oki, both appear to be playable.
For the Zodiac Output PLA, see: http://git.redump.net/mame/tree/src/mame/drivers/hh_tms1k.cpp#n794

Cool! I was trying to figure out the 20 terms in the PLA, but I guess it doesn't matter as long as we know the 32 outputs. It looks like they had to get pretty creative to fit all their symbols and LED signals in there. I promise I'm not a believer in astrology, it's just that there are several astrology/biorhythm devices from that time period!

It's interesting that the manual shows the letter "G" in "GO" like the number 6 but without the center g segment, but that's not one of the outputs. Maybe their prototype had that, but they couldn't fit it into the O PLA?

I've been trying to get my O PLA dumper to dump the 2 halves of the PLA in one session, but I mostly get the half with the status latch clear. I have to power off and wait a while to get it to dump the half with the status latch set. I'm executing a YNEA opcode to set/clear the status latch before TDO, but it doesn't matter; I get the same 16 bytes in both halves everytime. It might be because I have to assert reset to set the PC to the opcode I want to execute, then release it to run the opcode. I'm also keeping R10 high all the time; maybe I need to drive it low when I'm not dumping the ROM.

I uploaded info on Conic Football II:

I also posted a couple of scans of Lost Treasure:

Yeah, I think astrology stuff is bs, but I won't put that opinion of mine in MAME source code. When it comes to preservation of these old handhelds, every little piece is a part of history. =)

The Zodiac manual also shows "i" as 2 segments(like the "1" digit). This YouTube video says otherwise: https://www.youtube.com/watch?v=-AEU7jXo-pY
Plus: the 12 leds wouldn't work properly in that case.

Conic Football II appears to be playable. There may be missing 'graphics' due to the 2nd half of the output PLA being unknown but I didn't see anything obvious missing.

I dumped it many times and only got those 16 values, so I figured that's all they defined. It has all the 7-segment codes as well as the lower 4 individual bits.

I've made a bunch of changes recently to my code, so I'll try to dump it again and see if anything else shows up.

I'm trying to suss out TP0450, can't find much official documentation for it. US4361873 describes this chip but not in as much detail as for example the TI30 patent. The only certain thing I have for now is the microinstruction lanes, done by carefully tracing the lines and comparing them with TMS0980.

Rotate die photo so ROM is at lower-left, RAM is at upper-left. Microinstructions OR lanes left-to-right are:

NE
C8
_YTP
_NDMTP
_DMTP
_MTP
_CKP
AUTY
AUTA
_15TN
_CKN
_MTN
_NATN
_ATN
CKM
SSS
_CIN
STO
CME
SSE

Nice! So many calcs and educational toys used those chips it seems like there would be some info somewhere. Let me know if you need some higher-resolution pics.

I uploaded info on Coleco Head to Head Basketball: http://www.seanriddle.com/cop400.html

I see in hh_tms1k.cpp that there is also a TMS1000 version.

The lilprof82 big die photos are good for me. On quick glance(exclude rombits), TI55 dice are the same as that one. You have the CMOS Business ANalyst too right? If it's TP320 instead of TP450, I'm interested in a large die photo for that.
