gk care to share more info on your heathkit?

as i know verry little about function generators but i assume it is a tube generator that you have used on or with the tpu what were your results? ahd why do you insesist on ss?will tubes not be the easyest to get something to work?

well right after i saw the bordar land sciences vid i was sure tubes were best and easyest to work with steven has said that and many others too 

just windering what you think

is

Heathkit is an analog 10mhz single trace with 'Y' channel addition. The 16 trace feature I built as an addition to an 8 trace schematic I got from Byte magazine in 1980. It is comprised of a 555 timer to a 16 to 1 multiplexer which connects to the 'X' channel. I post it because now I have 18 traces to look at. Keep adding muxes and up your trace count. Its like having a cheap signature scope for ttl digital signals.
You could also incorporate analog muxes and opamp buffered interfaces for other signal types. http://pdf1.alldatasheet.com/datasheet-pdf/view/72684/MAXIM/DG506ACJ.html
You could also make a board per scope channel and get 32 channels without a redesign!
This board is sweet!

Soiled state:
I use solid state because I have seen no other results yet to deter me from that. I throw it together and turn it on. Cheap, fast and easy. I usually go from paper straight to solder.
Also as a safety warning:
The noise injected by the solid state can or could set the TPU into runaway should any of the new signal get on the center frequency.
Anybody else got the safety circuit built that I designed and posted? There have been others along the way also by other members that watch the voltage, thermal, or current. Or just add a tank circuit inline to block the center frequency.

Winter is coming so I thought I would stuff the nest for things to do during hibernation.
www.Futurlec.com is great. I am steering towards the pic18xxx series for speed. I will hook the 3-16 bit output timers to my fet driver board. For a speed up to 10mhz for $36.00USD. This equates to a 70pin function generator.

And download the free IDE assembler from here.

@Giantkiller

http://www.futurelec.com/ is nothing but commercials/links?
- I can't find any PIC chips there anyhow.

But on a different note I'd like to recommend that you take a look at Atmel's ATMega series before you commit. http://www.atmel.com/dyn/products/param_table.asp?family_id=607&OrderBy=part_no&Direction=ASC
I think they're nice to work with. A nice compiler can be found at http://www.hpinfotech.ro/  (Supports code to 2 kb as a trial version - includes some nice libraries)
I found a cheap JTAG interface/programmer, which also is integrated in AVR Studio (IDE), at miklobit:
http://www.miklobit.com/JTAG_TWICE.530+B6Jkw9Mw__.0.html
Cost is ?46,47 incl. shipping
Once you've gone JTAG you'll never return 

Btw - I've found that Microchip's MPLAB ICD2 is pretty unstable, but I could have been unlucky

Happy hunting

@TheDane,
http://www.futurlec.com   !!!! No E on future. Sorry. Damn squatters!
The green side bar on the left has the product links.
