Hi guys,

I have a few things that I can't identify, but I have some pictures of them. If you have any clue, please post :)


1. 8bit ISA - apparently graphics adapter / LPT controller combo - all that I found written on the PCB is "MGP" and "Y-10" - nothing else. Well, the serial number, but that's kinda useless - it has two connectors: DB9 and DB25, both female. AMD chip is an AM9128-15PC [via Google I found that to be some kind of static RAM, but that doesn't tell me much] - the other 2 large ones are some UMC-built controllers, I guess for the DB25 port [LPT] photo (http://89.136.157.229/vintage/Parts/Card/Graphics/Unknown%20MGP%20Y-10%20-%208bit%20ISA.jpg)

2. 16bit ISA - Some kind of "computer-on-a-card" with an Intel 486DX4 100MHz, 72pin SIMMs, etc... Nothing useful written on the card, I've searched everything and nothing conclusive. Photo (http://89.136.157.229/vintage/Parts/Card/Weird/Unknown%20PC-On-Card%20-%20Intel%20486%20DX4%20100MHz%20-%2016bit%20ISA.jpg)

3. 16bit ISA - weird 5 port network card / switch? It has 5 RJ45 ports that are actually on the daughterboard. I've searched high and low for everything that was written on the card - no results. Photo 1 (http://89.136.157.229/vintage/Parts/Card/Weird/Unknown%205%20Port%20Network%20Card%20-%20RCE%20MM017.7%20-%2016bit%20ISA%20-%20Pic1.jpg), Photo 2 (http://89.136.157.229/vintage/Parts/Card/Weird/Unknown%205%20Port%20Network%20Card%20-%20RCE%20MM017.7%20-%2016bit%20ISA%20-%20Pic2.jpg), Photo 3 (http://89.136.157.229/vintage/Parts/Card/Weird/Unknown%205%20Port%20Network%20Card%20-%20RCE%20MM017.7%20-%2016bit%20ISA%20-%20Pic3.jpg)

4. 16bit ISA - I have no idea what this could be. It has a single DB15 connector, 2 x 30pin SIMM slots and a bunch of chips that I've only seen the likes of on some video capture cards, but then what's with the DB15 connector? Maybe you have some ideea... Photo (http://89.136.157.229/vintage/Parts/Card/Weird/TiL%20Systems%2050236-027%20-%2016bit%20ISA.jpg)

Well, that's about it... I have some other I can't identify, but they're not that important [VLB graphics, ISA sound cards and I/O cards].

So, if you have any idea about these things... post, don't be shy :)

Cheers ;)

I encountered stuff like that during the salvage and breakdown of old work cell machines that came out of factories. Found a lot of 386 cards like #2, only bigger. #1 and 4 could be controllers from a work cell or something. All of that was a blind shot in the dark though.

Well, #1 is a MGP (MonoGraphic Printer), looks like a standard clone card.

#2 I thought at first was a multi-modem card, but, the connectors have 8 connectors, so, it's probably some sort of network controller.

#3 is, obviously, a computer on a card, as you suspected.

#4 Don't have a clue.

Look on the back of the cards and see if you can find a FFC ID number, that would make identifying them much easier

Ahh, you're just guessing D (or did the initials 'MGP' on the upper left corner give it away?)...

fxg,

I can't quite make out all the markings on the Zylog chip in #4. Could you type-in the markings? It appears to be a (Z80-based?) controller for something, mebbe some machine or some lab equipment or similar, mebbe even some kind of communications controller. It might not even be a stand-alone, but work in unison with another board.

#2 does appear to be an sbc for use in a backplane system.

Did all of the cards come out of the same system? Are there any FCC ID numbers on any of them?

Xilinx makes FPGA stuff these days, so #4 probably is some kind of programmer. About the DB15, it might have once, long ago been connected to a chip socket outside the box. Why would it have it's own ram? Only guess is to drop in the card and connect it with a 512k 8088 or similar machine that didn't have an easy ram/proc upgrade. One price, complete package, no mess.

Best guess.

Did ya mix up #2 & #3? Probably not a modem card, but could well be a custom multi-port serial card. FWIW, TIL (if it's the same TIL Systems) were big in stock quote terminal systems (I worked with some of their older stuff and still have a few pieces), so this may be parts of a remote (RS232?) terminal node controller (after my time unfortunately).

And just in case it wasn't clear, the 15pin connector on the MGP is for a mono TTL (probably Hercules-compatible) display, while the DB-25 is a printer port.

I mix up item numbers, he mixes up port size and actually means "...the 9 pin connector on the MGP..." :)

Yeah, the MGP thing was just a lucky guess, T LOL

The multiport thing (whatever the hell the number is) could well be a serial card, but, they usually came in 4 port, 8 port and 16 port, but, that doesn't mean that someone didn't build a 5 port one.

Contrary to popular opinion, even >>>I<<< don't know EVERY piece of computer hardware LMAO

If that board is also by TIL, all bets are off; they built all sorts of custom RS-232 controllers, multi-port hubs, special keyboards etc.

Ya-huh. I believe you, Mike, thousands wouldn't, but, I do (kinda) :)

Thanks for all the replies :)

To answer your questions:

- No, there are no FCC-IDs on these cards - although I found quite a few cards that had FCC-IDs and I still couldn't find them [for example most sound cards from Aztech]

- They came to me from different sources, so surely not from the same machine

- The marking on that Zilog chip is Z80C3008VSC (http://www.icphotos.org/photo/Z80C3008VSC.html) / Z-SCC / 9705 - according to that link, it's a serial communications controller

- The 5-port thingie is not from TIL Systems [I searched through some old product lists] - I don't know what else to look for...

With the FCC numbers, you have to find a site that lets you look up the OLD numbers (pre-90, IIRC) to get anywhere.

Then you will, at least, know who make it and, in some cases, what the hell it is. From there, you can go to a TH99 site and see if you can find it and what the jumpers are (if any) else goto google; try luck; toss: End

You're just the man I've been looking for; could I interest you in some prime real estate, or perhaps a nice bridge in Brooklyn?

Said "kinda" which means "not very much, but slightly more than most people".

Ok, how about I trade you some nice beach-front property that I will guarantee will be above water during the next ice age for your US asset?

You wouldn't be talking about *my* bridge would you? I've already bought that one...TWICE!

First adapter is not only MGA compatible but Hercules graphics compatible as well - It has 8 64 Kbit DRAM chips for frame buffer. It could even have loadable character generator by 2 Kbyte Am9128 SRAM.

Damn. You guys are so good at identifying old cards I'm going to have to take pics of a few of mine which baffle me.

Aren't all MGA/MGP cards Hercules graphics compatible, with that extra 64K RAM? What other graphics standards are there for a mono TTL monitor?

But that extra 2K RAM _is_ interesting; probably indeed a RAM CG as you suggest.

It also helps to list the main chips if they can't be read from the picture.
