A New 8086 CPU Board, Monitor, CPM86

Total messages in this thread: 1
Well after 3 months of work and 3 prototype S-100 boards later (thanks Andrew!) I think we finally have an 8086 S-100 board we really like. It runs at 8MHz (two IO wait states) on the S100 bus and appears to be very reliable. Realizing that moving from a Z80 to an 8086 system is difficult for many people I wrote a very extensive 8086 monitor to help you get going. I have written up a fairly detailed step by step process to help people get going. (When the production boards come I will of course add the step by step construction notes). Also I have written up a complete section explaining how to build a CPM86+ operating system with only an CPM(80) system working. All necessary files are included. Here are the pages:- http://s100comp...itor/8086%20Monitor.htm... [ read more ]

A Propeller Driven S100 Console-IO Board

Last Post: [ S100 Console-IO Board ] 05/27/2011
Andrew and I have now finished our Propeller driven S-100 Console-IO board. This board allows you to utilize a standard IBM-PC keyboard for Console input and outputs a standard VGA signal (e.g. for a modern LCD display). There are a number of port and status bit jumpers that should allow the board to be transparently spliced into most old S-100 systems without any software changes. While the hardware for the board is done, there is ample room for a good Propeller "Spin" programmer to improve upon the software to increase the boards current 80X24 resolution. Please see here for more information:- http://s1...IO%20Board.htm Enjoy... [ read more ]

I bought a foot of 3/8" OD 1/4" ID plastic tubing from the hardware store and inserted over the print hammer head (with the old rubber pad removed). Seems to work great...any comments? Anyone done this see any long-term damage? UPDATE: I received a message that Wayne Durkee's "official" word on the replacement of the rubber head is to use 7/16 OD - 5/16 ID vinyl tubing. Cut 7/8 inch long.... [ read more ]

Lambda Physik TRS 80

Last Post: [ Lambda Physik FL 580 ] 03/30/2011
The Lambda Physik FL 580 Scan Control device used a TRS 80 Model 1 as it's computer. And it's orange.
The Lambda Physik unit powers up and responds to front panel toggle switches. The scan control unit was attached to the TRS 80 Model 1 via the expansion port. The card cage system would likely have been accessed by running a SYSTEM command from the TRS 80 and then at the asterisk prompt a command like /nnnnn where nnnnn = the memory location (?) of the scan control unit. I tried /12345 but it did not activate the unit. This is the memory location of the stringy floppy. Preliminary testing reveals a bad TRS 80 power supply, but when a working supply was used the computer was able to boot up. The computer has 16K. model 26-1006. Also attached to the TRS 80 is a set of... [ read more ]

Just FYI, I have written up a step by step set of instructions for installing CPM3 on a floppy disk system. The current writeup is for a very simple "Non-Banked" system. I will later enlarge upon this for a "Banked" system and for a more extensive IDE drive hard disk system. See:- http://s100comp...3%20BIOS%20Software.htm... [ read more ]
