Duo upgrade update . . .

Hi, all, just thought I'd post post the latest PCB artwork of the 1400 Card Cage for the Duo-PCMCIA hack project:

If interested, you can find background info on this continuing project in the original 'fritter thread: PB 1400c IC Conundrum?

. . . and to see what I've been working from to develop this artwork, check out the individual board scans: PCB Torture . . . an' Reverse Engineering . . .

I couldn't dredge up the 'fritter thread . . . IIRC, there weren't any responses anyway . . .

p.s. as usual, please "add another comment" rather than "replying" to this post . . . at least until I have time to fix links & hunt down typos . . .

dare I say...w00t

Glad to see you're back in the saddle.

I just re-read the old threads, and it's got me all hyped to see if you can pull this off. It's enough above my head that I can't expect to replicate it, only appreciate it.

I'll just put my feet up and enjoy the ride. Acute

2300c -> G3 artwork update . . .

. . . been playing with the other end of the Card Cage interboard connector! I'm starting with the 603e pinouts on the 1400 117 MHz processor card to decipher the PBX pinout to get a handle on what the 1400's bridged 030 I/O bus looks like. Hopefully the Card Cage's connector function will be very similar to the Duo's docking connector . . .

Riiigggghhhhtttttttt! ::)

Here's the latest processor card artwork for anyone interested to peek at:

Haven't even de-chipped the PCB yet and I'm down to under 30 undocumented pins out of 240, but the confuzzled count is probably closer to 60 pins. Dunno what the count breakdown is on the interboard connector yet . . .

. . . whatever, at least this stuff is a LOT more entertaining than watching TV!

edit: looks like about 26 of 160 pins on the interboard connectors need to be run down. I have a feeling most of these will fall into place after the connectors and components fall outa' place!

HEH! :ebc:
