I've heard the telco variety also called "Champ" connectors. You
used to see a lot of them used to connect desk sets (e.g. 2565) to a
PBX or 1A2 KSUs. Also known as an RJ21 connector.
The 36-pin Centronics as well as the 24-pin GPIB variety are both
members of the Amphenol "Micro ribbon" family. The same 50-position
connector type was used quite a bit for connecting SCSI-I devices.

Is there a 6800 C compilier for CPM or DOS? I've been looking but

Hello all and thanks for the suggestions...
Here's the story so far:
1) Power appears good -- measured correct voltages at power supply header on
motherboard, and at various chips on the motherboard. All seem to be within
specs
2) "Power good" line stays at +5VDC -- I believe this is correct, and
signals that power is indeed good
3) Processor reset line -- at power up, briefly goes to +5VDC, then back to
0VDC and stays at 0VDC -- I don't think it is active low, so this should be
correct, right??
4) Triple-checked configuration switches, and they are correct for the
configuration
5) Clock input to 8088 is dead-on 4.77xxxxxx MHz (my scope shows all the
digits, but I don't remember them :-) -- I think the 4.77MHz is close
enough).
6) One thing that seems odd is that the ADxx (Address/Data) lines seem
"stuck". The scope does not show a waveform, and measuring with a meter
shows some lines right at +5VDC, some at about +4VDC and some at 0VDC.
Perhaps the processor is indeed HALTed???
That's where I am right now ... I'll remeasure the ADxx lines, and post the
full list of values ....
Thanks again for all the suggestions!!!

ISTR that there was also a 100 ?
The 101 was BIG. It was HEAVY. Substantially bigger and heavier than
Laserjet -. It was fast. It was LOUD!
But, it would fit into the back of a Civic hatchback.
I had one sitting around for years. I took it to some of the John Craig
Computer Swaps in San Jose, and siome of the "Northwest" ones in San
Mateo. I could not sell it. Not for $100; not for $50; not for $20
I gave it to City College Of San Francisco in 1983? when I was doing some
part-time teaching there. They stated a value of $1200! so I got a LOT
more off of my taxes than I could have gotten from a sale.
IF they have stopped using it by now, then it was NOT because it was worn
out.

Hi,
I've built the 8" <--> PC adapter described on Dave
Dunfield's site. It works well with an 8" drive from
an
Olivetti M40 system.
But it doesn't work with a Shugart SA851 drive.
Now, after checking the pin description in the SA851
OEM
manual it seems that the SA851 uses pin #22 instead of
pin #12 for READY.
I haven't tried yet whether the adapter works if I
change it for pin #22...
I'm just asking if it's a well known fact that there
appear to be different layouts of the 50pin 8" floppy
connector. I was under the impression that it is quite
standard.
I'll probably add a switch to the adapzer to select
between pin #12 and pin #22.
regards,
chris

It seems that they started using it in the mid 70's. The connector was an
Amphenol 36 pin "micro-ribbon" type, one of the various sizes available. As a
point of reference IEEE-488 (HPIB) standardized on a 24 pin version of the
connector, and the phone company (It was called the Bell System in those days)
used a 50 pin version for their cabling of telephones (25 pair cables as well).
The connectors were pretty common, and worked VERY well, as the wiping
contacts were ultra reliable. In the lab where I was working at the time had
standardized on the 50 pin version for connecting things together (this was in
the mid 60's). So, the connector has been around for quite a while.
Of course, I could comment on their choice of pinouts, being as how they
switched the ground return from one side of the connector to the other about
1/2 way down (what were they thinking!). The problem is that this is now
standard, and nobody wants to change it. (*SIGH*).
In that era of computing (electronics) many connector styles were used. Some
stayed on, and others died. The "D-sub" is another style (DA-15, DB-25, DC-37,
DD-50 (three row!), and DE-9). People fail to understand that the "D" is the
connector style, and the letter following (A-E) is the size of the connector.
When IBM went to the DE-15 connector for VGA, they might have shown some
people, but it still amazes me that the 9-pin connector (properly called a
DE-9) is referred to by an incorrect name (not mentioned here!).

