Wanted: MITS/Pertec Extended BASIC

Hello all, In the continuing saga of my Icom Attache, I have it up and running, no magic smoke, and I have received the manual from Steve Shepard (THANKS!). However, with only 512 bytes of EPROM on the Turnkey board (TURMON and MBL 1702s), it's a bit limited :-) The monitor can display memory, alter memory, or jump to a memory location. The MBL can load from a cassette tape. That's about it... The manual did note that there are a few versions of BASIC that this machine can run. 8K BASIC is the smallest, and also the most limited. More interesting to me is what they referred to as "Extended BASIC" either on cassette tape, or on a PROM board. Further up the line is DEBI (Disk Extended Basic by Icom), but I have no spare floppy controller for this machine. If anyone has Intel HEX files for the Extended BASIC EPROMs, or Extended BASIC on cassette tape, please let me know... Thanks!! Rich B.
