Can you clue me as to where on the site to preorder or do I keep checking in? I also went on DISCORD but no answer there either... :cry:

At this point, I would pay what they ask if only I could find one, the mini appears to be an excellent replacement from what I can read and vids I've seen.....actually I'd buy two.....

Yes, it does fail as I have two boards of the same version, of which one has a bad VIC, swapped all configurations on both boards and used diagnostics cartridge and with my good VIC, they worked perfectly, even using a 1541 loading programs and running, and a cassette loading different programs...

Thanks Robert, but I already got the ceramic version from him, it, unfortunately is also foobar, I'm trying to get it returned now as we speak..... I will also accept a 8562 - it is the C64c version, I'm told just replace pin 13 12v with 5v and your good to go - but alas, no 8562's to be found...

Any chance you might share where to purchase? Everywhere I look has "Out of stock" 😢

Hi all, I have a couple of C64's in need of the VIC II 6567 chip. Since these are long boards, the VIC II 8582 would also work. I can find PAL versions, but not many NTSC. I checked out the KWARI replacement, but no info on yet on when they will begin on the NTSC version. Thanks Howard W1ARQ

Nice buy, my friend! Very good catch considering the age, and super clean. I have 3 of these, a Kaypro 2, a Kaypro II and a Kaypro 10 - the K10 was water damaged (the keyboard was submerged in flood water), and the hard drive was "frozen", but I managed to save it and it runs great now. I envy...

Which drive are you booting from, A: or C: (C:=hard drive if you have one installed)? If you boot from C:, it does not know where to get the config.sys and autoexec.bat, so DOS just drops to a default prompt.

Based on the edge connector pin count, that appears to be an slightly modified STD bus, there is a spec that defines this: https://en.wikipedia.org/wiki/STD_Bus that may give you clues as to what it is. It most definitely is not S-100

Bingo, a clock chip, hence the battery....... The 58167 also has a few bytes of battery backed ram for keeping tid-bits of config info for the card when the power is off..... all of which I suspect is unavailable to the host (PC) directly because it wouldn't know how to execute Z80 code, the...

Yup, my bet is that it is Digi's answer to the Comtrol RocketPort EXPRESS card which is a multi-port serial interface card for use in a XT or AT running Unix or Xenix or some equivalent multi-user operating system. Xenix was to more popular for the smaller architecture of the 86/88 that has a...

Actually, I'm looking for anything by Technical Design Labs or TDL, as in the SMB1, Xitan chassis, Z80 ZPU, including software as well. Also, any kind of S-100 cassette interface board, particularly Tarbell, but all offerings considered. Thanks, Howard W1ARQ

What are you asking for the trainer? Thanx

Hello, are any of these items still available? Thanx

That's a keeper for sure....(y)

Hello, I have a IMSAI MDS DIO Floppy Disk Controller S-100 card, but unfortunately the PDS (Programmable Data Separator) daughter board has been, well, separated from the DIO card. I'd be interested in purchasing even a dead set for repair. Also looking for any Technical Design Labs cards and/or...

And with shipping it pushes it to almost $300.00, didn't it cost that much in 1976 (taxes from my state WILL push it over $300.00) ; nevertheless, I'm kinda tempted :unsure: because it is easy to use - I had one back in the early 80's and it was a breeze to setup for CP/M and Wordstar...

Hmm.... :unsure: there's a thought, but apparently the 3.30 version I got hold of is already changed by MicroPro, as I get this during install.... 😞 Selection "B" also returns this result. It is version 3.30 but already warmed over by MicroPro, I suspect that the patch area for the terminal is...

Manage to acquire an IMSAI MDS DIO S-100 floppy controller, but unfortunately it is missing the PDS (Programmable Data Separator) board. I would be interested if someone has one to trade/sell. Thanx for your time......W1ARQ

There is a VDM on eBay as of this writing, but I thought the price was a little high. I would like to talk to you about the SA800, if it's still available. I have an SD SYS FDC, but unless I can locate a PDS to go with an IMSAI MDS DIO, I probably will hang on to this.
