Re: [M100] Remem programming guide

Thanks again! No question, RAM disks are usually the fastest form of data storage; on the other hand you can take your FAT-compatible SD card or USB stick over to your PC where 'transfer' is convenient and also pretty quick... A REX or even something equivalent to a modified XR4 could probably

Mike here is the latest programming Info doc for remem. I think the advantage the remem offers is super fast ram disk. Basically the cpm disk is memory mapped. Other than that remem is way overkill and complicated... Steve ReMem Programming GuideV4_1.doc Description: MS-Word document

Re: [M100] It's Alive!

12 MHz?? You must mean one of the late Turbo versions. I've got one or two somewhere, think VT will run on it? ;-) I suspect he just hadn't noticed the speed button; where is it on the real M100 ? m - Original Message - From: "Ken Pettit" To:

Re: [M100] It's Alive!

Actually, when I was testing AsciiPixels a year and a half ago, I noticed VirtualT was a fair bit faster than a real M100 when it came to LCD controller access, so I added additional delay to the emulation in 2.4MHz Speed setting. Perhaps It was a little too much delay. If you run with Max

...When are you going to speed up Virtual T? Not necessarily a bad thing - If it works on the emulator it may well work on the target hardware :) On 7/9/17, Mike Stein wrote: > Hey Ken, > > When are you going to speed up Virtual T? The guy in the video says it's >

Re: [M100] Alternative he for cpm

Any of those would solve the 64K RAM issue, even REX2 as it stands I believe. What about RAMdisk/Disk & transferring to the outside world? Mike Stein pointed me to some micro SD adaptions out there, such as this: https://www.4dsystems.com.au/product/uVGA_III/ Could an OptROM sized board

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

Thanks Gary Are you meaning to use CP/M on a real NEC? That would depend on whether any new hardware developed will apply to the NEC. Once it works on a real M100, then the BIOS changes required for NEC would be relatively minor I should think. I'm curious as to what sort of CP/M programs

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

Hi Roger I did those as part of the installation. Starting off with the assembly listing of CP/M 2.2, I was able to build it up one step at a time. That's different than the traditional Regeneration process of pulling the binary down from a floppy disk. Philip On 9/07/2017 10:45 PM, roger

Re: [M100] It's Alive!

Hi Jason, Welcome to the world of M100 BASIC programming! I looked at your code ... didn't run it yet. The basic structure looks good. Some advice as far as variables that would speed things up: 1. The variable names "GRID" and "RGRID" are 4 and 5 characters long each. BASIC only uses

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

An amazing thing indeed... However, if all you want/need is to run some CP/M program(s) or work with old CP/M data disks there are quite a few CP/M emulators out there for pretty well any platform, as well as programs to convert among different disk formats. Unfortunately the issue with

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

Philip, It is an amazing thing you have done. I used to have an 8201A with the PIC-Disk system that provided a full blown CP/M operating system. After losing that original computer and disk system to theft, I was left without access to 20 disks of CP/M files and programs and back-ups of my

[M100] Alternative he for cpm

Building on Philip's success i could suggest We can revive an old hw design for external ram based storage...the rampac ... which plugs into the system bus. Easy to make. Works on m100 t102 t200. Or A variant of quad could provide ram for both memory banks plus ram disk. M100 only. Lastly

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

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
