I believe you got the first one, and the tracking indicates it'd be in your country already. 😄 Which is good, as I'm now out of stock! But more PCB's arriving Monday hopefully. 🤓
Great idea using the 63C09 PLCC to minimise PCB footprint. I ordered some 63C09EC ic’s from eBay after watching your earlier video on these parts, unfortunately they were fakes as the labels rubbed off with the acetone test 😢 It appears the genuine PLCC parts are sadly difficult to source.
@@michaelboyd9434 Yes, indeed. I’ve had the same problem sourcing “recovered” retro parts in general. Particularly EPROMs, and also 6x09E parts incorrectly re-marked as 6x09P (which I did a couple of videos on). It’s why I also offer a pre-tested PLCC CPU option with the 6309 PLCC CPU Card PCB (for as long as I have some tested good ones in my stock!). Did your acetone test reveal what the chips actually were (if not 63C09EC)?
@@DigicoolThings I watched your earlier video on fake IC’s and it’s very informative. The fake 63C09EC parts I ordered, when rubbed down with acetone produced a lot of black paint on the Cotton pads and appeared to have been sanded down to the extent that the previous markings are no longer visible. Another dubious observation was that the fake identification markings had also left residue on the clear plastic film that covered the plastic chip carrier packaging, so clearly white paint rather than genuine etched marks. Unfortunately I’ve not tested the IC’s yet as I haven’t made a suitable PLCC to DIP adapter yet. I wonder what the IC’s actually are!
@@michaelboyd9434 Interesting. Please let me know when you've had the opportunity to test them in-circuit. I have had occasions (especially with EPROMs, which I frequently order), where Acetone has proved that the chips were re-marked, but underneath, the revealed original markings were in fact the correct device. I can only ascertain that (at least in these cases), the re-marking had been done simply to "pretty up" the chips for sale. Still annoying, as I'd prefer just the original un-retouched recovered old chips! Often I find re-marked EPROM chips are actually different manufacturer and (annoyingly), slower access speed than advertised. However, in the case of EPROMs, especially for old device repair, as long as they are fast enough for the intended application (and a pin compatible equivalent), thay are fine. Obviously not so for 'E" suffix 6x09 that are re-marked as non 'E' suffixed!
Yes, I’ll let you know when i eventually get around to testing them. An Interesting suggestion that you make that they may indeed be the actual original parts remarked. Interestingly also that an internet search only seemed to find the PLCC option available as an HD63C09ECP although my parts arrived ‘remarked’ as HD63C09EC ?? The pin out on the data sheet I have seems to suggest only the internal clock ‘P’ version was manufactured as a PLCC part, Any ideas?
@@michaelboyd9434 I only found the one datasheet with the PLCC pinout. It was the HD63B09 / HD63C09 datasheet with the PLCC pinout on the first page, under “PLCC Package Available” heading. This datasheet is specifically for the internal clock variety (so probably the same one you found), but the ICs that I have are definitely ‘E’ variants. Although I haven’t yet found any “ordering information” (to explain the suffixes), I had assumed the ‘ECP’ would translate to: External clock / PLCC / Plastic package. i.e. Only the ‘C’ addition to the typical ‘EP’ External clock / Plastic package DIP variant. Perhaps an ‘EC’ only suffix notation drops the ‘P’, as Plastic packaging is self evident from the PLCC. But, I’m only guessing. 🤔 n.b. I have both ‘ECP’ marked, and ‘EC’ only marked, parts.
Good point! Apologies, I overlooked mentioning that I have a standard PLCC32 to DIP32 Adapter, which I use with my TL866II+ programmer. I believe the Adapter came with my first TL866 programmer, when I originally ordered one along with an assortment of bundled Adapters. Interestingly, I now own all of the TL866 family of programmers, as I've needed to test them with my own TL866 Adapter (for 27C322 & 27C400 /800 /160 EPROMs). The TL866II+ model is still my favourite for daily use! 🤓
looking good, nice new / retro string in your bow.
Yes, I seem to have grown a real liking for PLCC packaged chips in the retro space! Nice to insert, compact in size, but still TH retro friendly! 🤓
WooHoo!! :D :D :D Wait,.... Dagnabbit!! -_- has my parcel left already??

Can you saw which eprom programmer you use for plcc?
