| | **TCPU v0.3 and 0.4** |
| | |
| | //August 2019// |
| | |
| | So its been a couple of years, work and life have got in the way. Version 0.3 was a total dud....so lets move straight onto v0.4 |
| | |
| | Per the last update I have removed the ECB connector. I also settled on ZIP memory TC514400AZ's ( [[https://datasheetspdf.com/pdf-file/1091701/Toshiba/TC514400AZ-60/1|https://datasheetspdf.com/pdf-file/1091701/Toshiba/TC514400AZ-60/1]] ). |
| | |
| | The result is that I now have a Trransputer + 4Mbytes of memory working (happy day!) The 0.4 board is not without issues so needs a bit of TLC. The GND somehow didn't connect to the memory. Also the AD11 on the memory didn't get connected to the bus. Lots of head scratching on that one with various errors. I am also going to move some of the resistors closer to the 74ACT86 and remove some of the jumpers that just aren't needed. |
