Very little is known about the A3500 as it was never officially released, however an unknown number of models certainly found there way to dealers and end-users. Apparently, the A3500 was originally designed for Sun Microsystems to run UNIX on, who would have rebadged the machine and sold it as a Sun product. In true Commodore style, the deal fell through. This seems a likely cause for the A3500 never being officially released and eventually ending up being sold as the A3000T which is almost identical, apart from a slightly different case bezel and some minor differences mentioned below.
In Commodore's tradition of whacky naming schemes the A3500 does not carry the "T" designation that their other tower systems do. The A3500 was previewed at the Business Computing show in 1991 and can be seen in the "Deathbed Vigil" video by Dave Haynie. The A3500 came with an 030@25Mhz and 68882@25Mhz on the motherboard. It seems unlikely that any machines were supplied with an 040 as the true A3000T was released shortly afterwards. The A3500 has the same SCSI-II controller as found in the A3000T and the desktop A3000 and also contains the same built in scandoubler.
There exists one early prototype A3500 that has a blue motherboard and even a blue zorro slots and jumpers which is quite unusual as most other Amiga's have the traditional green motherboard and black Zorro slots. The A3500 with blue motherboard shown here belongs to Treveur Bretaudiere.
Unlike the A3000T, the A3500 lacks a CD-ROM audio connector for mixing in the sound output of a CDROM, however it has two hard disk LEDs, instead of one and a power LED. The actual A3500 case is based upon a tower case which Commodore used with one of their PC systems (PC 60) but had a different name plate and an extra externally accessible drive bay. The case is also similar to the A3000 case, with the front bezel being different. The A3500 also includes an internal speaker for playing the native audio, however external speakers can still be attached.
