IBM CP/M-86 v. 1.0 boot screen. Click image for larger view.
A working IBM-branded CP/M-86 version 1.0 OS disk has found it's way to me finally. These are not easy to find. By 1982 it was too late for Digital Research to secure a foothold as the operating system of choice for IBM's new 16-bit PC model 5150, six months after Microsoft's MS-DOS was already available. MS-DOS had more features and it was cheaper. I am not sure of the actual sales figures for IBM CP/M-86, but it can't be a high number. Original copies of this operating system are very hard to find today. For more information on the subject, read the July/August 1986 Micro/Systems Journal article titled ... [ read more ]

The original Apple ][ e computer.
Not much to say here, this is the original version of the Apple IIe, and this particular unit has a 64K card. I spent some time working through the 7 or so Apple IIe's I have, some need work. I'd like to get this one running with the Microsoft Softcard, so that I can run CP/M.

For those interested in S-100 Bus systems and corresponding CPM/MSDOS software, Andrew Lynch & I (John Monahan) have just finished constructing a new SVAG video prototype S-100 board. For those interesting in a better S-100 video display you might want to take a look at this board. It is capable of displaying a very crisp 100 characters per line. It is based on the LAVA-10 video chip set. This is a Xilinx Spartan 3 FPGA module. Please see here for more details:- http://s100...10%20Board.htm Enjoy">... [ read more ]

I wanted to see if I could do more than boot my MAX 80 using LDOS 5.1.3.
A Lobo Max 80 with a Lobo twin 8" drive, TRS 80 5Meg hard drive, and a set of Percom double density drives all attached to the back of the computer. The system is booting off the Percom drives using LDOS 5.1.3. Click image for larger image.
Close up of the drives.
Unfortunately my copy of CP/M for the MAX 80 won't boot on a single sided 8" Lobo drive. I need a 77 track DD drive, like a Shugart 850. I have no idea whether the TRS 80 5 mb hard drive actually works, but it made for a good picture.">... [ read more ]

For those that may be interested I have written up a detailed description and construction details of the new MSDOS Support S-100 bus Board that Andrew & I have completed. A while back we decided to try and put together a kind of "catch all" S-100 board that would cleanup some loose ends need to easily run MSDOS on an S-100 system and with our future CPU boards. Here is what we could fit on one S-100 board. Please go here for more information:- http://s1...DOS%20Board.htm In Summary the board contains:- 8259A PIC First of course we need an 8259A interrupt controller. The chip is hard wired to ports 20H and 21H -- ports almost ever PC 8259A in the world is hard wired to these ports! One very useful feature we found on one of our earlier PIC-RTC board was the LED bar that stretched any one of the eight S-100 bus interrup">... [ read more ]

Pictures. Status: System itself appears to work, in that I can load programs from the toggle switches and do some simple terminal I/O. There is an issue with the disk drive controller, but I will write more about that later. Looking for best way to use a laptop as a terminal to simulate a papertape for program I/O.

Updated: [ Personalizing CP/M2 24K on Northstar ] 03/18/2012
Been working for the past week and a half to build a set of hardware that I can install into any S-100 computer that will boot the Northstar Horizon DOS system. So far I have a working MDS-A3 card, disks, dual external drives, cable. I am working with various monitor programs to fit the DOS bootstrap at E800 into the system. Been experimenting with different approaches. A lot of work without much to show for it....yet I have also in parallel been trying to get *any* Micropolis disk drive to boot (FDOS). I have a Vector Graphic ZCB single board computer with something called the Northstar Monitor 1.5. Using this as the processor card I can then activate my DAJEN Prom card with DAJEN monitor program to burn ePROMS. The idea is that once I get a working system I can burn it into an ePROM(S). I have a serial switch box that I can use to jump to the differently-configured monit">... [ read more ]

A New 68000 CPU S-100 Board

by monahan_z
Total messages in this thread: 1
For those of you building S-100 bus systems and are following our work, I am delighted to announce that Andrew and I now have an S-100 bus Motorola 68000 CPU board that can be configured as an S-100 Bus Master or as a Bus Slave. In the second configuration the 68K CPU can sit silently in the bus (typically run by a Z80 master) and upon outputting a bit to a port take control completely from the z80 itself running the bus. This switching of CPUs can go back and forth continuously is as described in the IEEE-696 protocol. The board has room on board for a 32KX2 EEPROM pair and 32KX2 Static RAM. The 68K interrupt lines are active and up to 16MG or RAM can be utilized. A simple 68K Monitor is supplied. Further details can be found here:- http://s100compu...K%20CPU%20Board.htm We are taking limited orders for hobbyists that would like to t">... [ read more ]
