That was the first computer I ever coded on. You could fairly easily program it to make sounds. Having a cartridge slot definitely made it feel like a toy computer, but it set me on the path I'm still on today (programmer). Was a gift from my uncle...<br>

I miss the days of hooking your computer up to the spare TV.<br>

I find that statement confusing (maybe just me):<br>
"The SL-8 was based upon the TI 99/4 16 bit microcomputer and the SW development was done on the TMS 9900 development system."<br>
<br>
IMHO it’s the other way round, no?<br>
</blockquote>
<br>
When he says, "based upon the TI 99/4 16 bit microcomputer," I assume what he means is, "based upon the same MCU chip as used in the popular TI 99/4 product."<br>
<br>
I also assume that there was a real TMS 9900 development system available from Texas Instruments. At least I hope they didn't expect companies who designed around their chip to use a toy computer with a 40-column all-caps display. Besides, what do you think TI used when designing the TI 99/4 product itself? There must have been a commercial development system for the TMS 9900. God, I hope so.<br>

<br>
Hm ...<br>
<br>
"It ran on the development system until two days before NAMM when I suggested that we try running it on a 99/4 in the socket instead of the emulation environment. There were numerous issues, but it actually ran on the IC computer instead of the emulation system before we left for NAMM.”<br>
<br>
reading that it doesn’t get better: without thinking too much about it I’d have assumed some sort of ICE, but reading again … no …<br>
I did quick look-up on the net, no hints so far.<br>

<br>
I agree that the author is using confusing terms. We should give some leeway since this is a sales representative and not a technical person. I assume that the author is not Craig Anderton, who would presumably get the terminology right, even if just going from memory.<br>
<br>
That said, "emulation system" strongly implies that Texas Instruments offered something presumably more complex than the TI 99/4 toy computer for OEM use.<br>
<br>
We may never know. Let's just steal the ideas from the SL-8 and bump them up with modern capabilities!<br>
