The configuration for serial as shown on the ADTPRO website shows

SW1: 1001111 SW2: 1101100

With regard to SW2 numbers 3 and 4 (as read from left to right), they are shown to be configured as 01

Table 2-4 of the SSC manual shows

11 - no parity
10 - odd parity
00 - even parity

so what is 01?

Hmmmm, undefined, it would seem. The only two switches that actually matter are SW1 4 and 5 that put the card into communications mode (as opposed to printer mode). Everything else ADTPro needs is set up by soft switches.

What I do is set the switches for bootstrapping. This way you can bootstrap or do transfers. It's less work and more versatile.

Exactly... right or wrong (and it looks like it's wrong), those switch settings have been used successfully for years for both operations. We don't rely on the card to do parity checking for us.

Re: ADTpro with superserial DIP switch question

Yeah, what works, works. However Im still working on why my modem isnt operating correctly and came across this. While it may not apply to ADTpro im wondring if this could be my issue. All I do for modem is turn the arrow from terminal to modem. Its possible that this setting may be borking it

jrubin,

SS cards are really cheap. They're everywhere.
Have been for a long time.
Get a second one to use for your modem and
keep the one you're using for ADTPro.
That's what I did.

Re: ADTpro with superserial DIP switch question

Just out of curiosity. Exactly how many bytes are sent for the bootstrap?

Exactly: 4,116 text bytes are sent to kick off the bootstrapping. That boils down to a program 1,137 bytes in length. That program sniffs the serial hardware, figures out how to use it, and then kicks off the next of two stages in binary, at top speed: 1) downloading the ProDOS MLI (16,509 bytes) and 2) downloading the ADTPro client code (50,875 bytes).

Hmmmm. at 10 BPI......... Bootstrap 113.7 inches
Prodos 1,650.9 inches

1,764.6 total inches
/12

147 FT
Yeah, Nevermind , thats not gonna work...........

Re: ADTpro with superserial DIP switch question

Sorry, I quoted the text versions of the MLI and ADTPro... the actual binary bootstrap lengths of those two later items are 16,509 and 14,182 bytes respectively.

Re: ADTpro with superserial DIP switch question

I was trying to compute the length of paper tape I would need to load the program. You know, just because. But clearly it is way too big for such a feat as it would extend half the length of a football field.

Ive got a high speed (2400 bps) unit. but it would be a catastrophie to manage that kind of roll

LOL, and I thought audio was a bad idea!

31,828 bytes; 80 bytes per card; 398 cards. A reasonably large deck. Wink

Just for perspective, Altair 8800 - Video #7.1 - Loading 4K BASIC with a Teletype.

Woz's 1200-1500 bps Tape Loader was "Da Bomb" in 1976!!!!
