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

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

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

After I posted that comment on Small C, I realised there's undoubtedly a CP/M version of Small-C. An advantage of doing it in CP/M instead of native M100 mode is you have about 55KB in CP/M to host the compiler, source & output files, whereas in M100 mode, less than 32KB. Unless of course you

You understand correctly Steve. Map 2 is the same as Map 1 except that it brings in 1KB of Remem at a time which looks like a disk Track to CP/M. I know where my disk read/write routines are and I know where the 1KB block appears, so it's quite safe. I've tailored the BIOS to suit Remem in

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

Thanks Ken. Only possible because of Virtual T - I wouldn't have a chance in hell without it. Hardware: I'm thinking a 64KB of RAM for CP/M and 512KB say for a RAMdisk. 64KB would make it easy to switch in & out CP/M & return to M100 mode, but it could be done like REX2 and just switch in

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

Thanks Steve Yes, bank switching to std ROM for interrupts. Also means ROM calls from Basic, C or any language can easily be made as long as it's finally despatched from himem (above 8000H). A memory map should answer your queries: 0- 7FFFH M100 ROM 8000H - H CPM RAM

Hi Philip, First of all, WOW! Excellent work! I wasn't aware you had been working on this silently in the background. Yes, the remem.bin binary should work with any variant of VT 1.7. The only real compile differences between platforms is the GUI, and most of that is hidden by the FLTK

Wow! Phil you've been busy! I'll have to think about what you're doing with the memory banks. I assume you are also in all ram mode? Are you bank switching to std Rom? In terms of hardware... not easy to map to rex. Rex2 maybe. But one could imagine a hybrid that uses the rex technique for

[M100] CP/M has arrived for the M100

Well, it's arrived as far as Virtual T. It will need a new hardware device developed to use on a real M100. Over a decade in the making (started in 2006), I present 64K CP/M 2.2 running in VT with Remem enabled. The Remem is used as RAMdisk, to emulate two disk drives of about 241KB each.
