Hi Yes, I've seen that information. What the diagram is missing is pinout information on the SPR000. There is not enough information available to make a useable SPR000 project. A brief datasheet would probably be sufficient. Or an actual SFD2000 PCB so I could reverse engineer the...

I've had luck here: https://www.ebay.com/sch/i.html?_ssn=351_windsor This would be good insurance as a SP0256 tester: https://www.ebay.com/itm/275386401515 My next goal with DAISY256 is to allow non-AL2 SP0256s to access the 59 allophone information via external ROM. Thus, non-AL2 SP0256s...

I have four (4) DAISY256 PCBs leftover if anyone wants to build and experiment on their own. I will send you one of the boards if you're willing to build. Especially if you're interested in tweaking CTS256 firmware to support other TMS7xxx and TMS7xCxx variants. I am satisfied that the...

Hi The situation for TMS7000 tool chains isn't great but it exists and works. The link above is for a classic Radio Shack CTS256/SP0256 text-to-speech (TTS) circuit of which there are several on the internet. What is special about the link is the code is for a CTS256 expansion ROM including a...

Hi Some specific TMS7000 related documentation I am looking for but cannot find. any technical data (data sheet, application note, design guide) on SPR000 (DIP40) and/or SFD2000 (PCB serial speech ROM to parallel EPROM) Related threads on retrobrewcomputers.org...

The PD32 project is updated and ready to go. All the files are on Hackaday and teed up for someone to build and test it. There doesn't seem to be much sustained interest in an NS32K projects, and I think PD32 would be the simplest approach. Hopefully someday (soon) someone picks up the torch...

The NS32016-BC PCB is in trace routing. I experimented with a 2-layer board just to see if it would route, and it did solve on its own which is a good sign. However, with the board being so physically large and with some high-speed signals, it probably has to be 4-layer for stability and...

Yes, that is how the story goes. No EDA tools used. Literally a wire-wrap design on a prototyping board and a *hand recorded* netlist. Apparently manually typed in one connection at a time. What you see represents a whole lot of work by Bruce Culbertson. Nothing was automated. I am very...

More history in context on Bruce Culbertson NS32K small system. Check out the data on USENET: Nov 11, 1988, 8:05:27 PM https://groups.google.com/g/comp.sys.nsc.32k/c/Ef9W5DR-1ZA/m/emb1Y7NQsBMJ fascinating read!

Hi I do have some additional background on the Bruce Culbertson NS32016 project. Apparently, it was done in the mid 1980's and posted in 1989. It ran Minix and included sources for drivers, etc. to get it running and some tools. Also, the schematics and PCB layouts never existed since Bruce...

Hi Looks like a project page on Hackaday for Public Domain 32000 is starting to take root. Recent activity and people signing up https://hackaday.io/project/189965-isa-bus-slave-ns32016-processor-board

DM me to discuss

Hi Jeff, did your project ever advance to the prototype stage?
