Nah, it doesn't halt properly. I fixed it for the 186 and 286 but forget the 8086.

Edit: but that's not actually the problem, oops.

btw, support for output to tape is missing in ibm5150, mc1502 and other clones which have cassette port. I've added it just now to mc1502 (works fine), will check others too.

Thanks. Does DOS actually boot for you? The `sfdos' from softlist doesn't ('Disk boot failure').

It does but I have to patch wd_fdc.c by commenting out line 119 (seek_start(RESTORE)). Curt and OG seem to be sure the line is correct though.

Well, Curt and/or OG need to be sent a copy of the dos and asked what's up. Robbbert got pretty good results doing that smile

http://www.sendspace.com/file/kyboqh -- softlist just in case

https://gist.github.com/shattered/6628920 -- mc1502 WIP (cassette output, printer WIP, serial WIP, minor keyboard fix)

BTW, PC drivers used to support .dsk image format but not anymore, any reason for that?

The patch doesn't apply cleanly in drivers/pc.c. There's a stray "#if 0" in there.

... and the actual reason why mc1502 did not boot is: reset pin is active low.
