Bootstrap REXCPM

bootstrap_rexcpm.txt

Run-through for reference, old but mostly still the same:

Part 1 - REXCPM firmware and option roms
https://youtu.be/tb0WYQCaF1I

Part 2 - CPM disk image
https://youtu.be/M-rBnPiVQOE


=== One-time prerequisite ===
(linux/bsd/mac, for windows works in msys2 or cygwin but not wsl)

git clone https://github.com/bkw777/dlplus.git
cd dlplus
make clean all && sudo make install


=== To start ===
Connect a proper usb-serial adapter and serial cable
http://tandy.wiki/Model_T_Serial_Cable

Download the REXCPM zip, option roms, and M100_CPM files from
http://bitchin100.com/wiki/index.php?title=REXCPM
and
http://bitchin100.com/wiki/index.php?title=M100_CP/M
(don't need CPM.CO, just CPMUPD.CO and CPMn10.BK)

cd into the dir with the downloaded and files, and run:
 unzip REX*.ZIP
 unzip M100*.zip
 dl -vb ./rxcini.DO ;dl -v

( for Windows if you don't want to use cygwin or msys2 to compile & run dl2,
  ".\tsend.ps1 -file rxcini.DO" in place of "dl -vb rxcini.DO"
  ".\LaddieAlpha.EXE COM5 6" in place of "dl -v"
  https://github.com/bkw777/tsend
  https://bitchin100.com/wiki/index.php?title=LaddieCon#LaddieAlpha
)

Leave that running through all remaining steps.
