Correct... and with 5 sockets, there would be one left over
for either the EIS/FIS option or WCS, not both.

Actually, I've seen the dual microm used on both 11/03s and
on 11/2s, as well as on the PDT (I have a couple of those
which have been so modified). The 3007/3010 chips are
combined into one dual microm. This would allow boards
with only 4 sockets (like the PDT) to add EIS/FIS.
>On the 11/23 and 11/24, some of the chips were also on dual-chip

The FPU chip for the 11/23,24 was a dual carrier chip. The
CIS option was a hex-carrier chip. It had 6 of those small
gold chips on it, and spanned two sockets of the 11/23[+]
board. I don't know if it could go on the 11/24. (I have a
KDF11-B with one of these chips on it).

If someone does, I need a dump of the contents of the

And if we ever have one, well, I know of ClassicCmpers in Kansas, Missouri,

I just realized that my reply to Jerome's inquiry about the
LSI-11 module with five chips was probably wrong. IIRC, the
LSI-11 chip set consists of the control chip, data chip, and
two MICROMs for the base instruction set. The EIS/FIS (KEV11)
is a single additional MICROM. So the original quad-height
LSI-11 module would have four 40-pin chips without the EIS/FIS,
or five with.
Was it the LSI-11/2 half-height module that sometimes used
a hybrid with two MICROMs? If so, it was probably the two
microms that implemented the standard instruction set, in
order to leave a socket open for the KEV11.
On the 11/23 and 11/24, some of the chips were also on dual-chip
hybrids.

This'd be an incentive to get the VAX-11/730 running again. That'd
make a nice, compact display if I don't kill myself trying to move
it. Or if I could squeeze more than 2MB in along with a UDA50 and

Well, a while ago I was soliciting ns32k hardware of all sorts and
while the Symmetric was mentioned as an example, no one was offering
a unit for sale, trade, or otherwise. I don't recall anyone having
production numbers, but "few" seems appropriate...
Darned shame, it's a very fine looking box. I'd love to have one, as
I'm sure would at least a few others.

PS - Thanks to all who responded to that earlier thread, esp. David

I'm trying to help some guys outfit TI-99/4As with 360K
drives. A year or so ago, they were still available from
some of the surplus dealers I know about, but they seem
to have disappeared.
Does anyone have a line on supplies of 360K drives? The
only ones I find via web search are $25, which seems a
bit much for a once-ubiquitous drive that is now a little
obsolete.
Mark -
Saw your note on classiccmp.org re the Dynalogic Hyperion. I have several of these machines as well as some diagrams and parts lists for them. Two of them have a problem in their video circuits such that their screens show nothing nor is there a signal out of the external monitor RCA plug, yet the computer will otherwise continue to function normally. I have been looking for some guidance on how to track the fault down and fix it but have so far had no success. Any thoughts?

If you're one of those people who wants a PDP-8 but can't find one, don't
despair - you can always build your own! The SBC6120 is a complete PDP-8
built around the venerable Harris HM6120 CPU and modern programmable logic
devices. All parts used except the 6120 are contemporary, easily available
devices.
The entire system fits on a PC board 6.2" by 4.2" and has approximately the
same footprint as a 3.5" hard disk. The SBC6120 has an IDE disk interface,
an optional 2Mb non-volatile RAM disk (that's as big as an RK05!), and a true
KL8/E compatible console terminal interface. OS/8 device handlers are
available for the IDE and RAM disks, and the system will run standard
OS/8 V3D. There's even an expansion bus so you can design and build your
own daughter cards to plug into it.
To find out more, visit the SBC6120 web page at
http://www.SpareTimeGizmos.com/Hardware/SBC6120-2.htm
I've recently had two requests to buy SBC6120 PC boards. These are four
layer boards with plated holes and are quite expensive in quantity one or two,
but the price falls per piece falls dramatically for quantities as small as
four or six. I'd like to find a few other people who would be interested in
building their own SBC6120 and going in together on a PCB order. The price
for a SBC6120 PC board would be something like:
Two boards ==> $100 per board
Four " ==> $60 per board
Six " ==> $45 per board
Ten " ==> $36 per board
I also have about four spare 6120 chips, which I'm willing to sell at my
cost of $50 each. Believe it or not, it is still possible to buy new old
stock 6120s, at $50 each, with a minimum order of ten (!!), but if enough
people want SBC6120s we could always go this route.
If you're interested, please write to me at bob(a)jfcl.com.

