Assuming it's functional (which could, I guess, be assuming a lot),
anybody got a ballpark number for value (or an offer to buy) for it?
Don't say "go look at eBay" if you've got an answer. Wading through the graphics-disaster that eBay has become is more effort that the result is worth, particularly across this cocktail straw of a connection I'm stuck calling my internet connection.

To be honest, they seem to be fetching about $20-30 generally. The Woz edition isn't that rare and people get more use out of a ROM 01 or 03 (non-upgraded Woz's are ROM 00, and actually are quite thin on the ground).
Powering it up with nothing in the drive shows me "Apple IIgs" at the
top of the screen, a 1977-1987 copyright date/all rights... message, and "ROM Version 1.0" before it kicks over to the "check startup device"
screen a couple seconds later.
Presumably, this would indicate I'm now the proud owner of a ROM 01 Woz Edition gs? Or is 1.0 the number that a ROM 00 machine would show?
Any way to make a determination *FOR SURE* without needing anything more than the keyboard to do it? (a PEEK() or three, perhaps?) I've got
FWIW: Dug out a power cable and set this thing up using a spare Mac keyboard/rodent, and as expected, it does indeed fire right up.

Basically, a Woz edition GS is if you have a case with the Woz signature
on the front of it, and is usually a ROM 00 board (although it's
possible that owners had the board swap for a ROM 01 while retaining the Woz-signed case).
ROM 00 is a machine that doesn't say 'ROM' at the machine startup screen.
ROM 01 is a machine that says 'ROM Version 1' at machine startup screen.
ROM 03 is a machine that says 'ROM Version 3' at machine startup screen.

Sure, piece of cake. David Empson posted this 4 days short of 10 years
ago, and should do the job. (Good, because I'm away from the IIGS and
tech refs at the moment)
5000 REM IDENTIFY A IIGS
5010 I = 768
5020 READ J: IF J < 0 THEN GOTO 5040
5030 POKE I,J: I = I + 1: GOTO 5020
5040 CALL 768
5050 GS = PEEK(0): REM 1 IF IIgs
5060 GV = PEEK(1): REM IIgs ROM VERSION
5070 RETURN
5080 DATA 169,0,133,0,133,1,56,32,31,254,176,4,132,1,230,0,96,-1
The way to use this is:
GOSUB 5000
PRINT GS
PRINT GV
GS should be set to '1' if it's really a IIGS
GV will be set to the ROM version (0, 1, or 3)
For the interested, the assembly language listing for that small program is:
0300- A9 00 LDA #$00
0302- 85 00 STA $00
0304- 85 01 STA $01
0306- 38 SEC
0307- 20 1F FE JSR $FE1F
030A- B0 04 BCS $0310
030C- 84 01 STY $01
030E- E6 00 INC $00
0311- 60 RTS

Spiffy! :)
Looks like it's "really" a GS, and it's showing as a ROM 01. I guess
somebody got the upgrade done on it. Thanks!
I guess my next move is to start trying to acquire some GS-targeted
books...
Basically, a Woz edition GS is if you have a case with the Woz signature

ROM 01 upgrades did not involve a motherboard swap. It was only a ROM chip swap and (if the board was early enough) a VGC chip swap.
