Mystry Singal Board Computer Burroughs SD280 & Mainframe Card

[TheEPROM9]

Unknown Single Board Computer by Simon Lyne, on Flickr

It is unknown what this computer board came from, what OS it ran or its pourpus Datecodes on the chip date it at 1980 to 1981, rans a 8086 CPU, full 16-bit goodnes. Have not been able to figure out any more by reading the ROM's. If anyone knows anything about the system this thing is from then please share. I have had it for years, makes a nice display pice to go with my retro computers.

Number on the under side of the PCB is AW 28895795 REV D

Mainframe Card by Simon Lyne, on Flickr

The mainframe card. What you see is what you get. A complete unknown what machine it is fro& the function it preformed as none of the chip part numbers seem to have datasheets anymore.

Feel free to post your unknown computer cards you have & maybe we can get some answers. =-)

Whatever it is, that's an impressive slab of EPROMs.

How about this one? Weirdly the RIFA smoke caps are still in perfect condition on this board.

It looks like something out of a telecoms rack

Edit. the SICK board is something to do with automation/sensing

On the first board, I see a 'B' logo just to the right of the lower DIP switches that makes me think it's from Burroughs.  What it's used for, I have no idea.

[TheEPROM9]

Power relay goodnes. Not sure if it would be out of telecoms kit or an old mainframe PSU.

You know i have neve notest that B logo, might be a good indicator to go off.

I have reached out to the retro computer comunity, arcade compunity & no one knows what system it is out of. The seller said it had a 1MB of RAM but looking at the chips that seems way to high.

Good call, The middle board (light green) looks to be the same construction type as a Burroughs B series

[TheEPROM9]

Agreed, so far my only link. Still trying to find what machine it is from.

I don't think it is because if you look at it you can see all the races are rightangels & the squire patten on the bottom left look to be the logo of the company that made it, however there is litraly nothing to go on with this board as not even the compnents show up online.

[TheEPROM9]

I have made a ROM dump of the six EPROM's. I was not able to get anything out of the msk ROM's, if you can help with this please do.

i'd say it's a serial interface card for something


files EPROM64_4.BIN and EPROM64_5.BIN are split, once merged you get a load of text strings that relate to serial protocol, printers etc (see below)

EPROM64_3 and 2 also look like they are split, but just seems to be program code

EPROM32_1 seems to have some text in at the end, but again it's split and i don't see the other half in the other files, so you are missing 1/2, maybe in the other 2 eproms you couldn't read?

Nice, I did not think to do that with the ROM chips, that for the first time actualy unearths some real info about what it did.

The two mask ROM's covers my the yellow stickers markings are B Logo 8130 751 2890 1411 BRASIL & B Logo 8206 500 2890 1387 BRASIL, these are both custom Burroughs ROM's

I am not sure how one would go about reading these so I am still foxed there. Intresting to see sripped EPROM's for the first time, but then I am use to devices having 1 or 2 of them at max.

I have not been able to find anything on the interwebs about these chips, capasity or anything. I am not even sure of the are 64K like the larger EPROM's on the board. At this point I am more hunting around the internet trying to find people who know more about Burroughs machines & thus might know more about it.

It could esily be related to being a serial card or that was how the user would interact with the machine via serial terminal & thus you are seeing the UI part of the OS. There is something about monitoir mode in there. I still need to look though the HEX dump in detail as I have only just skim read it.

Thanks for doing that though =-)

I'm wondering if this is the CPU board out of a teletype terminal made by them.

The phrase "circuit 111/126" lead me here: http://www.bitsavers.org/pdf/burroughs/terminal/

i bet they are just one time programmable, so a EPROM without the window. They might read out if you dropped them into your eprom reader as a M2764 like the other 28 pin ones

in all though yea this does look like it's part of one of those terminals

[TheEPROM9]

Good news, I was able to read the Mask ROM's, Pin 1 on my programmer gave me an error  So I bridged it with the 5V pin 28. That sorted the error as it did not need the high voltage for reading & I won't be programming these things.

When I had it set to 2764 the reads that did not error just came up blank, so I incresed it upto 27512, I was plesently suprised to see data on the last 64K of the chip, so I went with 27128. I do not know if these are actualy 128K chips or they just have a diffrent starting address. Anyway I was able to sucessfuly extract the data from the two chips. 

I have attached them in their own zip file & also a image showing what file names relate to waht chips, the EPROM's are just numbered but I think you already worked out where the go on the board, now it is confirmed.

Hopfly this will allow you to do your magic & pice together the rest of the code, might just unvail some more mystrys.

Also thanks for helping with this. Could be from those terminals, have not been able to confirm it yet, but they are long documents.

I will tell you what, this EPROM programer was well worth the 50 quid it cost.

It is a async/sync serial port controller board for a Burroughs mainframe.

ROM 4+5 goes together as 16 bit, probably for the 8086, and they contain the strings of the configuration interface.

Notice that there are also a 8041 on the board near the top, it has an internal ROM.

This kind of very over-engineered design was a major reason why that entire line of mainframes were uncompetitive and (mostly) died out.

[amyk]

Looking at the picture and the ROM images it's obvious now that 0 and MROM128_0 form a pair, MROM128_1 and 1 another pair, as well as 2 and 3, 4 and 5.

[TheEPROM9]

Anyone know how to combine the ROMs, everything I have tryed has just resulted in crap outputs. 
I know there is the whole thing to do with odd & even ROM's & that is probaly what is tripping me up.

[dexters_lab]

IIRC WinHex can do it but isn't free

i have some command line utils for interleaving eprom files, it only works on WinXP though  I really should find something newer!

i was going to convert the last files you uploaded but i've been a bit busy making videos!

Here is a C program that will merge binary files. Specify the source files followed by the output file.

Code: [Select]

// bin_merge.cpp : Interleaved merge of binary files

#include <stdio.h>
#include <stdint.h>

int main(int argc, const char* argv[])
{
if (argc < 3) return -1;

int const step = argc - 2;
printf("%i files to merge\n", step);

Might have to try & run this on linux, Windows is being Windows.
