Pulled this Sound Blaster out of a machine I recently picked up...

Board is marked CT-1320U
Is this considered a SB 1.0? or 1.5? Google says it's a 1.5, but it has CMS chips, so I think it's considered a 1.0?

The chips could have been added after the fact since sockets were included on the later CT-1320B/C/U models.

Given it's an CT-1320U, I believe it would be considered an SB 1.5.

Reading this blog post it sounds like it may depend on whether the card was shipped with the CMS chips and which box it came in: Sound Blaster 1.0 or 1.5?

Great find on that link... Ok, My CMS chips are soldered and not socketed. The solder work looks factory to me. Same quality as the other components around it, no flux, etc.. So this card would have been sold as a SB 1.0 from the factory most likely...

Ah, didn't notice they were soldered. Yes, that would likely be an SB 1.0 then.

Positive PC1000

I got this pc as part of a 3 pc and a laptop lot I found while thrifting. Luckly I found a Sound Blaster Pro inside with the CD drive. The onboard VGA is kinda good for an ISA bus card.

^ Really Nice ! Lots of great vintage parts. the mobo reminds me of an early Unisys 486 lpx board.

looks to be made by Tandon Corporation. The case is engineered around the mainboard. The Microchannel CPU daughterboard would only work in this case. I tried to do some research and theres not much out there. This might of been their last PC, and probably rare to find in the states as wiki states by 1989 90% of its pc sales were in europe. Positive may have been a front for Tandon Corp as both companys were out of Chatsworth.

+1 for feet 😁

"Oral History of Jugi Tandon" - Computer History Museum https://www.youtube.com/watch?v=hf7RK8xYwG8 Jugi was obsessed with making PC clones. Iv seen a few of Tandon computers inside. All overbuild with no regard to DFMA or cost. Huge pcbs, custom form factors, lots of connectors, tons of screws and custom brackets, sticking to custom chipsets even after flood of cheap Taiwan third party ones. I think PCs is what finally killed Tandon 🙁

thanks, confimed my suspicion after further disassemble. Official name is "Tandon Halfling" I dont have a better camera.

A Terratec ESS Solo-1 for my DOS gaming machine, 5€. It seems to be very compatible if I look at Phil's Computer Lab video about it.

I am equally discontent with manufacturers putting the Fn key on the bottom left where the Ctrl key should be. IBM and Lenovo does this. It's very annoying.

At least one Lenovo laptop I had had a BIOS option to swap Fn and Ctrl. About a 6th gen i5 I think, don't know if the option was there before then... or even since.

I was chuffed to find the choice, check your machines' BIOSes.

There's at least one 3rd party BIOS for the early lenovo thinkpads that enables this (google middleton bios)

Nice, and you got one that is populated with amps and a wavetable header. 😀

Based on my own recent testing, these cards are over 90% compatible with DOS titles.

And we have the second mobo that I got to work from the lot posted above - DTK PRM-27i E0.

Test GPU - V3 3000 16MB, TVout version.

Ah nice, I'll read that thread! At the moment I can test the card successfully with the games configuration utilities (Duke Nukem 3D, Warcraft 2...), the sound plays fine. But as soon as I run the games, at the first note the system freezes. But I didn't debug very much at this point.

...and I lost a good 10 minutes until I realised that on my card the Line Out connector is the black one, not the green like on every other sound card.

a couple voodoos.

Wow. I forgot about those. Gorgeous

both were not working, gold one had key board controller error refused to boot. I rolled my face across it several times and slapped the hell out of it for good measure a few times and it fixed it. The green one wouldn't post at all. What are the chances that both sticks of ddr in it were bad. That was the case after I salvaged ram from a junk t42 and changed it works too now also. 😀

still both need alot of work gold one needs a total tear down for fan and thermal paste restore. green one isnt as bad just paste and compressed air i think. cmos batteries etc etc and i need power bricks for the both as neither have.

I can confirm that compatibility with the Solo-1 is very good. However, whatever method it uses to emulate DMA will still fail on some chipsets. This card did not work at all on my Socket 775 system, for example.
