Default Re: New SC/MP II system

>Bonjour
I will try a reply to your question
My kit is from 1976 and the problem was to find the asr33. finally get it four time the cost of the kit, but with the three 'grey' technical manuals
Assembling was not a problem as i use ttl and new cmos circuit
But....quite a long moment to understand how connect the kit to the tty
By chance, no error, and everything goes nice at the first power on
In reality it was,this time a very long moment before the PTR1 (or 2)do as i expect...learn the 'fantasy' of the 'status registef' ....and so on
After near an half century...no regret...programming in 'machine code' step by step is the best way...before assembly and others exotic langage
With only 256 octets of ram the things were rapidly 'short'...so with two more pairs of 2112 ram i can go from 0500 to 07FF...with some 'naval battle' or a 'mastermind' which use a lotde paper on the tty.je
I will try to post a pair of pictures
