I would be interested in hearing if any Atlas software survives. Sadly, it appears that the Titan software has been lost as well. The Computer History Musuem has paper copies of Stretch diagnostics, which someone had been working on OCRing, but I've not heard anything about that effort for over a year. 7090/94 is in better shape, and there are copies of software for it, including FORTRAN, running in simulation. Personally, I'm very interested in seeing B5500 running again. I'm hoping the MCP tapes we have in the CHM archives are recoverable. I have scanned most of the software listings CHM has in the archives and put them up on bitsavers. There is also someone working on an implementation of the CDC 6600 derived from the original engineering drawings. Hans Pufal was working on microcode level simulation of the 360/30, working from reverese-engineered microcode from the Field Engineering documents.Article: 145405

Not so much later, it was sold. I then rediscovered programming some years later, first on an HP 9810A, and then OS/360 Fortran. It would be nice to try the B5500 again, though software emulation (instead of FPGA emulation) would probably be just fine.

I thought someone had copies of the microcode, but then again maybe that is what they meant. Are there no copies of the actual ROS available in museums? -- glenArticle: 145413

If not, you'd have to cob up some Algol compiler to cross-compile ESPOL, and then bootstrap MCP, Algol, and ESPOL using that. Difficult, but do-able, once the code gets OCR'd (or, having looked at the listings, more likely re-keyed.)Article: 145417

In the same sense that emulating them in TTL chips is a challenge -- it's a comparable task, but done by writing VHDL or Veriolog instead of by using a wire-wrap gun. If you really want to embed a simple computing core in an FPGA project, they're available off-the-shelf in libraries and can just be stuck in as needed. But that's not the goal of these projects. -- As we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.

Sun has released verilog code for more recent SPARC processors. It is likely that those, along with the rest of an actual system, would be too big for even the larger XC3S devices. Maybe the Spartan 6 is bigger. Another one to consider is the Macintosh Plus or SE. That is, 68000 based Mac. Also, 68010 or 68020 based Sun systems. -- glenArticle: 145420

Hi; We are trying to program a CFI Flash (Numonyx TE28F320J3D75) using the flash programmer of Quartus II/EDS 9.1. We followed the instructions given in the User's Guide (from february 2010 !), and the programmer is reading the CFI table correctly, but when it comes to actual programming, it stops at 0%, with the following message : " Program failed Error code : 4 in .....nios2flashprogrammer.exe .... " In parallel, we have been running read and write tests on the flash and they are passing. Thus we suspect that something may be wrong with the flash programmer... would you have any idea of what we need to check and what we can do to have a bit more visibility of what's going on ? Best regards, JFArticle: 145424
Could some Xilinx ISE guru provide some hints for my problem ? I am trying to synthesize a simple 4K RAM block with Xilinx ISE. About half- way through execution, I get an error message, inside a Visual Studio dialog box, stating that xst.exe ( the Xilinx synthesis executable) has encountered a problem and would I like to debug ? The Xilinx ISE is running on a XP machine. Any hints, suggestions would be of immense help.