Very clever! I used to get EE trade rags and a regular advertisor
was a socket maker of "correct-a-dip": a daughter-board that you slip
under a chip to correct the pinout or add other parts,
kinda like the Slocket adapters for CPUs.
That's a nice way to do-it-yourself with easy to use, readily available parts

I was pondering that long long ago: using the M1 line to differentiate
instruction fetch from data read/write.
Just one thing: unless it's an embedded system running only from ROM,
the loader needs to re-map data areas into program/executable space.
Before pipelines, pre-fetching and caches,
CPUs accessed RAM with a steady pace and pattern.
I can't be the only one to ponder using a Z80
where the M1 cycles (opcode fetch, refrech) went to ROM
and non M1 cycles went to RAM,
thus allowing other devices to "cycle steal" access to the RAM
without interfering with the CPU execution at all
(unlike DMA which halts the CPU,
or at least all the CPU's bus access).

Build quality? No--I've mentioned that the Panasonic's an industrial-
grade beast. Interfaces? Both have parallel; I've never used the
serial or Appletalk interface on the Panasonic, which doesn't have
USB. The new Brother is head-and-shoulders above the Panasonic
regarding print quality; 1200 dpi vs. 300. Reliability? Hard to say
at this point, although I've owned the predecessor model to the
Brother for a couple of years and never had a problem. Speed? The
Brother is much faster, particularly when rendering graphics; the
halftones are superb.
At this point, a big factor--cost of operation skews things a lot.
Replacement drum and developer cartridges for the Panasonic are
getting pretty dear.

While I might find a NOS drum for the Panasonic on eBay for a good
price, I'm also aware that the shelf life of OPC drums is finite. If
I elect to purchase a remanufactured drum unit, it'll cost me more
than $100 plus shipping. The Brother cost me $40 shipped. I suspect
that for the shipped price of a single Panasonic drum unit, I could
buy three Brothers and stash two of them away for the future.

It wouldn't go to the landfill. I'd disassemble it and send the
metal parts off to recycling and hang onto any interesting
mechanicals and electronics for my hellbox.
I might try freecycling it, but I saw an HP color laser recently go
without a single nibble on the local Freecycle.
Some old things, however well made, seem to be eclipsed by more

