I have the exact same board, mine had a barrel battery. Can you give me a good clean shot of the battery area so that I can cross check? From what I can tell only the diode on D14 and resistor on R12 are missing, I'd be delighted to learn I can just remove those and slap on a battery holder onto this!

I know this is a tad overdue but THANK YOU! My board finally has been modded with a CR2032!

Now, do I use this or a Biostar MB8433UUD-A for my 5x86 build 😀

Picked up this TOP853 on eBay, has only been used twice and is virtually new in box. Looking forward to repairing some of my motherboards and graphics cards, plus dumping some ROMs using this.

Not exactly vintage in itself, but will be used extensively for Vintage purposes. This is one of those gadgets, like a 'scope, where you reach a certain level and just need one. Actually been searching for a good priced one for a long time.

It is AST Advantage Explorer.

Unfortunately It does not start with anything inside self pcmcia slot (probably it supports very old pc card format), so that why I need to use LPT adapter instead of internal slot.

Total ram about 4mb (with 640Kb).

I think I asked you the same question already in the pcmcia sound cards thread some time ago...

Could you take a picture of the ram expansion port?

This card arrived today. It's a Tseng ET4000AX VLB. I believe that the ET4000AX chip was manufactured in the 12th week of 1992.

I'm not sure of the OEM, but it is apparently an "Eng. Sample." NSSI recognizes it as a 1MB Tseng card. It works perfectly, and the colors really pop.

I just received this. It's in a sorry state. But it was almost free, so I took it. I don't even know if it works.

Honestly those are the best aquisitions, imho. And if it doesn't work, making it work is SO satisifying.

It is a mistake to think you can solve any major problems just with potatoes.

That's cool. Looks like a very early VLB device. I have ET4000AX of about the same age. But that's a pre-VESA local bus implementation.

That's so true. I'll test the module tomorrow.

I have what I believe to be the production version of this card on the way. It even comes with a manual and drivers, so I should know more about its branding soon. I think it is a "generic" OEM and not one of the big-name companies.

Yes, the ET4000AX shows its ISA lineage in my benchmarking. It's about 10% slower in Superscape and Doom than my other VLB cards (Cirrus, NCR, ET4000/w32p).

Well, I won this strangely, and possibly Tandy 1000 compatible LightPen on E-bay today. No real basis except that it uses a DB-9 female port and I have enough electronics skills to backup actually figuring out the pinout and looking at the circuit. I'm kind of hoping it's one of the "Warp Speed" light pens - the connector looks right and it looks like some documentation pictures - and I have the software from some experiments. Will check the pinout first - since I have the Tandy's pinout for the lightpen port written down in my desk from my experiments last summer (where I almost make a working one but was having trouble with tracking being very consistent or working at all).

This came in the mail today:
DSC-0393.jpg
Sound Blaster 16 CT1740

It was listed as untested/not working and I got it for a steal. Sadly, it's got one of the "hanging note bug" DSPs.
Even more sadly, it doesn't seem to output anything on the left channel. It might just be a matter of applying some contact cleaner to the speaker OUT jack, but since it's got the hanging note bug and since I use external MT-32/MIDI I'm not really inclined to replace my AWE64 just to get better FM music. I'll store it away for now and revisit it at a later date, once I eventually get a dedicated MPU card clone, etc.

I decided to collect the missing Chips for my junk AMIGA A2620 card
Bought these (retro) hardware today

I got all 3 from different sources and at the end I paid a lot of money for them (incl. shipping..):
68882 22,50€
68851 30€
68020 11,5€

Hope I get it working, did not test anything so far...

Today I took the time to make a short test of my 68020 Turbo-Card:

But I have to admit I had to close J303 to disable Fast-Ram...without that an error appears.

Same on my models, except I have the 4M ram expansion in each, and somehow I have one half of the 16M expansion.

Got this macintosh Color Classic today. Seller said the condition is unknown. Usually when I see that said, I assume the seller knows it's broken. So I sent him a real low offer, and to my surprise he accepted. This time it was nice exception, it booted right up.

Seems quite dirty, but everything is intact. No cracked plastics or anything, no big scratches, no burn in. It isn't even yellowed. Some sticker glue residue in couple of places. I think after good cleaning this will look really nice. Now only if I had mouse and keyboard for this 😒

Screen has slightly darker area in the upper right corner. Other than that, it is really sharp and good looking. Seeing that it has finnish language operating system is nice.

ADB mice and keyboards are expensive . There is also this https://www.bigmessowires.com/usb-wombat/ , if you want to use USb peripherals instead . Less authentic, more practical , IMHO .

That CRT might need to be degaussed, also, I'd recap the whole machine if I were you, some compact Macs were known for suffering from leaky SMD capacitors.

On top of my head I know that the following compact units are affected (I'm excluding the other Macs) :

  • Macintosh SE/30 (the SE seems to be unaffected)
  • Macintosh Classic
  • Macintosh Classic II
  • Macintosh Color Classic (not sure about the "obscure" Color Classic II)

The older (128K, 512K, 512Ke, Plus, Plus/ED, OG SE and SE FDHD) could benefit from a analog board recap and the replacement of the axial caps that they use (which didn't go bad as much as the SMD shitcans used on later 68K units).

Also careful about that PRAM battery, these are known for exploding and often taking the logic board with them.

Proud owner of a Shuttle HOT-555A 430VX motherboard and two wonderful retro laptops, namely a Compaq Armada 1700 [nonfunctional] and a HP Omnibook XE3-GC [fully working :p]
