    I had a great time getting this one ready for the buyer, too! I'm very glad it got there in one piece -- CRT televisions are tricky to ship! Glad I haven't lost my touch. :)

    Great!! Each item was individually wrapped, packed well and shipped quickly. Everything as-described and it all works perfectly! We are having fun trying to answer trivia questions from the 80's (LOL)! Excellent seller!

    Absolutely thrilled with this purchase! I've been searching for the VIC-1011A RS-232C Interface Cartridge for quite some time, and finding it through The Nostalgia Nexus was a dream come true. The item arrived exactly as described—clean, well-packaged. I can tell this seller really cares about preserving vintage tech and delivering a great eBay experience. Shipping was fast. Highly recommended for any retro computing enthusiast! Call them, They aint afraid of no ghosts!

    That's right! And if you buy my original copy of Ghosts and Goblins on cartridge, I can prove it, too! Absolutely perfect buyer, no issues whatsoever! Hope to do business again!

    Vintage product in good working order. This Peripheral Expansion Box was a necessity for anyone who wanted to expand the Ti99/4A computer back in the day. They are very rugged but don’t last forever. Holds the memory expansion, RS232 interface (serial and parallel), disk controller and floppy disk drives, etc. Recently, people have been building and selling modern upgrades that fit in the PEB. Example: the TIPI (which uses a Raspberry Pi to provide a virtual disk drive system and allows the TI to function as a WiFi enabled computer). The 110v fan sounds like a jet taking off and the thing weighs a ton. Gotta love it.
