Wow! I’m sad to say, good luck with this one. I’ve not seen any sign of it having survived. As close as I can get is the binder I have for COS-310 v8.01, but that is for the PDP-8. I’ve always thought it would be interesting to check out DIBOL-11, so would be interested if you have any

Does anyone have the DIBOL-11 software, which was packaged for RT-11 as CTS-300, and for RSTS as CTS-500? My immediate interest is for RT-11, though I have a DECdatasystem-570 that I believe was originally sold with CTS-500, so it would be really nice to get that as well. It would also be nice

The ones you have to watch out for as a rule are those made by Mostek. Not sure of the date when they changed to recipe. If your still in/near PDX I will be getting my Unisite+ back in March and I may have a working Model 29 that you can borrow. -pete On Mon, Feb 15, 2016 at 10:25 AM, Rick

Old MOS Mask-Programmed ROM forgetfulness?

Hi, all, I have a question about old Mask-Programmed ROMs The part in question is the National Semiconductor MM5231. This part is a 2K-bit PMOS Mask-Programmed ROM, generally organized as 256x8, but also can be organized (via a MODE pin)as 512x4 bits. In this particular application, the parts

Re: Tool to convert between Motorola FFP and IEEE754 float formats?

One way to do float format conversions (among a whole bunch of formats) is to use the arbitrary-precision and variable-format float machinery in the GCC compiler (file real.c). It probably doesn't quite give you what you need -- conversion from one format to another -- but I imagine that
