    Just a 'simple' Assembler for CP/M 3.....

    Cool. Well, I'm making the final tweaks to the serial card in my S-100 so I can start testing some real software downloads. Up to this point it has mainly been test code stuff like repeatedly sending the same code to the port to make sure it shows up correctly on the other end, an end to end...

    Just a 'simple' Assembler for CP/M 3.....

    David, I will absolutely check that out. Wow, I didn't know I had a part to play. Thanks. I will grab the ASM.BAS file and see how QB64 works with it. Other than the native BASIC languages that are native to CP/M, QB64 is my goto for PC based work.

    Just a 'simple' Assembler for CP/M 3.....

    Okay Chuck, Doug, and the rest of y'all; you have me figured out..... Looks like I'll be 'edumicating' myself on that collection of assemblers. But, I do actually have a copy of ZASMB amongst all the FoxHollow, Walnut Creek, etc stuff I have downloaded. I really should catalog that stuff...

    Just a 'simple' Assembler for CP/M 3.....

    Well, I had figured that might be the case. Odd that in all these years, there was never just something simple that was ever written for this. I suspect possibly due to a memory size limitation maybe. I do have both M-80 & L-80 combined in an .LBR file, but I'm not sure how to extract them into...

    Just a 'simple' Assembler for CP/M 3.....

    Soon, I shall be making the leap from 2.2 to 3.0, and as I go through the various docs I have downloaded, I'm trying to find a simple, native Z-80, assembler, that I can run in a CP/M 3 environment. I see the MAC and RMAC, but I'm just looking for something that I can write some Z-80 (not 8080)...

    CP/M 2.2 vs 3.0

    Well, my STD machine will stay at 2.2 and I'm hoping the S-100 can be 3.0. We shall see.

    CP/M 2.2 vs 3.0

    Well, my first project, that I now just write code for from time to time, is an STD bus Z-80 @ 2MHz running CP/M 2.2. You all have helped me many times figure things out. My new project is an S-100 bus system with boards from S100computers.com which has the ability to run CP/M 3. So; why...

    CP/M 2.2 vs 3.0

    I'm sure there are many of you that have put together a system using the S100computers.com boards, and I am now in those ranks as well. My current Z-80 STD bus system is running CP/M 2.2, but my new S-100 Z-80 system is going to run CP/M 3.0. I'm just wondering if anyone has a list of some of...

    (Almost) every record holder for the world's smallest mechanical hard drive in one photo

    The milspec variant of the 62PC went into the BYH-1 Submarine Random Access Storage Set (SUBRASS) and the milspec version of the 3340 went into the UYH-2 Disk Memory Set (DMS). I wish I had pictures of those to post. Lost to time.....

    (Almost) every record holder for the world's smallest mechanical hard drive in one photo

    The IBM 62PC also had a military version that was used in the IBM submarine sonar & combat control systems that I used to work on. And then there is the 'Starship Enterprise' IBM 3340 removable hard drive. They were nicknamed that because of how they looked...

    S-100 slot connectors

    Digi-Key has 925 of them in stock as of my posting this (https://www.digikey.com/en/products/detail/edac-inc/346-100-520-202/107833?s=N4IgTCBcDaIKIBEDCBmALANgIwAYwFoA5BEAXQF8g). Please leave 3 of them for me to buy in a few days.... :)

    Chicken vs. Egg - getting files on a CP/M machine

    I think for this go round, given that this system is kinda like a kit, I'm going to go for broke and put CP/M 3 on it.. But to the question of getting some of my code for the stuff I need, I think I have figured a plan out by doing something akin to the 'boot loader' approach to get the serial...

    Chicken vs. Egg - getting files on a CP/M machine

    Well, it does, to a point. I have used that tool to create the first disk using Image #4. That said, the tool relies on an .imgc files for a source. And after a bit more noodling around, it appears that the tool is capable of creating a CP/M compatible CF card image....... Hmmm. That seems too...

    Chicken vs. Egg - getting files on a CP/M machine

    Yep, it is the S100computers stuff; Z80 Master, dual IDE/CF board, and RAM, and the Prop Console card. But they don't have a serial interface to download code. So I was thinking I could take one the the CF cards, pop it into my PC and copy the loose CP/M files I have to it, pop the CF card back...

    Chicken vs. Egg - getting files on a CP/M machine

    I'm putting together an S-100 CP/M machine that consists of a CPU board, a memory board, a dual CF disk storage board, and a keyboard, mouse, and display board. There is no disk controller card,and the CPU Monitor program is setup to use a serial interface that I do not have. I got to thinking...