Wayne Stewart did a PDF conversion--not just a scan--of
the manual for the Apple II Programmers Aid ROM. There
are a few typographical errors but it is very good.
It is about 278KB. E-mail me if you want a copy.
The empty ROM socket in the Apple II at addresses $D800-$DFFF
never had an official Apple ROM but there were some third party
ROMs such as the Inspector and the Senior PROM. In the Integer
BASIC disk file on the DOS 3.3 system masters that area is
filled with the Applesoft BASIC code from the same range of
addresses.

...At least that it what I called the little challenge I gave myself
tonight. I had my IBM 5155 (aka the Portable PC) opened up in order
to test some MFM hard drives (a task that failed miserably because
the drive controller couldn't handle the ST-251 drives). As often
happens, I got sidetracked and started pondering the very limited
clearance that most of the slots in the 5155 have, due to the hard
drive and floppy drive taking up so much space.
I found myself thinking that it would be a shame to waste so many
otherwise useful slots; and I subsequently started plotting out what
could fit in there.
Here is a picture of the (almost) final results...
I say almost, because the one full-clearance slot that is still empty
has a card slated to go in it, a 3Com EtherLink II. I just have to
remember where I put the thing. The last slot is currently being
used up by the parallel and joystick connectors that are coming off
the IO card in the first slot. I may go ahead and remove those
connectors and use that slot for a dual joystick controller card that
I have around here somewhere.
FWIW, here is what Crysta is now equipped with...
Slot 0: - IO Card (RAM, Serial, Parallel, Joystick)
Slot 1: - Floppy Controller
Slot 2: - Sound Card - Covox SoundMaster II
Slot 3: - Reserved for NIC (3Com EtherLink II-TP)
Slot 4: - CGA Adapter - DFI 2002
Slot 5: - HDC - WD1002A-WX1
Slot 6: - SCSI - NCS-250-SC
Slot 7: - Reserved for Suncom Joystick Card
So, anyone else here ever maxed out a 5155 before? Great thing about
having SCSI capability is that being limited to a 20MB MFM hard drive
is no longer a major concern. If I need more drive space, all I have
to do now is hang an external SCSI drive or two or three off the
system.
Also, while I was working on Crysta, I was thinking that this might
actually be a good candidate for the control terminal for the
Cromemco System Two; at least until I can get an actual Cromemco
Smart Terminal...
Anyway, enough random nattering from me for tonight. Time to get the
clutter cleared up and go get some sleep.

I know this is a bit OT, becuase it's not really computer related, but the
hardware is at least 23 years old, so that's my excuse for posting to the
list...
I've got a 35mW HeNe Laser + Power supply that I picked up today for next
to nothing. It seems to be having some problems - the laser (somtimes)
blinks a few times when I first turn it on, and then stops. From the
sound of the power supply it's either a loose connection (which I doubt
after opening it up and taking a good look around) or there's a problem
with the power supply.
Now, I've never really worked on a HV power supply before, and I'm trying
to be careful when I play with things. First off, does anyone have a
general idea of what sized dummy load ("resisitor") I should try haning
off of the HV output to properly load it? I noticed that the laser tube
has 3x27kohm resistors in series, would a couple watt approx 81kohm
resistor be a good idea?
Also, does anyone have an idea for a failure mode to look for? I've got
an O'scope, dmm, and various other tools at my disposal, but no
'authentic' HV test/mesurement gear.
I'm just looking for general guidelines.
Thanks!

Hi --
Having doctored up one faulty drive and replaced the other, my TRS80 Model
3 is now ready for action. It fires right up and will boot several
different Model 3 OSes. The documentation I received with the unit
contains a lot of detail, but it does not describe all of the i/o
connectors on the rear of the unit.
The ones which I can identify from the docs are a female DIN connector for
tape i/o and a female DB25 for serial i/o. The docs also describe the
parallel port as a 34-pin card-edge connector (which I suppose needs a
Tandy-specific cable to attach to a printer), but the problem is that there
are *two* of these 34-pin connectors on the rear of the system, as well as
a 50-pin card-edge connector.
Can anyone familiar with this system help me out with details regarding
these connectors?

Hello all,
I just a couple of days ago picked up a VAX 11/750. This machine has
been stored
in a damp shed for ten years or so, has had mice living in it, and the
usual assortment
of spiders, etc. After bringing it home, I immediately wrote down what
cards were in
what slots, etc, before dismantling the system for cleaning. Everything
is out of the
chassis, with the exception of the console cable and the wires that
connect the backplane
to the control panel and TU58 tape drive. I'm in the process of cleaning
all the components,
but am in search of some advice on this process, especially the power
supply. How long
should I let the power supply dry out from its prior damp condition, and
what should
I do to bring it up for testing without risking damage to other
components? I wish to
do this methodically and carefully.
Thanks Much!
John Willis
