Re: [M100] CP/M Expander

Ken, Sounds like you're on to something fairly promising! If there's any assistance you think you might need (hunting for technical info on the NEC side, perhaps), I have quite a bit of resources at my disposal. Good luck sir! Gary On Wed, Jul 26, 2017 at 4:52 PM, Ken Pettit

Re: [M100] CP/M Expander

Hey Gary, Actually, thinking about it, even generating the WR signal shouldn't be an issue. I could just detect CE active with no RD at the proper location. This would be really easy. Trying to decode the opcodes to generate WR is complicated by the fact that the opcodes produce varying

Re: [M100] CP/M Expander

Hi Gary, This should be manageable still using only the RD and CE signals. Without the ALE, it is a bit more work to track the bus activity, but not impossible. If the Woolly board has an FPGA on it, then it would certainly be no issue. But I'm investigating if I can use a Xilinx

Are there docs about exactly what port writes were necessary for the bank switching? I don't have one just curious about the architecture. S Sent from your iPhone. > On Jul 26, 2017, at 6:35 PM, Gary Weber wrote: > > Ken, > > While the NEC "All Ram" mode is as easy as

Re: [M100] CP/M Expander

Hi Mark, I looked at the ESP32 and ESP8266. The problem is that the modules are too big for the OptROM socket. And trying to use just the chip vs. using a module, it requires adding external components for RF and then getting FCC testing done (10's of thousands of dollars). With a module,

Right, and I came up with the name Woolly because a module like that inside the M100 would pretty much be a Mammoth, which is of course pre-historic, much like the Model T laptops. Ken On 7/12/17 6:37 AM, Brian White wrote: Ken was refering to the names of the things. nads is slang for

Great Ken. Changing thread to "CP/M Expander" Is it really possible to fit all that on OptROM form factor? Would it need a heap of wires soldered to motherboard? Philip On 12/07/2017 7:14 AM, Ken Pettit wrote: Downloaded the remem.bin file and ran CP/M under VT 1.7 on Linux. Works great!
