these are Z80 CPU/SIO boards from the early 80s I got them from a book and record store I worked at long ago check out the hand wiring
That’s a loooot of chips!
A $1 chip is now more powerful than all these chips. Makes me think what will happen in 30 years. I am happy I was born at a perfect tech stage. I got to see b&w tvs, got to see landline getting installed at home, got to hold the monster heavy first cell and car cell …
Can you port NETMF on it?
Surely we are in nice world of technology where we are not required to discover but to enhance our ability. Technology has now become small but with better results…
I am glad to see that I am not the only one that hand wires to solve issues after pcb production
Get to see the first computer you worked on used as the command console of a space ship in a grade c science fiction movie…
Get to enter a program into vacuum tube computer by punching each bit into a punch card one by one…
Reminds me of the times when I started with microprocessors in 1976 on a SC/MP 1MHz processor, to be programmed in machine language. Persistent storage was an audio tape coupled with an acoustic coupler, printer was a LO 15 teletype.
Maaaan I still work on stuff that looks pretty similar to that Z80 board. This product is actually controlled by a 386 and DOS 6.22… but the look is similar. And as far as the airline support equipment industry goes it’s not at all that uncommon.
This was from a system Called Byron custom made book and record store management system If I recall correctly these boards had I/O ports connected to a MUX that connect the dumb terminals and line printers to the main system we had at one point around 200 connections to 9 stores and a warehouse all gone now as no one buys records or books anymore. It was a great place to work and when they went under we had a closing party and I snagged these and the Neon sign. The Store was Olsson’s Books and Records in Washington DC

6510… weeks for creating just 1 screen and handling the inputs, compare this to now… i loved the hard way… but then again… today is slightly more productive, no?
