Tek 40xx computer users

[Randy Dawson]

Thanks Pete.


The 4051 is working perfectly so far, with a few examples I have typed in.


I started a conversation with VintageTek (Dave Brown and Ed Sinclair) to see what they have.


I looked at the 'Toaster' schematics here, it should be fairly easy for me to build this one up:

Interesting, the source firmware is in the fiche directory, I have had some fun reading it, the comments are a hoot.


Next on the list, I will get a Kraft joystick and build that up, its a simple op amp integrator circuit (the more you move the stick, the faster the voltages ramp to the 4051)


thanks for anything you have, its a fun machine.


Randy

The ROM cart your going to want to get never left Tek, it had the capacity
to hold all the packs, another one is very high (for a 6800) performance
graphics.

To use multiple ROMs you will need a 4051 Toaster. That's what we called
it. Can't remember if it was a product or not.

I may have a couple original packs if I find them I'll extract the contents
and put them on bitsavers
