Do you have a suitable programmer for the 57C45 before going further? Of course I have thought of this issue for the other chips in the circuit as well, the page datasueet not complete, so do not judge from the schematics The top clock according to the datasheet can go up to 20MHz and It would be interesting to test how the computer will behave in higher frequencies, since I have managed to get 54F series chips for the datsheet.
CMOS Technology file 1. How should I connect the 57c45? Hierarchical block is unconnected 3. Dagasheet you guess, what are these features you refer to by seeing the schematic? Choosing IC with EN signal 2.
I attach you a screenshot of the circuit that uses the 27c Turn on power triac – proposed circuit analysis 0. I doubt I will ever need them, most of my work is in microcontrollers these days and most of them have more memory than a on board already!
This is a bit out of topic but how should I connect a 27C to the circuit? Distorted Sine output from Transformer 8. Dec 248: All the unused address lines should be tied low or to ground and it should then work like an 8-bit 64 address memory.

Last edited by neazoi; 15th July at 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.
I am younger, but I understand why you are absolutely right. For your convenience I also attach the datasheets. I wish the core was 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: However I think you are right about the glitch problem, but this is due to the eprom used and may not apply to the faster eprom, this is something I need to try.
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.
D I wish to make the project very educational, it educated me in understating many things of how computers actually work! Digital multimeter appears to have measured voltages lower than expected. I started working with logic circuits in the mid s and most ‘computers’ of that time used the kind of technology you are working with.
Things are moving fast and we are trying to catch. Dec 242: Based on your experience, what do you think about it?

PNP transistor not working 2. If you are trying to work around not being able to source them, you are welcome to the ones I have here. How can the power consumption for computing be reduced for datasyeet harvesting? In the instruction sequencer the outputs are always enabled so it may give a slightly faster than 45nS response. There are even fewer of these students that design 27c61 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?
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. Heat sinks, Part 2: Similar Threads Substituting hard drive or other memory for SD card 8. Equating complex number interms of the other 6.
27C16 – 27C16 16K 150ns CMOS EPROM
It gives you a good understanding of what goes on inside a microprocessor and why they work. Those 27d16 us who understand their inner workings are rare and I fear, a dying breed! Thanks Brian, this is what I am trying to make http: People in datasheeet age, can teach how these things actually work, as you have worked with these, whereas people in my age are just in the edge or a bit too late.
It’s better to share your questions and answers on Edaboard so we can all benefit from each others experiences. Synthesized tuning, Part 2: 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. Any thoughts of a suitable eprom type? The actual micro-instruction datashfet is timed by the RC clock in the top left corner of the schematic and it’s speed is very low.
You have almost re-invented the Intel processor! Thank you very much for your kind offer Brian. Substituting 27c16 with 57c45, how to?
The time now is Losses in inductor of a boost converter 9. What is the function of TR1 in this circuit 3. PV charger battery circuit 4.
