Purchased a PPEB

I just purchased an 8M PPEB with case and the activity led installed. Has a preloaded microsd card included.

A "8MB PPEB" for the TI-99/4A refers to a modern, compact, all-in-one expansion device built around a Raspberry Pi Pico W, designed to emulate the massive, original 1980s Peripheral Expansion Box (PEB). "PPEB" stands for [Pi Pico[W] Peripheral Expansion Box].



It is designed to fit in a small case. Mine in a 3D-printed enclosure or sometimes a repurposed original speech synthesizer case and plugs directly into the TI-99/4A's side expansion port, rather than needing a large external unit.

Key Features and Capabilities:
- 8MB RAM Expansion: This specifically provides massive memory expansion, often utilizing SAMS (software-activated memory system) memory management to support 1MB or 8MB configurations, far exceeding the original 32K limit.  There are configurations that support 16MB.

- Virtual Disk Storage: The device emulates floppy drives and hard drives using a MicroSD card or the Pico's internal storage, allowing you to run games and software without physical disk drives.
Sidecar Form Factor: It replaces the massive, 30 lb original PEB box and its many expansion cards with one small module that sits on the side of the computer.

- Modern Connectivity: It often provides USB or Wi-Fi capabilities for file transfers.

New hardware project - my computer desk

I have 5 to 7 computers on my desk at any given time. With literal, physical desktop space being sparse, I have decided to do something that I think most would find odd. I'm going to take my Atari and my C64 and put them in a tower.


I will need a mechanism that will allow the two boards to share a single keyboard and a way to possibly power each independently.


I'll leave my primary Tandy CoCo2 and TI-99/4A alone of course.

I also need a tape cassette cable for the Tandy Coco so I can backup and restore code to my file server. 

WAR IRON of the Red Clan

I'm going to do something I have never tried before, to make a game in Tandy's SG24 mode.  This will be a major difference in the development path I'm taking with the TI-99/4A, C64, and Atari 8-bit.  Those three system's graphics are being done with 8x8 bitmap pixels.
