Eeh you wos lucky, we had 't toggle boot strap in't PDP 11/05 in Octal on front panel to even get Assembler!
I kid you not. Digital PDP 11/05 with Teletype. On power up, I used to load a bootstrap program of about 20 instructions with switches (0 or 1) on the front panel, so it would read a machine code loader (this was a 16 bit m/c and the code was written as a series of Octal lines, 1 per instruction, on a crib card). Then you could run the machine code, via another short instruction, so it would recognise the TT. Then you could load the BASAC (yes not BASIC, but a Solatron version called BASAC) interpreter written in Assembler into the CPU. After that, you were cooking on gas, could load ASCII tapes of programs etc. When was this?
