Thanks to strepto for making this disk image available. A standard Microbee DS80 3.5" disk auto-booting with no copy protection.
This system was initially derived from ZCMD29, a ZCPR2 modified version with special features for RCPM use. Updated by Tony Ellis in 1987 and suitable for 128k Microbees. Further updated by P B Hutchison in Nov 1989 to include SH, FAST & SLOW for further Microbee compatibility. This beta version 0.6 was compiled in 1991. There is PBHCCP05.MAC (and HEX) on the disk and the ASM file for CONFIG is also included but no .COM version. Bootup looks like -
This version is for a Microbee 256TC ONLY that has also had its memory upgraded to 512k and a WD1002-5 Hard Drive controller attached. The HDFORMAT program (by PBH in 1990) is for a Seagate ST-225 (20mb) with 615 cylinders, 4 heads and 17 sectors/track with a sector size of 512 bytes. So not suitable for many 256TC's, but the source code may be able to be converted to run on a normal 256TC or even a 128k Microbee.
So in the MbeeTech Repository in the Microbee\Software\System_Disks folder we placed
pbh_bios_v0.6_system_ds80.dsk