Hi,
I'm working on an Z80 MP/M II server for my 8080 CP/M computer and I
have been designing a MMU for it. I thought I'd post it here because it
could be useful to other builders or better still to talk about any
flaws or improvements.
The circuit diagram is here:
http://kaput.homeunix.org/~thrashbarg/MMU.png
Configured like that it is capable of accessing 256kB of RAM with write
protection, or 512kB without write protection by using the 'Mem WE'
output as an address line. The logical address range is divided up into
2kB pages, where those pages can be of any 2kB page in the physical
address range. It's more of a Memory Mapping Unit than a Memory
Management Unit.
MP/M II needs to remain resident in the highest 13kB of RAM so having
the write protection will prevent any runaway processes from crashing
the system. 50kB of RAM can be made available to the running program.
Pages can be duplicated in the logical address range, so if a process
only uses say 4kB of RAM only three pages need to be allocated to it,
two for the program itself and one to fill the rest of memory. There may
be a need to have a table on disk to tell the OS how many pages to
allocate, because a program may use less space on disk than what it
requires in memory.
The Process ID is determined by the 74174 to the left of the SRAM. When
the process changes the 2kB bank making the switch must not change or
the program will be moved and probably crash. In MP/M II this wont be an
issue because the system bank isn't supposed to move.
In this configuration there is a total of 64 processes, 63 if you don't
include the system as a process. When an interrupt occurs it clears the
PID register to zero so the system can be called to service the
interrupt request.
The 74175 to the far left controls the MMU and ROM. The ROM is enabled
after a reset and the MMU is disabled. This is done by deactivating the
left CS of the RAM and connecting the upper address bits of the CPU
directly to memory. The remaining two or three address lines should be
tied high with resistors, or even connected to the 74LS244 with those
inputs tied to +5 or Ground.
The tricky element is the 2kB dual port SRAM. I found two of them on an
old arcade game board. This lets the CPU program the mapping of memory
without having to implement a messy multiplexing system.
To program a bank an 11-bit address is loaded into ports F9h and FAh,
then the desired bank is programmed to port F8h. The lowest 5 bits of
the address selects the desired 2kB page the CPU will access and the
remaining 6 digits determine the PID. Maybe they should be split up so
one port selects the page and the other selects the PID.
Maybe someone can use this? I haven't looked deeply into the MP/M II
XIOS requirements so I may have left something out that it needs so is
anyone familiar with the XIOS?
Cheers,
Alexis.
Building on previous posts:
Standalone backup can be installed on the system drive, it gets
installed as [.SYSE] and is then started by:
>>> B /R5=E0000000 DKA300
Any disks it needs to use must be ready before it goes looking for them
during initialisation.
The one off creation of the standalone backup kit (i.e. [.SYSE]) goes
something like:
$set def sys$update
$@stabackit
[Ref VMS System Manager's Manual]
Standalone backup has some limitations, e.g. at ~V5.5 it only supports a
cluster size of 1; i.e. it only supports disks up to 1 Gby. This means
that you can't use it with RZ27/28/29 StorageWorks (1/2/4/8/.. Gby)
disks.
On a machine with a SCSI bus and with spare scsi disks to hand my
preference would be to write the backup to another blank scsi disk as a
save set, and then to archive the backup on modern hardware. The save
set condenses the disk to it's minimal file size, and on restore you get
a "fresh" copy with contiguous files. The basic incantation is:
$init DKA200 volnam /nohigh
$backup/image/verify DKA300: DKA200:filename.sav/save
It's best practice to fix up any lint on the disk prior to backing up /
archiving it, i.e. to resolve any block allocation / file index
inconcistencies:
$analyse/disk DKA300: -- generates a list of issues
$analyse/disk/repair DKA300: -- lists and fixes any issues
$analyse/disk/read DKA300: -- reads all the blocks and tells you which
ones have irrecoverable parity errors
With three spindles on a system you can produce a compact copy of a disk
image, with the file index at the beginning rather than the centre of
the disk. One spindle runs the system and backup, another disk (which
could also be the system disk) has a saveset copy of the imaged disk on
it, the final disk will be initialised and have the saveset written to
it.
$initialise dkb000 /index=beginning/nohighwater
$mou/foreign dkb000:
$backup/image/verify/noinitialise dka200:filename.sav/save dkb000:
The reason for doing this used to be to produce the smallest possible
"necessary" disk image for burning on a CD or whatever. Nowadays, I
would probably copy the entire disk - GigaBytes are cheap, ensuring you
have copied to the HWM can be expensive. Obviously, a live disk volume
should have the file index in its default location at the centre of the
disk.
IIRC there are/were some (free) SalesWare utilities which permit
Files-11 disks to be mounted on XP and read. This would provide a much
neater (and safer) way of eliciting the .sav (save set) file for
archival on a PC than croping an image at it's high water mark.
However, dd of the entire disk containing the savesets may be even
better.

On that Diablo dot-matrix, it wouldn't just wake him up, it'd
probably send him to the ER with some fractures. I think the
carriage servo was run from either 48 or 24VDC. I've still got a
spare from a Durango printer (same design people). It's basically a
48v Litton Clifton PM DC motor with an attached encoder. I was told
that it cost more than the rest of the mechanicals on the printer
combined.
The other odd thing with the Diablo was that it used several early
Rockwell MPUs (at least more than one). PPS-8 or PPS-4, perhaps?
I remember seeing and using a really oddball printer in the early
70's from Singer-Friden. It used a disc type element oriented
vertically and perpendicular to the paper surface, a leadscrew for
advancing the carriage and a big honking spring for carriage return.
The type element was inked by means of a felt pad (no ribbon) and
tended to leave nice vertical ink stains on the paper when not
printing. Very similar to that used on the Singer-Friden 115x
calculators, but scaled up for 14" tractor-feed paper:
http://www.oldcalculatormuseum.com/friden1152.html
When the project shut down, the call came down for the lot to be
scrapped, but a co-worker arranged for one to "disappear" off the
loading dock. I don't know if he ever pressed it into use.

Chuck
I don't have the message archives, but I don't think that anyone
mentioned the Cypress CY22016L NVSRAM using QuantumTrap technology.
Pretty cool stuff; very fast SRAM backed by NV RAM; at power-up, the
SRAM is loaded from the nonvolatile store; at power-down, it's
written (optionally and probably not needed for this application).
The "juice" for the optional write-back on power-down is guaranteed
by at least a 68 uF capacitor.
The SRAM has access times of 25, 35 or 45 nsec. and unlimited writes.
The NV RAM is guaranteed for 1,000,000 writes.
It's a 5V part and comes in a 28-pin SOIC, so it'd fit nicely on a
small PCB that'd fit the outline of a 24 pin PDIP.
Here's the datasheet:
http://download.cypress.com.edgesuite.net/design_resources/datasheets/
contents/cy22e016l_8.pdf
This family comes in sizes ranging from the 2Kx8 just mentioned to a
512Kx8/256Kx16 item.

