Note from  This entire site is thanks to Ernie Pergrem, a former member of the Chicago TI User's Group.  This is written from his perspective.

I would be remiss if I failed to acknowledge the two people who influenced the creation of the TI-99/4A Home Computer Book Archive project; Marc Hull and David Haynes.

In January, 2011 I was working with Marc on SID Play 99.  To assist in my understanding of how the Sound Interface Device (SID) worked, he directed me to  After viewing the site, it occurred to me that the 100+ books that I had gathering dust might be a great start to something similar for the 99/4(A).

I sent a list of questions to the email link on Bombjack, asking what equipment and software had been used to create the files and not sure if I would receive a response.  Within an hour, my inbox contained a reply from David with the answers.  When it came time to construct the home page, I once again contacted David and he graciously allowed me to borrow from his, even offering to link to my site.

Whether you are a Commodore user or not, take a moment to visit  It's time on the Internet well spent.  After that, scurry on over to YouTube and view some of Marc's SID on the 99/4A videos.  If you find yourself interested in becoming the owner of a SID Master 99 (all the best people are..), then you can order one from The Destroyer's TI99/4A Page.


Although I have a substantial number of TI-99/4(A) english language books, I don't have them all.  I would like to thank the following TIers for helping me fill any gaps.

Visitors can access a list of other titles that I am seeking by clicking the In search of... link on the main page.


In 2013 I added three new sections to the archive.  The Miscellaneous section is for publications that user groups or individuals created to generate revenue for the group treasury or themselves.  The remaining sections; Assembly Language and LOGO focus on specific languages.  However, in the case of Compute!'s Beginner's Guide to Assembly Language on the TI-99/4A I have chosen to leave the language specific book with the publisher's other titles.

After having the binding removed, the book pages are scanned on a Fujitsu SnapScan S1500 sheet-fed scanner as 300-400dpi, black & white, searchable PDF files.  Covers are scanned using a Epson Perfection 4990 Photo flat-bed scanner at 200dpi, 24-bit color.  Although this results in a larger file, it allows for improved clarity and print quality.  Besides, a 2TB hard drive can be had for less than $100USD and the days of dial-up Internet access are 99.9% behind us.

Software used to create the PC99 and V9T9 disk images include the PC99 Read Sector/Write Sector utilities, TIImageTool, Ti99Dir, QMC2, and MESS.  Where required, TEXTLOADER was used to convert the source code in text format to executable files.

This site was done as a personal project with the afterthought that others might find it useful.  It came as some surprise that named it their October, 2011 "TI99/4A website of the month" and the following month it received the Rob Tempelmans Plat Award at the 2011 Chicago TI Faire.  My thanks go to TI-Gebruikersgroep Nederland and Chicago TI Users Group as well as my fellow TIers who were tasked with choosing the recipient for the RTPA and to retroclouds on AtariAge.
