KIM-1 Simulator 1.3.0 -> 1.3.4

KIM-1 Simulator 1.3.x adds the improvements from the 1.2.x branch to the V1.1.8 branch.

NEw improvements also: bundled with the also recently updated Convert 8 bit Hex formats program and the SST switch now turns on the built-in debugger!
1.3.1 Adds refresh of K-1008 memory with File/tapeload and debugger refresh.
1.3.2 Load C header image files into K-1008 video display, and command line utility to convert C header file to K-1008 binary
1.3.3 Adds a more realistic aspect ratio variant of the K-1008 display besides the simpler and therefore faster ones.
V 1.3.4 August 31 Read text file to console improved, improved K-1008 settings

Have fun with this release and as always: keep me posted of wishes and bugs.

You may ask, but this will never be more than a simulation and not a real KIM-1 emulator, many First Book of KIM programs that manipulate the LED displays will not work in this simulator architecture. TTY programs work well. Use the debugger!

Convert8bit hex V2.4

The Convert 8bit hex formats utility has reached version 2.4.

Bugs fixed:
– one off papertape save fixed
– KIM tape format more robust
New save format: Define Byte. assembler formatted .byte $XY, prefix text user defined.

The last book of KIM

On his blog Nils has posted for download ‘The last book of KIM’:

Ich habe in letzter Zeit Energie in dieses kleine (auf Deutsch geschriebene) Heftchen gelegt.

Es ist allen Enthusiasten gewidmet, denen, die es werden wollen, und denjenigen, die es waren. Es soll einen in der Computerhistorie bislang unterrepräsentierten Mikrocomputer ins rechte Licht rücken und seine Rolle bei der Entwicklung hin zum modernen Heimcomputer beschreiben.

Viel Spass

Original KIM-1 ROMs reproduced

I have two sets of KIM-1 ROMs. One set is the original KIM-1 dump by Dwight Elvey, in which the filler bytes (unused locations in the ROM) are filled with $00.
Alas the dumps by Dwight have a couple of bit errors and the NMI vector is wrong.

The other set is the result of assembling the source in which the assembler used $FF for the filler bytes. It makes sense to use $FF, since EPROMs can be programmed byte for byte ‘1’ later to ‘0’s.
Functionally the filler byte is irrelevant, so I present here the ROMs with filler byte 00 (corrected Dwight original KIM-1 dumps) and filler byte FF (assembly result).

6530-002 $1C00-$1FFF, filler bytes $FF 6530-002 ROM
6530-003 $1800-$1BFF, filler bytes $FF 6530-003 ROM

6530-002 $1C00-$1FFF, filler bytes $00 6530-002 ROM
6530-003 $1800-$1BFF, filler bytes $00 6530-003 ROM

Small update to KB-9 V1.2 and KB-6 V1.2

Small update to KB-9 V1.2 and KB-6 V1.2: the NULL command is back, to ensure binary compatible tokenized saved Basic programs.
Now the USR location is the same in KB-9 V1.1 and V1.2, 2040 and 2041 (see Nils’ blog KIM-1 Basic and the use of assembler subroutines – netzherpes).

In KB-6 V1.2 it is 8254, 8255.
