Yep. Letting one of my rare things go.

I got this in the mail Friday--it is exactly as described and a great little bit of rare TI hardware. I know of less than half a dozen survivors of this little box, and he has another one up now with a different software configuration. These were the first GROM simulator boxes TI made, followed by the GSIM and EGROM boxes. The GSIM (also known as the Pizza Box) was the only one that put the code in RAM. The GSIM is the most common of the three, as I've seen more than a dozen of those turn up for sale over the years.
