Or simpler: You connect two 8-Bit latches (like 74LS574) to the 8085 address bus and the 574 clock to the CS of the circuit whose address you are looking for via an inverter (74LS04). And you read the address stored on the latch outputs with a voltmeter or you add LEDs. Or something more...

OK, I understand your problem better. You could connect a logic analyser to the 8085 and to the chip select (CS) of the ICs you're interested in. Then start up the 5322 and capture the addresses present on the bus each time a chip select of a peripheral is active. And to go further, once you...

The simplest thing would be to explain your project to us, and we might be able to give you some good advice. And a photo of the board might be useful. If you don't know the UART address (INTEL 8251?), there are 2 solutions: disassemble the code in ROM or use a logic analyzer. It's rare to...

This is good news. DM sent.

I also have his brother, the 468 :)

Hello Dave, I have a 465B (+DM44) to restore, so I'm interested in your manual service but I'm in France. Would shipping to France be possible, at my expense of course? Thanks, Marc

For me, this kind of project is only worthwhile if it's carried out using vintage components otherwise, you might as well switch to FPGA. Finding the necessary components is part of the challenge. I can recommend a seller who has 200 x MC26S10P at 0.9€ in stock or another who has 40 x MH8641 at...
