I added a driver for the COP400 handhelds, see: http://git.redump.net/mame/tree/src/mess/drivers/hh_cop400.c

Lightfight is fully playable. Entex Space Invader and Mattel Funtronics Jacks are responsive and do some stuff right, but are very buggy overall.

I think the MCU emulation core is not perfect yet. I did fix some small bugs there(eg. Space Invader didn't boot at all at first), but I don't know enough of COP400 (yet) though to see where the problems are.

COP400 is definitely buggy; I ran into a lot of problems trying to hook it up properly to the Lisa driver.

Definitely very little info online besides that book. There's two pages in "Microprocessor Data Book" (S. A. Money)
https://books.google.com/books?id=e0SoBQ...ge&q=MM78LA

One page in "Microprocessor and Microcomputer Data Digest": https://books.google.com/books?id=WxUjAAAAMAAJ&q=MM78LA&dq=MM78LA

and one table in a page in this issue of Electronic Design: https://books.google.com/books?id=KuAEAQAAIAAJ&q=MM78LA&dq=MM78LA

You can get a few more summaries this way: https://www.google.com/search?q=%22MM78LA%22&num=100&safe=off&tbm=bks

And these guys digging around in 2004: http://ana-3.lcs.mit.edu/~jnc/cctalk/2004-July/1584.html

But that's all that's leaping out at me... </masteroftheobvious>

Thanks! I hit that first link for every chip I look up! I also had found that last link, but the Microprocessor and Microcomputer Data Digest looks interesting. Luckily AbeBooks had it for $3.50 shipped, so I ordered one. It's probably similar to the Microprocessor Data Book, but maybe there's another hint or two.

Cool! I'm confident of all 3 of those dumps, since I did them electronically and compared hundreds (thousands even) of dumps of each chip. But there are probably a few bits wrong in Plus One since I dumped it visually. I'm going to clean the die in nitric acid and take more pics. Funtronics Red Light Green Light is on the way, and I bet it uses a COP410L, too.

When I used unidasm on the Entex Space Invader code, it didn't work quite right because the COP444L has a 2K address space. There might be other little differences between the 3 different COP chips used in those games.

I have Gravity listed as:

Invented by: Tim Effler
Programmed by: Peter Oliphant
I don't think Lesser was involved on that one.

Cool! I didn't realize anyone else programmed those Rockwell chips. Peter Oliphant sounds interesting- from child actor to game designer, including credits on Defender of the Crown and Rocket Ranger.

Poking through some more odd stuff... Found some interesting things:
Coleco Quiz Wiz Challenger:
http://www.handheldmuseum.com/Z_Imgs/MESS/Coleco_QuizWizChallenger_CPU.jpg
TMS1000, but socketed for our convenience... smile
Milton Bradley Arcade Mania (board game with an electronic device) :
http://www.handheldmuseum.com/Z_Imgs/MESS/MB_ArcadeMania_CPU.jpg
TI M34078A-N2LL
Mattel Computer Backgammon (LCD game)
http://www.handheldmuseum.com/Z_Imgs/MESS/Mattel_ComputerBackgammon_CPU.jpg
Just labeled T6753 1777-9339 (Toshiba I assume...)
Mattel Diet Trac (an LCD weight-loss calculator basically...)
http://www.handheldmuseum.com/Z_Imgs/MESS/Mattel_DietTrac_CPU.jpg
Toshiba T6768

I found these interesting:
Mattel Horse Race Analyzer:
http://www.handheldmuseum.com/Z_Imgs/MESS/Mattel_HorseRaceAnalyzer_CPU.jpg
TMS1100 with an LCD driver chip (looks like a Hughes chip)
This was sold by Mattel for a while, and when they stopped selling it, the inventors bought it back from them and sold it under their own name: AHTI
Their version looks like the same on the outside, but this is the board in it:
http://www.handheldmuseum.com/Z_Imgs/MESS/AHTI_HorseRaceAnalyzer_CPU.jpg
HD613901-B62
Obviously completely redesigned... Mattel's version came out in 1979 or so, the AHTI came out around 1994, so I assume that had a lot to do with it... I was just surprised to see it so radically different...

Don't know what's dumpable of all that, but thought I'd share...

I didn't try unidasm with the COP400 myself, but I can see it supports COP410,20,and 44 so in theory it should work.

Entex Turtles and Stargate work fine on MESS, added them this morning. These games have the Hitachi MCU, and a COP411L for handling sound. (oh, still need to add the gamespeed knob on Stargate)

Rik-
I've been looking at Quiz Wiz Challengers on ebay. I decapped the chip in Quiz Wiz, and it's not a microcontroller, just some logic that scrambles the question number using the cartridge (which is just some traces on a PCB). I guess they programmed that logic into the TMS along with the extra features.

Unfortunately, the TMSs in your pics are E and G revisions, so not currently completely dumpable. But seeing what's inside helps. Datasheetarchive has several Hughes LCD controllers, but I didn't see 0530.
