So I have been very lacy at updating this README file.You need to retain copyright notices in the source code.
#Ti 99 4a bios code#
The source code is made available under the LGPL license terms. At least for now (without contributors from others) My TI-99/4A clone implemented with a TMS99105 CPU and FPGA (master branch).Īnother version of the clone (the latest development in soft-cpu branch) includes my own File names are not important, but must end in.The Disk, TIPI and PCode DSR/Roms are optional, but required if you want to use the related feature.While the Myarc-FDC-80Track DSR (crc32 7BF4862B) provides access to 3.5" Floppy Images. The Myarc-FDC DSR (crc32 042968A9) (found in MAME) provides 40 Track SSSD/DSSD/SSDD/DSDD, The standard TI-FDC DSR provides 40 Track SSSD/DSSD Floppy Support.The System Grom (994AGROM.BIN) and the System Rom (994aROM.BIN) are required at a minimum.Īlternate Grom/Roms (ex 994AGrom-QI.BIN) can also be used.The Roms/Groms/DSRs specified in the Hardware submenu persist through reboots.These roms are no longer bundled with each cartridge rom and now must be specified in the Hardware submenu.Instructions to modify the code to get a RPI Zero W working with MiSter will be in the tipi_rpi_zero.md file.Tipi on Raspberry PI Zero W via the USER IO can be flaky and may require code modification to get it working which beyond this README file.If you will use a breakout board, it MUST be a USB 3.1 Breakout board with 10 pins.Other board's noted pin #s may not match. USB Breakout Board model B01MRK0REP used for reference.
