Finally had some time to dig out my old Victor eproms and dump them. I have attached a zip file with all of 512k firmware images that I have, all require a 27C512 eprom.
It contains the following:
IQ-Industrial (requires hardware modifications)
IQJunior
IQ8Racer
SuperIQ2
SuperIQ2b (newer version)
SuperIQ2FCC
IQ3
IQ3000
IQ3000 with power on password set to 1234
If you load the IQ3000 with password file into a hex editor and go to address 0x7734 you can see the 4 digit password. The 4 bytes before it are what enable the password. Be aware not all 4 digit combinations seem to work(I haven't looked into why). The password can be enabled on all versions but the addresses to edit varies.
The original Hi-IQ and Hi-IQSr used 27C256 eproms, none of this firmware is compatible with early hardware without a memory expansion board or equivalent hardware mods to the main board.
I have attached a picture of a factory memory expansion board as well as an original serial adapter. The IQ can be fully remote controlled via serial port using a very basic terminal interface. There was also PC control software with basic graphing produced by Victor. Somewhere I also have the original motor com tuner plugin as well.
I had a Victor cell zapper but sold that long ago. That would apply a current pulse to a cell or battery pack of up to 99 volts.
There is also a dead cell revival feature in some firmware versions which hits a cell or battery pack with 40 amp pulses, this only required newer IQ main board hardware. It was a good feature to cook your charge MOSFET's.
I don't believe I have the documents anymore but to go from the earliest hardware rev to the last hardware rev requires a few MOSFET'ss, super capacitor, a diode, a resistor network, and few other resistors. Several PCB traces need to be cut and jumper wires run. It also requires a second current sense resistor. The earliest hardware revs also had a different power supply that wasn't as good.
The Industrial IQ is similar but used a current sense resistor that was 10 times the value(with a few other small changes) which gave it 10 times the current resolution but limited it to a charge/discharge rate of 10 amps. It also had provisions to charge lead acid/lithium cells. I don't recommend using it with lithium as it is missing safety features and has some very serious bugs. It does not support any motor tuning/break-in features.
The IQ3/3000 was introduced by Maxtec after they bought the remains of Victor Engineering. In the firmware I run I have edited out the Maxtec name as I was never a fan. I also run the original black face plate on mine instead of the silver or red.
The IQ was a real blast back in the day, we had Sanyo 1200 mAh SCR NiCads and we tortured them. If you charged them at 30 amps you could get the ends of the cells to bubble out which lowered the internal resistance and would give more capacity. This did shorten the useful number of charge/discharge cycles the cells could provide.
I also recall charging Sanyo 600 mAh AA industrial cells at 10 amps for fun - those were some tough cells!
No other charger could match the power the Hi-IQ could extract from a battery pack, its secret was that it charged with linear constant current. It did not use PWM for charge or discharge which was its huge advantage. NiCAD and NiMH cells never respond as well to PWM charging.
Victor Engineering also made electronic speed controls, and a 4 wheel balance car tuning system. Somewhere in the lab there is an original Victor Engineering racing banner and my decal collection still has many original decals.
Lastly all of the Victor's had the numbers of the chips ground off. Near the end some were produced without this "feature", by this point I had already made a list of all chips.
There is nothing rare or uncommon, the processor can be tough to find today though.
Chip list as they are placed on the main board:
