IMHO the best guide to PET internals is "Programming the PET/CBM" by Raeto West.
Pages and pages of guide to the ROMs (though no commented disassembly, I'm
afraid), comparing different versions, and explaining the bugs in early
versions.
ISTR the PET has 14K (on early PETS, 7 * 2K byte chips) of ROM (except for 4000
series and later) of which roughly 8K is BASIC and 6K is Kernal. In PETs with 4
* 4K chips, the remaining 2K is permanently paged out to make room for I/O
stuff.
And not all that 8K is machine code - you've got tables of reserved words and
addresses and things too.

This weekend, I scored a couple of boards in the Qbus space...
o another Qbus music board (93/D8036) (Anyone happen to have
any programming info on these?)
o a *dual-high* 1 Mbyte memory board (M7506-BC, MSV11-MB)
o an MXV11-B (M7195)
o a DLV11-E
o a DLV11-F
*and*
o An ABLE corp QNIverter
This last one is really interesting as I got to thinking about
whether there was a disk (either from DEC or some third party)
which ran on Qbus and looked like something supported by a
KS10...?
I think RM03s are supported by the KS10, and I *think* I have
an RM03-look-similar somewhere in my apartment (warehouse).
If this is true (and if I can find the controller), I might just
be able to get a less-power-hungry -10 system going in the
near future.
Can anyone help with information of what is available?

Yes, you did... But if I had waited for it to be run in before I
took it, I would have lost out on the chance of getting it. And they
are getting scarce, especially ones in the condition this was...

No, but there are some great scans of "Your Computer" at
http://w1.631.telia.com/~u63104436/
which include some Commodore related stuff, in case your interested.

The Qniverter won't help you with this. The RH11 in your KS10 uses
the Unibus in an 18-bit wide mode (see the Unibus handbook for details
on how the parity bits are chosen to do this), but there are no corresponding
signals on the Q-bus. The Qniverter therefore generates two parity
bits based on the Q-bus 16-bit-wide data bus and subs these in on the
Unibus side.
No 3rd-party Unibus RH11-emulating controller that I ever met does
18-bit-wide data, either.
If you're really serious about using your KS10, there are several
companies (SETASI, in particular) with off-the-shelf Massbus replacement
drive systems. Other companies (like Wilson Labs) make SCSI-to-Massbus
converters. These, IMHO, are the solutions you should be looking at if
you've decided that you don't want RM's and RP's in your computer room
I know several folks running KS10's at home, in one case *two* KS10's
with 4 big Massbus disks and two TU77's. I *did* warn you that you wanted
3-phase power run in before you got your KS10, didn't I ? :-)

Hi,
I am in the process of making a freely available CD of all transputer
programs that are public domain/shareware/GPL. In order to benefit
everyone, I am asking you to donate any programs (no matter how small) as
soon as possible. I want to reach the 650meg mark by the end of this month.
So far I have 300-350megs. Tony, can you send me the schematics for the
B020 as a lot of people are asking me for this. I also have the B020
development kit which I'll send to you. Thanks.

I have a limited amount of Gigilo board info and software that drives it
for PDP-11, RT-11 using I think Micropower Pascal.

Hi,
On my scrounging trip Friday I found a big pile of LS ADM 5 terminals.
The appear to be in good condition. Does anyone need one? What's the
difference between the ADM 5 and the ADM 3A?

Hello.
I have two pdp11/34's (both with keypad/display front panels)
these systems have all the P.C.B.'s etc.. and also (I Think) tape
controller's as well..
and a pdp11/24 in a rack with a pair of RL02 drives and an
emulex sc12 card and smd drive (emulating rk06 and rk07 drives)
this system is running RSTS/E and will boot from any of the
attached drives.
I'm looking for offers and homes for these systems.
if interested please contact me by e-mail.
I'm in North Kent England, so be prepared to either collect, or
I'll hire a van and deliver..
All The Best.
