While sorting stuff today, I came across the Dyson software for testing
floppies. We used to use this for testing many of the early full size
and half height 5 1/4 floppies. Dated 1985, 5 disks and manual in a
plastic wallet binder.
I was going to put it up on eBay but realised that maybe someone on the
list would get more benefit from it. Would rather see it go to a good
home than make a dollar or two from it. Let me know.

I've been getting more stuff ready for eBay. Today, I opened a box of
Apple II books and software. The box seems to be one I packed in 1986
when I moved to California. I have no idea if this stuff is worth the
effort to list it and then have to handle it. Could someone on the list
give me some advice? If I send you a list of what is there, could you
tell me whether it's worth the trouble?
Please reply off list to: bpettit at ix.netcom.com
Thanks for your help,
Billy
I am about to obtain a MicroVax model 655QS-B2...
I was hoping someone could tell me about this machine, and a good
source for documentation and/or information...I know it does not have
a power cord with it, but don't even know what kind of power cord it
takes...
If anyone is willing to help me with a few more questions, I would
appreciate it, as I am very new to the Classic Computing area (except
for some old C-64 and 128 stuff)
Thanks

No, their characteristics are all wrong. The Cores I refer to are
large by a fact or 15 to as much as 100 time that of cores used for
memories.

The past day cores were very optimized material and have not seen
any improvement.
As to making a corestore today it's still possible but the small
cores needed to attain a 1-2uS cycles time are not common.

Tonight, Friday May 13th, the Tonight Show will feature a message

a Morse code team.
The Morse code team will consist of Chip Margelli, K7JA and Ken Miller,
K6CTW. The Tonight Show people called the store yesterday to see if we could
come up with two fast Morse operators. Chip and Ken does a lot of contests
and DXpeditions. Joe Drago, props manager for the show is
KF6OCP.

Evan speaking again: am I just out of the loop on radio collector terms --
do they have something called the "Tonight Show" -- or do ya'll expect they

Hi Folks,
Does anyone know of a loading dock that Norm Aleks and I
could use for a few hours next Thursday? We're doing
a computer rescue and will be able to save significant
shipping bucks if we can UHaul the stuff to a loading
dock and wait with it for pickup by a common carrier.
We're looking for something southwest of Boston,
Norwood area.
Could you email directly if you have any idea?
We'd much appreciate it.
Thanks
Brian

I do have a PCdos compatable asm that is pretty neat but for little stuff
the eyeball does it fast enough. ;)
One day when time permits a RS08 equivelent will be made for the 8f
and I'll start running real software.

I have no PDP-8a. I do have three 6120 based systems, two DECmateIII
and a homebrew using the chip. The 6120 is the second generation of the
6100 PDP-8 in CMOS. It adds EMA and stacks via IOTs in hardware. Runs
OS/278 flavor of OS/8 well enough.

MV3900 SBB:KA655-AA 16MB 240V
Looks like a MicroVax, having a KA655 CPU, 16MB RAM, running on 240V,
about 1998 vintage.
And a picture...
http://hampage.hu/vax/e_1989.html
Looks like a nice, reasonably modern fast Vax in a digestable size. But
you'll have to do something about the 240V.
