PC Board Identification
Posted by rakownz@reddit | vintagecomputing | View on Reddit | 38 comments
Hi there, does anybody know what type of board this is? Google image and the numbers on it don't seem to pull up anything. I know the processor is an AMD AM29030 but other than that I can't identify anything about it.

Damn that thing is CLEAN.
molniya@reddit
I know, right? I wonder if it was a spare that never actually got used.
start_run_cmd@reddit
It’s a board from a Fire monitoring/alarm system.
Cwc2413@reddit
Why do you say that? There seems to be far too much logic onboard for that.
festivus4restof@reddit
High rise?
Cwc2413@reddit
Maybe. Seems that would be much more I/O than anything but maybe.
LitPixel@reddit
Cool find nonetheless
VimtoUK@reddit
I just did a search for JRL Systems for you and the first thing it did was link me straight back to this post. Thanks, Google.

Hahah ya same here, never heard of them before and thought they may have just been the producer of the blank PCB.
algaefied_creek@reddit
Look at all those chips! Holy moly it’s a smorgusbord going on there!
Is this the board for said JRL LP 180 16 HighRes Laser Printer/Plotter?!
Page 42 of KeySolutions January 1994 has a JRL Plotter
God I used to love working with the engineers when I was a kid at my dad’s employment location. I wanted to actually be a plotter when I was a kid. Like be the printer.
Anyway.

This is awesome thanks so much!
Apprehensive-Page899@reddit
Based on the 29030 and the JRL silkscreen, I'm guessing a printer control board. Either an internal board for a postscript printer or a RIP
pchernik@reddit
For clarity, "PC" also means "printed circuit" (as in PCB = printed circuit board). So there's nothing wrong with asking "what PC (i.e. printed circuit) board is this?". However, folks are accurate that it doesn't look anything like a PC (as in Personal Computer) board.

Printed Circuit Board has its OWN acronym. PCB.
bio4m@reddit
Its not from a PC.
Its some kind of industrial board
i_design_computers@reddit
PC Board is short for Printed Circuit Board not Personal Computer. This is definitely a PCB.
festivus4restof@reddit
Ummmm NO.
RFC793@reddit
PCB is short for Printed Circuit Board. A PC Board is a board for a Personal Computer.
WingedGundark@reddit
It has nothing to do with PCs, it is from some industrial/embedded application. AMD chip is a 32-bit RISC microcontroller/cpu and it has few Altera CPLDs.

WingedGundark@reddit
Why shorten partly, and not like you also did and is the usual way: PCB?
songoffall@reddit
This is not a PC board. Likely some industrial automation device. Lots of CLPDs and an AMD RISC processor.
RepresentativeCut486@reddit
FPGAs Chipset, as hardcore custom as it gets.
hougaard@reddit
First thing to do is to dump the ROMs, which will probably answer most questions.
Educational_Bee_6245@reddit
Dosen't like a PC Board. It's probably for some specialized embedded system, considering all those Altera chips which are probably FPGAs. Also AM29030 is not a PC Processor but a RISC Processor.

24megabits@reddit
I have seen people refer to PCBs as "PC boards" in the past, but replying to three different comments with the exact same thing isn't going to make people more likely to listen to you.
WingedGundark@reddit
Those Altera chips definitely aren’t FPGAs, but CPLDs. Programmable yes, but much simpler compared to FPGAs. They are used as replacement for glue logic or asic chips, but they can’t be used as microcontrollers or cpus.
You can often find several CPLDs on these boards, unlike FPGAs.
Educational_Bee_6245@reddit
Yes, was too lazy to look those chips up.
molniya@reddit
It looks like this is a RIP (raster image processor) for a high-end electrostatic plotter or printer, and not a PC at all. First off, as you noted, the CPU is an Am29000, used in embedded systems but not related to or compatible with x86. If you look at the connector labels, there’s a floppy interface, but also a “Greensheet I/F” which was for connecting to Versatec-compatible plotters etc., and a “bi-tronics” interface that sounds like a bidirectional parallel interface from a similar niche. Lots of Altera CPLDs that are consistent with custom hardware interfaces, too. So this would have been the printer side that a computer would have sent a PostScript print job to; it would render the PostScript to a raster image and sent that to the actual printing device. Where did you find this thing?

Thanks for all the info this was at an estate sale in southern PA near Shrewsbury I bought a whole box of boards and PC parts and the previous owner had lots of old software and computer programming books as well.

Hello there from Spring Grove.
rakownz@reddit (OP)
Thanks everyone for all the suggestions and information I will list it on eBay as I really don't want to tear this up if it is indeed a rare item that someone would love to have or tinker with.
Laser_Krypton7000@reddit
Sell it on ebay
I found the following:
"likely pertains to the manufacturer of medical, scientific, or bioelectrical impedance analyzers (specifically the BIA 103) originally based in Detroit, Michigan"
Plaidomatic@reddit
This looks like a development board for the AMD29030 CPU. The combination of programmable devices everywhere and connectors for logic probes suggests that this is to help engineers build role-specific hardware around the 29030.
Please don’t destroy this board, it seems to be quite unique. Find a collector or museum who will take appropriate care of it.

Pcb indicates the now defunct manufacturer: JRL Systems, Inc. Graphics device controllers, graphics data translators, graphics printers, and network solutions. JRL Systems was sold to Network Technology, PLC in January 1997.

So best use for this would probably be to salvage the chips and scrap the PCB?
rakownz@reddit (OP)
Thanks! Ya that totally makes sense it had none of the standard motherboard qualities like an input panel for power cord, mouse or keyboard.
