I suspect it's 5" 40trk flp

try varx https://www.ebay.com/itm/326103335571 just sold

I've dumped the firmware from the board I bought, and got a scan of the manual which includes the schematics of the personality boards http://bitsavers.org/pdf/intercontinentalMicroSystems/ICM_CPZ-186/ I suspect the prom is for a 5" drive (CPZ-186_40T on the label) Are there other firmware...

http://www.jrfmagnetics.com/tapeheadintro.html NOS 1/2" 9-track tape heads are still available. I've bought many, many, many of them. 7-track has been out of production for 50 years and are very difficult to find combo 7/9 track heads are even less common

You need it to isolate the sense amps from adjacent board digital logic noise, which you can deal with by rearranging the cards.

I've never had to do this, but it came up in another context. Can emulated images be written back to a physical drive with the emulator board?

I got confused between this and the old messaging system. I do like the new arrangement.

Thanks! that would be helpful. The CPZ-186 has an on-board floppy controller. http://www.s100computers.com/Hardware%20Folder/IMS/80186%20SBC/80186.htm I've had a pile of other boards for a while, I need to go back and see if I have a hard disk controller Do you have any idea what this is...

I've had a few 80186 slave boards for a while, and just picked up an ICM CPZ-186 SBC. I was wondering if the TurboDOS for it has turned up. I didn't see a thread about 16 bit TurboDOS beyond the one about getting it running on a PC.

I think the last time I needed power connectors I just watched on ebay for them someone on eBay is selling complete bus cable assys https://www.ebay.com/itm/266774813263

If anyone still has a 5218 I'd really like to document the logic inside of it with good pictures of the board innards and if there is any firmware to dump.
