I got a handful of these chips at my job when they were being thrown away. They are Programmable Logic Devices. I found a datasheet online from 1997 that says that xilinx bought the ip for a similar chip, but the website is dataman.com and I don't know if it is a reliable source, and the information is 20 years old.

I've done a little bit of hobby fpga programming with verilog and I wonder how similar this procedure is, if it is similar at all.

I've found atmel, academic, wikipedia, hackaday, and instructablestutorials but they are all about either chips that come on a board with some sort of serial port or else they are circuit diagrams and I think they expect someone with a different education than mine to take the next step.

update: found one two three videos on youtube and skimming them shows some talk about the circuit diagrams. Ill come back if I find an answer and maybe answer this question myself.

    \$\begingroup\$ I admire your inquisitive mind Julian but they were a struggle to design more than basic circuits for. I can't help you on getting them programmed but I can encourage you to jump forward into CPLDs and FPGAs and put your good learning into something you can use again and again. Good luck with wherever it takes you :-) \$\endgroup\$

  • \$\begingroup\$ The 22V10 is a PLD ...just like a CPLD in most respects, it's just not very dense (fewer cells). These are mainly obsolete now, but if you picked up a lifetime supply you can use something like Xilinx ISE to program them, or still available from multiple sources is WinCUPL (atmel.com/tools/WINCUPL.aspx ... ee-classes.usc.edu/ee459/library/documents/CUPL_Reference.pdf). There are plenty of CPLD/FPGA programmers that still support them \$\endgroup\$ Commented Jun 4, 2017 at 0:36

IIRC DataMan were a manufacturer of quite respectable EPROM/PLD/PAL/GAL/CPLD programming hardware back then, In fact there may still be an old Dataman S3 kicking around the office.

I would however strongly second Tonys suggestion to learn on something more modern, it will be far more useful.

  • \$\begingroup\$ sounds like good advice. Learning these old technologies can take as much time as learning a new technology but it doesn't have the same payoff I guess \$\endgroup\$ Commented Jun 4, 2017 at 1:42
