Osborne 1 SS/DD 40 Track 204.8kbyte Profile - Help

[ldkraemer]

David, Will you please add a profile for Osborne 1 40 Track SS/DD 204,800 Byte image.

CPM Definitions are:

BEGIN OSB2 Osborne 1 - SSDD 48 tpi 5.25" - 1024 x 5 DENSITY MFM LOW CYLINDERS 40 SIDES 1 SECTORS 5 1024 SIDE1 0 1,2,3,4,5 BSH 3 BLM 7 EXM 0 DSM 184 DRM 63 AL0 0C0H AL1 0 OFS 3 END

##libdsk Definition [osb2] description = OSB2 Osborne 1 = SSDD 48 tpi 5.25" = 1024 x 5 cylinders = 40 heads = 1 secsize = 1024 sectors = 5 secbase = 1 datarate = DD

##Flashfloppy/GOTEK Definition [osb2] cyls = 40 heads = 1 secs = 5 interleave = 1 bps = 1024 id = 1 #rpm = 360 rpm = 300 rate = 250 mode = mfm iam = no

I've created a rough draft for OSB2_525.textpb and attached a 204800 byte image (Sector Dump) that should write correctly.

I won't be able to boot it, but I can access it with my Kaypro II, TRS-80 Model 4, and Ampro Little Board.

Thanks.

Larry
