TI Related -- Ebay / Heads Up Notice

910mp is a great monitor.

 

I also have one and a 510mp (15" version). I need to open it up though the colors are off and I suspect it needs a cap job.

 

I got the Samsung Syncmaster 910MP from the May eBay auction. This is the one with SCART, VGA, AV inputs.
It's DOA.
The menu functions all work.
It detects my F18A VGA input as 640x480 32.3 kHz NN (matching what another Samsung VGA monitor detects.)
However, in PC mode it is all black. Same result for other VGA sources so it's not the F18A.
In AV mode it has a static filled black and white image (from composite.)
I have ordered a re-cap kit for it. When that's in hand I'll open up the 910MP for inspection. Any other advice on what to look for?

I opened my MP910 to tie the select power; you won't need to do this with Shift838's board. However, I had a real tough time opening it and getting it back together. I don't remember if there was a hidden screw or some part that had to go back in at an angle? All I know is that it tested my patience ;) I told myself to check YouTube for any videos next time I cracked the case.

My Samsung Syncmaster 170MP (not 71" version)...maybe 17" performed well until the screen got smashed, I kept using it for audio for some time. Now it's just stuck on the shelf. Needs to go. Available for parts or refs.

 

P.S. mine came from a yard sale.

We could use the board here or the whole thing

I suspect that's where he got the four empty PEBs that he has as well. Note that though the PEBs say "tested good," none of them has a flex card (so the most he could do was a power-on test), and the two of them with old style fuse caps are missing the caps and the fuses, so he couldn't even have tested them that far. Of course, he may have the missing parts available to perform the tests--but he should note that they are missing in the auctions.

 

Note also that one of the HRD 3000 cards is missing a lot of memory chips, while the other is missing the batteries. YMMV with both cards, as when I was talking to Bud in the year or so prior to his passing, he noted that the only fully functional HRD he had left was the HRD 4000 that belonged to the Insanemultitasker. He was going to give me the others to play with/resurrect, but we never got a chance to meet up for the exchange, as his health (and mine) was somewhat questionable at the time. 3000 boards are still pretty solid cards though, so they would be good choices for reconstruction if the price was right (about half what is being asked for them right now).

His widow and I exchanged a few messages but never connected, mostly due to my health issues. The last package I received directly from Bud was a handful of cards that he wanted to get back to their owners; I repaired those cards on his behalf. I did not get the impression he had any more cards that belonged to people and that all he had left was parts or his own equipment. I do know that he was sending his personal cards to people near the end, to make up for repairs or 'lost' cards. He always tried to do right by people no matter what...

A known good 3000 is worth every bit of $300.00 if it is working and is popped out to 4 MB. It is a solid card that needs mods on occasion to take care of blind corners that the designer never anticipated. It can be taken up to 11MB but ROS won't sniff more than 4. IM has a MDOS mod that sees at least 8 so if you have a Genie then ?

 

The 3000b is a fucking bitch that if working is a golden egg but if broken will make you want to bite a chunk out of your tounge. At 4MB it is worth the the same as the 3000.

 

The 4000 is the wild card. At 8 meg native and working I would suspect it to be around $450.00. If broken then it depends on the revision of which I know there are at least two. One is easy peasy the other requires cuts and jumpers.

 

Horizon products are a mixed bag with revisions not being documented and quality being a secondary consideration. When they work they are golden. When they don't it could make your hair fall out in your hands.

 

But then that's why we are here.

I absolutely don't know what I'm looking at and there aren't any board annotations other than 1986 and 1988.

One seems fully populated (3-high stacks) while the other seems basic - both look almost new.

Any help identifying them would be appreciate since the topic came up.

I haven't had an opportunity to test them - currently four PEBs in pieces for drive, FDC 80/80/80, power supply, and fan upgrades.

 

Thanks in advance, Gurus. ;-)

If there is a serial number under the heat sink for the first one, it should show 01XXX, which would make it the HRD 1000. Based on the serial number and the board layout, the other one is an HRD 2000.

 

And I agree with Marc that a fully functional 4M 3000 board is worth a lot more than my suggested price above--but my price was based on the fact that both boards would likely need a lot of work to bring them back to life, not fully functional boards.

I have the disks but i can read only the Terminal Emulator one, maybe the MRS disks needed for a particular controller or formatted different compared to the floppy disks of the Standard TI.
Maybe readable only with the Z80 card inserted ?

I also could try to save them with the Kryoflux card.

As much as I like my BwG, if that CorComp works and there is an 80 track mod for the DSR, I would like to grab it.

 

Well, shit on me... I figured it would not last too long.

 

Why don't we have a FPGA implementation of a WD1793 yet? :-)

 

I know, one should not just put up a request here and expect others to do the job; I'd just like to mention that the floppy controllers like the WD series are really well documented, up to the state machine - we implemented them and the HDC9234 in MAME. I guess they definitely score lower on the skill scale than a graphics chip.

 

Maybe a possible future project?

The disks are NOT readable with a TI. IIRC, they use a Kaypro CP/M disk format. You can only copy them on a TI with the Z-80 card, or on a PC with a Cryoflux or a SuperCardPro. I suspect that the old Uniform program would also copy them without issue. . .

Some of the guys here have TRS-80 Model III's, that and copy of good old "Super-U" and it'll copy damn near anything.

Or my kaypro

If they are double-density we can also read them on a Commodore 1571 (stupid thing is hard-wired in MFM mode.)

 

Also, somewhere in my trove of stuff is a copy of 22disk.
