1. This is Connect 34 Wave. Listed as 2SCO34G
https://www.ebay.co.uk/p/IBM-Mwave-Mdsp2780-2 … -ISA/2005278275
readable is:
miro CONNECT 34 wave label at modem module
small miro bus chip
Crystal logo at codec chip
long connector - EIDE?
short connector with one jumper - for radio module or jumper setting
no other pins for jumpers
- unknown is PCB revision, And photo of back side.

2.
unnamed card listed as Connect 34 od Dolphin - i think wrong name and this card is Online PnP
https://www.ebay.de/itm/ISA-Modem-u-Soundcard … tc/323683728418
big uPD bus chip
Crystal codec chip
long connector - EIDE?
short connector named Radio - one jumper in same position as at first card
no other jumpers
MIRGER2.7 label at modem
YPCB-BRAZA-2.7 , FCCID LAHCON34-ISA-2 and miro logo printed at PCB front side
BRAZIL2.7 label at back sice
unreadable if is another YPCB-BRAZA photoetched to PCB.
etched 4396 is week of 1996? Chips are probably from 1996 too.
FCC ID was registered August 1996 https://fccid.io/LAHCON34-ISA-2 - Pinnacle is miro
Why is name CON34 if card name is not Connect34? Probably because they already registered https://fccid.io/LAHCON34-ISA-1 for older cards,

3.
unknown card with modem removed:
https://www.ebay.com/itm/323554954168?
small bus chip without miro logo - amd PAL?
MVA416 codec
Long connector - is 2nd IDE readable?
short connector - radio connector at early PCB card?
no other jumpers - only pins for CD and TV internal audio cables
YPCB-BRAZA-2.2 etched readable near SRAM chips. etched miro logo readable near jacks because modem module is removed.
2SC034G-ISX41 at backside label
Is this card Connect 34 or Connect 32 Wave? Is PCB same as first card which is Wave? i cant see differences. Only buschip and codec without logo.

4. Packard Bell miro card:
https://i.pinimg.com/originals/5d/db/b9/5ddbb … aff93205bd5.jpg
Now confusion for me. is this card miro Cassius?
If yes, is Plug and Play? if yes, why use small bus chip like older nonPnP cards?
sadly YPBC-BRAZ2.x is unreadable
Is name at modem label 2SCONN 34? Is it Connect 34 or Connect 34 Wave with added PnP function?

5. YPCB-BRAZA2.2 with modem removed again
https://allegro.pl/oferta/karta-muzyczna-miro … 2780-7907373371
Almost same as card number .
Codec again MVA416.
But now bus chip with miro logo and is readable:
BRICB1-12
ORBIT 6577A
year is 1996?

They wrote for "miroMEDIA Online" and not for miroConnect34 Wave.

Archived miro website from 1997 year:

Only miroMedia Online. No info about Connect 34 series
Card is named only Online and not Online PnP. But from spect is Plug and Play.
Modem is only 28?

Nexht confusion 🙁
Are Online and Online PnP two separate cards?

and next..
mirosupport linked Online (separate from Online PnP) manual to Connect 34:
http://www.mirosupport.de/commu/online/monlineg.pdf
But file is named online. And inside manual is only Connect without 34 and without Wave

Online PnP manual have PnP in name: http://www.mirosupport.de/commu/online/mopnpg.pdf

Post from Bancho.
is this first version of the card 2.1?
Is it YPCB-BRAZA2.1?
If yes, is it miroConnect 34 or 34 Wave?

Just some Sound cards today. Labway ESS Solo-1 and what i think is a Miro Connect 34 Wave Minus the Modem Module.

Just wanted to add a few pictures of my miro connect34 for the history books 😉

Regarding the 28k/34 confusion:
Firstly, the original ITU-T V.34 standard defined a 28.8kbps data rate. The '34' in the names of these devices referenced that standard, not a 33.6kbps rate, so there's no contradiction there.

But... the mWave was an advanced DSP and these cards were basically software modems with the software running on the DSP, not the system CPU. That meant that the actual modem functionality could be upgraded.

In 1996, the V.34 standard was updated to support 33.6kbps data rates. This was sometimes referred to as V.34bis or V.34plus, but the standard remained V.34.

IBM upgraded the mWave basecode to allow the modem to be upgraded to V.34-1996 standard and 33.6kbps data rates. Not 100% sure if Miro released drivers based on them, but this was at the peak of Miro's success and fame, so I suspect they would have.
