I'm planning connect my HP1000 to ASR-33, so I could play with it for real...but only problem: I have no TTY board :( 

Anyone have spare for sell/exchange/donate? I might consider give up my Grumman HP1000 SCSI controller board in exchange...

Also I'm interested other boards (X&Y and RS232), peripherals and etc. HP stuff...
