    I am in need of a old Intel 486 PC, 75MHz or Faster. I could also use a notebook as fast as a P90. The smaller the better, with real serial port. It needs to be in good shape.

    I would love to use an old CF-25C Toughbook at 100MHz, but most CF-25 are too fast for my application. I wish that it was possible to slow down the speed of the CPU from 166 MHz to 90 MHz.

    This will be used to program old radios and they are particularly sensitive to CPU speed.

    Would an M34 work?

    I think that the slowest version of the M34 is a 400 MHz P3, which is W A Y too fast. I need it to be slower than a P100, or a Intel 486 100 MHz.

    I've got a CF-41. I can dig it out.

    This CF-M33 had a desktop dock and floppy drive. Out in the dark there may be a CF-25.

    Laptop or desktop? In the attic I have a old desktop they use to use in school. It is a Pentium ( I think first gen) and has the "turbo" button on the front. I would have dig it out and look at the specs on it and see if it has a serial attachment on the back. The hard drive was still working and I it still has a floppy and cd drive on it I think. I think it's a first gen Pentium.

    Slowest M34 is 300 mhz Celeron. I got a 41 or 45 also with under keyboard but I haven't had any luck getting it on yet. Battery was busted and may have messed up the motherboard, but has parts if you wind up needing one for parts. Has national guard logo on it.

    The CF-25 is socketed with desktop style cpu. I have one complete CF-25 with just about all accessories made for it I have in my collection, but I do have another parted out one motherboard and CPU is still there and good. Maybe a older CPU will fit if it's too fast. It's a Mk3 Motherboard with mine being a Mk2. Got that unit for a few minor parts and it was the only way to get the missing side door for my unit.

    I also have a working cf-17 with dock and the special floppy that only works with that one dock with the 17. I will have to look up the cpu specs for it since it has been so long since I have messed with it.

    If you need to refresh your CF-25 info.

    So they did make a 100 mhz CF-25 Mk1

    CPU Field:
    Ex. CF-25LJF8EAM

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

    The fact that the CF-25 was made with a P100 is very interesting! That would be my preferred set-up. I really need it to be a notebook, I have a need to carry it in the field sometimes. I am going to start looking for a CF-25C!

    I find specs on the CF-17 from "66 MHz" to a "300 MHz Celeron Processor with 192 MB RAM." The first would do, the second spec, if true, is waaaaaayyy too fast!

    Thanks for your info!!
