@@circuitvalley Central Electronic Complex, also called the Central Processing Complex - a name for the general-purpose hardware running a mainframe system (so basically the actual computers and not things like JBODs or networking). Reading some listings, I think this card was made for DS8870 which went EoSL in 2020 (so no more support from IBM; it stopped being sold or receiving updates in 2016) which is probably why it can be found this cheap.
This is pretty cool, thanks. Will you be working on simple stack that will allow a PC to communicate with the FPGA over the PCI bus ? That would be awesome.
When you JTAG in and program the FPGA, you're not storing that onto the tiny 8-pin configuration memory, I'm guessing? Are there any pins like the JTAG pins that would let you rewrite the config memory?
Almost always Config Memory is programmed using FPGA itself a Bridge Between JTAG and Flash. All programs Vivado, Lattice, Intel . First load a small program to FPGA to provide access to Flash and then Program flash over same JTAG. You don't need Direct connection to Flash memory.
I am a nub at FPGA and analog stuff but I do know computers, but I am confused at why this would be a good idea? I found some dev boards with the same FPGA chip for 50 bucks. Is this board alot more powerful?
nice board but it is not really cheap, i noted cost over 60 bucks on ebay. I wonder how it is possible to find out the correct pins for the uart receivers. Just pointing with the probes around the TX anf the BGA??
@@circuitvalley Ah. It's been years since I've used either brand, but was not impressed with Quartus, and not really with X's pre-Viv toolsuite. Viv did look promising.
Excellent video! I appreciate you left some of the dead ends (like probing the JTAG pins) as it really helps troubleshoot when things go wrong.
Thank you
This is a very underrated channel! Loving your content
I appreciate that!
Really cool idea using a fpga configuration outputting the pin number on each pin… have to remember this one!
This kind of video makes the day brighter.
Thank you for your Kind words.
IBM 98Y2610 - CEC enclosure RS-485 serial interface card
Thank you for pointing it out, Do you happen to know what is a CEC?

@@oplik0 That is some different world terminology. Thank you for your time and efforts.
always an impressive video from you
Thank you.
Trans receiver??? Is that a receiver that identifies as a transmitter? I think you meant transceiver. In all seriousness, nice video :)
Thank you.

Yes There is a Design Example Available from Intel, Source Binary are already available in my Github Repo.
@@circuitvalley Great! Thank you. I will check it out,
Nice work!
Thank you! Cheers!
Great work

Good job, thx for sharing,
Thanks for watching!
Just checked on ebay and they all crazy expensive
Price shot up after Video, There were few sites other than ebay selling for around 30 EURbut now they are all out of stock.
Hackaday effect, everyone jumped on it and the sellers jacked up the price.
If you just open Quartus 2, create a project, select this fpga as your target, and then open the pin planner, you might get some Info?
Yeah that is also one even better way to do it. Thank you for your comment and Time.

@@CallistoPili Yes thats what he did, just used the scope...
@@exithe I love the idea to launch for every pin a serial packet with the pin number.!!!!
I am glad you liked it.
Why do u prefer xilinx?
Xilinx has better tool "Vivado" Has better documentation. Better support. Better community Support as well.
