The ITC32 is a small single board controller that originally sold for about $400. Last price on it before it went out of production was about $150. Any of the modern single board repeater controllers (such as the ICS units) are much more versatile. The ITC32 was one of the first frequency agile remote base controllers however it only talks to a BCD controlled radio such as the Icom IC22U, Kenwood TR7400, TR76xx series, Yaesu FT227, Drake UV-3 and other similar radios.
The most recent information is that Mike WB8CXO is still supporting the ITC-32.

Considering replacing your old ACC Controller or want a new one that
works and programs similarly to your friend's ACC?
Take a look at the FF Systems FF-800 controller however they no longer manufacture or sell any products.
Need your ACC product repaired? Here's the place: (Paul repairs the RC-85s, 96s, 850s, DVRs and FC900s)

The RC-85 PAL "Faker"
When upgrading an RC-85 from something prior to V3.xx to V3.xx or later, the 74LS138 must be replaced with something else. ACC used a $150 PAL board to do the job, but you can do it by rewiring the 74LS138.
Years ago, I took a good pal from an RC-85 and hooked a dip switch to the inputs. By running all the bit patterns into the PAL and watching the outputs I came up with this design for the 74LS138. It is my opinion the PAL was just a way to try and copy protect the EPROM and/or get $150.00 from everyone.
I take two 16 pin machine pin IC sockets and plug them together. Take 4 short pieces of wire wrap wire and strip the ends back. Solder one wire into the socket pin 7, then another into socket pin 9, 10, & 11. You should now have 4 wires sticking up into the air from the socket. Take the 74LS138 and bend up in the air pins 7, 9, 10, & 11. Now solder the wire from the ic socket pin 7 to ic pin 9. Socket wire pin 9 to ic pin 7. Socket wire pin 10 to ic pin 11. Socket wire 11 to ic pin 10.
This has worked for me in the past. I have the 2 pals I got from ACC back on 4/11/95. They are GAL16V8B, my blown PAL shows the number PAL10L8NC (I think it's blown, my RC-85 is still not working yet).
I doubt they can be read, but I don't really think we need to. I think we can use the Faker or design our own PAL to do the same thing ACC's did.
GE Mastr II S-Meter Circuit. By Andy Kadvan KA8R from ACC Notes
This circuit samples the high-IF signal, rectifies it using a DC voltage doubler, then runs it through a simple op-amp based DC voltage buffer/amplifier. It's overly simplified and needs more development to be practical: several people have tried several variations of this circuit and all have the problem that it loads down the IF strip and therefore makes the receiver less sensitive.
Motorola Micor S-Meter Circuit. probably from ACC Notes, text by Mike Morris WA6ILQ
This circuit is similar to the GE one above, just adapted to the GE, and looks like it was designed around what parts were on hand. It has the same loading issue.
Hamtronics S-Meter Circuit. By Kevin K. Custer W3KKC
Kevin's circuit for the Hamtronics will work on any receiver that uses the Motorola MC-3357 or MC-3359 style IF amplifier / limiter / detector chip, and that includes a number of scanner receivers.
