@mxb03523 Hello, i have tried the game but It can't start on emulator, neither on the real computer. Can you fix It please?
Thank you man 💓

@fabri600 It Is nice! Is It possibile ti have the listing?

🧠 Dare me to do it again.
Custom silicon. One teenager. Two ASICs. Zero fear.

In 1986, while still in college, I was asked by Myarc to design their first ASIC—an ambitious plan to shrink an entire TI-99/4A-compatible motherboard into a single 4000-gate chip. No roadmap. No YouTube. Just me, some gate arrays, and a mandate to bend logic to my will.

I trained directly with Mitsubishi’s EDA team, built the netlist, and verified the design with simulation vectors—all in under two weeks.

💥 First tape-out? Dead on arrival.
Not because of my logic—but because Mitsubishi’s own timing data was flawed.

I proved it, using custom boot ROMs, live oscilloscope traces, and hacked-together hardware mods. Mitsubishi acknowledged the issue, gave us a free second run, and I optimized the design even further.

✅ Second tape-out? Perfect.
Fully functional prototype. Demoed in Boston, Chicago, and Germany. Real-time TI-99/4A emulation in a compact form factor. First of its kind.

Fast-forward to 1987: Myarc wanted a second ASIC—this time for a unified Hard/Floppy Disk Controller. I spent six days on-site with California Devices, running nonstop validation.

🎯 First tape-out: flawless.

That chip went into mass production and became one of the most advanced I/O controllers in the TI-99/4A world. California Devices offered me a job on the spot.

⸻

Two ASICs. One tape-out failure I didn’t cause—but fixed. One flawless run.
And a lifetime’s worth of lessons in design integrity, systems thinking, and getting it right when it counts.

You want silicon that just works?
You want a first-time-right result under pressure?
You want someone who lives for the impossible?

Dare me to do it again.

I decided it's time for a #GaryOPA #Bluesky profile, since so many have recently left for other platforms. I will continue to support all social media places, but this way I can continue to stay in contact with all my #TI99 and Retro Technology supporters.

@FREEZE64UK Ah you mean Just for the se ADS... Ok so, no ti99 articles in It. Thanks anyway

[TI99 ItalianUserClub @ti99iuc]

@FREEZE64UK Where the ti99 Is mentioned in this Page please?
Thanks

[TI99 ItalianUserClub @ti99iuc]

@FREEZE64UK I can't see any ti994a article in this magazine, maybe you wrong to mention It?

[TI99 ItalianUserClub @ti99iuc]

@PartyHog64 Hey man, if you wand a quite complete pack for the TI99 in Mame I suggest to click on this link and scroll down until the download section. 😊
