Tek4052 V5 ROMdumps available

[jos]

For the upcoming VCFe in Zurich / Switzerland (18/19 Nov )  I  repaired my TEK4052, which is now up and running ( no usable tapes yet...)

I took the opportunity to read all the programmable devices from the machine, you find these at ftp.dreesen.ch/ftp/TEK4052

They are release V5 for the ALU-(microcode), and release V5.1 for the MAS-(firmware) board.
They do not use patch-pla's, I believe them to be the latest revision for the 4052.
These are for the 4052, not the 4052A which is a different beast. (differnt IO and MAS board, different microcode and firmware )

As a reference, the romdump's at Al's site are for the 4052A, the romdumps at the Stuttgart museum site are the earlier release V4.x for the 4052

Take note : a 4052 does not boot without the tapedrive attached...

I also dumped the contents of both 2716's onboard the diagnostic rom pack. ( also containg a 6810 )

I have (untested) spare boards if anyone in the neighboorhood wants to try some boardswapping...
