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 ]

Last Post: [ 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

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 ]

Xerox 8010 Star

Last Post: [ Xerox Star 8010 ] 02/27/2012
The XEROX model 8010 was known as the Xerox Star because that was the name of its application software. Before the Apple Lisa and Apple Macintosh, the "Star" is generally accepted to be the first stand-alone commercial computer to employ the graphical user interface / desktop metaphor. This particular system is missing the side panels, wheels, and is not fully operational. The notes to follow describe what steps have been taken to stabilize and hopefully restore this system. Aside from the ugliness of the exposed steel under carriage, the only real problem that I have detected so far is the Quantum Q 2040's drive belt, and possibly some bad RAM.
