There are 3 'marks' of CF-25.

Regarding the last character of the model numbers, M = USA/Canada, E = UK, G = Germany. The machines have the same specifications but different keyboards and included power cords.

Common to all:

   HDD type: EIDE/ATA
   RAM type: 144 pin 60/70ns 3.3V EDO SODIMM
   Please note that some newer memory types can fit in the slot, but will not work. You must use EDO memory!
   Audio: 16 bit 44.1KHz w/mono speaker and headphone jack; for specific hardware details see each Mark.
   Keyboard: sealed matrix water resistent rubber dome 87 keys (USA) or 89 keys (UK). German keyboard is not currently known. Note: it's been reported that despite the same layout, the keyboards between different marks may not be electrically compatible (or at least the little interface PCB that the keyboard and trackpad connect into)
   Pointing device: capacitive track pad approx 2x1.5"
   PCMCIA: 3 slots for Type I or II (bottom two are Type III aka Cardbus, bottommost is also ZV) all of which support 3.3V 400mA/5V 400mA/12V 120mA (current ratings are for all 3 slots combined)
   I/O: DE9 serial, DE15 VGA video, DB25 parallel, PS/2 mouse/keyboard (both combined on one port - either device type can be used on port, and common splitters do work), IrDA infrared
   AC Adapter: input AC 100-240V 50/60Hz auto sensing, output DC 15V 2.6A
   MP bay FDD: 1.44MB DSHD/720KB DSDD (high density/low density support). Note: no model seems to have included CD-ROM as standard equipment.
   Original OS: Windows 95
   Screen type: Active Matrix TFT LCD (except one model, indicated below) with native resolution of 800x600

Lacking Information

Specs have been "decoded" using the information in Reply #7. Some info is still lacking however.

   CF-25EGC4CAM - Pentium 133, 10.4", 1.35 or 1.44GB HDD (which?), 16MB, Mk2
   CF-25FJF4CAM - Pentium 150, 12.1", 2 or 2.1GB HDD (which?), 16MB, Mk2
   CF-25FXF4CAM - Pentium 150, 12.1", 2 or 2.1GB HDD (which?), 16MB, Mk2
   CF-25LGM8EAM - Pentium MMX 166, 10.4", unknown HDD, 32MB, Mk3
   CF-25LJM8EAM - Pentium MMX 166, 12.1", unknown HDD, 32MB, Mk3


Decoding CF-25 Model Numbers

According to the service manual for Mark 1 CF-25s (order no. CPD9609026CO), this is what the different positions in the model number represent:

CF-25abcdAAe

Where... a represents equipped CPU b represents LCD type c represents hard drive capacity d represents RAM capacity e represents region

Though the service manual does not specify the mark or marks it applies to, we know it applies only to mark 1s because it only provides options for those variables that correspond to mark 1 CF-25s.

By running the Mark 2 and Mark 3 models through this pattern we will be able to figure out what the unknown letters represent.

CPU Field

Ex. CF-25LJF8EAM

C - Pentium 100MHz D - Pentium 120MHz E - Pentium 133MHz F - Pentium 150MHz L - Pentium MMX 166MHz

LCD Field

Ex. CF-25LJF8EAM

G - 10.4" TFT J - 12.1" TFT V - 12.1" STN X - 12.1" TFT

Multiple 12.1s might be explained by different suppliers.

Hard Drive Field

Ex. CF-25LJF8EAM

8 - 840MB C - 1.35GB, 1.44GB F - 2GB, 2.1GB M - ???

RAM Field

Ex. CF-25LJF8EAM

2 - 8MB built in 4 - 16MB built in 8 - 32MB built in

Unknown two-letter code

Ex. CF-25LJF8EAM

It looks like this might actually indicate the mark, but there isn't quite enough info to confirm this yet. If that is what it means, this is what they translate to:

AA - Mk 1 CA - Mk 2 DA - Mk 2 EA - Mk 3

Region/Area Field

Ex. CF-25LJF8EAM

E - UK G - DE M - USA/CAN
