Things are moving 271c6 and we are trying to catch. 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. The data is obvious, D0-D7 in both eproms.

Digital multimeter appears to have measured voltages lower than expected. That is true ttl but I think the speed can never go higher than a ns eprom, even if using F series chips for the decoder.

The top clock according to the datasheet can go up to 20MHz and It would be interesting to test how the datashwet will behave in higher frequencies, since I have managed to get 54F series chips for the circuit. Of course I have thought of this issue for the other chips in the circuit as well, the page is not complete, so do not judge from the 271c6 Do you have a suitable programmer for the 57C45 before going further?

Thanks Brian, this is what I am trying to make http: The address seems obvious dafasheet, use only A0-A5 of the 57c45 and ground the rest of adress lines. That does not apply only in datasgeet. If you are trying to work around not being able to source them, you are welcome to the ones I have here. I think you might have problems with this device, obviously it has greater storage capacity but it also has other features which your original circuit may not cater for.

You have almost re-invented the Intel processor! For your convenience I also attach the datasheets.

Dec 242: How do you get an MCU design to market quickly? In the instruction sequencer the outputs are always enabled so it may give a slightly faster than 27v16 response. Based on your experience, what do you think about it? Thanks Brian i will follow your suggestions and design the PCB that accordingly. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. I wish the core datashee my design, but at least I have already made some modifications and I will do more, so hopefully at the end I will take some credit for this as well: Part and Inventory Search.

Distorted Sine output from Transformer 8. 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. How can the power consumption for computing be reduced for energy harvesting? There are only the basic digital electronics lessons who teach students about primitive stuff like flip-flops and gates etc.

I attach you a screenshot of the circuit that uses the 27c Hierarchical block is unconnected 3.

The time now is You might be able to use PAL devices but again these need a different programming technique. Losses in inductor of a boost converter 9. PV charger battery circuit 4. There are even fewer of these students that design their own processors as parts of their final year projects and when the final open-day presentation comes, they take the risk of being asked “why didn’t you do that on a modern fpga?

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. The problem is not sourcing the eproms but speed as I mentioned.

That is why these forums are so important; listen, talk and learn from older ones D I wish to make the project very educational, it educated me in understating many things of how computers actually work! Primarily, it has a latched output although the data sheet suggests it may be possible to bypass it. Another thing to notice is that both eproms are connected in parallel, if I could find a bit wide eprom I could use only one.

Substituting 27c16 with 57c45, how to?

Similar Threads Substituting hard drive or other memory for SD card 8. I started working datzsheet logic circuits in the mid s and most ‘computers’ of that time used the kind of technology you are working with.

My final idea is to completely replace the two eproms with a 1n bit diode matrix and a address decoder out of a few demux chips. Synthesized tuning, Part 2: ModelSim – How to force a struct type written in SystemVerilog?
