Hello Roy, so good to see these lovely white ceramics eventually came to life again after been sticked in foam for almost 50 years. Eventhough the prom board will do a faster job and add basic, seeing the chips the way the readers could see it in the Electronics Australia magazine of May 1978 is kind of special. I wish you a lot of fun with it!
My first computer was the 2650. I had an Electronics Australia Baby 2650 System with an added S100 RAM board that had 11K of RAM comprising of 88 RAM chips. In a weak moment, I gave it all away, much to my sadness now. One addition was a 6847 (I think) memory mapped video I designed and wrote the code for. I still remember 3F 02 B4 was "Branch to Subroutine, Absolute, Unconditional, Character Out". All my code was entered in HEX via the serial terminal. I added an EPROM programmer, changed to a 3KBaud cassette interface and used a model 15 Teleprinter as my printer. Oh, memories!
@@dendad5128 I also had an EA 2650 kit when I was 15 years old but I could only afford 1K of RAM, I didn't have access to an assembler and I never really got my terminal to work properly. So it's been wonderful being able to revisit the 2650 again.
@@RoyAntaw My system was gained originally pre-built from a friend in the late 70s I think. I swapped an IBM Selectric Golf-ball terminal for it. Then I extensively modified it. Somewhere in my shed I still have FORTH for the 2650. Many years ago I purchased that but the order got lost so by the time it was found and sent to me, the 2650 had been replaced with a Rabble Ozi (Ohio Scientific clone made here in Oz) 6502 system, so I never got to try it out. I did have a great collection of early machines and in the giveaway, they went too, much to my sorrow now.

Fantastic serial cable shenanigans!
Very cool! I look forward to seeing what else you do with it.

Hello
Having a 2650 processor, I recreated this project
What is the communication protocol ? I can't decipher what comes out on the Flag pin
Thank you
What is the mini-board?
