Re: [M100] CPM?
Ah, CP/M ! It's something like the Loch Ness Monster of the Model T-community. A lot of people believe it exists, Few have ever seen it, But until the scientists of Jurassic Park come along It continues to elude us.

Re: [M100] CPM?
If it doesn't, we need a clever developer who is very intimate with the Model 100/200 architecture and the 8085 to port it :) Someone in the Color Computer community ported CP/M to run under OS-9 on the 6809. If that can be done, it seems that getting it to run on an 8085 would be plausible. Date: Mon, 1 Jun 2015 00:44:09 -0300 From: louis.l...@gmail.com To: m100@lists.bitchin100.com Subject: [M100] CPM?

Re: [M100] CPM?
What is challenging for the M100 is the dependence on disk, and the requirement that it act like a standard FDC. TPDD1 can do this, but not TPDD2. M100 on it's own would struggle also because it has only 32kB of RAM. The lower 32kB would be unusable, save for some routines. We've been discussing this for a long time. Options for 64kB of RAM: - REX2 - EXTRam - XR4 Options for FDC: - TPDD1 - a software solution on something like LaddieAlpha - NADSbox with modified firmware On Mon, Jun 1, 2015 at 7:59 AM, Joe Grubbs wrote: > If it doesn't, we need a clever developer who is very intimate with the > Model 100/200 architecture and the 8085 to port it :) Someone in the Color > Computer community ported CP/M to run under OS-9 on the 6809.

Re: [M100] CPM?
Are you sure it's not CPM for the TRS-80 model 1? I had a copy of that but it required a switch on the model 1 that swapped out the ROM with a block of memory by fiddling with the address lines. This gave CPM the contiguous block of RAM starting at address that it needed to run. I had this running on my model 1 a long time ago but switched to a Kaypro 2x soon after (which still runs today.)

Sector access via large files and seek command is already implemented in LaddieAlpha and Nadsbox. -- John.

Re: [M100] CPM?
He's basically built an emulator/VM that runs in OS-9.

Too slow at WordStar to be usable though. "Fast and furious" :-) Close though! Maybe some serious optimizations in his virtual machine can make it fast enough. I'd guess he's straight mapping 8080 instructions to 6309 code. Depending on how he's handling register mapping and whether he's doing any cached code translation versus straight mapping/interpretation there should be thing he can do.

Re: [M100] CPM?
A cousin of these devices, the NEC PC-8500 is a pseudo-CP/M computer. It has WordStar-To-Go built-in and it can be made into a full-fledged CP/M computer by adding the 32KB memory expansion cartridge and the floppy disk drive/drive interface. Just an FYI.

Re: [M100] CPM?
Too slow for Wordstar cp/m? Back in the day, I used an Epson PX-8 with dual disk drives and a 128K RAM pack -- all of which I still have. It ran a ROM based Wordstar. If you had a 4 page document and you made a small change in the middle of it, you could hit return then go fix lunch, eat it at a leisurely rate, then fix and drink a cup of coffee and MAYBE it would be finished thinking through the change. And I am exaggerating only very slightly. It seems a little better on my NEC PC-8500, but I have never done any long documents on it. David Sent from my iPad > On Jun 1, 2015, at 10:02 AM, John R.

Re: [M100] CPM?
The CP/M machine that I used as an RPFT was 8085 based. I have seen more versions for the 8085 than for the 8080. Frederick Whitaker Sent from my iPhone On Jun 1, 2015, at 11:50 AM, "John R.

Re: [M100] CPM?
Personally I find the Model 100 fast enough for even fast typing. The CP/M machine was very slow. I wonder if the problem was CP/M.

So maybe I'm spoiled :-) Anyway, for those interested there is a project to port CP/M to the Model 100 w/ 64K all-RAM hardware. MTCPM. I host a mailing list, subversion server for it. Steve Adolph created the necessary hardware. Ken and I created external disk service software. Phil Avery has done most of the actual CP/M porting work so far. http://bitchin100.com/wiki/index.php?title=MTCPM More devs with time to work on the project are always welcome. -- John.
Re: [M100] CPM?
Wow, wiki page last updated 2010, so this project has been around a while? Never knew it existed, thanks for sharing! My *80 assembly skills are pretty novice (I've been spoiled by the 6809), but I'm studying OS design and this might make a fun project to dabble with. > > Anyway, for those interested there is a project to port CP/M to the > Model 100 w/ 64K all-RAM hardware.

[M100] Accelerators
I was just watching a review video of the old Apple IIGS, where he talked about getting a processor accelerator. I Remember the accelerators for the Amiga, even one for the C64. I wish there were a "turbo" board one could drop in on an M100, replacing the 80c85 with an 8088 (or low-power equivalent) at 4.77mhz and accompanying expansion ram. (imagining an M100 with 640k contiguous ram and relative addressing, and drooling...)
Re: [M100] Accelerators
didn't the bubble memory boards allow for contiguous memory? i recall reading that you could write and run a program beyond 32k using their booster pak like device. > Date: Mon, 1 Jun 2015 21:39:05 -0500 > From: hira...@hotmail.com > To: m100@lists.bitchin100.com > Subject: [M100] Accelerators > > I was just watching a review video of the old Apple IIGS, where he > talked about getting a processor accelerator.
