I know that it is a "one-shot". What does that
mean? The pinouts in the Chip Directory are
no help. Several seem to be involved in the
DEPOSIT logic on the IMSAI front panel.
Also, I can't quite figure out what the logic
table for the 74107 is trying to say.
Thanks,
Bill
Hey folks. Anybody have any info on what software is required to run an HP
64110 processor emulator with various (z80, 68000, etc) emulation pods?
Anybody here ever use one?

I *think* I saw a z-80 and a 68000 CPU in it. We didn't havve any tools
and couldn't get all the way into it.

They might be but I *thought* they were larger. They are shielded so
maybe they just looked that way. They're LONG and seem to be made to go to
something outside of the cabinet.
Mine has an
>Adaptec scsi card and two enormous HD's in it (I think 10 meg apiece).
It has a large card mounted next to the hard drive. The card looks like
it converts SCSI to MFM for the hard drive and an interface for the 8"
floppy drive. There is a FH 5 1/4" hard drive in it that appears to have a
MFM interface. No idea what size drive it is.
I didn't get it but I can if someone wants it. I may be going back there
today or in the next couple of days so left me know ASAP.

I just found a small box containing 6 8" DEC floppies labeled
RT-11 V5.2 BIN RX02
Part numbers BA-P727E-BC through BA-P732E-BC
The box (apparently) had not been opened, but the condition of the disks
is
unknown.
Anybody interested?

Hi, Marvin.
As Tony said, option 31 is not related to the 31 calculators. In fact it is the
multiple pen option for the 4662 - an 8-pen semicircular carousel.
How technical is this manual? I have some manuals, somewhere, I think, but I
need to know the part number for the little gear that bolts onto the motor
spindle in the option 31. (This drives a toothed belt which in turn drives the
carousel).
This gear on mine is in three pieces (metal hub + two parts of plastic gear). I
tried glueing back together, but the thing dropped a tooth on the belt just
often enough to be annoying. I suppose I can try again, reassembling the gear
more carefully, and tensioning the belt more accurately, but I'd like a new gear
anyway...
Philip.
EMM SEMI made a number of odd-shaped (as compared with more conventional
configurations of the time) staticc memories back in the late '70's -early
'80's. These don't particularly ring a bell, though the 256x8 seems to
sound about right. I haven't seen any literature lately. perhaps someone
with a recent IC master will have more.

Cameron,
I can send you the Source Code for MicroBasic (An integer basic) written for
the 6800 in 1975.
The assembler memnomics are basicly the same, it shouldn't be too big a
stretch to convert to the 6502
(Which I always intended to do 24 years ago when I wrote it)
