For what it's worth, I've ordered several times from UTSOURCE and the results have been perfect. So far, I obtained a number of the Harris 'pdp8' chips D1-6120-9 and 6402 uarts plus Harris's weird baud-rate generator and 6121 'port' decoder. All have been quickly delivered and were 100% tested by me only receipt and they all met operational specs within specified voltage ranges. Surprised about shopping charges, though. I'm in the US and the shipping charges were quite 'nominal'. Less than $5 on a 25 chip order of about $150. They are so far, "good guys" in my book. -Gary Before I go with the ceramic part (IMO not the sort of packaging that gets . remarked) I thought that I would check here for alternative sources.

Seeking a MC75325L Dual Memory Driver
I have here in my hands a DEC H222A (16Kx18), part of a MM11-DP, that took a blow at sometime in the past. In consequence there are a number of small parts damaged (snapped diode, crushed axial electrolytic, chipped mica capacitor, cracked/broken SIP resister net) but those all appear to be relatively easy to replace. What's not so easy to replace is the MC75325L Dual Memory Driver (L = Ceramic) that was de-lidded in the process :-<. I am wondering whether anyone has one of these ICs in their spare parts drawer that I could acquire? I do see a MC75325P (plastic) on eBay at littlediode_components for ~20USD, plus a surprisingly modest shipping charge (Royal Mail International).
