I changed the microcode in my 2901-based  ETH Lilith such that it can use an 
ATA-harddisk instead of the unobtainium SD-120 Mididisk.
It works in my Lilith emulator Emulith, sadly the real Lilith is still down 
with other issues so it has not been tested with the real hardware.



What about the coding tools?  ADASM?  Looks long gone, how do you do microcode 
today?




As is to be expected the Lilith came with its own modula-2 based coding tool. I 
wipped up another one in C.
Note that this is a lilith-microcode assembler, as it covers more than just the 
2901.
 I would expect this to be the case for other machines as well.

All tools & microcode and emulators are on my FTP site

I would be interested in any hardware projects, stories (or even in the FPGA, I 
hear its a popular thing to copy);


I read all of Donnamaies pages, and planing to hook up, breadboard the eval 
kit, perhaps reproduce the PCB if you guys are interested.

If I forget the soldering iron, can anyone show me an example on a Xilinx

Re: Lisa Source Code

[Richard Cini via cctalk]

That is really awesome. Not being deep into the Lisa platform, 
I wonder if the sources to the Toolbox ROM (or equivalent) was also recovered 
and how different the sources are to those already out there for the original 
Mac.

RE: Argh--my old faithful HP16C is failing!

[CuriousMarc via cctalk]

Thanks. This is one ugly duckling. I know why I didn't keep it! But it seems to 
be functional. Stick to the 15C mentioned before if you don't need the 
programmer's features.

I can't find anywhere in the github repo that the version number was not
updated to 0.35.  (Just now updated to 0.36.)

But anyway, it compiles happily with two modifications in tumble_pbm.c:

I'm happy to accept pull requests.

The HAVE_BOOL would probably be fine, but I'm not going to change the
include as it would then fail to build on Fedora and RHEL.

Re: RT-11 idle light pattern

[Paul Koning via cctalk]

It's been a standard feature of RT-11 FB since it first came out (in V2).  You 
need to set the select switch to display the "Display" register (unlike most 
other OS idle patterns which rely on the data path display showing R0 when at a 
WAIT instruction.

Here's what it looked like in V2.0 rmonfb.mac:

; "A SOURCE OF INNOCENT MERRIMENT!"
;   - W.S. GILBERT, "MIKADO"
; "DID NOTHING IN PARTICULAR, AND DID IT VERY WELL"
;   - W.S. GILBERT, "IOLANTHE"
; "TO BE IDLE IS THE ULTIMATE PURPOSE OF THE BUSY"
;   - SAMUEL JOHNSON, "THE IDLER"

10$:DEC (PC)+   ;THE RT-11 LIGHTS ROUTINE!

Re: RT-11 idle light pattern

[william degnan via cctalk]

Do you have an octal or asm listing for the part of the code with the
migrating bar effect?   This would be a good practice / test for me to try
on my RT 11 system.  Merry Christmas
