PCMCIA /A with Three 50 Pin Ports 67G5055 2-Slot PCMCIA [Stinger]
[Ed] this is a stump the chump card set. My guess... The rear access adapter shares the same FRU as the Japanese 2 slot rear loading PCMCIA /A. This card set is an earlier FRU, and advances in design eliminated the need for the detached card. Note that a FRU relates to functional equivalence, where this card is a rear slot model, and the Japanese rear loading PCMCIA /A is also a rear slot model. The Japanese 2 slot rear loading PCMCIA -MIGHT- be a reduced cost version...
PCMCIA Three Header, Front
Oddly, I cannot make out ANY traces going to the MCA edge connectors. It appears that there is a whoppin' big ground plane.
Note the utter lack of ANY chip. Not even a SIMMple logic chip to support POSID. Other MCA adapters exist that lack any POSID, and are invisible to POS [example - a gamecard]. These cards sit on the bus and respond to industry standard I/O addresses.

Again, where are ANY traces to the edge contacts?

Full WinNT4 Support
David Ress was stalking the chimera, and bagged it!
I would like to report that I just finished testing my PCMCIA Adapter/A under NT, and it looks like all is well. Looks like CardWare for NT solves our problem. Latest version is 6.00.041, and this version includes the refinements to work with the MCA bus. The download is a trial version that only works for 14 days.
Tested a 3Com EtherLink III LAN PC Card (model 3C589D-TP) and it found it right away. Interesting enough, it provided me with the IO address, IRQ and other information necessary to install it, including opening the Network control panel. Oh, you need SP6 in order to install CardWare for NT.
I have been experimenting with the CardWare for NT software for the past two nights, and based on the cards I have tried, I can honestly say that if the pcmcia card is on CardWare's list of supported adapters, it will work no problems. If it is not, then it takes a little monkeying.
That said, it appears that New Media GameJammer and WAVJammer appears to be the only sound pcmcia adapter on CardWare's list. Does this mean your card does not work, of course not. My DaqCard-1200 from National Instruments is not listed either. It mounts, but CardWare for NT is not aware of its driver. Just takes some fiddling with the PC Card Database.
For supported adapters, it may simply require the installation of a driver and a reboot - as I found out last night with the Adaptec APA1640 SlimSCSI card (needs sparrow.sys). Funny, for a while I had four SCSI adapters in my 9533. Tall about overkill.
Half-Assed W95 Support
From the god-Emperor of Microchannel
Well, I am reporting "success" with the Stinger under W95. I got a mixed result that you all might accept- Install Ezplay. When it complains about not being able to rename config.pcm to config.sys, hit OK. Fire up Exploiter and save c:\ezplay\config.pcm as c:\config.sys
Now open up c:\windows\ios.ini and add "diskdrv.sys" to the area with the rest of the IBM PCMCIA drivers. Reboot.
Results- you will be able to use your hard drives in protected mode. The two PCMCIA slots and your CD Rom will be in compatibility mode. You got to suffer a little bit...
The problem seems to be when IOS tries to issue Int 25 commands to the PCMCIA and CD. The diskdrv.sys is the crux of the matter. Look in IOS.LOG for errors.
I tried must_chain, non_disk, monolithic. I got the same results with just the diskdrv.sys entry, so I just left it that way. I'm not totally sure what this will do with communications and network PC cards. It worked with my 105MB PCMCIA HD. YMMD
95 Bezel Hack
Got tired of the dorky look of a bare B: drive bay. Did some measurements and started cutting. Basically, you cut the bottom of the PCMCIA opening flush with the bottom of the horizontal angle of the blank floppy cover.
Measure 1.5" from the left and right edges of the floppy bezel. Those are the edges of the left and right side of the opening. I am still fighting with the top edge of the opening. .43" was too low. Much easier to cut excess away than put it back....
More Refined 95 Bezel "Hack"
This centers the 'drive' vertically in
the bezel opening with ample clearance to insert/remove
the PCMCIA cards. NO BEZEL HACKING REQUIRED. (Ed. What fun is that?)

Personal Experience- To install the dual slot adapter under OS/2 v.3, go to OS/2 System, System Setup, Selective Install, click on the button to the left of PCMCIA Support, choose the IBM ThinkPad 720.
Preparing this Adapter for Use
Adapter does not operate
1. Confirm logic card is installed correctly in computer's 16-Bit slot.
2. Confirm bay card is installed correctly in a 3.5 or 5.25 Inch bay.
3. Confirm that device drivers and support software have been installed and are operational. You will see a response from these drivers during the power on or re-booting sequence. (Ed. Use F8 during boot to do a step-by-step confirmation under Doze/W95)

PCMCIA card does not operate

Error message Invalid Drive
Insert the following statement in the CONFIG.SYS before any device driver statements: lastdrive = # where # equals the letter of the last drive in the system. You must include two letters for the adapter and letters for all of the previously configured drives.
DOS Configuration Example
The CONFIG.SYS File
The letter x specifies the Socket Services already
installed on the computer.
/baseslot=n This option sets the base slot address, where n specifies whether the address begins at (0) or (1). The default is 1. Set this switch to 0 only if you have a problem addressing the slots. If a value other than 0 or 1 is specified, this switch is ignored and the default setting is restored.
/stbtime=n This option enables standby mode, where n specifies number of minutes that elapse before card goes to standby mode. The min value is 5 minutes, the max is 20 minutes. If a value greater than 20 is specified, this switch is ignored. All sockets are affected when you set this switch. (This feature does not support solid state cards.)
OS/2 CONFIG.SYS file sequence
switch options for the main
/s:n Recognizes PCMCIA sockets, where n specifies number of physical PCMCIA sockets available. The default is 2, max is 4 sockets.
specific PCMCIA sockets, where m specifies logical
socket number to be ignored. Multiple settings are
allowed. This is useful when a Type III card physically
occupies two sockets.
/stbtime:n Enables standby mode. (Same as above for DOS stbtime option)
/b This option specifies the OS/2 operating system to start (boot) from the PCMCIA-ATA card. If you specify this option, then PCMCIA.ADD module decreases the number of sockets specified by the /s switch because the startup PCMCIA-ATA card is treated as an internal IDE hard disk, not a PCMCIA-ATA card. When the OS/2 operating system starts (boots) from the PCMCIA-ATA card, if you use the /s:4 option w/o the /b option, the disk assigned to the last drive-letter will not be assigned to any physical socket. (To make this PC Card a bootable PC Card, see the documentation that came with the OS/2 operating system.)
Notes About the /b Option
Type I, II, III. Function of each type is only restricted by size.
Type I -3.3mm thick SRAM or EEPROM memory cards.
Type II -5.0mm thick, include SCSI, sound, modems, NIC, external device interfaces
Type III -10.5mm thick cards that are most often hard drives.

I/O address. Each adapter must have a unique address range.

The option disk ADF is 08/10/1994
Further meditation shows the 94 version fixedresources has pos[4-7] added.
Option disk fixedresources pos is 10100011b, Peter's pos is XXXX0011b
Option disk '94
Option Disk uses pos and pos, Peter's uses pos and pos
Prompt "I/O Address"
So, the two ADFs are different, the '94 version adds more fixedresources, changes the pos[x] used for I/O, and now has been pared down to only TWO I/O addresses. It sure seems like IBM wouldn't want so many I/O choices, that would make troubleshooting more complex, plus 003E0-003E1 and 003E2-003E3 are used by the VADEM VG-468.
