I've searched and found threads on this subject, but I didn't see one that had an actual conclusion. I have one of the earlier REVs that has the screen collapse between P1 and P2. I actually like the way it looks, but there's also a problem where on certain levels, the spot killer kicks in and the screen goes blank for a fraction of a second. In one of the Tempest or WG6100 user faqs it mentions this only happening on the figure 8 levels, but it happens on others as well. In fact, if the X-Y on the board is adjusted so that the image fills up the entire screen (as described in the Tempest manual), it happens on nearly every level. So, I've adjusted it down, but it still happens more than I like. The listed fix for this was to replace the ROMs with REV 3. Has nyone actually done this and can confirm it fixes the collapse issue? Also, it says the REV3 ROMs are 32kb, so there are half as many. Do I just put them in every other soicket (ROMX, 1, 3, etc.)?
 
Rev 3 will correct the collapse for 6100 monitors with the newer neck boards. i forget what number board they are. you will have to replace every other one except the vector roms . you will also need to have a newer rev board to change jumpers w1 and w2 to w3 and w4. Ill look a bit more to confirm board revs and post.
 
Cool, I was always curious what was different about the Tempest pcb regarding the 2716 eproms and the 2732 ver3 set up. I have a wg k6102 in my starwars. At one time, it was in my tempest. They added a few lines of text, on the bottom of intermission screen, when it goes from player 1 to player 2. That way it utilizes the entire screen. At one point I had the rev3 images that had been split and placed on 2716's. Unfortunately those files are on a hard drive in a Windows 98 computer that is no longer functioning.

Thanks for the info. Sounds like it might be more trouble (and $$) than I was hoping for. I'll check out my neckboard tonight and post any markings- maybe it's one that can be used? If not, what's the probability of finding one?

In unexpected (but not) news, I played it for about 40 min yesterday. Guess what? No mid game collapse AND no P1->P2 collapse. I haven't made any adjustments to this machine in months and haven't played it in a couple weeks. I don't know what happened, but I'm hoping it stays this way.
 
As I recall, there is only 2 roms that are different from rev 1 to rev 3 if you are using 2716's.
One of the rom's was to remove a cheat which was rev. 2.
So really it's just finding someone who has the two rom images and burning them to a 2716. Tempest is a great game but I can't hook you up at this time. It does work as stated.
I sold off my one boardset that had those images. The tempest I have now has the original WG k6100, that does not collapse.
 
I'm not so much worried about the ROMs as finding the correct neckboard that Talon2000 said I need for it to work properly.
 
I was not aware of a neck board requirement so I am interested there as well. ROM wise there is already a 25/2716 version of the Rev 3 ROMs out there floating around. More or less its the Rev3 2732 set split to 25/2716 image size.

I found them a couple of years ago. I was wanting to upgrade to REV 3 but also have a switching kit for Tempest Tubes. Its been a LONG time but I want to say my origional setup was the board with Rev 1 or 2 on 2516s. The Tubes mod is based on the 25/2716 EPROM file size. I "think" I was going to convert to Rev 3 on 2732 EPROMs then take the appropriate 25/2716 file and combine it with the 25/2716 sized Tubes file to make the proper 2732 image for the proper EPROM position. At that point I could combine that with the correct 2732 image for that position and program that to a 2764 and make a switchable kit. I ended up finding the Rev 3 version of Tempest that someone had already split to the 25/2716 image size. At that point it was a matter of upgrading a couple of the EPROMs. Most of the code is the same through all three versions. I then made a switchable tubes kit out of a 2732.
 
Yes, that site was informative. I think I read it before, but it didn't sink in until I read it again. So I only need two ROMs, but it has to be the REV 3 ROMs split into 2716's. All of my ROMs are 1xx, so I guess I have Rev 1 ROMs. Weird thing is my serial is 15357 (cab, board and monitor frame all match), so they were using this Rev for quite a while.

I checked out my neckboard (without removing it), and the only markings I saw were "P315", "A" and "85X0146." All the rest looked like component location markings. I did not see any jumpers, but I can't see the lower left corner without removing the neckboard.
 
I did not see any jumpers, but I can't see the lower left corner without removing the neckboard.

The jumpers (strapping) is done on the main pcb, not the neckboard.
And only needs done if changing rom types. i.e. going from 2532's to 2716's and vice versa.
 
Still trying to find my notes.

Edit.. It was the Deflection board. P329 causes Collapse between P1 and P2

P314, p327 Work, and P329 Needs Rev 3.

Look at what boards your 6100 has. Typically most of the monitors I have worked on had P315 and p327 so there was never a problem.

As for converting your tempest board to Rev 3 you can burn 2716s, or you can burn 2732's in which case you will need to change jumpers on the board.

I think there's a website with the 2716 Rev 3 version you can download.

Otherwise you would have to split the 2732 version

OK, my neckboard is P315. Were you stating it should not have the collapse issue to begin with, or after the Rev 3 ROMs were installed it won't have any problems?
 
I am having the same issue when my Tempest switches between P1 and P2, the display gets crushed......(P329 Deflection PCB)
Currently there are r.2 ROMs on my PCB so from research, I should only have to swap H1 and K1 with 136002-316 and 136002-318 respectively?

Would anyone have these files available? (please).

Thanks

I had Steph burn me the ROMs but I ended up installing the Vector Labs multi kit and never did the ROMs. Odd thing is, even when playing Rev 1 the display no longer collapses.
 
Tempest eproms needed

Can anyone point me to someone who can burn me all the eproms for a TEMEPST? I bought a gorgeous cabinet today, with everything there but the actual chips. Anybody's help is appreciated...who is Steph?

I plan on putting together a universal rom replacement daughterboard for 6502
basically this
http://www.arcade-cabinets.com/board_hacks/VICDUAL-DB/

but for 6502 games like tempest, asteroids, MC basically ones that have tons of ROMs that replacing all the roms is not cost effective. my boards should be here literally any day now.

but if your looking to replace the whole set Steph @ hobbyroms.com is the man to go to, great guy! just gets expensive to replace all 12 2716 or whatever on tempest.
