Case Study - Restoring an Intel MDS-225 Case Study - Restoring an Intel MDS-225 Introduction This is the story of my work to get an Intel MDS-225 up and running under ISIS-II on 8-inch FDDs. This machine consists of two multibus boards: MDS-225 IPC and ZX-200A DSDD FDC. I got the MDS-225 board from Richard Main who was also designer of the Zendex ZX-200A. This has been updated with hardware and software changes as I make them. I have been doing battle with this system and software for several months. The constant changes represent findings and fixes I have done along the way. The Hardware Reference Manual (HRM) for the Intel MDS-225 I have is Intel Order Number. The Schematic Diagrams for the Intel MDS-225 I have is Intel Order Number. The Hardware Interface Manual for the Intel MDS-225 I have is Intel Order Number. 18 wheels of steel american long haul completo tpb.

The ISIS-II User's Guide I have is Intel Order Number. Try One To do this I initially had: 1) A known good MDS-225 IPC board with jumpers set for ZX-200A. 2) An unknown Zendex ZX-200A (Equivalent of the iSBC 202). 3) An new ATX Power Supply. Doro 225 Ipc Software Review![]() 4) My homebrew MDS-225 Adapter (MDS-225 P2 Adapter). 5) Bootable 8-inch ISIS-II, Ver 4.3, M2FM media. 6) 8-inch floppy disk drives. 7) The manuals listed above. 8) MDS-225 Monitor Version 1.3 EPROM on the MDS-225. 9) An unknown MDS-22X/23X Card Cage. I spent several months messing with this board set and the 8-inch drives. I had one disk from Richard that would ocassionally boot. But not reliably. And the other disks did not boot at all. It was frustrating, to say the least! It turns out the problem was with the priority bus request not being implimented. I found this out after I switched to 3.5-inch FDDs. During the time I was messing with the 8-inch drives, Richard had developed an adapter board that drove 4 each 3.5-inch drives at 360 RPM (1.6MB) that emualted exactly the 8-inch double density M2FM drives on the original MDS-225. He had created bootable disks that worked with this system. He was able to copy between 8- and 3.5-inch DD media. Also during this time, Richard had designed an MDS-225 P2 Adapter which would replaced my homebrew adaptor. This made the conversion of the MDS-IPC cleaner than it was before. He sells these adapters on his site,. One thing I noticed on the new ATX power supply label was that the 3.3V, 5V and 12V supplies required a minimum load (see picture of ATX PS above). The system will load the 5V supply correctly, but the 3.3V supply is not used so a resistor load must be provided for it. I may use an SATA drive to load the 12V supply for initial tests. I had not noticed this requirement on the older ATX power supplies. The minimum load has been with us for a long time. The standard says it is required to maintain regulation. So bear this in mind. In these old systems the 3.3V is not used and has no load. Also, the MDS-225 requires a source of -10V used to create -5V for the onboard RAM. I do not have -5V or -10V on the new ATX power supply so I used the -12V to supply this need. -5V used to be common on older ATX power supplies. Standard 24-pin ATX Power Connector.

The P2 adapter mounts on the end of the cable and provides the connections to the two serial connectors (10-pin headers) and for parallel priority (10-pin header). I connected the RS-232 lines off the P2 adapter to two DE-9/DB-25 RS-232 connectors I pulled from old PC serial boards. The original IOC board provided some jumpers to reverse or loopback the TXD/RXD and CTS/RTS pairs. Old PC DB-25 to 10-pin Header.
