Everything must go in a few days, otherwise will be thrown away. Some things
are too small for me to take the trouble to ship individually, but will ship
two or more; they are marked "NS". I will ship to the people who ask for the
most items at a time. Prices are 1.2*shipping. Some classic stuff, some more
modern. Something for everyone, please look through entire list. Please note
also that some disks may have rotted, and I can't be responsible, but to the

<Just my observation, of course. Few processors would actually run that fas
<for long, but those 8 MHz parts would do it for a little while if you kept
<them cold.
I've been running them at 8 and 10 mhz for years. The cmos parts do run
cooler though even at 10mhz. To get real perfomance out of them (under CPM)
you need to have a caching bios or the disk system will definately be the
bottleneck. Also DMA is a must though the zilog DMA part never hit more
than 6mhz the 8237-5 worked just as well and didn't have to run lockstep
with the cpu.
my 10mhz machine is on s100 and the CPU is not running the bios for disk
IO thats a 4mhz z80 with DMA the the main system ram. the 4mhz cpu runs
the hard disk and caches it (it actually pushes a teltek HDCTC as it's slow
MFM) so the caching operation is invisible to the main cpu. CPM screams on
that crate. There is an 8085 configured to do the same for the floppies and
that caches at the track/cylinder level so the initial read is a bit slow
but after that it's much better as the 32k LRU cache really helps.
To date the fastest z80 system I've run (no waits) is 10mhz... I have a
z180 that clocks faster but the dram is wait state so the effective speed
is slightly less than 10mhz.

Sounds like a twin, Wayne!

I have one of these units, I think. Mine is called the "745 Portable,"
TI Part No. 0983801-0003 and is about the size of an old Remington
portable typewriter. Looks like an early 1970s model with a standard
phone coupler and a 15-pin connector with an 8/7 pinout. Mine is in
taupe colored plastic with a cover and four plastic connectors similar
to the ones used with Osborne and Kaypro keyboards. The quality of
construction is quite high and the keyboard has a nice feel. There is
a picture of one shown at VCF 1.0 at:
http://www.rdrop.com/~jimw/vcf-09.jpg
Is it the same unit, Don?

Mac is a Mac LC, the card has no identifying marks other than
it's from Apple and it's a "Apple IIe Card". It has a real funny connector
on it. Any ideas?
-------
I did get far enough along with some 55ns SRAMS in four 16K boards, to see
clearly that running the processor at 12 MHz with floppies isn't nearly as
good as running it at 4 MHz with a decent hard disk. The difference between
my 8 MB ramdisk and my then 40 MB (formatted) HDD, was barely noticable,
while both were considerably faster than the hot-rodded CPU with fast RAM.
Just my observation, of course. Few processors would actually run that fast
for long, but those 8 MHz parts would do it for a little while if you kept
them cold.

I agree. ;) However I did check zilog and the part is a new beast and does
offer potential for some hot performance. Little things like 24bit linear
address and an accumulate/multiply engine. With those goodies added yep,
beats 180s182. The z80 has plenty of room to grow and unlike the
8080-->8088 transistion they learned from the z8000... it's z80 code
compatable!
This is one I'd like to play with... can you imagine CPM with 16mb ram
at 30+mhz?

I have no idea what they are work --- but would love to buy one..... any
idea what you are looking for??? I'm a gread student and have collected a
working pdp-8 and vaxstation --- would love at add a pdp 11. Please let me
know how much you were looking to get

I don't need the card punch but I certainly agree with those sentiments...
I also thought that there would be alot more trading/swapping going on in
this community... I do however appreciate the information flow and have
learned and been entertained often.
