8282    - The Monitor program on 256TC crashes the system. This appears
8383      to be a MAME core bug involving the z80pio.
8484
85    - The 256TC corrupts itself when a floppy disk is detected.
86
8587    - Disk system doesn't work because of fdc problems.
8688
8789    - Teleterm: keyboard is problematic, and cursor doesn't show.

94    Description of Disk System
95
96    - Ports 44 to 47 are for standard connection to FD2793.
97    - Port 48 is used for drive/side/density select on write,
98              and intrq/drq on read.
99      intrq and drq are OR'd together, then gated to bit 7 of the
100      data bus whenever port 48 is activated on read. There are
101      no interrupts used in the disk system.
102
103      Despite the simplicity of this design, disks have not worked
104      in the emulator for some years. Conversion to the new modern
105      implementation (2013-07-05) has not resolved the issue.
106
107      There are 3 types of microbee disks available in the wild.
108
109    - CPCEMU-format "dsk" disks, which has an already-working
110      format "dsk_dsk".
111
112    - ubee512-format disks, such as "ds80,ds82,ds84,ss80", etc.
113      These are described in "mbee_dsk", but it's not known if it
114      works as yet.
115
116    - There a "img" format for the 128k boot disk. The internal
117      layout is not known and no work has been done.
