This VTI is VLSI Technology, Inc and is NOT the company bought by Murata. The Wiki says: The company was later acquired by Philips and survives to this day as part of NXP Semiconductors. What he apparently has is a mask-programmed ROM with oddball chip selects like the old Bally pinballs used. I had attached a datasheet yesterday in this thread that wasn't the correct part, but DID have the correct logo on top of sheet 1 and the full company name on the bottom of the sheets.

Hmmm... I can see I attached a pic, but it didn't get through. Sorry about that. I have posted the pic here: http://www.tollianweb.com/uc/vti.jpg It's IC 1N from an Exidy 440 PCB (Whodunit in this case). I'd really like to identify the manufacturer. I looked at several IC logo web sites and nothing comes up. It's in a bank of 2764's and supposedly supposed to be able to be read as a 2764, but my EETools Top Max is unable to read it. Really a mystery to me why I can't find this symbol at all (and why if it is equivalant to a 2764 my reader can't read it). It's not a bad chip as the game boots up and passes all self tests without any complaining. If anyone might be able to identify what IC is on 6K on the same boardset type, that would be appreciated too. On my board, it's a National 74S28(x) where "x" is either a 7 or an 8, but it's overlayed with an Exidy part number stamp. National 74S287 crosses to an MMI 6301 (Signetics 82S129) and a 74S288 crosses to a MMI 6331 (Signetics 82S123). Trying to dump a Whodunit ROM version that's not in MAME.

Can anyone identify the chip in the attached picture? I cannot find the manufacturer's symbol or anything related to VTI. I found one source of VTI mentioning being acquired by Murata. I wrote to them and they told me it was a different VTI. It's in a bank of 2764's, but my EETools Top Max can't read it as a 2764. I would really like to find the manufacturer's name.

OS 6.1 and 9100/A/AF/FT - anyone using one of these?
by John Robertson 09 Nov '13

09 Nov '13

A note about OS 6.1 Fired up the 9100 with a pod attached, and you get the following message: "enabled line causes timeout" In case you are wondering that is normal response for the 9100 when it starts up with a pod. I suppose that is just reminding you about what timeout errors can be caused by. That is probably because the pods were developed long before the 9100 and thus the error messages left something to be desired... I've been using the 9010 for a long time and decided that seeing as I have a stack of 9100s I really should get to know them better so will be attempting to teach myself how to use this in place of the 9010 - the advantage might be the storage of results (including ROM images) should be easier with the 9100. Has anyone else used a 9100 and stuck with it, or returned to the 9010?

6502 pods & clocks....
by John Robertson 08 Nov '13

08 Nov '13

Tic, tock... The 6502 will clock from either a crystal or an R/C system. The problem with the R/C is the capacitor is only 10pf, so the cable capacitance will sloooowwwww the clock down somewhat (900kz to 500kz or so). So, being impatient I'm making a simple 74044 1Mhz R/C clock that fits into the Fluke adapter socket and will drive the UUT 6502 CPU directly, thus the pod won't interfere with the clock frequency and I won't get any more timeout errors (I hope).
