6530 Replacement
================
Replaces the 6530 ICs found on early revision Allied Leisure pinball machines.
The 6530 and 6532 are very close in functionality.
Nearly the same timer, 2 8 bit I/O ports, RAM.
With an external ROM and some clever addressing logic many 6530’s have been replaced with a 6532.
Here some examples:
Design by Dwight Elvey
Besides connecting a 6530 to a 6502 system, as is described in the other pages, a simple and effective test and ROM dump can be done with the wonderful Backbit Chiptester Pro V2.
This device van help detect problems with a large number of older ICs. And dump the contents of ROMs Especially the 65XX tests and ROM dumping have served me very well, e.g. the KIM-5 ROMs 6540 were read out with this device.
It can also check the 6530 RRIOT. My collection of 6530s has the KIM -002 and -003 and those tested fine. Initially the other 6530s tested with problems at Port 2 (the PB0-7 I/O pins).
Now port 2 is special since the mask programming allows to choose between CS1 and CS2 or PB5 and PB6.
The support of the Chiptester Pro is excellent and after some discussions with version CTPro-5.0.5 all 6530’s test fine. Alas the ceramic 6530-002 4576 has a defective ROM.
I have tested the following 6530’s
– 2x MOS MPS6530 002 0880 4576
– 1x MOS MPS 6530-003 0680
– 1MOS 6530-004 2576 and 5x SY6530-004 7935D
– 2x MOS 6530-005 3676 2876 and 1x R6530-005P 8114
– 1xR6530P 3004 -11 7925
– 3x MOS MPS6530 024 2081
and all ROM dumps were fine, confirming the ROM dumps I have were indeed he correct ROM dumps.

Dave McMurtrie (Commodore History) has published a video showing how he dumped the ROM image of a 6530-009 (used in Applied Leisure devices)
By using the breadboard extension and the Corsham Clone 5 he wired the 6530-009 into the memory of the 6502, by interpreting the (general) 6530 datasheet as shown in the next screenshots.
The resulting dump of the ROM is identical to the 6530-009 of the Allied Leisure
A 6530 IC is to be used in a 6502 computer as standard 65XX peripheral.
Two of the tests on the next pages are breadboard tests on a KIM-1 (clone)>
The first test is the simplest and fastest: the excellent Backbit Chip Tester Pro for a test and ROM dumps
Udo Juerss minimized the original monitor written by Alois Nachtmann by removing the socalled “assembler”.
And added Intel Hex and MOS Technology papertape upload.. Furthermore some routines can be use in own programs like: TTY_INIT, TTY_PUTC, TTY_PUTS.
Here an archive with the source, binary and documentation.

The Rockwell pages on AIM 65 have had some updates.
There is a new page on AIM 65 hardware produced by others, like video cards, dataloggers and more.

Multi-ROM adapters by Steve J.GRay
The PET/CBM MultiROM adapter is usable on the AIM 65 also. It gives a 4x DIP switch selectable choice of 16 ROMs. Handy in the B000 socket, where language ROMs are placed.
A 27512 EPROM holds the ROMs.
