Side question...did old ISA based systems support dual video cards? I'm trying to test the VGA card in an old IBM PS/1 to make sure it at least works but it doesn't display anything when installed. It doesn't cause any errors either tho.

>>61772045
Yes, got one which is the secondary testing I am working on. Problem is the EGA card has a 37 pin port to which a dongle attached. I sourced possible solution but so far no joy

>>61772044
Yes.

I hope you didn't get jewed out of a lot of shekels.

>>61772143
What? I see the normal EGA port back there. I seriously hope you're not confusing the LPT port for EGA.

>>61772044
Can you use a VL Bus card in a regular ISA slot like that?

>>61771946
Jannies and mods are retarded, they only ban cryptobeggers and CP. Youre safe

>>61771946
EGA is compatible with VGA, I don't recall which way though. I think you can connect a VGA monitor to an EGA card (unless I have it backwards; wait for another reply to be sure). I do remember having done it as a kid and it worked fine (I wish I remembered which way I did it though)

>>61772442
I'd really like to know too. could it be why OP is getting beeps?

That's some retarded shit son. VGA is analog and uses a 15-pin connector. EGA is TTL and uses a 9-pin connector.

I know once upon a time I did so so yes.

This is the EGA card in question...

It is an ETB Four-on-the-Floor. Note the 37 pin port.

>>61772724
Errr STB not ETB sorry.

>>61772654
this was over 20 years ago. maybe it was an EGA monitor plugged into a CGA card? I really don't remember anymore

>>61772874
>EGA monitor plugged into a CGA card?
Yes.

>>61772887
no I think CGA and EGA were incompatible despite the same DB-9 connector

I may have used one of these

Nope. EGA could drive CGA monitors.

Ain't gonna work buddy. First as I said, EGA is TTL, second it's totally different frequencies, like 15kHz over VGAs 31kHz.

You would need a EGA/VGA card that has both connectors on the back.

Also, EGA could also drive a MDA monitor with the right switch settings that most cards had, same for CGA driving MDA monitors.

>>61772972
do people really take everything that's on sale online as a fact?

>>61771946
Looks like it would make a good Steam box

>>61772654
Not him, but I vaguely recall a friend having a pin converter. It may have been to plug a VGA monitor into an EGA card, it may have been to plug an EGA monitor into a VGA card, I dunno. And doing some quick research, the two standards do have a couple of video modes in common.

Things like >>61772045 exist for a reason you know.

>>61773125
It could be that the specific monitor he had was built to handle both signals and the pin adapter came with it and would be useless with anything else.

>>61771946
If you are lucky, there might be a jumper or a dip switch on the motherboard that sets it up for use with a VGA card. If it does not have such a thing, you need to buy an EGA to VGA converter or an old monitor.

Well no joy thus far. I tried to dig through my cables to find a compatible serial cable that I could wire up to the EGA-VGA converter but oddly I don't have one that I can find in my piles of cables.

EGA/VGA share the same "mode" configuration

>>61774928
lol no. EEPROMs need ALOT more to wipe em. That said I am curious how they've held up over the years. The card has been enclosed in the system so it hasn't been hit my much UV light, but age also is a factor. Of course I also have used much older exposed EEPROMs with no issue.

>>61774928
Only if xenon.

>>61774865
Wack. Could it be a custom ring-network card or, dare I say it, uplink/downlink of some sort?

>>61774989
If this stuff is flight-rated, we'd be seeing SN54 parts instead of SN74.

>>61774989
This thing isn't going to space. Never was. It's ground equipment.
The windows of the chips weren't covered.

>>61775010
Nope. I regularly use my phone flash to clear them. True, once will only garbage it, but that's enough to make it useless for him or anyone.

Having them exposed in a inside room without direct light isn't as much as a problem, that's how that card got there anyway, (if) he used a LED flash that produce way more UV than normal LEDs just close up by them. I'm not certain about camera flashers.

>>61775036
uh...no

Not op, but you made me remember when a friend made the same mistake back in the day, One of the roms was bricked and the other just stuttered for a while

A prototype might have been built with wire-wrap before this was built. As you unwrap the prototype, you can write each connection down on a netlist, which the tech building the "production" copies uses.

>>61775154
So it's a Display System Computer Input Multiplexer. These cards were some kind of video inputs, like multiplexers for CCTV systems.

>>61775283
OK explain more. Serious. Think in terms of the shuttle in simulation how would it be used?

>>61775299
Probably exactly the same way as a cctv system. It takes video feeds in on these cards and the machine on the whole can do whatever the user wants with the feeds (like adding annotations) before spitting it back out on some monitors.

>>61775323
OK that might make some sense considering the EGA card which dumps video to 4 monitors.

I'm thinking that this system might be an input/output for the shuttle displays in simulation.

>>61775361
It certainly looks something like that. Date stamps on the hardware read 1992/1993 so off the shelf cctv multiplex equipment was certainly commonly available at the time. Whatever processing they were doing with the video feeds was probably a little more complicated than standard cctv fare judging by the custom work.

>>61775283
The two inductors/transformers and the two 1MHz async serial Manchester adapters (D1-6408-9) http://www.intersil.com/content/dam/Intersil/documents/hd-6/hd-6408.pdf (and the 12MHz oscillator to generate x12 clock to drive them at top speed) seem to suggest deep space communications or some other more custom protocol.
I wonder what type numbers are under the label on the 40-pin IC.

This is what you cunts get for not buying AMD.

>>61775576
No...Diversified was owned by Ergon but ceased in 2013 (3 years after my first enquiry). The STB card on the other hand falls under nvidia but they haven't responses to my questions.

https://en.wikipedia.org/wiki/Diversified_Technology,_Inc.

Diversified Technologies looks like they just built the chassis and main board. I doubt beyond that they had direct communication with NASA as those are generic parts from what I see.
