue here, in fact the glitch problem highlighted in the 27c61 will be worse with a faster device.

27c6 is the function of TR1 in this circuit 3. I’ve just cleared out a lot of cobwebs and made several spiders homeless. It would be much simpler to use a larger but compatible device such as, and so on but they have more pins so they won’t fit straight in to the same socket.


It gives you a good understanding of what goes on inside a microprocessor and why they work. The actual micro-instruction sequencing is timed by the RC clock in the top left corner of the schematic and it’s speed is very low.

Thanks again for you very informative help! The data is obvious, D0-D7 in both eproms. I see too many students these days who just assume you plug a mouse and keyboard into a box and HD graphics appear by magic. ModelSim – How to force a struct type written in SystemVerilog?

Last edited by neazoi; 12th July at I think I will make the original version on the PCB and later on try modifications to accept the newer eprom, based on the pin connections you indicated. Another thing to notice is that both eproms are connected in parallel, if I could find a datasheft wide eprom I could use only one.
