Powerbook 1x0 CPU accelerators - did they exist?

[Byrd]

Hi,

I've been taking apart my PB100 tonight, reseating the RAM and CPU daughtercard to thankfully result in one working machine (HD is dead though, argh it was a nice 270MB unit!). It really is a dream to work on, and sad that later models make it so much harder to disassemble (MBP Retina anyone?)

With all of the PowerBook 1x0 models having removable CPU daughtercards, does anyone recall any CPU upgrades/accelerators available for them? Alternately, is a higher rated part from say a 33Mhz Powerbook 180 interchangable with the card from a 16Mhz Powerbook 140?

I don't know about the rest of the series, but the 100 was my first 'Book, hence my longtime love affair with the later Duos.

The only internal expansion or acceleration option I can recall, other than the modem, was a (RAM interfaced) Video Card for the 100. Dunno about the rest of the series, I used BabyPB until I was forced to move to a used Duo 230 because the 68000 was no longer supported by newer versions of primary apps..

As for the powerbook 140: you can swap the daughter card from a PB170: that will give you a 25 Mhz 68030 instead of 16 Mhz.

You can go for a 33 Mhz CPU but then you have to take the daughter card and the interconnect board of a PB165.

I believe newer or asante made an ethernet expansion card for the 100 series.

The PB160/180 daughter boards will not go into the 140 or 145. RAM expansion cards were differently specified for 140/170 and 160/180 series. Both types will work at least in the 160/180, but the older types may throttle RAM throughput in the newer machines. For the 170 a second video card was available in the form factor of a RAM expansion card. Rarely there were offers for overclocked 180s running at 40 instead of 33 MHz. The early PowerBooks were fast machines in their age, extremely high priced and with few room for improvement (given you chose a top of the line model like the 180).

I was doing a search as I found a dead 170 with a video card in it. It attaches to the memory slot and has a S video cable that is long enough to reach out the back. It has two types of ram on it. I am wondering is it ram for both video and powerbook memory? Does it need drivers? It says 140 and 170 so that would be cool to put in one and see it put out to TV or whatever. If anyone knows specs or has more info on the Lifetime Memory Products Inc. card for the PWRBK 140/170 I would love to see it.