There is no way that I would want to own and operate a CDC 501 (drum)
or 512 (train) printer. Changing the ribbon, even with the provided
gloves was a messy job (who knows if ribbons could even be found
anymore), and when one of those ribbons got tangled up in the 512
type train, it was an hours-long incredibly messy job digging the
bits and pieces out. Inevitably, you'd find that you'd assembled the
type train with a character swapped here and there.
The old drum printers tended to suffer from the wobbly line syndrome,
where characters would be displaced from a straight line in a
vertical direction. On the other hand, the train printers, while
creating nice straight lines, would often displace characters in a
horizontal direction. The former was far more noticeable than the
latter.
In the mid 70's, my lusted after personal printer was one of
aftermarket Teletype model 40(?) band printers. About 300 lpm, I
think and basically a tabletop unit, usually sold in an acoustic
enclosure. Print quality was pretty good (upper- and lowercase),
unless you printed a lot of dumps, whereupon the '0' would get kind
of fuzzy after awhile. I still have a copy of the OEM manual for one
of these if anyone's interested.
I briefly had a Diablo dot-matrix printer--the carriage servo could
crush your hand if you were stupid enough to put it in the wrong
spot. An incredibly noisy screaming demon of a boat anchor. I got
rid of it while I still had my hearing.
Cheers,

It isn't difficult. But as anyone who knows, you must collect IMPACT printers!
None of this silly laser stuff, or even worse an ink-spitter (they actually
has ones that did!). Me my collection has a few:
An older wide Decwriter (LA120?)
A narrow DecWriter (LA30) that I modified to do upper and lower case.
A nice Centronics 300 LPM band printer.
A couple of Daisy-Wheel printers. Some actually work. The Qumes; I have a
Sprint3/4 (depending upon the boards) with a keyboard, a Sprint 5 (RO). I also
have a couple of Diablo ones that use the metal wheels.
Then there are the OTHER ones:
A couple of Noisy-90's (Silent 700s) of various types (some portable, some
not).
No to be true printer collector, one must have an impact printer somewhere.
Even a teletype would do in a pinch (somewhere I've got an ASR33 stashed).
On topic stuff: I've got some prints of the Qume printers somewhere if anyone
is interested. They are pretty simple to interface. I used a MC6821 PIA and a
few chips. Pretty easy.
Good luck to all

Hi,
Does anyone have some Wave Mate Bullet boot disks? I have one of these
computers and I think it works but have no boot disks.
The disks are 5.25" soft sector so all I need is an ImageDisk or TeleDisk
image of your boot disk and not a physical copy.
If your Wave Mate Bullet is using 8" disks those might work too. However,
it would be better if you could attach a 5.25" drive and format and SYSGEN
the disk, copy some CP/M files to it and make an image of it.
The Wave Mate Bullet says "Microcomputer Rev C" on the motherboard.
Much appreciation in advance if anyone could help me out. Thank you!

Hi Folks,
I just got off the phone with a very nice gentlemen from Amersham
who's trying to get an old PC program (on 3.5" media) going on his
modern PC system. He's run into one of the copy-protection schemes
that worked fine under MS-DOS but not under 2K or XP. I suspect that
one of the copy-protection-defeating programs may be just what he
needs.
Any help I can offer will be at a distance of 5000 miles. I was
wondering if anyone on that side of the Atlantic might be willing to
help out.
Drop me a line if you're interested and I'll put you in touch.
Thanks much,
Chuck
All:
I need to clear space in my shop and refocus my projects a bit. So, I?d
like to divest my Tandy 2000. I bought it last year and refurbed it with a
new 20mb hard drive and a second floppy drive. It has the color graphics
board, 640k of RAM, a CM-1 monitor, VM-1 monitor, a few spare parts,
software and books (in various conditions). The case is gleaming white ? the
person I got it from must have kept it in the dark because there?s no
fading/yellowing at all.
I was going to use this for an emulation project but realistically, I?m
not going to get to it.
Contact me off-list if interested. Shipping would be from 11791 (Long
Island, NY) in three or four boxes I?m guessing.
