I have a lot of them but this one is my favorite.
The picture shows the development system for the 80C31 Intel microcontroller.
Some parts are missing but the memory of my beginnings remains.

Now we are talking (ancient) history :-DD

I do have some of that era too. Two of the boards are own development experimental prototypes for smart card reading writing, two are also own development sensor to midi processing boards of which one is a four layer board. Very expensive at the time. The other two are (industrial) control boards. One is 65SC02 based and the other is a Philips 80C552 micro-controller based board.

Does anyone like to buy development boards like me?

I've got well over a hundred dev boards from over a dozen companies, so yes, I like to buy them too.

OK folks - what the most "obscure" development board that you have in your "collection."
I think in my case it is the VersaKit-3074, for one of the early FRAM-based 8051 chips from Ramtron (who were acquired by TI, IIRC.)  Although the Zilog EZ8 board might be close.  No - wait!  I apparently have a National COP8 board!
(these are dangerous times for board hoarders, with vendors offering "under $30" (2020 dollars!) development boards as a matter of course, as opposed to "under $100" (1990 dollars) "specials.")

I have a few oddballs around here, most antiques such as a RTC/EVM7000N-1 (a TMS7000 Evaluation Module) and an Advanced CMOS Logic System Evaluation Board - a kit to test fan out and propagation delay of several 244 and 373 latches from various manufacturers.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

That is an oddball MCU that was used in the Siel Opera 6 synthesizer of which I own one. :) Still in good nick. Wrote an emulator for it many years back.

Not so much obscure but definitely ancient, I have this MC6800 system - A heathkit ET-3400.

In a way it's a shame the 6800 has disappeared. It's probably by far the easier of the 1970s 8 bit micros to learn the entire instruction set of, and very orthogonal. It's just not very efficient, in either code size or speed, compared to the much more complex to understand 6502 and 8080/z80.

For me it’s a KIM-1 from MOS Technology that I acquired back in 1977.

I also have this illness, https://lab.2help.win/.

I hope this isn't contagious

Don't feel too guilty.

I might have, too, about 20 boards or so, anything from $2 Arduino nano to SDR or FPGA boards.  Anyway, I'm afraid the abundance of cheap devboards we used to see before 2020 might never come back, so we might be "the last generation of shoemakers".  ;D

There's a broken one on ebay for the usual silly price.

The really cheap is in the past for sure with the added shipping and VAT. The cheapest bluepill I bought was Euro 1,32 and the cheapest Arduino Micro (Nano without the USB -> Serial) was Euro 1,27. Now you pay that at least for shipping alone :palm:
