I see the Teletype logo on the machine but cannot identify it. It looks
"flat" like a model 43.

The article mentions The Source. I was an early subscriber to The Source.
I used a Lear Siegler ADM-1 terminal and a home brewed 300 bps modem
(XR2206 and XR2211) to call from San Luis Obispo CA to Santa Barbara CA
where I could get on a network to reach The Source. I think The Source
cost something like $5 per hour and the call to Santa Barbara CA was about
$7 per hour. I used this to write code for the MC6800. They had a cross
assembler for it. I then downloaded the S record file to my Sunrise
Electronics ZAP-80 EPROM programmer, burned an EPROM, and plugged it into
my wire wrapped prototype MC6802 system.

Eventually I got a Cromemco CP/M system and did assembly on that.
