nanoPEB arrived

Today my nanoPEB finally arrived. Looks so cool and futuristic. The nanoPEB is an unofficial hardware expansion. I got mine from Jaime Malilong, I don't know yet if he is building this piece of hardware himself.

A nanoPEB is basically a nano (size) Peripherical Expansion Box for the TI-99/4A. It is hookep up on the side of the console, also called Sideport (Speech Synthesizer, Flex Cable,..)


It features a 32kb Memory Expansion, a serial RS-232 interface, an emulated disc controller with 3 emulated disk drives. You can store your disk image collection on the compact flash card, and mount a disk image very easy to the disk drive of your choice.


The wonderful part about all this: every part of it a 100% compatible replacement for the original hardware.

After 15 long years I am proud to tell that I own a TI-99/4A again! It really is in awesome shape. I got to try it out immediately after work.





Still missing are the other orders: the nanoPEB, the Speech Synthesizer, several Cartridges, a WICO Atari Joystick Adapter and I even found someone to sell me an original Texas Instruments brownvinyl dust cover.

Welcome to my TI-99/4A Blog!

This is my first post.


My name is Klaus and I live in Vienna in Austria.


When I was around 3 years old, it must have been the year 1983, my father bought a brand new TI-99/4A for our home with just a bunch of cartridges, a tape recorder and a pair of joysticks.


Until 1994, the TI-99 was the only computer for our home. The collection grew and grew.


Books, Magazines, Expansion Box, Memory Expansion, Disk Drives, Cartridge Collection, the Big Disk Program Collection. My mother used to call the Expansion Box “Mikrowelle” because it looked like one to her.


My brother and I were really interested in it, and programmed a lot in Extended Basic. Programming Assembler was simply too much for us, due to lack in propably both, english knowledge and technical skills.


In the year 1994 we demanded a IBM Personal Computer, an Intel 486, the TI-99 had to make room for his successor. We regret this step greatly, because it is all gone now.


In 2009 my brother, his little son and I attended the International TI-99/4A and Geneve User Meeting in Vienna for a few hours. What can we say? All three of us got in love with the real system again! Emulation is simply not the same. The other attendees were so kind and donated us a basic setup, a TI-99/4A with a pair of Joysticks and Speech Synthesizer. One of the members of germany even promised to send us some gaming cartridges.


Of course I wanted a Texas Instruments as well, and as time went bye, the demand got higher and higher. On the 17th october 2010 I bought one on ebay. It looks like brand new on the photos, it’s a black PAL model. Now I am waiting for the console to arrive.


I bought a Compact Flash Drive/RS232 Port (CF7+) as well, now called nanoPEB, via ebay! This item has not arrived yet.


Can’t wait to play with this stuff!
