I am always looking for more technical info on the TI-99/4A and its peripherals. If you happen to know something that you think would fit in these pages, please let me know. In particular, I am looking for:
- Data manual for the TMS9919 sound chip
- Data manual for GROM memory chips
- Schematics and/or programming info for any peripheral not described
in
these pages (Gram kracker, etc)
- Info on special hardware (e.g. mouse, keyboard, MBE voice control
system,
etc)
Finally, if you can provide an answer to any of the following question, your contribution would be appreciated:
Drive controller:
- Why is there a +12V buffer on the disk controller card, to send
the
selection signals back to cru bits?
- Anyone knows a program that
scans
an assembly source and adds comments indicating how long each
instruction
is going to take for execution?
- Does XML >14 place the string length in
word >8350-51 for string array elements?
