Reposting this because I didn't get a single reply on or off list. Did it in fact make it to the list the first time? --------------------------------------------------- I have an ML4100 that has and is serving me well. I have most of the various pods and ROMs for it and duplicates of many of them. Two things I'm missing (based on my reading of the documents) are an RE-016 ROM emulator (with RS-232 interface) and an AB-032 non-volatile memory. Anybody have either of these that they might be convinced part with for trade or cash? Non-working would be fine. I enjoy troubleshooting. Alternatively, any explanations of why they are not very useful or worth having at all would also be of interest.

Willem EPROM programmer...
by Bill Sudbrink 09 Jun '09

09 Jun '09

I'm new to the list. I collect and repair/restore 8-bit microcomputers from the 1970's. I'm considering picking up one of the Willem EPROM programmers that seem to always be available on ebay for pretty cheap. I've gone through the list archives and see that there was a discussion on this subject several years ago but it didn't really come to any firm conclusion. My main use for this tool would be to program 2716s and 2732s. One of the tables in one of the ebay pages suggests that the device can test 6116 static RAMs which would also be useful. I have two concerns: 1) All of the ebay pages emphasize all of the new chips that these gizmos support. Has the "legacy" chip support been lost? 2) Whenever old programmers in good shape come up for auction, they go for a lot more than the "buy-it-now" on these Willems. Why?

Wierd behavior with simple Fluke script
by Adam Courchesne 02 Jun '09

02 Jun '09

I made a simple block write script so I can write blocks of data to video memory to make it easier for me to find shorted/floating bit lines etc. The weird thing is, as soon as execute it and it finishes I can no longer write to video memory. For example, if reset a given PCB, see garbage on the screen and execute my scrip, writing all 0's to video memory, the screen is wiped clean. (As expected) Then if I try to write values to video mem to place a sprite at a given location ... no luck. Leave the game on.. reset the fluke... and try the same write again, and it works. So something in the script is putting the Fluke into a weird state. Any idea what could be causing this? Here's the script: SETUP TRAP ACTIVE FORCE LINE NO TRAP ACTIVE INTERRUPT NO PROGRAM MAIN DPY-# DPY-BLOCK WRITE PROGRAM EX DELAY ! Get start and end addresses DPY-START ADDRESS = /1 DPY-END ADDRESS = /2 DPY-DATA = /3 DPY-WRITING DATA# WRITE @ REG1 = REG3 WLOOP: WRITE @ REGF INC = REG3 ! DPY-WRITING $3 AT $F ! EX DELAY IF REG2 > REGF GOTO WLOOP DPY-END OF PROGRAM# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! DELAY ROUTINE PROGRAM DELAY REG1=40 0: DEC REG1 IF REG1 >0 GOTO 0 Thanks for any insight, -- -Adam "Please don't judge my God by my inability to follow him" - Chris Mollins =============== www.onecircuit.com www.youtube.com/user/ajcrm125 =============== _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

UDN6118A vs UDN6118P
by barry2＠shilmover.com 01 Jun '09

All, I found some old Williams display boards with UDN6118P chips on them. I could not find a pdf for them. what are the differences between the A and P chips? Are they interchangeable?
