1. Could someone post some info on library and linkport programming or 
even better save me from the trouble of coding and send some sources 
for an I/O lib (possibly a standard serial protocol).
---------------------------------------------------------------------
2.0. I/O lib+ErrorDetectLib=MassStorageLib for Walkman (or other 
magnetic media). Would it be possible to just record bits (+5v = 1, 0v 
= 0 : or whatever the linkport voltage) to a tape recorder and read 
them back by playing the tape? I do miss those "Press play on tape" 
messages ...

2.1. Has anyone done any research on Sony Playstation memorycards and 
their suitability for a mass storage system for the TI85? The 
connector would be excellent for a "disk type" media. The data seems 
to be stored in blocks of 65536 bytes (16 blocks for a normal memory 
card -> 1 Mbyte). It can't be that complicated ...

2.2. I/O lib+h/w adapter=MIDI-TI85. (see my previous message)
---------------------------------------------------------------------
3. A dynamic memory allocation library has to be published or the 
Z80-asm scene can't evolve. If noone can work it out, we'll just have 
to ask Texas Instruments for it.
---------------------------------------------------------------------
4. Old games. It would be great if someone could find sources (c, 
pascal, any processor asm) for really old games (w/ ~<10k code?) f.ex 
Rogue, Hack, they shouldn't be too hard to port.
---------------------------------------------------------------------
5. Compilers. GCC, GPC, FPK-pascal - compilers w/ public sources ...

5.1. Can anyone get their hands on old Z80 compilers, say for the 
Spectrum Z80?
---------------------------------------------------------------------
6.0. Sounds. A 2 bit "soundcard" standard would be great, 1 bit is 
just a little too little.

6.1. Serial to parallel chip
- How complicated an 8 bit soundcard would be?
- How high a frequency would be possible for playback?
