No, Ken. That's something else. But, then, you guys do get a little mired in miniature rapture, hey? Gene Corrigan flowcharles...@gmail.com >>>175 Market Street, 407<<< Charleston SC 29401 +843.870.3235 > On Jul 11, 2017, at 9:09 PM, Ken Pettit wrote: > > My Initial

Oh, and the name I gave to this design is "Woolly". It would be the Woolly board. :) Ken On 7/11/17 4:39 PM, Ken Pettit wrote: Hi Philip, It is possible. No wires needed, just plug in the module. I developed a board for a client that has this much functionality on it and it is small

Hi Philip, It is possible. No wires needed, just plug in the module. I developed a board for a client that has this much functionality on it and it is small enough that the user wears it under their foot (along with a big battery and charger coil). The solution I am thinking about would

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!

Does anyone happen to know the Molex part number that the OptRom uses for inserts? I'm reffering to the part that the PROM wraps around and is inserted into the OpeRom socket. Kurt

Downloaded the remem.bin file and ran CP/M under VT 1.7 on Linux. Works great! Now I just need to get my super-cool OptROM form-factor FPGA + Microcontroller + SRAM + WiFi + Flash board I want to build done. So much to do ... so little time. Ken On 7/8/17 8:28 PM, John R. Hogerhuis wrote:

Thanks Steve. I'll have to look at this. File mode 4 has be baffled since I was only aware of three modes. 1-write, 2-append and, 3-read. Since it already exists in LaddieAlpha I may just leave mComm alone, Kurt On Tuesday, July 11, 2017 11:06 AM, John R. Hogerhuis

Re: [M100] CP/M has arrived for the M100

Effectively, it allows simulating random "block" access on a TPDD file. It's not the either the TPDD-1 or TPDD-2 sector access mode. It's an extension Ken invented to the File Mode protocol. Here's the Laddie code: private void RequestSeekExtension() { // Seek (Ken

Re: [M100] CP/M has arrived for the M100

John, Is the SEEK command you are referring to similar to sector access mode or is it an add on to the original TPDD protocol? Kurt On Tuesday, July 11, 2017 10:43 AM, John R. Hogerhuis wrote: On Tue, Jul 11, 2017 at 10:38 AM, Stephen Adolph

Indeed you are correct, they do. You sacrifice Bank #2 and can have H-7FFFH be all RAM.I've done it actually, by copying the system ROM contents to Bank #2 and then invoking the appropriate OUT commands in machine language. However I guess I was looking at replicating the original

Hi Roger Well there's really only the serial & printer ports remaining. All other I/O is done. I thought I'd wait until any hardware is developed to do those. I've fully implemented interrupts, while CP/M doesn't use them - we can, & make use of the system ROM routines for I/O. After Import &
