If it has ISA bus either JADE, JAMCO or JDR I forget which, sells an
ISA-8 bit to standard IDE adaptor. What makes it nice is it has bios
support on it. Acculogic made one too at lone time.

Keep in mind, these things were in vogue back in the days when the *users*
actually *expected* to get the schematics! My how times have changed . . .

The Z-67 is a rare item indeed. I missed one in 1988. That's the last time
I ever saw one offered for sale (and it was *just the interface*). I don't
know anybody running one of these . . .
My Z-89 dosen't run anymore. Too many years of disuse, I guess.

On a PC maybe, but nothing is available for a Apple //.

Hi All:
I'm hoping someone might have spare copies of DR PL/I-86 (CPM86)
documents (Reference Manual & Programmer's Manual).
I have some good IBM docs but I need platform specific.
I don't think I need any 3rd part PL/I manuals yet, but if anyone has
some and would like to email the list to me, I'll certainly browse with
intent to buy.
I'm willing to pay a reasonable proce plus shipping, of course, for any
books.
I'm also looking for original PL/I programs for microcomputer platforms
if anyone has some collecting dust.
Thanks,
Mike Allison
I picked up a Grid wall adapter model 39008, 17VDC 1.25A center +,
available for shipping cost if anybody needs it.(Sacramento CA area) I
don't know what it fits.

Because I was, and currently am, using Netscape which I have access to
on Saturdays and Tuesdays. BTW, I will be going away for a while. I'm
almost too embarassed to ask this, but what is the listserv adress to
unsubscribe?

I just got an Amstrad ppc 640, and am starting to realise how much I really
wish this thing had a hard disk - even a little one. Is there ANY sort of
hard disk solution that will plug into a 720k 3.5inch floppy controller?
Ideally it would come out the other end in IDE, and I could put one of those
little 1.8 inch 20 meg IDE drives in the thing. Speed is not a huge concern,
since this is a 4.77mhz XT class machine.
Also, if anyone has a wrecked ppc 512 or 640 that has a good back case section-
the bottom part of the main body that the handle is screwed to (and the handle)
I'd be very interested in buying it. Mine appears to have gotten squooshed in
shipping and had the handle torn off, and I'm lothe to trust epoxied plastic
to hold a 14+ pound computer.
