I have been recovering dozens of old Tektronix 4050 series tapes and found one with Fast Graphics software for the 4051. This software program jumped into 6800 assembly code and retrieved three bytes per vector from a tape file. Apparently this tape is a duplicate - and it appears that all the files bigger than 1KB have corrupt data.
Apparently from the 4014 programmers guide - they had a set of demo picture files including a list with R2-D2. I have found Jos Dreesen's ftp tar file with some 4014 pictures - but I'm looking for an R2-D2 picture file that is on the tape I have but corrupt. I also discovered that Tektronix made a 4052/4054 R12 Graphics Enhancement ROM pack which included the Fast Graphics program in ROM. I would love to find one of those ROM packs - hint/hint :) I did recover one of the shorter picture files of Snoopy - but since I don't have a 4051, I can't run the Fast Graphics program on my 4052 or 4054. One of my buddies threw a C program together to convert the data file into Tek 4050 PRINT statements. I've posted the SNOOPY basic program and screenshots of running it on vcfed in a new thread: http://www.vcfed.org/forum/showthread.php?64726-Tektronix-4051-4052-4052A-4054-4054A-Program-Archives I'm also still looking for a 4051/4052 Display Board. Mike Haas posted pictures here in Oct 2016 of lots of Tektronix boards including a Display Board - but I don't have any direct contact info for him. Monty
