Re: R65F11
Dwight, I would be very interested in your NC4016 experience. I did collect a NC4016 STD bus board a while ago from ePay, and have successfully spoken to it via a terminal - It would be fun to add storage, but I have no idea where to start :-) And no doco..:-/ Kindest regards, Doug Jackson em: d...@doughq.com ph: 0414 986878 Check out my awesome clocks at www.dougswordclocks.com Follow my amateur radio adventures at vk1zdj.net --- Just like an old fashioned letter, this email and any files transmitted with it should probably be treated as confidential and intended solely for your own use.

Re: R65F11
I have one of the NC4016 boards ( I forget which one ). I added a XT floppy controller and a XT MFM disk controller. I made some other hardware for doing byte stuff faster. Using address -1, I could access it faster as a short literal. I had a 8 bit barrel shifter there. It came in handy for the XT controllers. The processor was fast enough that I had to add delays to the code to the floppy controller. It would run faster than the floppy controller could provide status. Still, I was using it with direct processor access and the controller was really expected to be used with a DMA transfers in a XT computer. The MFM hard drive controller was much easier to deal with. National also had a bunch of stackable computer modules. One of these modules had the NSC800 processor with a Forth ROM built in. Rockwell liked Forth and used it quite a bit in their development system as well as having it on their AIM 65 machines.

Just over the last few days I have been going through old issues of ETI (Electronics Today International, the original Australian version) from 1985/86 that included a series of articles on the R65F11 and R65F12. I have long wanted to play with one, as far back as the 80s. It would be really neat to play with, especially with the development rom. Alas, I have WAY too many "neat to play with " things surrounding me now. But it's a neat gadget. I hope someone takes it and does something neat with it.

Re: R65F11
Rockwell also had an RSC-FORTH Kernel and development environment ROM set for the R6501Q, which is a similar 6502-based processor meant for embedded applications. http://www.smallestplcoftheworld.org/RSC-FORTH_User%27s_Manual.pdf Here's the RSC-FORTH manual, which covers the different types of RSC-FORTH.
Re: R65F11
WOW!! I Have one of those ETI boards, and I based my final Electronics Engineering project on its big brother, the 65F12. >From memory, I spent days trying to understand why you had to issue a HEX 1800 MEMTOP command before using the disk. ETI Suggested that it was because the system had to know where the top of memory was, but it was because of a bug in that version of the kernel. The 65F11 had all of the headless primitive in kernel rom, and used a development ROM that contained the higher level words. I Loved the concept, but the silicon was expensive and as it turned out, rara. Nobody knows anything about these chips. At Uni, we hav Novix NC4016 dev boards with FDD support - they were FAST... One cycle could see the CPU read the next instruction, write a byte to the stack, and write a byte to I/O - all because it used three (or 4) separate busses. I'm here in Australia, and would merrily give it a home. :-) Kindest regards, Doug Jackson em: d...@doughq.com ph: 0414 986878 Check out my awesome clocks at www.dougswordclocks.com Follow my amateur radio adventures at vk1zdj.net --- Just like an old fashioned letter, this email and any files transmitted with it should probably be treated as confidential and intended solely for your own use.

Anyone remember the R65F11? It's a Forth microcontroller: 6502 processor with a Forth kernel in ROM, from the mid '80s. I was going through some old stuff in storage (looking for something else) and found an R65F11 with the development ROM and some documentation for building a development board. Looks like a fun little project... I have plenty of projects. If anyone is interested, it's free for actual cost of shipping (could probably go in a U.S. Priority Mail envelope or small box, not sure about overseas options). The backstory: in 1984 I was working for a startup company, and we were looking at various microprocessors for use in a new product. Being a fairly skilled journeyman Forth programmer, I was advocating for the R65F11. I managed to talk the Rockwell sales rep into giving us the development ROM (usually not easily available). We ended up going with a 68000 for the project, and I ended up with the R65F11.
