I'm pretty sure I have the manual for both the original GVP A1230+ and 1230+ Series II.  Unfortunately, I have them at home, and won't be there until this evening.  

Just to confirm, you have the original GVP A1230+ that has no clock battery and no expansion port on it, correct?  (No place to plug a SCSI module...)

Crap...  I forgot all about this thread.  I did find my manual, though, and have a PDF of it I scanned.  Anyhow, for GVP A1230 Turbo+ (original) you are correct, the only change is remove J5 for 16MB SIMMS.  Also, largest sized SIMM must go in Slot 1.

A1230 Turbo+ (original) Jumpers:
J1 - ON - 68020 / (OFF - 68030)
J2 - RESERVED (ON)
J3 - RESERVED (OFF)
J4 - RESERVED (OFF)
J5 - (ON - No 16MB SIMMS) / OFF - 16MB SIMMS PRESENT
J6 - RESERVED (OFF)

CN4 - RESERVED (OFF)
CN5 - (ON - 4k REFRESH DRAM 16M) / OFF - 2k REFRESH DRAM 16M
CN6 - RESERVED (ON)
CN7 - RESERVED (OFF)

(.)=DEFAULT

So, PM me your email address, if you want a PDF manual for any of the following:
GVP A1230 Turbo+ (original, no expansion port)
GVP A1230 Turbo+ Series II
GVP A1291 SCSI Kit Performance Series II (SCSI expansion for A1230+ Series II)
