This machine came from the USA, it was built by
Forethought Products who advertised a few AIM 65 related items back in the day.
It had a rather nasty USA spec. PCB power supply which I removed and replaced with a modern +5V/+24V switchmode.
Its interesting because underneath the AIM 65 mainboard there is a card cage which accepts S44 sized cards, there was an S44 prototyping card fitted with a handful of components, unfortunately the wiring between the card and the AIM 65 had been cut so I couldn't work out what it had been used for ?, the EPROM in socket Z24 was labeled 'Temperature Control Patterson" ?
The front panel had a couple of small PCB's with LED's attached and some circuitry, I havn't worked out what any of it it does (here's a schematic :AIM 65 Forethought Products Schematic.pdf). I've just wiired up the Reset and STEP-RUN switches and a Power LED, the Parity, Write and Step LEDs are blank.
As luck would have it I have a BETA Computer Services 32K Dynamic RAM board that is S44 so I have rigged that up underneath the AIM 65. I had to make a small backplane to convert the AIM 65 Expansion Connector to the S44 pin out.
This is my favourite cased machine - an Italian design by G.Gurioli and manufactured by Teko, Bologna. It has its original (UK spec) linear power supply which still works fine.
This computer came as just the mainboard, no keyboard or case so I had to make a Replica Keyboard and screwed it down to a wooden baseboard, this is actually the machine I mostly use because of the easy access !
There is a modern +5/+24V switch mode underneath.
Here is my Vero version of an RM 65 Rack, its usually connected to my 'Woody' AIM 65 via an RM65-7116 Cable Driver Adapter Buffer.html.
It is fitted with an RM65-3108 Static RAM Module, RM65-3132 32k Dynamic RAM Module, RM65-5102 CRT Controller Module and RM65-2910 PROM Programmer Module.
