TTi Thurlby LA3200 logic analyser service manual and disassembler EPROMs TA2000

[rh100605]

Hi
I have posted the service manual for the LA3200 / LA4800 logic analyser with circuit diagrams for both analyser and AP01/2/3/4 pods on http://www.ko4bb.com/manuals/index.php?dir=06)_Misc_Test_Equipment  and use the search Thurlby Thandar

I have added pod diagrams for the TA1000 / TA2000 logic analysers as well and have the Eproms for these models.

I have also uploaded the EPROM Images for the Z80 and DP6502 disassembler pods on the same site. This EPROM will work in most AP01/ AP02 pods if the logic and sockets are fitted. otherwise you will have to use the circuit diagrams in the service manual to install some TTL and a socket.

If anyone has other disassembler EPROM images I would be very interested in sharing. (e.g. 6800 / 6502 68HC11 )
I have  reverse engineered the Z80 and 6502 versions...… and made 6800 /11 8051 and 6303 versions.

Many thanks!

Realise I'm replying to a 10 year old thread here but I'm looking for additional info (Manuals) and disassembler ROM's for the TA1000 Logic analyser.
I have 8085 and 6502 ROMS in the machine at the moment and would love a copy of the Z80 ROM.

Documentation for this model seems scarce too - a service manual would be wonderful

Thanks

I have found the assembler source for the TA2000 to disassemble z80 - Z180 code.
I made this by disassembling the 8085 disassembler I had and modifying it for the Z80/181.
I did the 6303 and 68000 as well. I debugged these by using an LA4800 logic analyser to debug the Z80 and used the TA2000 serial port to load the analyser with examples of every op code. I could then watch the TA2000 disassembly on the LA4800.

Attached is assembler file and the listing in a zip file.
I have built the bin(obj) file using the Telemark Assembler as described in the .asm header but any Z80 assembler should work.

As 16 mbit roms are difficult to find, I used 32 or 64mbit roms with the same code image reproduced 2 or 4 times to allow all forms of unused address bits being tied up/down.

There maybe another solution I have a LA4800  and Z80 disassembler roms but the pods I have now do not accept a rom which is sensed and loaded  at power up. This could be a small "vero board add on.... circuits in the service manual on KO4BB.com ( link in earlier post)
