Welcome to the nanoPEB and CF7+ Website!

The nanoPEBs and the CF7+ were designed to bring the full experience of the TI-99/4a home computer into the 21st century and yet be affordable. This site offers the support programs and manuals needed to run either. As time progresses, articles and a FAQ will be added to help get the most out of both.

nanoPEB (Version 1)

nanoPEB Version 1 uses the TMS9902 UART for traditional performance. It provides an RS-232 port named "RS232".

Features:

CPU RAM - 32K - Fully compatible with Extended BASIC and Editor/Assembler
Emulates of three floppy drives - DSK1, DSK2 and DSK3
Comes with a Compact Flash - Compact Flash is preloaded with CFMGR.
Virtual 400kb diskettes (called "volumes")  Original 99/4a diskette was only 90kb!
Serial Port "RS232" - uses standard DB-9 cables (needs null modem cable to connect to PC). Baud rate up to 9600.
Built-in BASIC commands  lets you format and mount volumes into the emulated disk drives.
Sample OPEN command in BASIC: -
OPEN #1:"RS232.BA=9600.DA=8.PA=N.EC"

nanoPEB (Version 2)

nanoPEB Version 2 uses the 16C550 UART for higher performance. It provides an RS-232 port named "COM1" which replaces the PIO port found in CF7+.

Features:

CPU RAM - 32K - Fully compatible with Extended BASIC and Editor/Assembler
Emulates of three floppy drives - DSK1, DSK2 and DSK3
Comes with a Compact Flash - Compact Flash is preloaded with CFMGR.
Virtual 400kb diskettes (called "volumes")  Original 99/4a diskette was only 90kb!
Serial Port "COM1"/"RS232" - uses standard DB-9 cables (needs null modem cable to connect to PC). Baud rate up to 115200!
Built-in BASIC commands  lets you format and mount volumes into the emulated disk drives.
Sample OPEN command in BASIC: -
OPEN #1:"RS232.BA=115200.DA=8.PA=N.EC"
OPEN #1:"COM1.BA=115200.DA=8.PA=N.EC"
New! Compatible version of Fred Kaal's CFHDXS1
