Ashton Tate was a name that had somthing to do with it and danged if I dont still have all the books on programming.. I believe it was called CPM (Critical Path Method?) It was set up for me by a guy who worked for me, in my printshop.

Did acount lists. receivables, 3 check books and accts payable and it was hooked into a cannono typwriter to do all the printouts from late 83 till june 88..

I knew nothing except how to enter and print it did all the adding and subtracting.

It had some games but didnt use very much for that..

havent turned it on sine 88 did it a few minutes ago and it came on but forgot how to access the durn thing.\

It cost 3,200.00 when I bought it in 88..

Things sure have cahnged; acception would be me I still KnoW ; next to nothing about computers

In fact, Bill Gates ported it over from the original 8080 processor to the 8086 (with a few changes) and sold it to IBM as PC DOS to be bundled with their IBM PC.

I've got a 486 machine and the cables you are welcome to use if you ever get up near abilene - - if you have the software lol, thats our current stopping point. We have looked into a few of the aftermarket/open source programs but would really prefer the actual motorola packet.

ETA - as far as I know it works fine - has been in a/c in my daughter's room - was her "math game" computer when she was little. We just never moved it off her desk.

Don't get you're hopes up: hasn't been powered-on since 2000, and it's been living in Houston attic conditions.

I'll pull it down and test it this weekend, but my bet bet is no-go, even if I switch out a new power supply.

I'll try, though. Think I even have an old, unused, 386 motherboard up there...

The fastest I recall an Intel 386 running was 25mhz (some amd based chips hit 40mhz) while the 486 started out at 16mhz and 25 mhz they got as fast as 133mhz IIRC. I suspect the 486DX will probably work while the DX2 and DX4 might give you heart burn due to the cpu clock being run on a multiplier off the bus clock. I am basing this off of what I remember on the 386 and 486 class processors as well as what you posted about bricking the radio. I could be, and probably am, wrong but I would be careful running the 486 machine.
