I have them all, i.e., 64, 64C, and a 64 in a 64C look alike case. Although
not as common as the classic 64, the 64C is not at all rare. I found a
complete one with a matching 1541C drive at a thrift the other day for $5.
Among the Commodore community the consensus is that although functionally
the same, some of the chips in the 64C had been upgraded (if I remember
correctly, specificly the sound chips among others), and it is therefore
more desirable than the standard 64.

I suspect that here in Sydney, Australia the price of PS/2's is about to
tumble to insignificance. It seems a lot of corporations bought whole
networks of them in the early 90's and they are at the end of their
usefulness when they move away from DOS/Win3.1 I have recently seen model
70 boxes advertised for $A30 and actually acquired a model 76 box for $A70,
with 8Mb and 200Mb SCSI. (thats about $US20 and $US45)
I've gotten back to looking into getting the my VAXstation up and running.
This has gotten me to thinking, how many MIPS is a VUP?

I noticed after I surfed the net, and I do remember it had no video

David, how cheap did you gotten some of these parts through this
mail list? Model 77? I do not know this specs, kindly tell me what
about this? :)
My book does not list this Model 77.

I find this a good story. ;-) The fastest 8088 ever made was 10mhz if
you squint it may hit 12. As far as putting a 386 in a 8088
socket...there is the matter of the 100 or so extra pins.
Oh, if the 25 mhz clock was input to the 8284A then the cpu clock would
be 8.333mhz... almost believable save for the rest of the logic on the xt
board would not generally run that fast without adding waitstates.

Well, Tony, once upon a time I think I was thinking about sending you
some chunks of the 7941/7945 service manual that describe some portion
of the CS/80 protocol used by those devices. I vaguely recall it was
enough of a subset that we came to the conclusion that it wouldn't
help, but if you still think it would be useful send me your postal
address and I will make a trip to the copy shop.
Also it is my understanding that the "hp300" flavors of NetBSD and
OpenBSD contain working code to talk to CS/80 devices. It may be in
the 4.4-Lite BSD release, I think that is where I remember seeing it
first.
The CS/80 command-set reference is one of those manuals that HP Direct
refused to sell me. I had the part number, and the HP Direct folks
told me that it had been withdrawn from offer. Maybe I should give
that another shot; it's been some years ago now.
...
More vague memories: not all HP-IB discs talk CS/80. There was also
a "subset" or "simple" protocol, SS/80. Was that "Amigo"? I can't
remember. I think it is the protocol used by the 91xx discs, and
those are what the Integral seems to recognize.

Don't get pissed off. Look at it as an opportunity. They're in business to
make money; they don't care about preserving history or any goody-two-shoes
thing like that. So offer 'em 5 cents/pound more than the melters if you
get first crack at older systems.
And, contrary to what the media seems to think, continued used is actually
better than recycling something. (Which is why I drive a 38 year old car
rather than a brand new, *recyclable* one that doesn't get any better gas
mileage.)

I had one of those. Had it overclocked to 160mhz, beat the pants of a P100.
I think I paid $150 for the board and chip about a year and a half ago. I
wonder what that'll look like next to the systems 10 years from now?

Hi,
I am in North Carolina and looking for a used pdp-11 to buy. I broke my
teeth in on pdp-11's and vax/vms, and would like to find one to tinker
with. Any help in locating one would be appreciated.
thanks,

Bit more believable. A 25mhz crystal used on the 8284a nets 8.333 at the
processor clock input and that would make a XT-turbo. The problem with
such a speed up is that the peripherals and the ram have to be faster as
well to keep up.
I have a Leading Edge Mod D that I've tried that on and 6mhz(18mhz
crystal) was possible before needing to add wait states for IO and
memory. With one wait for both IO and mem 8mhz was doable. I wasn't
overclocking the cpu as it was a 10mhz V20. I may add at 6mhz the
average 8088 was likely to still be there as they were good for a shade
over 5mhz for the slow parts.
